Pyrite

Main Elements:

Fe, S

Chemical Composition:

FeS₂ (Iron Sulfide)

Density:

5.0-5.1 g/cm³

Compressive Strength:

Variable

Melting Point:

Decomposes

Formation:

Forms in a variety of environments: sedimentary deposits, hydrothermal veins, and as a replacement mineral. Often forms perfect cubic crystals.

Composition:

Composed of iron sulfide (FeS₂), making it the most common sulfide mineral.

Types:

• Cubic Pyrite
• Pyritohedron Pyrite
• Marcasite (polymorph)

Etymology:

Derived from the Greek word "pyr" meaning "fire", because pyrite produces sparks when struck with steel.

Uses:

• Sulfur source
• Collector specimens
• Jewelry (faceted)
• Decorative items

Distribution:

Found worldwide, especially Spain, Peru, United States, and Italy

Historical Use:

Used for thousands of years. Ancient peoples used pyrite to start fires. It was once used to make sulfuric acid.

Symbolism:

Represents protection, wealth, and energy. Known as "Fool's Gold" due to its gold-like appearance.

Why is pyrite called "Fool's Gold"?

Pyrite is called "Fool's Gold" because it has a gold-like appearance, but it's much harder than gold and has no real gold value.

Is pyrite dangerous?

Pyrite can produce sulfuric acid when exposed to moisture, which can damage other minerals and be harmful. Some pyrite may contain arsenic. Handle with care.

What is pyrite used for?

Pyrite is used as a sulfur source, in collector specimens, jewelry (when faceted), and decorative items. It was historically used to start fires.
