23.0 Scope and application.

(a) These guides apply to jewelry industry products, which include, but are not limited to, the following: gemstones and their laboratory-created and imitation substitutes; natural and cultured pearls and their imitations; and metallic watch bands not permanently attached to watches.1 These guides also apply to articles, including optical frames, pens and pencils, flatware, and hollowware, fabricated from precious metals (gold, silver and platinum group metals), precious metal alloys, and their imitations. These guides also apply to all articles made from pewter. For the purposes of these guides, all articles covered by these guides are defined as "industry products."

(b) These guides apply to persons, partnerships, or corporations, at every level of the trade (including but not limited to manufacturers, suppliers, and retailers) engaged in the business of offering for sale, selling, or distributing industry products.

Note to paragraph (b): To prevent consumer deception, persons, partnerships, or corporations in the business of appraising, identifying, or grading industry products should utilize the terminology and standards set forth in the guides.

(c) These guides apply to claims and representations about industry products included in labeling, advertising, promotional materials, and all other forms of marketing, whether asserted directly or by implication, through words, symbols, emblems, logos, illustrations, depictions, product brand names, or through any other means.

23.1 Deception (general).

It is unfair or deceptive to misrepresent the type, kind, grade, quality, quantity, metallic content, size, weight, cut, color, character, treatment, substance, durability, serviceability, origin, price, value, preparation, production, manufacture, distribution, or any other material aspect of an industry product.

Note 1 to 23.1: If, in the sale or offering for sale of an industry product, any representation is made as to the grade assigned the product, the identity of the grading system used should be disclosed.

Note 2 to 23.1: To prevent deception, any qualifications or disclosures, such as those described in the guides, should be sufficiently clear and prominent. Clarity of language, relative type size and proximity to the claim being qualified, and an absence of contrary claims that could undercut effectiveness, will maximize the likelihood that the qualifications and disclosures are appropriately clear and prominent.

23.2 Misleading illustrations.

It is unfair or deceptive to use, as part of any advertisement, packaging material, label, or other sales promotion matter, any visual representation, picture, televised or computer image, illustration, diagram, or other depiction which, either alone or in conjunction with any accompanying words or phrases, misrepresents the type, kind, grade, quality, quantity, metallic content, size, weight, cut, color, character, treatment, substance, durability, serviceability, origin, preparation, production, manufacture, distribution, or any other material aspect of an industry product.

Note to 23.2: An illustration or depiction of a diamond or other gemstone that portrays it in greater than its actual size may mislead consumers, unless a disclosure is made about the item's true size.

23.3 Misuse of the terms "hand-made," "hand-polished," etc.

(a) It is unfair or deceptive to represent, directly or by implication, that any industry product is hand-made or hand-wrought unless the entire shaping and forming of such product from raw materials and its finishing and decoration were accomplished by hand labor and manually-controlled methods which permit the maker to control and vary the construction, shape, design, and finish of each part of each individual product.

Note to paragraph (a): As used herein, "raw materials" include bulk sheet, strip, wire, and similar items that have not been cut, shaped, or formed into jewelry parts, semi-finished parts, or blanks.

(b) It is unfair or deceptive to represent, directly or by implication, that any industry product is hand-forged, hand-engraved, hand-finished, or hand-polished, or has been otherwise hand-processed, unless the operation described was accomplished by hand labor and manually-controlled methods which permit the maker to control and vary the type, amount, and effect of such operation on each part of each individual product.

23.4 Misrepresentation as to gold content.

(a) It is unfair or deceptive to misrepresent the presence of gold or gold alloy in an industry product, or the quantity or karat fineness of gold or gold alloy contained in the product, or the karat fineness, thickness, weight ratio, or manner of application of any gold or gold alloy plating, covering, or coating on any surface of an industry product or part thereof.

(b) The following are examples of markings or descriptions that may be misleading:2

(1) Use of the word "Gold" or any abbreviation, without qualification, to describe all or part of an industry product, which is not composed throughout of fine (24 karat) gold.

(2) Use of the word "Gold" or any abbreviation to describe all or part of an industry product composed throughout of an alloy of gold, unless a correct designation of the karat fineness of the alloy immediately precedes the word "Gold" or its abbreviation, and such fineness designation is of at least equal conspicuousness.

(3) Use of the word "Gold" or any abbreviation to describe all or part of an industry product that is not composed throughout of gold or a gold alloy, but is surface-plated or coated with gold alloy, unless the word "Gold" or its abbreviation is adequately qualified to indicate that the product or part is only surface-plated.

