The piece consists of lustrous, chocolate brown, crystallized "casts" after an unknown mineral which are associated with bright silvery Galena crystals on matrix. These specimens came out around 2002, and I only saw a few of them. I was never able to obtain an accurate locality, ... |

Siglo Veinte Mine (Siglo XX Mine; Llallagua Mine; Catavi), Llallagua, Rafael Bustillo Province, Potosí Department, Bolivia A very rare species, scarcely appearing in esthetic pieces. In this case there is a complete rosette of bicolored crystals of Wurtzite (some of them bright black and some other brown) and so well positioned on the Quartz matrix that it results in an attractive specimen. The group is completed by a curious Fluorapatite crystal, tabular and ... |
