This polished sphere is crafted from natural pyrite, also known as “fool’s gold,” highlighting its metallic luster and brassy color. Spherical polishing emphasizes the mineral’s reflective surfaces and crystalline structure.
Details:
- Mineral Group: Sulfide
- Chemical Formula: FeS₂ (iron sulfide)
- Size: Approximately 2.5 inches in diameter
- Appearance: Metallic gold-colored sphere with natural crystalline texture visible under polish
- Formation: Forms in sedimentary, metamorphic, and igneous rocks, often alongside quartz
- Physical Properties: Mohs hardness 6–6.5; metallic luster; brittle with a greenish-black streak
- Educational Value: Demonstrates sulfide mineral formation, cubic crystal habit, and reflective mineral properties
A polished pyrite sphere offers both visual appeal and a clear example of natural mineral formation.