(4) Use of the term "Gold Plate," "Gold Plated," or any abbreviation to describe all or part of an industry product unless such product or part contains a surface-plating of gold alloy, applied by any process, which is of such thickness and extent of surface coverage that reasonable durability is assured.

(5) Use of the terms "Gold Filled," "Rolled Gold Plate," "Rolled Gold Plated," "Gold Overlay," or any abbreviation to describe all or part of an industry product unless such product or part contains a surface-plating of gold alloy applied by a mechanical process and of such thickness and extent of surface coverage that reasonable durability is assured, and unless the term is immediately preceded by a correct designation of the karat fineness of the alloy that is of at least equal conspicuousness as the term used.

(6) Use of the terms "Gold Plate," "Gold Plated," "Gold Filled," "Rolled Gold Plate," "Rolled Gold Plated," "Gold Overlay,'' or any abbreviation to describe a product in which the layer of gold plating has been covered with a base metal (such as nickel), which is covered with a thin wash of gold, unless there is a disclosure that the primary gold coating is covered with a base metal, which is gold washed.

(7) Use of the term "Gold Electroplate," "Gold Electroplated," or any abbreviation to describe all or part of an industry product unless such product or part is electroplated with gold or a gold alloy and such electroplating is of such karat fineness, thickness, and extent of surface coverage that reasonable durability is assured.

( Use of any name, terminology, or other term to misrepresent that an industry product is equal or superior to, or different than, a known and established type of industry product with reference to its gold content or method of manufacture.

(9) Use of the word "Gold" or any abbreviation, or of a quality mark implying gold content (e.g., 9 karat), to describe all or part of an industry product that is composed throughout of an alloy of gold of less than 10 karat fineness.

Note to paragraph (b) 23.4: The provisions regarding the use of the word "Gold," or any abbreviation, as described above, are applicable to "Duragold," "Diragold," "Noblegold," "Goldine," "Layered Gold," or any words or terms of similar meaning.

(c) The following are examples of markings and descriptions that are consistent with the principles described above:

(1) An industry product or part thereof, composed throughout of an alloy of gold of not less than 10 karat fineness, may be marked and described as "Gold" when such word "Gold," wherever appearing, is immediately preceded by a correct designation of the karat fineness of the alloy, and such karat designation is of equal conspicuousness as the word "Gold" (for example, "14 Karat Gold," "14 K. Gold," or "14 Kt. Gold"). Such product may also be marked and described by a designation of the karat fineness of the gold alloy unaccompanied by the word "Gold" (for example, "14 Karat," "14 Kt.," or "14 K.").

Note to paragraph (c)(1): Use of the term "Gold'' or any abbreviation to describe all or part of a product that is composed throughout of gold alloy, but contains a hollow center or interior, may mislead consumers, unless the fact that the product contains a hollow center is disclosed in immediate proximity to the term "Gold'' or its abbreviation (for example, "14 Karat Gold-Hollow Center," or "14 K. Gold Tubing," when of a gold alloy tubing of such karat fineness). Such products should not be marked or described as "solid" or as being solidly of gold or of a gold alloy. For example, when the composition of such a product is 14 karat gold alloy, it should not be described or marked as either "14 Kt. Solid Gold" or as "Solid 14 Kt. Gold."

(2) An industry product or part thereof, on which there has been affixed on all significant surfaces, by any process, a coating, electroplating, or deposition by any means, of gold or gold alloy of not less than 10 karat fineness that is of substantial thickness,3 and the minimum thickness throughout of which is equivalent to one-half micron (or approximately 20 millionths of an inch) of fine gold,4 may be marked or described as "Gold Plate" or "Gold Plated," or abbreviated, as, for example, G.P. The exact thickness of the plate may be marked on the item, if it is immediately followed by a designation of the karat fineness of the plating which is of equal conspicuousness as the term used (as, for example, "2 microns 12 K. gold plate" or "2 12 K. G.P." for an item plated with 2 microns of 12 karat gold.)

Note paragraph (c)(2) to paragraph (b): If an industry product has a thicker coating or electroplating of gold or gold alloy on some areas than others, the minimum thickness of the plate should be marked.

