Description

An excellent sample of sanromanite, a rare sodium-calcium-lead-carbonate, from the Type Locality. The specimen has a very rich coverage of highly lustrous colourless sanromanite crystals on a matrix of ultramarine blue to purple lath-like crystals of the rare sodium-copper-carbonate juangodoyite (pseudomorphs after chalconatronite). Beautiful under magnification. From my own collection.
