Cassiterite

Item Description

Bolivia has probably produced more tin than any other country in the world. The great tin mines at Viloco (sometimes called Araca) have produced some of the most magnificent Cassiterite specimens extant. This particular specimen hosts several fine quality, sharp, rather lustrous, cyclic twinned crystals ranging from dark brown to black in color with minor Quartz. This piece is in great shape overall. This classic material from Viloco is simply not seen for sale in today's market very often.
