About Blistered CopperHide

Formula:
CuFeS2
Colour:
Brassy
Lustre:
Metallic
Name:
In allusion to the blistered-appearing botryoidal structure, and perhaps for its visual similarlity to the "blister copper" from smelting.
A botryoidal variety of chalcopyrite.

Very often referred by collectors as "Blister Copper", but this name also refers to a partly purified copper with a blistered surface formed during smelting ( see Blister copper (smelted)).