(3) An industry product or part thereof on which there has been affixed on all significant surfaces by soldering, brazing, welding, or other mechanical means, a plating of gold alloy of not less than 10 karat fineness and of substantial thickness5 may be marked or described as "Gold Filled," "Gold Overlay," "Rolled Gold Plate"or an adequate abbreviation, when such plating constitutes at least 1/20th of the weight of the metal in the entire article and when the term is immediately preceded by a designation of the karat fineness of the plating which is of equal conspicuousness as the term used (for example, "14 Karat Gold Filled," "14 Kt. Gold Filled," "14 Kt. G.F.," "14 Kt. Gold Overlay," or "14K. R.G.P."). When conforming to all such requirements except the specified minimum of 1/20th of the weight of the metal in the entire article, the terms "Gold Overlay" and "Rolled Gold Plate" may be used when the karat fineness designation is immediately preceded by a fraction accurately disclosing the portion of the weight of the metal in the entire article accounted for by the plating, and when such fraction is of equal conspicuousness as the term used (for example, "1/40th 12 Kt. Rolled Gold Plate" or "1/40 12 Kt. R.G.P.").

(4) An industry product or part thereof, on which there has been affixed on all significant surfaces by an electrolytic process, an electroplating of gold, or of a gold alloy of not less than 10 karat fineness, which has a minimum thickness throughout equivalent to .175 microns (approximately 7/1,000,000ths of an inch) of fine gold, may be marked or described as "Gold Electroplate" or "Gold Electroplated," or abbreviated, as, for example, "G.E.P." When the electroplating meets the minimum fineness but not the minimum thickness specified above, the marking or description may be "Gold Flashed" or "Gold Washed." When the electroplating is of the minimum fineness specified above and of a minimum thickness throughout equivalent to two and one half (2 1/2) microns (or approximately 100/1,000,000ths of an inch) of fine gold, the marking or description may be "Heavy Gold Electroplate" or "Heavy Gold Electroplated." When electroplatings qualify for the term "Gold Electroplate" (or "Gold Electroplated"), or the term "Heavy Gold Electroplate" (or "Heavy Gold Electroplated"), and have been applied by use of a particular kind of electrolytic process, the marking may be accompanied by identification of the process used, as for example, "Gold Electroplated (X Process)" or "Heavy Gold Electroplated (Y Process)."

(d) The provisions of this section relating to markings and descriptions of industry products and parts thereof are subject to the applicable tolerances of the National Stamping Act or any amendment thereof.6

Note 4 to paragraph (d): Exemptions recognized in the assay of karat gold industry products and in the assay of gold filled, gold overlay, and rolled gold plate industry products, and not to be considered in any assay for quality, are listed in the appendix.

23.5 Misuse of the word "vermeil."

(a) It is unfair or deceptive to represent, directly or by implication, that an industry product is "vermeil" if such mark or description misrepresents the product's true composition.

(b) An industry product may be described or marked as "vermeil" if it consists of a base of sterling silver coated or plated on all significant surfaces with gold, or gold alloy of not less than 10 karat fineness, that is of substantial thickness7 and a minimum thickness throughout equivalent to two and one half (2 1/2) microns (or approximately 100/1,000,000ths of an inch) of fine gold.

Note 1 to 23.5: It is unfair or deceptive to use the term "vermeil" to describe a product in which the sterling silver has been covered with a base metal (such as nickel) plated with gold unless there is a disclosure that the sterling silver is covered with a base metal that is plated with gold.

Note 2 to 23.5: Exemptions recognized in the assay of gold filled, gold overlay, and rolled gold plate industry products are listed in the appendix.

23.6 Misrepresentation as to silver content.

(a) It is unfair or deceptive to misrepresent that an industry product contains silver, or to misrepresent an industry product as having a silver content, plating, electroplating, or coating.

(b) It is unfair or deceptive to mark, describe, or otherwise represent all or part of an industry product as "silver," "solid silver," "Sterling Silver," "Sterling," or the abbreviation "Ster." unless it is at least 925/1,000ths pure silver.

(c) It is unfair or deceptive to mark, describe, or otherwise represent all or part of an industry product as "coin" or "coin silver" unless it is at least 900/1,000ths pure silver.

(d) It is unfair or deceptive to mark, describe, or otherwise represent all or part of an industry product as being plated or coated with silver unless all significant surfaces of the product or part contain a plating or coating of silver that is of substantial thickness.8

(e) The provisions of this section relating to markings and descriptions of industry products and parts thereof are subject to the applicable tolerances of the National Stamping Act or any amendment thereof.9

Note 1 to 23.6: The National Stamping Act provides that silverplated articles shall not "be stamped, branded, engraved or imprinted with the word sterling or the word coin, either alone or in conjunction with other words or marks." 15 U.S.C. 297(a).

