(17,003 posts)Fools Gold 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. 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. Minerals can also have the same crystalline structure but different elemental compositions, but its the crystal structure that determines the minerals physical characteristics.
In addition to pyrite, common sulfides are chalcopyrite (copper iron sulfide), pentlandite (nickel iron sulfide), and galena (lead sulfide). The sulfide class also includes the selenides, the tellurides, the arsenides, the antimonides, the bismuthinides, and the sulfosalts. Many sulfides are economically important as metal ores.

We find that stuff around here in lots of places, but a piece like that would be a pretty good find.

(5,509 posts)The mineral is sitting on a mirror in a lightbox which has an array of 120 dimmable LEDs in its top. I used a silicone earplug to stick the pyrite to the mirror. The box also contains other objects and a blue backdrop of which colors are reflected in the pyrite's facets.
Thanks!

(5,509 posts)Pyrite's brassy-yellow and reflective. There are other objects and a blue backdrop in the box which colors are reflected in the facets of the mineral.
Thanks!
