About Pyrite

Pyrite is an iron sulfide mineral (FeS2) commonly known as "fool's gold" due to its brassy yellow metallic luster that can resemble real gold to the untrained eye, though it is much harder and more brittle than actual gold. This cubic crystal system mineral forms distinctive geometric shapes including perfect cubes, octahedrons, and pyritohedrons, creating naturally occurring specimens that appear almost artificially crafted due to their precise geometric forms. Pyrite's name derives from the Greek word "pyr" meaning fire, referencing the sparks it produces when struck against metal or flint, and it has been used since ancient times for both practical fire-starting purposes and decorative applications.

• Color range: Brassy yellow to pale gold with bright metallic luster; some specimens show iridescent tarnish in purple, blue, or green tones
• Sizes: Available from small crystal clusters (1-2cm) to large specimen pieces (several inches); dramatic geometric forms in all sizes
• Shapes: Naturally occurs in perfect cubes, octahedrons, and complex geometric forms; also found as nodules and irregular masses
• Origin: Worldwide including Peru, Spain, Italy, and Colorado; Peruvian material often produces the finest crystal specimens
• Hardness: 6 to 6.5 on Mohs scale, harder than real gold, making it durable for jewelry applications with proper setting techniques
• Crystal structure: Cubic system creating remarkable geometric precision; natural specimens often appear artificially crafted
• Luster: Brilliant metallic luster when fresh; may develop colorful tarnish over time that adds to its visual appeal
• Identification: Distinguishable from gold by its hardness, brittleness, and tendency to produce sparks when struck
