Art Deco .55 Carat Diamond Engagement Ring by Katz and Ogush
Highly regarded by in-the-know professionals, the 'Certified' mark, an imprint of New York jewelry manufacturers Katz & Ogush, signifies some of the finest jewels of the 1920s-30s, and this distinctive Art Deco dazzler is no exception. A bright-white and sparkling European-cut diamond, weighing .55 carat, scintillates from within a platinum bezel between streaks of scissor-cut calibre sapphires leading to classic stirrup motif shoulders. A half dozen tiny single-cut diamonds add a little extra glint to this singular vintage stunner. Currently ring size 6 1/4.
