Vivid green Tremolite crystal from the Merelani Tanzanite mines. Complete all around and well terminatedd (most are unterminated shards). Like many other minerals from Merelani, the Tremolite found here is considered the best in the world. Glassy and undamaged.

Excellent example of Cuprite crystal altering to Malachite from Chessy, the very best of a small lot I reviewed that had recently been relased for sale. Complete single crystal with great form and smooth surface luster. Undamaged. Old, classic specimen possibly from the 1800s.