Note 2 to 23.6: Exemptions recognized in the assay of silver industry products are listed in the appendix.

23.7 Misuse of the words "platinum," "iridium," "palladium," "ruthenium," "rhodium," and "osmium."

(a) It is unfair or deceptive to use the words "platinum," "iridium," "palladium," "ruthenium," "rhodium," and "osmium," or any abbreviation to mark or describe all or part of an industry product if such marking or description misrepresents the products true composition. The Platinum Group Metals (PGM) are Platinum, Iridium, Palladium, Ruthenium, Rhodium, and Osmium.

(b) The following are examples of markings or descriptions that may be misleading:

(1) Use of the word "Platinum" or any abbreviation, without qualification, to describe all or part of an industry product that is not composed throughout of 950 parts per thousand pure Platinum.

(2) Use of the word "Platinum" or any abbreviation accompanied by a number indicating the parts per thousand of pure Platinum contained in the product without mention of the number of parts per thousand of other PGM contained in the product, to describe all or part of an industry product that is not composed throughout of at least 850 parts per thousand pure platinum, for example,"600Plat."

(3) Use of the word "Platinum" or any abbreviation thereof, to mark or describe any product that is not composed throughout of at least 500 parts per thousand pure Platinum.

(c) The following are examples of markings and descriptions that are not considered unfair or deceptive:

(1) The following abbreviations for each of the PGM may be used for quality marks on articles: "Plat." or "Pt." for Platinum; "Irid." or "Ir." for Iridium; "Pall." or "Pd." for Palladium; "Ruth." or "Ru." for Ruthenium; "Rhod." or "Rh." for Rhodium; and "Osmi." or "Os." for Osmium.

(2) An industry product consisting of at least 950 parts per thousand pure Platinum may be marked or described as "Platinum."

(3) An industry product consisting of 850 parts per thousand pure Platinum, 900 parts per thousand pure Platinum, or 950 parts per thousand pure Platinum may be marked "Platinum," provided that the Platinum marking is preceded by a number indicating the amount in parts per thousand of pure Platinum (for industry products consisting of 950 parts per thousand pure Platinum, the marking described in 23.7(b)(2) above is also appropriate). Thus, the following markings may be used: "950Pt.," "950Plat.," "900Pt.," "900Plat.," "850Pt.," or "850Plat."

(4) An industry product consisting of at least 950 parts per thousand PGM, and of at least 500 parts per thousand pure Platinum, may be marked "Platinum," provided that the mark of each PGM constituent is preceded by a number indicating the amount in parts per thousand of each PGM, as for example, "600Pt.350Ir.," "600Plat.350Irid.," or "550Pt.350Pd.50Ir.," "550Plat.350Pall.50Irid."

Note to 23.7: Exemptions recognized in the assay of platinum industry products are listed in the Appendix.

23.8 Misrepresentation as to content of pewter.

(a) It is unfair or deceptive to mark, describe, or otherwise represent all or part of an industry product as "Pewter" or any abbreviation if such mark or description misrepresents the product's true composition.

(b) An industry product or part thereof may be described or marked as "Pewter" or any abbreviation if it consists of at least 900 parts per 1000 Grade A Tin, with the remainder composed of metals appropriate for use in pewter.

23.9 Additional guidance for the use of quality marks.

As used in these guides, the term quality mark means any letter, figure, numeral, symbol, sign, word, or term, or any combination thereof, that has been stamped, embossed, inscribed, or otherwise placed on any industry product and which indicates or suggests that any such product is composed throughout of any precious metal or any precious metal alloy or has a surface or surfaces on which there has been plated or deposited any precious metal or precious metal alloy. Included are the words "gold," "karat," "carat," "silver," "sterling," "vermeil," "platinum," "iridium," "palladium," "ruthenium," "rhodium," or "osmium," or any abbreviations thereof, whether used alone or in conjunction with the words "filled," "plated," "overlay," or "electroplated," or any abbreviations thereof. Quality markings include those in which the words or terms "gold," "karat," "silver," "vermeil," "platinum" (or platinum group metals), or their abbreviations are included, either separately or as suffixes, prefixes, or syllables.

