This is a very robust, large, exceptional example of the species, way beyond the norm in size and sharpness. The crystal is complete all around, and seems to be twinned. We have all seen a huge number of small kesterites, often clustered like grapes on matrix, but isolated large crystals such as this are very uncommonly mined. This single locality has produced the world's best of this rare species by several orders of magnitude.
