Art Deco 3.18 Carat Colombian Emerald and Diamond Platinum Ring - GIA
A gorgeous deep green Colombian emerald, weighing 3.18 carats (but presenting significantly larger due to its artful cutting), fashioned with a classic square octagonal outline, glistens and glows from within this consummate original Art Deco finger-hugger hand fabricated in platinum - circa 1925. The striking gemstone is beautifully presented in classic architectural geometric Art Deco glory between a pair of straight baguette diamonds and numerous small single-cut diamonds. A scroll work under gallery supports this magnificent Jazz Age jewel. Accompanied by a GIA Gemological Report stating: F2 - Moderate Treatments, Colombian origin. Currently ring size 7 1/2.
