A large thumbnail specimen of excellent lustrous metallic black Wurtzite crystals embedded in a drusy matrix of lenticular colour-zoned Siderite crystals. Well crystallised Wurtzite is seldom seen, but this from its type locality in the San José mine, Oruro City in Bolivia is exceptional. The specimen is spot glued to a clear acrylic base.
