- Chemical formula: FeS2
- Mineral group: sulfide (iron sulfide); crystal system: isometric (cubic)
- Mohs hardness: ~6.0–6.5
- Specific gravity: ≈4.9–5.2 (commonly ≈5.0)
- Transparency: opaque
- Color: brassy to pale brass‑yellow (metallic "golden")
- Streak: greenish‑black to brownish‑black
- Luster: metallic
- Cleavage: no true cleavage (may show indistinct parting)
- Fracture: uneven to sub‑conchoidal; brittle
