The mine at Huanuni is one of the largest tin mines in Bolivia. This mine is better known for its phosphate species, but some of the more unique and attractive Cassiterite specimens are found there. A few sharp, lustrous, black/brown, prismatic "drill-bit"-habit crystal groups of Cassiterite sit atop frosted, white, prismatic "scepter" Quartz crystals. This "drill-bit"-habit is rarely seen in Cassiterite and the best Bolivian specimens of this habit are found at Huanuni. This piece came out of the ground about 25 years ago. Ex.
