Physical Properties:
Color is copper colored with weathered specimens tarnished green.
Luster is metallic.
Transparency is opaque.
Crystal System is isometric; 4/m bar 3 2/m
Crystal Habits include massive, wires and arborescent or branching forms as the most common, whole individual crystals are extremely rare but when present are usually cubes and octahedrons. Occasionally, massive forms will show some recognizable crystal faces on outer surfaces.
Cleavage is absent.
Fracture is jagged.
Streak is reddish copper color.
Hardness is 2.5-3
Specific Gravity is 8.9+ (above average for metallic)
Associated Minerals are silver, calcite, malachite and other secondary copper minerals.
Other Characteristics: ductile, malleable and sectile, meaning it can be pounded into other shapes, stretched into a wire and cut into slices.
Notable Occurrences include Michigan and Arizona, USA; Germany; Russia and Australia.
Best Field Indicators are color, ductility and crystal habit.
