Copper Pyrite

Raw copper pyrite, 14.6 grams. This incredible specimen of copper pyrite originates from Chile and measures 45 x 25 x 12 mm. The surface of the stone is covered with small tetragonal pyrite crystals. Its structure and beautiful metallic yellow coloration make it a striking stone, worthy of any collection. It belongs to the cubic system and is classified within the sulfide group, with the chemical formula FeS₂. Pyrite is a very common mineral, found in a multitude of geological formations, from sedimentary deposits to hydrothermal veins. It is composed of 53% sulfur and 47% iron. It has a cubic shape, sometimes with cemented faces, and is also frequently found in octahedrons, pyritohedrons (twelve pentagonal faces), and rarely icosahedrons (twenty triangular faces). Pyrite is known as fool's gold due to its great resemblance to it. Origin: Chile
