Historical & Geological Background:
Pyrite (iron sulfide, FeS₂) is a widespread mineral found in hydrothermal veins, sedimentary rocks, and coal deposits. It is well known for its metallic lustre and often cubic crystal habit, which gives it a strong resemblance to gold and the nickname “Fool’s Gold.”

Peru is a key source of high-quality pyrite, especially specimens with well-formed cubic crystals and bright metallic surfaces. Historically, pyrite has been used in fire-starting tools due to its ability to produce sparks when struck against steel, and it remains an important mineral in geological and collector markets today.
