Pyrite
Material
Its metallic sheen and pale brass-yellow qualities can be confused with gold. This has led to its nickname, fool’s gold. It can be distinguished from natural gold by its hardness, brittleness and crystal form.
Description
Pyrite is the most abundant sulfide mineral and is found alongside quartz. Some of the most prized specimens come from the Soria and La Rioja provinces of Spain. The name comes from the Greek word pyr, “fire,” because it emits sparks when struck by metal. One of its early uses was in firearms. It was placed against a circular file to strike the sparks needed to fire the gun. Pyrite is also present in coal, when it burns, pyrite is oxidized releasing arsenic, an unfortunate trait that has contributed to lung disease in miners. In addition, being present in coal is the main source of acid gas, or greenhouse gas, in Earth’s atmosphere. In symbolism, pyrite has been considered a strong protection stone that shields its owners from negative energy strengthening the mind and willpower.
