Description

This is the best cobaltan calcite specimen I have come across for some time. The crystals are up to 1.2 cm long and are very lustrous and of excellent colour. Much of the material from this location has the crystals highly inter-grown however in this specimen there is a good degree fo separation. Beautiful example.