(a) Deception as to applicability of marks.

(1) If a quality mark on an industry product is applicable to only part of the product, the part of the product to which it is applicable (or inapplicable) should be disclosed when, absent such disclosure, the location of the mark misrepresents the product or part's true composition.

(2) If a quality mark is applicable to only part of an industry product, but not another part which is of similar surface appearance, each quality mark should be closely accompanied by an identification of the part or parts to which the mark is applicable.

(b) Deception by reason of difference in the size of letters or words in a marking or markings. It is unfair or deceptive to place a quality mark on a product in which the words or letters appear in greater size than other words or letters of the mark, or when different markings placed on the product have different applications and are in different sizes, when the net impression of any such marking would be misleading as to the metallic composition of all or part of the product. (An example of improper marking would be the marking of a gold electroplated product with the word "electroplate" in small type and the word "gold" in larger type, with the result that purchasers and prospective purchasers of the product might only observe the word "gold.")

Note 1 to 23.9: Legibility of markings. If a quality mark is engraved or stamped on an industry product, or is printed on a tag or label attached to the product, the quality mark should be of sufficient size type as to be legible to persons of normal vision, should be so placed as likely to be observed by purchasers, and should be so attached as to remain thereon until consumer purchase.

Note 2 to 23.9: Disclosure of identity of manufacturers, processors, or distributors. The National Stamping Act provides that any person, firm, corporation, or association, being a manufacturer or dealer subject to section 294 of the Act, who applies or causes to be applied a quality mark, or imports any article bearing a quality mark "which indicates or purports to indicate that such article is made in whole or in part of gold or silver or of an alloy of either metal" shall apply to the article the trademark or name of such person. 15 U.S.C. 297.

23.10 Misuse of "corrosion proof," "noncorrosive," "corrosion resistant," "rust proof," "rust resistant," etc.

(a) It is unfair or deceptive to:

(1) Use the terms "corrosion proof," "noncorrosive," "rust proof," or any other term of similar meaning to describe an industry product unless all parts of the product will be immune from rust and other forms of corrosion during the life expectancy of the product; or

(2) Use the terms "corrosion resistant," "rust resistant," or any other term of similar meaning to describe an industry product unless all parts of the product are of such composition as to not be subject to material damage by corrosion or rust during the major portion of the life expectancy of the product under normal conditions of use.

(b) Among the metals that may be considered as corrosion (and rust) resistant are: Pure nickel; Gold alloys of not less than 10 Kt. fineness; and Austenitic stainless steels.

23.11 Definition and misuse of the word "diamond."

(a) A diamond is a natural mineral consisting essentially of pure carbon crystallized in the isometric system. It is found in many colors. Its hardness is 10; its specific gravity is approximately 3.52; and it has a refractive index of 2.42.

(b) It is unfair or deceptive to use the unqualified word "diamond" to describe or identify any object or product not meeting the requirements specified in the definition of diamond provided above, or which, though meeting such requirements, has not been symmetrically fashioned with at least seventeen (17) polished facets.

Note 1 to paragraph (b): It is unfair or deceptive to represent, directly or by implication, that industrial grade diamonds or other non-jewelry quality diamonds are of jewelry quality.

(c) The following are examples of descriptions that are not considered unfair or deceptive:

(1) The use of the words "rough diamond" to describe or designate uncut or unfaceted objects or products satisfying the definition of diamond provided above; or

(2) The use of the word "diamond" to describe or designate objects or products satisfying the definition of diamond but which have not been symmetrically fashioned with at least seventeen (17) polished facets when in immediate conjunction with the word "diamond" there is either a disclosure of the number of facets and shape of the diamond or the name of a type of diamond that denotes shape and that usually has less than seventeen (17) facets (e.g., "rose diamond").

Note 2 to paragraph (c): Additional guidance about imitation and laboratory-created diamond representations and misuse of words "gem," "real," "genuine," "natural," etc., are set forth in 23.23, 23.24, and 23.25.

23.12 Misuse of the words "flawless," "perfect," etc.

(a) It is unfair or deceptive to use the word "flawless" to describe any diamond that discloses flaws, cracks, inclusions, carbon spots, clouds, internal lasering, or other blemishes or imperfections of any sort when examined under a corrected magnifier at 10-power, with adequate illumination, by a person skilled in diamond grading.

