Item Description

A good display specimen from the famous Siglo XX mine in Bolivia featuring sharp, lustrous, black, cyclic twinned crystals of Cassiterite. Fairly common from the standpoint of species from Bolivia, but it's NOT easy to find well crystallized pieces of Cassiterite from this mine as opposed to places like Viloco or Huanuni. The largest twin measures 1.3 cm across.
