Art Deco 1.00 Carat Diamond Onyx Platinum Ring
Brought to you in glorious black & white during the early-Art Deco period - circa 1920, this dramatic Jazz Age jewel glistens in the center with an usual stone: a 1.00 carat old mine-cut diamond imbued by Mother Nature with a light brown glow. The intriguing stone is dramatically presented in the center of a square glossy black onyx plaque enhanced all around by a beveled diamond-set frame. Diamond-set shoulders, delicate milgraining, and a fanciful open navette motif under gallery add the finishing flourishes to this chic, sophisticated, and stunning Jazz Age jewel. 9/16 inch square. Currently ring size 8 3/4.
