Mineral "Pyrite"

30 €

Elba, Italy, private collection from Netherlands.

The mineral pyrite or iron pyrite, also known as fool's gold, is an iron sulfide. Pyrite is the most abundant sulfide mineral. Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold. The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal. The name pyrite is derived from the Greek pyritēs lithos (πυρίτης λίθος), "stone or mineral which strikes fire". Pyrite occurs in numerous shapes and habits. The smaller crystal aggregates may give off a beautiful glistening effect in light, and the larger crystals may be perfectly formed, including fascinating cubes, penetration twins, and other interesting crystal forms. Pyrite has the same chemical formula as the rarer mineral Marcasite, but it crystallizes in a different crystal system, thereby classifying it as a separate mineral species. The condition of the sample is excellent. Beautiful pyrite crystals have bright silvery golden colour. Age-related wear, fractures and minor cracks may appear. Dirt and dust may exist. Size approx. 3,9cm x 3,6cm x 2,6cm. Weight c. 85g.
