Description

During the last days of mining operations at the Gunpowder mine, a single pocket of sharp bladed chalcoite crystals was found and saved.

This is one the best and largest specimens from that find and unlike most is free of any obvious damage.

The crystals have a metallic blue patina and form a beautifully balanced rosette.

The largest crystal in this group measures 2.2cm across and is surrounded by crystals that nearly as large.
