SONORA / Milpillas Mine (Volborthite)

Volborthite with Malachite
 

EV67AC1: Volborthite was the new sensation in the Tucson Show 2015 as well as in Ste. Marie, but the number of them seems to be somewhat limited.
The Milpillas ones are without doubt the world's best for their luster, shape, good contrast with the white clay matrix and the crystal size of the best ones, so all together these are a new standard for this species. We are proud to offer this one which has a very reasonable balance quality / price.

XM145TC: Groups of Volborthite crystals with two different morphologies: acicular and flattened. The very lustrous and deep olive-green crystals sit on a Dickite matrix. Milpillas Volborthite specimens are considered the best of the species due to their quality, luster and crystal size, and set a new standard for the species.