(b) It is unfair or deceptive to use the word "perfect," or any representation of similar meaning, to describe any diamond unless the diamond meets the definition of "flawless" and is not of inferior color or make.

(c) It is unfair or deceptive to use the words "flawless" or "perfect" to describe a ring or other article of jewelry having a "flawless" or "perfect" principal diamond or diamonds, and supplementary stones that are not of such quality, unless there is a disclosure that the description applies only to the principal diamond or diamonds.

23.13 Disclosing existence of artificial coloring, infusing, etc.

If a diamond has been treated by artificial coloring, tinting, coating, irradiating, heating, by the use of nuclear bombardment, or by the introduction or the infusion of any foreign substance, it is unfair or deceptive not to disclose that the diamond has been treated and that the treatment is not or may not be permanent.

23.14 Misuse of the term "blue white."

It is unfair or deceptive to use the term "blue white" or any representation of similar meaning to describe any diamond that under normal, north daylight or its equivalent shows any color or any trace of any color other than blue or bluish.

23.15 Misuse of the term "properly cut," etc.

It is unfair or deceptive to use the terms "properly cut," "proper cut," "modern cut," or any representation of similar meaning to describe any diamond that is lopsided, or is so thick or so thin in depth as to detract materially from the brilliance of the stone.

Note to 23.15: Stones that are commonly called "fisheye" or "old mine" should not be described as "properly cut," "modern cut," etc.

23.16 Misuse of the words "brilliant" and "full cut."

It is unfair or deceptive to use the unqualified expressions "brilliant," "brilliant cut," or "full cut" to describe, identify, or refer to any diamond except a round diamond that has at least thirty-two (32) facets plus the table above the girdle and at least twenty-four (24) facets below.

Note to 23.16: Such terms should not be applied to single or rose-cut diamonds. They may be applied to emerald-(rectangular) cut, pear-shaped, heart-shaped, oval-shaped, and marquise-(pointed oval) cut diamonds meeting the above-stated facet requirements when, in immediate conjunction with the term used, the form of the diamond is disclosed.

23.17 Misrepresentation of weight and "total weight."

(a) It is unfair or deceptive to misrepresent the weight of a diamond.

(b) It is unfair or deceptive to use the word "point" or any abbreviation in any representation, advertising, marking, or labeling to describe the weight of a diamond, unless the weight is also stated as decimal parts of a carat (e.g., 25 points or .25 carat).

Note 1 to paragraph (b): A carat is a standard unit of weight for a diamond and is equivalent to 200 milligrams (1/5 gram). A point is one one hundredth (1/100) of a carat.

(c) If diamond weight is stated as decimal parts of a carat (e.g., .47 carat), the stated figure should be accurate to the last decimal place. If diamond weight is stated to only one decimal place (e.g., .5 carat), the stated figure should be accurate to the second decimal place (e.g., ".5 carat" could represent a diamond weight between .495-.504).

(d) If diamond weight is stated as fractional parts of a carat, a conspicuous disclosure of the fact that the diamond weight is not exact should be made in close proximity to the fractional representation and a disclosure of a reasonable range of weight for each fraction (or the weight tolerance being used) should also be made.

Note to paragraph (d): When fractional representations of diamond weight are made, as described in paragraph d of this section, in catalogs or other printed materials, the disclosure of the fact that the actual diamond weight is within a specified range should be made conspicuously on every page where a fractional representation is made. Such disclosure may refer to a chart or other detailed explanation of the actual ranges used. For example, "Diamond weights are not exact; see chart on p.X for ranges."

23.18 Definitions of various pearls.

As used in these guides, the terms set forth below have the following meanings:

(a) Pearl: A calcareous concretion consisting essentially of alternating concentric layers of carbonate of lime and organic material formed within the body of certain mollusks, the result of an abnormal secretory process caused by an irritation of the mantle of the mollusk following the intrusion of some foreign body inside the shell of the mollusk, or due to some abnormal physiological condition in the mollusk, neither of which has in any way been caused or induced by humans.

(b) Cultured Pearl: The composite product created when a nucleus (usually a sphere of calcareous mollusk shell) planted by humans inside the shell or in the mantle of a mollusk is coated with nacre by the mollusk.

(c) Imitation Pearl: A manufactured product composed of any material or materials that simulate in appearance a pearl or cultured pearl.

(d) Seed Pearl: A small pearl, as defined in (a), that measures approximately two millimeters or less.

