Largest crystal size: 45mm mm
This specimen is not available for sale.

A very strange aggregate of elongated crystals or skeletal crystals of copper that have formed in an open vein, associated with greenish, granular epidote. Each of the "crystals" appears like a ribbon, spanning the depth of the vein in parallel growth wit the others. Unusual!
