Three very large copper crystals, to 3 cm across, are nestled in a vug. The crystals are very lustrous with the richest and most dark chocolate colored patina on them. The base of the specimen has a crystal druse of rich blue green chrysocolla which accents the bottom - very unusual. Overall this is a very fine copper with interesting crystal habits, a very special patina, and good provenance to this classic mine.