23.19 Misuse of the word "pearl."

(b) It is unfair or deceptive to use the word "pearl" to describe, identify, or refer to a cultured pearl unless it is immediately preceded, with equal conspicuousness, by the word "cultured" or "cultivated," or by some other word or phrase of like meaning, so as to indicate definitely and clearly that the product is not a pearl.

(c) It is unfair or deceptive to use the word "pearl" to describe, identify, or refer to an imitation pearl unless it is immediately preceded, with equal conspicuousness, by the word "artificial," "imitation," or "simulated," or by some other word or phrase of like meaning, so as to indicate definitely and clearly that the product is not a pearl.

(d) It is unfair or deceptive to use the terms "faux pearl," "fashion pearl," "Mother of Pearl," or any other such term to describe or qualify an imitation pearl product unless it is immediately preceded, with equal conspicuousness, by the word "artificial," "imitation," or "simulated," or by some other word or phrase of like meaning, so as to indicate definitely and clearly that the product is not a pearl.

23.20 Misuse of terms such as "cultured pearl," "seed pearl," "Oriental pearl," "natura," "kultured," "real," "gem," "synthetic," and regional designations.

(a) It is unfair or deceptive to use the term "cultured pearl," "cultivated pearl," or any other word, term, or phrase of like meaning to describe, identify, or refer to any imitation pearl.

(b) It is unfair or deceptive to use the term "seed pearl" or any word, term, or phrase of like meaning to describe, identify, or refer to a cultured or an imitation pearl, without using the appropriate qualifying term "cultured" (e.g., "cultured seed pearl") or "simulated," "artificial," or "imitation" (e.g., "imitation seed pearl").

(c) It is unfair or deceptive to use the term "Oriental pearl" or any word, term, or phrase of like meaning to describe, identify, or refer to any industry product other than a pearl taken from a salt water mollusk and of the distinctive appearance and type of pearls obtained from mollusks inhabiting the Persian Gulf and recognized in the jewelry trade as Oriental pearls.

(d) It is unfair or deceptive to use the word "Oriental" to describe, identify, or refer to any cultured or imitation pearl.

(e) It is unfair or deceptive to use the word "natura," "natural," "natures," or any word, term, or phrase of like meaning to describe, identify, or refer to a cultured or imitation pearl. It is unfair or deceptive to use the term "organic" to describe, identify, or refer to an imitation pearl, unless the term is qualified in such a way as to make clear that the product is not a natural or cultured pearl.

(f) It is unfair or deceptive to use the term "kultured," "semi-cultured pearl," "cultured-like," "part-cultured," "pre-mature cultured pearl," or any word, term, or phrase of like meaning to describe, identify, or refer to an imitation pearl.

(g) It is unfair or deceptive to use the term "South Sea pearl" unless it describes, identifies, or refers to a pearl that is taken from a salt water mollusk of the Pacific Ocean South Sea Islands, Australia, or Southeast Asia. It is unfair or deceptive to use the term "South Sea cultured pearl" unless it describes, identifies, or refers to a cultured pearl formed in a salt water mollusk of the Pacific Ocean South Sea Islands, Australia, or Southeast Asia.

(h) It is unfair or deceptive to use the term "Biwa cultured pearl" unless it describes, identifies, or refers to cultured pearls grown in fresh water mollusks in the lakes and rivers of Japan.

(i) It is unfair or deceptive to use the word "real," "genuine," "precious," or any word, term, or phrase of like meaning to describe, identify, or refer to any imitation pearl.

(j) It is unfair or deceptive to use the word "gem" to describe, identify, or refer to a pearl or cultured pearl that does not possess the beauty, symmetry, rarity, and value necessary for qualification as a gem.

Note to paragraph (j): Use of the word "gem" with respect to cultured pearls should be avoided since few cultured pearls possess the necessary qualifications to properly be termed "gems." Imitation pearls should not be described as "gems."

(k) It is unfair or deceptive to use the word "synthetic" or similar terms to describe cultured or imitation pearls.

(l) It is unfair or deceptive to use the terms "Japanese Pearls," "Chinese Pearls," "Mallorca Pearls," or any regional designation to describe, identify, or refer to any cultured or imitation pearl, unless the term is immediately preceded, with equal conspicuousness, by the word "cultured," "artificial," "imitation," or "simulated," or by some other word or phrase of like meaning, so as to indicate definitely and clearly that the product is a cultured or imitation pearl.

