Mammoth Mine, Gunpowder District, Queensland, Australia
Size Range: 
Thumbnail (1-3cm)

2.5 × 1.6 × 1 cm
Description

This thumbnail is solid chalcocite and is composed of several intergrown terminated crystals, the largest being 1.5cm long. Some faces show striations. Some minor green vertigo adds some colour and interest.

These crystals were foung several years ago and as is often the case, nothing noteable seems to have surfaced since. The crystals have a good grey metallic lustre and these are now very difficult to obtain.
