Natural Modified Cubic Native Silver Crystals on Crystallized Calcite 
Bouismas Mine, Bou Azzer mining district, Drâa-Tafilalet Region, Morocco
 
Native Silver from Morocco has never been seen with such outstanding habits of modified cubic crystals spread thorough the crystallized calcite matrix. The crystallization has developed in a variety of hoppered octahedron and trigon crystals with also long thick wired formations as well. Crystallized native silver specimens like this example are becoming very difficult to collect as the quality of the specimens are diminishing. This prime specimen was part of an older find which was discovered in 2014 when silver discoveries were still fairly new in Morocco.
