This ring features a parti-Sapphire that looks so much better in person. The photos are not a good representation of the sapphire. The sapphire is dark blue on one side and green on the other. It weighs 2.13 carats and is 9.1 by 7.25 millimeters. The ring is made from 18k yellow gold and Platinum. The stone sits on an angle when worn on the finger. It is size 6 3/4. There is a video of the ring on our Instagram page.
