Though dark, it is transparent facet grade throughout with a more greenish brown at the upper third and a bright pure green in the lower two thirds. There is a bit of edge chipping along the sides, it's complete all around, and has a perfect termination. Weighs a hefty 153 grams.

ST445 - Pyrite $ 2000 SOLD Merelani Hills, Arush Region, Tanzania small cabinet - 8.5 x 7.5 x 6 cm ![]() ![]() ![]() ![]() Large, complex, and COMPLETE single Pyrite crystal from the Merelani Tanzanite mines. Merelani produces a number of 'world's best' species, and when these Pyrites started coming out recently, an argument could be made that Pyrite from Merelani is also among the world's best for species. The large size, golden color, complex form combined with high luster make them spectacular. However most have dings and are contacted on the back side where they grew against Graphite. This one is exceptional as it is fully crystallized all around and nearly pristine. There is a small indentation on the lower backside where it attached to a mixture of Calcite and Graphite, but even the inside of the indentation is crystallized. There were hundreds to thousands of these found, but very few were this size, and of those I've never seen one this perfect. If you were waiting for the right one, this might be it. ©2010-2018 Marin Mineral |
