|Dimensions||7.8 × 9.0 × 2.2 cm|
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.
