Description

The main crystal is 20 mm across, it is multiple stepped, all edges and faces are razor sharp terminated and each of them is highly lustrous. The colour is as good as it ever could be and the sample with this exposed main crystal is very asthetic. Really a mayor peace for this classic locality.
