Collectible minerals - full range in stock "Pyrite"

Pyrite - translated from Greek as "a stone that strikes fire", because. has the property of sparking. Used as a replacement for flint in flintlock guns. Other names are sulfur or iron pyrites.

Forms cubic, pentagondodecahedral, cuboctahedral, octahedral (the rarest) crystals. Crystals can be both with shading on the edges (for example, the Berezovsky deposit, the Urals), and absolutely smooth (Navakhun, Spain).

Outwardly, it resembles gold, accompanying it in deposits, which is why pyrite was often confused with it during mining. Because of this, it was called "fool's gold". Pyrite is widely distributed. In Russia, its deposits are in the Urals, Altai, the Caucasus, in Komi, in the Voronezh region.

Pyrite crystals are used in the simplest detector radios as a diode, using the property of the pyrite-metal pair to pass current mainly in one direction. Previously, pyrite was used as mirrors, for which it was polished to a shine.

You can see pyrite stone for sale and buy it in the Minerals of Russia online store.
