Jewelry, whether made from gold and precious gems or plastic and colored glass, is popular with collectors. Values are determined by the intrinsic value of the stones and metal and by the skill of the craftsmen and designers. Victorian and older jewelry have been collected since the 1950s. More recent interests are Art Deco and Edwardian styles, Mexican and Danish silver jewelry, and beads of all kinds. Copies of almost all styles are being made. Costume jewelry makers are copying antique rings and pins in inexpensive versions and prestige jewelry stores are selling gold replicas of nineteenth-century jewelry. American Indian jewelry is listed in the Indian category. Tiffany jewelry is listed here.
