What is Fool's Gold?
Pyrite is considered the most common of the sulfide minerals. 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. The color has also led to the nicknames brass , brazzle , and Brazil , primarily used to refer to pyrite found in coal. By Georgius Agricola 's time, c. Pyrite is usually found associated with other sulfides or oxides in quartz veins , sedimentary rock , and metamorphic rock , as well as in coal beds and as a replacement mineral in fossils , but has also been identified in the sclerites of scaly-foot gastropods. Gold and arsenic occur as a coupled substitution in the pyrite structure. In the Carlin—type gold deposits , arsenian pyrite contains up to 0.
Sulfide minerals are a group of inorganic compounds containing sulfur and one or more elements. Minerals are defined by their chemistry and crystalline structure. Minerals that have the same chemical composition but different crystal structures are called polymorphs. Pyrite and marcasite, for example, are polymorphs because they are both iron sulfide, but each has a distinct structure. In addition to pyrite, common sulfides are chalcopyrite copper iron sulfide , pentlandite nickel iron sulfide , and galena lead sulfide.

What Is Fool's Gold?
Pyrite with Striations: A cluster of cubic pyrite crystals exhibiting prominent striations. Pyrite received that nickname because it is worth virtually nothing, but has an appearance that "fools" people into believing that it is gold. With a little practice, there are many easy tests that anyone can use to quickly tell the difference between pyrite and gold. The nickname "fool's gold" has long been used by gold buyers and prospectors, who were amused by excited people who thought they had found gold. These people did not know how to tell the difference between pyrite and gold, and their ignorance caused them to look foolish. This specimen is visually appealing and displays the crystalline habit of gold. The value of this specimen to collectors of crystalline gold would be many times the value of its contained gold.
Any flashy but ultimately worthless investment may be called fool's gold in finance. The term originally referred only to iron pyrite, which is commonly mistaken for gold. In finance, the term refers to an investment believed to be valuable that later ends up worthless or near worthless. Iron pyrite is a shiny mineral composed of iron disulfide. It looks somewhat like real gold, so it came to be called fool's gold. Fool's gold was often found during the gold rush of the s in the U.
