- Chemical formula: C (pure carbon)
- Mineral group: Native element (carbon)
- Color: typically colorless to various colors (can be white/near-colorless, yellow, brown, blue, pink, green, etc.)
- Streak: colorless/white (streak test is impractical because diamond is harder than a streak plate)
- Hardness: 10 on the Mohs scale (hardest natural mineral)
- Luster: adamantine (very brilliant)
- Specific gravity: ≈3.51–3.53 (commonly given as ~3.52)
- Cleavage: perfect in four directions on {111} planes (octahedral cleavage)
- Transparency: transparent to translucent (gem-quality stones are transparent)
- Fracture: conchoidal to uneven (when broken not along cleavage planes)
- Mineral group: Native element (carbon)
- Color: typically colorless to various colors (can be white/near-colorless, yellow, brown, blue, pink, green, etc.)
