Description

Very nice calcite specimen with phantom crystals. Only one with a broken tip. Otherwise very fine with good luster. I spotted a metallic gray tenorite crystal/shard between the calcite scalenohedrons (too small to photograph). Maybe that's also the material responsible for the 'dirty' color? But some of the inclusions look almost biogenic. Very interesting under the microscope.
