Foolâs Gold for April Foolâs Day. âFoolâs Goldâ is technically known as pyrite or iron sulfide (FeS2) and is one of the most common sulfide minerals. Sulfide minerals are a group of inorganic compounds containing sulfur and one or more elements. Minerals are defined by their chemistry and crystalline structure.
You can try to scratch it because pyrite or fools gold much harder then gold so if it doesn't scratch that much it is most likely pyrite or fools gold. You can tell them apart by looking at their reflection and streak. Also, gold is much more dense than pyrite, so the same volume would 'weigh' about 3.5 times more. Gold has a hardness of about 2.5, while pyrite is about 6 (Gold is softer and more malable). Streak is used to distinguish between Gold and Pyrite. Pyrite also known as fool's gold is a mineral that has both a different chemical, morphological and physical characteristics than gold. Gold is denser (i.e. the same size of gold is much heavier than the that of pyrite). Gold's average density is 17.64 g/cm3 while Pyrite's density is on average 5.01 g/cm3.
