Mottramite pseudo with Calcite (Tsumeb)
Tsumeb Mine, Namibia. 30mm x 15mm x 15mm.
This unusual little specimen consists of Mottramite replacements after what could have been Mimetite but thats a guess. The little hollow "pipes" are all mottramite included while the surface has been coated with small calcites as well as the larger calcite at the end. It's unique and quite special indeed. packed shipping weight +/- 80gr.