23.21 Misrepresentation as to cultured pearls.

It is unfair or deceptive to misrepresent the manner in which cultured pearls are produced, the size of the nucleus artificially inserted in the mollusk and included in cultured pearls, the length of time that such products remained in the mollusk, the thickness of the nacre coating, the value and quality of cultured pearls as compared with the value and quality of pearls and imitation pearls, or any other material matter relating to the formation, structure, properties, characteristics, and qualities of cultured pearls.

23.22 Deception as to gemstones.

It is unfair or deceptive to fail to disclose that a gemstone has been treated in any manner that is not permanent or that creates special care requirements, and to fail to disclose that the treatment is not permanent, if such is the case. The following are examples of treatments that should be disclosed because they usually are not permanent or create special care requirements: coating, impregnation, irradiating, heating, use of nuclear bombardment, application of colored or colorless oil or epoxy-like resins, wax, plastic, or glass, surface diffusion, or dyeing. This disclosure may be made at the point of sale, except that disclosure should be made in any solicitation where the product can be purchased without viewing (e.g., direct mail catalogs, on-line services), and in the case of televised shopping programs, on the air. If special care requirements for a gemstone arise because the gemstone has been treated, it is recommended that the seller disclose the special care requirements to the purchaser.

23.23 Misuse of the words "ruby," "sapphire," "emerald," "topaz," "stone," "birthstone," "gemstone," etc.

(a) It is unfair or deceptive to use the unqualified words "ruby," "sapphire," "emerald," "topaz," or the name of any other precious or semi-precious stone to describe any product that is not in fact a natural stone of the type described.

(b) It is unfair or deceptive to use the word "ruby," "sapphire," "emerald," "topaz," or the name of any other precious or semi-precious stone, or the word "stone," "birthstone," "gemstone,'' or similar term to describe a laboratory-grown, laboratory-created, [manufacturer name]-created, synthetic, imitation, or simulated stone, unless such word or name is immediately preceded with equal conspicuousness by the word "laboratory-grown," "laboratory-created," "[manufacturer name]-created," "synthetic," or by the word "imitation" or "simulated," so as to disclose clearly the nature of the product and the fact it is not a natural gemstone.

Note to paragraph (b): The use of the word "faux" to describe a laboratory-created or imitation stone is not an adequate disclosure that the stone is not natural.

(c) It is unfair or deceptive to use the word "laboratory-grown," "laboratory-created," "[manufacturer name]-created," or "synthetic" with the name of any natural stone to describe any industry product unless such industry product has essentially the same optical, physical, and chemical properties as the stone named.

23.24 Misuse of the words "real," "genuine," "natural," "precious," etc.

It is unfair or deceptive to use the word "real," "genuine," "natural," "precious," "semi-precious," or similar terms to describe any industry product that is manufactured or produced artificially.

23.25 Misuse of the word "gem."

(a) It is unfair or deceptive to use the word "gem" to describe, identify, or refer to a ruby, sapphire, emerald, topaz, or other industry product that does not possess the beauty, symmetry, rarity, and value necessary for qualification as a gem.

(b) It is unfair or deceptive to use the word "gem" to describe any laboratory-created industry product unless the product meets the requirements of paragraph (a) of this section and unless such word is immediately accompanied, with equal conspicuousness, by the word "laboratory-grown," "laboratory-created," or "[manufacturer-name]-created," "synthetic," or by some other word or phrase of like meaning, so as to clearly disclose that it is not a natural gem.

Note to 23.25: In general, use of the word "gem" with respect to laboratory-created stones should be avoided since few laboratory-created stones possess the necessary qualifications to properly be termed "gems." Imitation diamonds and other imitation stones should not be described as "gems." Not all diamonds or natural stones, including those classified as precious stones, possess the necessary qualifications to be properly termed "gems."

23.26 Misuse of the words "flawless," "perfect," etc.

(a) It is unfair or deceptive to use the word "flawless" as a quality description of any gemstone that discloses blemishes, inclusions, or clarity faults of any sort when examined under a corrected magnifier at 10-power, with adequate illumination, by a person skilled in gemstone grading.

(b) It is unfair or deceptive to use the word "perfect" or any representation of similar meaning to describe any gemstone unless the gemstone meets the definition of "flawless" and is not of inferior color or make.

(c) It is unfair or deceptive to use the word "flawless," "perfect," or any representation of similar meaning to describe any imitation gemstone.
