Description

Stibnite/calcite specimens from China are not uncommon but specimens of this size and quality are very rare. The calcite crystal is 6.5 cm in length, sharp and with a yellow colour. The transparency is such that stibnite crystals attached to one side of the calcite can be seen from the other. The calcite crystal was difficult to photograph and is much better  in person. 

A skirt of stibnite crystals surround the calcite and many others are attached to and included within it.

An impressive specimen that displays well from all sides.
