24 Best Pyrite imagesFool gold, Crystals, Chemical formula

Aug 9, 2021 Pyrite, more properly called iron pyrite, is a famous mineral with the chemical formula FeS2 (iron sulphide). Its nickname is "fools gold" owing to its golden color, and it a very common mineral found in a wide variety of environments all over the world. Pyrite is not all that difficult to distinguish from pure gold It has a hardness of 6-6.5 (Mohs) much harder than gold (and

Pyrite has a cubic structure, metallic luster and a yellow-gold color that has earned it the nickname "fool's gold". With a hardness of 6 to 6.5 on the Mohs scale, pyrite is hard enough to be used in jewelry. Pyrite is also exceptionally dense, with a specific gravity of 5.0 to 5.2. Only hematite has a higher density.
