Huge Tanzanite Crystal, Natural Unheated Specimen From Tanzania, 94 Grams: $15000.00
Huge Tanzanite Crystal, Natural Unheated Specimen From Tanzania, 94 Grams.
Zoisite var. Tanzanite Merelani Hills, Lelatema Mountains, Simanjiro District, Manyara Region, Tanzania 8.1 x 2.7 x 2.1 cm (3.18 × 1.06 x 0.83 in) Weighing in at 94 grams and a tall 8.1 centimeters, this single Tanzanite crystal is huge, with an excellent presence and simple beauty. Even at this size, the quality of the form is still exceptional: the termination is complex, with facet-like faces, and the backside of the specimen has a reflective and unique etching, even featuring a small cavity that dives into the prism of the crystal. The classic Tanzanite Blue comes from natural heating from underground, similar to the natural radiation that colors smoky Quartz. The difference between naturally-colored Tanzanite and artificially heated Tanzanite is the pleochroism, particularly the appearance (or lack thereof) green on the A axis when viewed horizontally; this specimen does show this green color when rotated before a polarized light. In addition to this green, the specimen has a violet color through the B axis, and under typical display conditions and especially with some backlighting) the primary color is a deep indigo blue. This is the signature color of Tanzanite, made famous through both fine gemstones and excellent crystals such as this.
