Cassiterite

Item Description

This piece shows why the great tin mines at Viloco have produced some of the most magnificent cassiterite specimens in the world. This particular specimen consists of many superb, sharp, highly lustrous, cyclic twinned, gemmy brown xtals with minor quartz underneath. This very attractive piece has no damage on the display face and is one of the better ones for gemminess that I have seen from the locality recently. This classic material from Viloco is simply not seen for sale in today's market and it is the ONLY Bolivian locality to produce facet grade cassiterite.
