(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 (h): 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.
