NWOT, Natural Tanzanite and natural white Zircon earrings. These are done in a marquis cut with a Halo of natural white Zircon surrounding the beautiful deep purple/blue Tanzanite. Earrings measure 1/2 inch by 1/4 inch. The center stone measures approx 10x5mm. Total carat weight is approx 2cts, but I would say that they are over. The color on these stones is amazing. Metal is 925 Sterling Silver.
