A.    When an auction sale under this chapter relates to jewelry, it is unlawful for any person so licensed to offer for sale by auction any article to which there is not attached a card or ticket or label containing a true and correct statement, plainly written or printed in English, specifying the kind and quality of the metal of which such article is made or composed, or the percentage of karat or purity of such metal. If such articles are plated or overlaid, then such tag or label shall contain a true statement of the kind of plate.

    B.    When precious stones are for sale or sold by auction as such or as part of an article of jewelry, such written statement shall set forth the true name, weight and quality of such stones.

    C.    When semiprecious stones are offered for sale or sold by auction as such or as part of an article of jewelry, such written statement shall set forth the true names of such stones.

    D.    When imitations of precious or semiprecious stones are offered for sale or sold by auction as such or as part of an article of jewelry, such imitations shall be described or defined as synthetic or imitations of such stones as they purport to represent.

    E.    When watches and clocks are sold the true names of the manufacturers shall be stated in writing and no parts of the movements or mechanism of them shall be substituted or contain false and misleading names of trade marks; neither shall secondhand or old movements be offered for sale in new cases without a true statement to that effect. Used and rebuilt watches should be so indicated.

    F.    Such tag or label shall remain securely attached to any such article or merchandise, shall be delivered to the purchaser as a true and correct description and representation of the article sold and shall be deemed prima facie evidence of intent to defraud in case such written statement is not a true and correct description and representation of such articles sold. (Prior code § 3-12)
