Very soft mineral
Iron Oxide. Pyrite is known also as "Fool's Gold"
Iron pyrite, a mineral composed of iron sulfide, FeS, is called fool's gold because it has the appearance (but no other properties) of gold.
Zircon is the oldest known mineral, at over 4 billion years, but the youngest is impossible to say. Minerals are forming all over the Earth at this very moment. You could perhaps safely say that the youngest will be found in the rock of the the latest volcanic eruption.
Pyrite can be identified as a bright-yellow mineral, with a bright-metallic luster. Pyrite can be used to spark a fire if struck against metal or another hard material. Pyrite was used as a spark-producing material in flintlock firearms.
== == Pyrite is iron sulfide, a mineral composed of sulfur and iron. It's also known as "Fools'Gold" because of its shiny yellowish metallic luster. Pyrite can be found in sedimentary, magmatic, and metamorphic rock deposits, and also in hydrothermal vents, wherever there is sulfur and iron.Pyrite is sometimes an ore of gold and copper. It is also an ore of sulfur, which is used in the production of tires, explosives, disinfectants, medicines, ink, wood preservatives, dyes, matches, and sulfuric acid. Some collector specimens can be quite valuable as well. The streak of pyrite is greenish-black. Pyrite is in the cubic/isometric crystal system where three axes running through the center of the crystal are of equal length and form an angle of 90 degrees at intersection.
It is known as calcite, the main mineral of limestone and marble.

Fools gold is iron sulphide (FeS2) or also known as pyrite.
Iron sulfide, FeS2, makes up the crystalline mineral pyrite, also known as fool's gold.
