This cabinet-sized piece features numerous black, lustrous, sharp Cassiterite crystals on a matrix of clear, microcrystalline Quartz from the famous Viloco Mine in Bolivia. The Cassiterite crystals are exceptionally large, very sharp and mirror-like and contrast nicely with the microcrystalline Quartz. The crystal edges reveal an unexpected golden-brown translucency. A very aesthetic piece with great color, luster and crystal formation. In excellent condition.

Location: Viloco Mine, Loayza Province, La Paz Department, Bolivia
