Emerald Cut Sapphire Diamond in Ring in Platinum.  This modern cocktail ring features a 2.80 carat emerald cut sapphire with .45 carats of round accent diamonds and is set in platinum. The shank is quite thick and splits and comes back together twice, creating a strong look with nice negative space. The design shows a lot of metal with neat notches taken out of the sides where the accent diamonds are set and the ring is quite heavy at 10.6 grams. These details come together and make this a fabulously robust cocktail ring.
