Tanzanite Sapphire Silver Ring, Miami Blue - Sweeping curves of silver hold a scattering of white sapphires. They are graduated in size to fit the taper of the pendant and weigh 0.25ct total. Scintillating tanzanite, however, is the main focus in this ring. It is offset in the asymmetrical design, and tucked securely into the ring design. As blue as the ocean on a cloudy day, this lab created tanzanite weighs one carat, round brilliant shape. Squared corners top and bottom complete the avant garde look, and the square bottom corners will keep the piece upright on your hand. This piece is sterling silver and finished to a high polish.
