This entry records colour: Copper-red, tarnishes to brown/green; lustre: Metallic; streak: Copper-red; Mohs hardness: 2.5-3; cleavage: None; crystal system: Isometric Cubic; transparency: Opaque. Confirm an important identification with additional field tests or qualified laboratory work.

How does Copper native form?

Forms in the oxidized zone of copper deposits and in basaltic lava flows Lake Superior type .

Where is Copper native commonly found?

Michigan USA , Chile, Namibia, Russia; found in basaltic lavas and oxidized copper deposits.

What is Copper native commonly confused with?

Copper native may be confused with Chalcopyrite, Bronze artifacts, Bornite. Compare multiple diagnostic properties because colour and surface appearance can overlap.
