Here is a rare, gem topaz with blue zoning in the center of the crystal from Jos Plateau, Plateau State, Nigeria. The crystal developed as a floater and crystallized all over with the exception of a couple small rough spots. A nice piece with no reserve. This material normally sells for around $1.50 per gram, so this is a great opportunity to get this at an unbeatable price well below market value! The dimensions are 4 by 2.7 by 1.85 cm and weighs 55.6 grams, or 278 carats. I also h...ave many other items up for auction as well starting as low as $0.01! I can offer combined shipping with any other pieces to save money on the total shipping cost.
