Pyrite

Carat weight is less important than overall crystal form and aesthetic appeal. Pyrite occurs in large masses and clusters, so smaller cabochons or beads are inexpensive. Larger, well-formed cubes, suns or nodules with sharp edges and attractive reflections can command higher prices as collector or designer pieces.

Color and metallic luster are key. The most desirable pyrite exhibits a bright, even, brassy-gold color with strong reflectivity. Dull, tarnished or heavily oxidized material is less attractive; some darkening and patina may be acceptable in antique or specimen contexts.

For pyrite, clarity equates to structural integrity and surface condition. Clean crystals or cabochons with minimal fractures, pits and crumbly zones are preferred. Stones that shed dust or show significant internal cracking are less suitable for jewelry and have lower value.

Pyrite is often used in its natural crystal forms (cubes, pyritohedra) for collectors or cut into beads and cabochons for jewelry. When cut, a smooth, even polish enhances its metallic sheen. Intricate faceting is rare and primarily of curiosity value. Care is needed to avoid chipping edges during cutting and setting.

Pyrite is abundant in many geological environments, including hydrothermal veins, sedimentary rocks and metamorphic deposits. Commercial quantities suitable for ornamental use are readily available from multiple countries, including Peru, Spain and the United States.

Demand is steady in the metaphysical and decorative markets, with pyrite used for tumbled stones, clusters and jewelry elements. Its association with abundance and wealth in crystal lore supports ongoing sales, but it remains a low-cost material.
