Calcite with Boulangerite inclusions

This fine specimen consists of 6 large spheres, and one small sphere of Calcite. The Calcites are tinted black due to the inclusion of Boulangerite. This piece is very bright and sparkly (often these have a dull luster).

All the mines in Romania are currently closed. They've had a bad history of environmental problems among others. Finding good examples like this one are becoming few and far between.

No Damage.
