{"product_id":"mottramite-8","title":"MOTTRAMITE","description":"When it comes to impressive crystallized Mottramite - lead copper vanadate - you can't get much better than this magnificent textural piece from Tsumeb mine. It come from the generations-old Weyand collection in Tsumeb, Namibia and is entirely crystallized Mottramite. For what is ordinarily a very rare species the quality of this piece is light years ahead of anything seen elsewhere in the world. This magnificent cabinet-sized display specimen shows you how amazing this species is. Forming a heavy dense aggregate of pure Mottramite, it is not only this richness in volume, but its superb external visual properties which make it so wonderful. Underneath, the Mottramite forms florette-like growths rising up to a satiny glossy botryoidal outer surface. The whole is an intensely dark green colour to almost black but it is its shimmering velvet-like lustre that really catches the eye. In exceptional condition this is a world-class Mottramite and was probably mined in the first half of the 20th century.
