Pyrite is also known as "fools' gold" because of its colour and shape.
Pyrite is popular for its crystal habit, hardness, streak, lustre and brittleness.
Its composition is of iron disulphide having a pale brass-yellow colour. The name "pyrite" is derived from the Greek words "pyrites lithos," which mean "stone which strikes fire," in allusion to the sparking produced when iron is struck by lump of pyrite.
Pyrite is believed to be a stone which can spark creative thinking and open a person to new ideas. Iron pyrite is believed to be a very protective stone and should be carried when performing dangerous work. It stimulates the powers of the intellect. Sunflower pyrite is said to be a protective stone. It shields one from any negative energy and aids physical and emotional well-being.
