Art Deco Onyx And Diamond Necklace
ABOUT THIS NECKLACE
Striking, to say the least, this beveled pentagonal plaque of glossy black onyx has a bright pop of sparkle at its center courtesy of a bezel-set .25 carat European-cut diamond. Two rows of rose-cut diamonds (that swivel back and forth) add shimmer to the top of this dramatic assemblage which connects to an 18-inch platinum chain (total length is 18 3/4 inches including the width of the pendant). Total diamond weight, .45 carat. Hand fabricated in platinum, circa 1920.
