Mineral Species Information – What is Pyrite?

Pyrite is one of the most recognisable and widely collected sulfide minerals, scientifically classified as:

• Mineral Name: Pyrite

• Chemical Formula: FeS₂ (Iron Sulfide)

• Mineral Group: Sulfides

• Crystal System: Isometric (Cubic)

• Hardness: 6–6.5 on the Mohs scale

• Lustre: Metallic

• Transparency: Opaque

• Typical Colour: Pale brass-yellow with a bright reflective sheen

Often nicknamed “Fool’s Gold” due to its golden appearance, pyrite is valued for its natural geometry, metallic brilliance, and frequent occurrence in striking crystal forms.

Geological Formation & Madagascar Locality

Pyrite forms in a wide range of geological environments, making it an important mineral for understanding ore formation and Earth processes. In Madagascar, pyrite is commonly found within:

• Hydrothermal mineral veins

• Metamorphic rock zones

• Sedimentary deposits rich in sulfur and iron

Madagascar is internationally known for producing high-quality mineral specimens, including sulfides, quartz varieties, and rare gemstones. Pyrite from this region often forms under hydrothermal conditions, where hot mineral-rich fluids circulate through fractures in rock. As these fluids cool, iron and sulfur combine to crystallise into pyrite.

Associated minerals in similar environments may include:

• Quartz

• Calcite

• Fluorite

• Galena

• Chalcopyrite

These geological settings create excellent conditions for well-developed pyrite clusters and crystal groupings.

Crystal Shapes, Surface Features & Natural Character

Pyrite is famous for its distinctive crystal habits, which may include:

• Cubes with sharp edges

• Pyritohedrons (12-sided forms)

• Massive or granular aggregates

• Clustered crystal growth on matrix

Specimens may show natural striations on crystal faces, a hallmark feature of pyrite’s cubic structure. Some pieces may have slight natural oxidation tones or surface variation, which is normal for an iron sulfide mineral exposed to air over time.

Each specimen is entirely natural, with no artificial enhancement.

Size & Display Value (35–65mm)

With a size range of approximately 35–65mm, these pyrite specimens are ideal for:

• Mineral and crystal collectors

• Cabinet display collections

• Geological study and education

• Unique home décor accents

• Gifts for rock and fossil enthusiasts

The substantial size makes these pieces visually striking while still practical for shelving or display cases.

Collecting Interest & Traditional Associations (Non-Medical)

Pyrite has long been admired for its bold metallic appearance and strong presence in mineral collections worldwide. In spiritual traditions, it has been traditionally associated with themes of protection and abundance, though this listing focuses purely on its geological and collectible qualities, with no medical or outcome-based claims.
