Beskrivning:
Zoisite (Var.: Tanzanite)
- Locality: Merelani Hills (Mererani), Lelatema Mts, Arusha Region, Tanzania (Locality at mindat.org)
- Size: 2.4 x 1.7 x 0.8 cm.
- Rare, bi-colored tanzanites were prominently featured in the recent Merelani Hills article in the Mineralogical Record. This striking gem crystal has an interesting, double termination above the pastel yellow-green, base. The upper portion of the crystal displays the classic, 3-way pleochroism found in many zoisites: the A-axis faces are a pleasing purple; the B-axis faces are light blue; and the vertical C-axis show shades of red, even with the yellow-green base. This is a much in demand, highly representative rarity.
