AF763 - Tanzanite $ 4500 Merelani Hills, Lelatema Mtns., Arusha Region, Tanzania thumbnail - 3.1 x 1.8 x 0.8 cm Glassy bi-color crystal, blue base with a yellow termination. This crystal has superb luster and unusually uniform shape, retaining an even 8mm thickness all the way from the base to the termination. The yellow zone is facet grade and the blue zone, while having some internal fractures, is still mostly transparent - you can read through most of the crystal. Just a few tiny, trivial nicks otherwise totally undamaged. This is one of, if not the best of these yellow/blue bi-color crystals I have ever seen. ©2010-2018 Marin Mineral |
