- Chemical formula: C (carbon)
- Mineral group: Native element (carbon group); polymorph of carbon (graphite)
- Color: Steel-gray to black
- Streak: Black to dark gray
- Hardness (Mohs): ~1–2
- Luster: Metallic to submetallic (can be earthy on massive material)
- Specific gravity: ~2.09–2.23 (commonly ≈2.20)
- Cleavage: Perfect basal cleavage {0001} (one direction; sheets)
- Transparency: Opaque (but thin flakes may be translucent)
- Fracture/tenacity: Uneven to flaky; sectile/flexible (can be cut with a knife and forms flexible, scaly flakes)
