Pyrite Fool's Gold Turtle Medium

Pyrite fool's Gold Turtle Medium

The mineral pyrite, or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS₂. 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.

Pyrite is the most widespread and abundant sulfide in the world and van be found in tens of thousands of localities with large and/or fine crystal being produced from Italy on Elba and at Piedmont, in Spain, Kazakhstan, in the United States from Colorado, Illinois, Arizona, Pennsylvania, Vermont, Montana, Washington, ...

Pyrite can be found in soils and sediments throughout the Earth as myriads of microscopic crystals. This pyrite is formed by bacteria that remove oxygen from sulfate in the water, producing sulfide that reacts with iron to form pyrite. More than 90 percent of the pyrite on Earth is formed by microbiological processes. 

Pyrite is the most common sulphide mineral in rocks of all ages, being found in virtually every geological environment.
