Raw Aquamarine Diamond Silver Ring, Frozen Island - This gemstone looks like an island encased in ice. We've built a rough bezel around the aquamarine and sculpted a rustic band to match. Down one side of the band we've set tiny accent diamonds in delicate prongs. Aquamarine is rough and unfaceted, weighing 3.7cts. The ring is made from sterling silver and is one of a kind.
