Description

First I have to note, that the camera was not able to capture the fantastic quality of both minerals. The calcite shows incrdible good luster, really sparkling! The spheres consist of numerous tiny faces, all sharp and luster is perfect all around. The contrast to jet-black razor sharp terminated sphalerite crystals is fantastic, also sphalerite shows perfect luster and the calcite group is completely exposed. A really very aesthetic combination in finest quality.
