GIA Certified 12.23 Carat Unheated Blue Sapphire and Diamond Platinum Ring


Gorgeous Royal Blue Sapphire (12.23cts) is set in platinum with 2 half-moon shaped Diamonds that weigh a total of 1.50cts. These diamonds are fine quality VVS2 clarity and D-E color.

This gem is beautiful in all aspects and is not cut deep, enabling the ring to sit low on the finger.
