This calcite on a quartz Cluster bed is pretty with clear and smokey quartz crystal points.  This time, we picked one that's a little different from the rest. This piece has that denser calcite speckled on it, which adds a bunch of character. 
Scottish quartz is abundant but not abundantly beautiful. This piece is an incredible quartz cluster with both large and small crystals. It has a smokiness to it that comes from other minerals in the soil. This Scottish quartz crystal also has a patch of calcite crystals.
