TUC115-236 - Tanzanite - $ 18000 Merelani Mines, Lelatema Mts, Arusha Region, Tanzania miniature, 3.7 x 2.9 x 2.5 cm - Few tanzanites show as much mixing of colors as this crystal does. By this , I refer to the fact that natural tanzanite is trichroic, viewed as blue or purple or red down each of the three axes of display. However, most tanzanites show discrete color, in which you must rotate the crystal a full 90 degrees to see the next color in line. Joe Budd Photos…
