Named for the cauldron-like center of a volcano. This ring holds a center brilliant cut white diamond nearly a quarter carat in size. The fine open bezel holds the diamond at just the right angle allowing as much light as possible to refract through each facet. The open galley and sloped setting set with an additional 10 accent brilliant cuts add lustre and depth. Total carat weight 0.35. Available in 14K yellow, rose or white gold. Size 5-9.
