This is really beautiful, lively blue zircon in a 6x4mm mixed cut oval. Blue zircon is renowned for its very strong brilliance and fire and this material is no exception. It's the strong double refraction that causes this and you can see the eye-visible doubling in the photographs. The colour is a very nice strongly greenish blue. Nice and clean as well, with a good polish and finish. Zircon has a high specific gravity, which translates into a relatively high carat weight for the size of stone.
