- Color is lead to silver gray sometimes with a bluish tint.
- Luster is metallic to dull in weathered faces.
- Transparency crystals are opaque.
- Crystal System is isometric; 4/m bar 3 2/m
- Crystal Habits include the cube, octahedron and combinations of the two. Spinel twinning is possible forming flattened crystals. Also massive and granular.
- Cleavage is perfect in four direction forming cubes.
- Fracture is uneven and rarely seen because of the perfect cleavage.
- Hardness is 2.5+
- Specific Gravity is approximately 7.5+ (heavy even for metallic minerals)
- Streak is lead gray
- Associated Minerals are calcite, dolomite, sphalerite, pyrite and other sulfide minerals, also lead oxidation minerals such as cerussite and anglesite.
- Other Characteristics: brighter metallic luster on cleavage surfaces than on crystal faces.
- Notable Occurances include Texas-Oklahoma-Missouri area, USA; Germany, Peru, Mexico, Zambia, and England.
- Best Field Indicators are crystal habit, cleavage and, perhaps most importantly, density.
