Description

Beautiful specimen with well-formed white rhombohedral single crystals scattered in more areas of the specimen together with prismatic hexagonal (twinned) willemite and a few long pointed cerussite crystals. This specimen comes from the Su Elzu mine, a now "defunct" location which in the last decades of the past century produced samples, almost certainly among the best in the world, of the rare cadmium carbonate, otavite.
