Dioptase crystals floater group

Amazing floater group of dioptase crystals from Congo.

Dioptase is one of the more sought after minerals for serious collector.

Its bright green colour gives it a first line place in any showcase. For that reason is also one of the more expensive minerals.

Despite that, pristine specimens are quite rare due to poor excavation techniques.

This small thumbnail specimen is unusual for lack matrix and represents a top quality for colour and shape.
