Copper

Very showy larger specimen from Bou Baker, Oriental Region, Morocco. Matrix face is covered with pink dolomite crystals. Gypsum balls containing lime green devilline are scattered across the dolomite.

Spectacular grouping of sky blue crystals Celestine crystals. Individual crystals measure up to 3.0 cm in length. There is no damage on the display face of this specimen. This specimen comes from Sylvania, Ohio.

Beautiful transparent blue to mauve color cubes up 2.0 cm on edge. Crystal edges are bevelled, (I believe the modified cubes are correctly described as tetra hexahedrons). Scattered pyrite is visible in the crevices around the perimeter of the specimen. The specimen is from the Jamina Mine, Corrales, Berbes – Caravia, Austurias, Spain.

Undamaged grouping of tan colored calcite crystals projecting prominently from a matrix which is covered with a first generation of smaller white calcite crystals. The top crystal is twinned. An unusual locality for me in that it comes from Gralex Quarry, Mont-sur-Marchienne, Charleroi, Hainaut Province, Belgium.

Very attractive group of well crystallized copper with a black tenorite patina coating. This specimen is from the Cliff Mine, Keweenaw County, Michigan.
