Mottramite with Chervetite - Sold

Mottramite is a copper lead vanadate mineral. Roscoe (1876) named this mineral after Mottram St. Andrew, Cheshire, where an ore pile supplied the original material. Chervetite is a much rarer mineral, specifically lead pyrovanadate. Bariand et al. (1963) named the mineral after Jean Chervet (1904-1962), French mineralogist.

This specimen is a piece of sandstone with a fracture surface covered in fine yellow-orange francevillite, mostly covered by blocky mottramite crystals to 1 mm, and scattered chervetite prisms to 2 mm. The unusual feature of this specimen is the crystallization of the mottramite, a mineral characterized by its globular textures. Interesting and unusual specimen!
