Lady's 18K White Gold Sapphire & Diamond Ring. Ring Size: 7.5 (Can be Resized to Fit Most Any Finger.) Contains: Three Natural Oval Cabochon Sapphires. Weight Approx: 7.50cttw, Color: Blue, Origin: Thailand. Forty-Four Natural Round Brilliant Cut Diamonds. Weight Approx: 1.00cttw, Color: G-H, Clarity: VS / SI. This is a fine and unusual 3-stone sapphire cabochon and diamond ring. The three stones are mounted in a custom made 18k white gold mounting, and accented by 44 white and bright diamonds, all perfectly matched. It is a great ring for business or pleasure. As I mentioned before, sapphire is a very durable gem, harder and tougher then most diamonds. At our price, you bought a rare ring you can't find anywhere else. I have been looking for a long time for this configuration and this is the first I have seen.
