Lovely Art Deco pools of light necklace circa 1920 or 1930, made from 19 genuine rock crystal orbs, undrilled, held in silverplate wire, with a spring ring clasp and connecting jump rings. The clasp is marked but illegibly except for the number 211 in a cartouche. The metal is dark brass or other goldtone base metal with traces of silver or white gold plating, however most of the plating is lost. Guaranteed genuine rock crystal; images viewed through the orbs are shown upside down and backwards...
