Copper (leaf-like specimen)

Specimen # BOL711B245

the miner in Bolivia who found the specimens was referring to them as “dientes” (Spanish for teeth)

had a stake in this mine in the late 1970’s / early 1980’s and was able to acquire some superb and interesting specimens

The beetles look like they're marching almost like ants

This was one of the very few multi-twinned pieces from the find of these amazing specimens in June of 2010

well-crystallized terminated

The Viloco Mine (sometimes called Araca) for many years has stood as one of the top Cassiterite localities in the world

If you’re a Bolivian collector

so much so that we decided to draw a red “X” on one of the photos to help illustrate the twinning planes

The concentration of decent-sized crystals on this piece makes this a worthwhile cabinet sized piece of this classic material

medium luster

or incomplete (broken) spheres on matrix
