Pyrite is an iron sulfide famous for its metallic brass-yellow color, sharp cubes, pyritohedrons, and the nickname fool’s gold. It is one of the most recognizable sulfide minerals and occurs in many geological environments around the world.
Quick Facts
- Formula: FeS₂
- Crystal system: Isometric (cubic)
- Mohs hardness: About 6–6.5
- Color: Pale brass-yellow
- Streak: Greenish-black
- Luster: Metallic
- Relationship: Dimorph of marcasite
History & Name
The name Pyrite comes from the Greek word for fire, referring to the sparks that can be produced when it is struck against harder material or metal. Its gold-like color has caused confusion with native gold for centuries, but Pyrite is harder, more brittle, and has a dark streak.
Metaphysical Meaning
Modern crystal traditions commonly associate Pyrite with confidence, protection, ambition, practical action, prosperity, and maintaining strong personal boundaries. These are spiritual and symbolic traditions rather than scientifically established effects.
Common Intentions
- Confidence in business or financial planning
- Taking practical action toward a goal
- Protection and strong boundaries
- Motivation and persistence
- Prosperity and abundance-focused work
Care & Handling
Keep Pyrite reasonably dry. Some specimens can oxidize in humid conditions, producing deterioration sometimes called pyrite decay. Avoid long soaking, acids, bleach, and harsh chemical cleaners. Dust gently with a dry soft brush or cloth and store valuable specimens in a stable, low-humidity environment. Do not combine reactive or deteriorating Pyrite specimens with delicate neighboring minerals in enclosed storage.
