Pyrite, also called fool's gold. Pyrite is an iron sulfide mineral that resembles gold with its pale, brass-yellow hue. It derives its name from the Greek word for fire due to its ability to produce sparks when struck against steel. It is considered a gemstone by some and has been used in the production of marcasite jewelry.

Minerals Native Mineral Iron Five percent of Earth's crust is made up of iron. Native iron is rare in the crust and is invariably alloyed with nickel. Low-nickel iron (up to 7.5 percent nickel) is called kamacite, and high-nickel iron (up to 50 percent nickel) is called taenite. Both crystallize in the cubic system.

A typical arsenical gold ore contains arsenopyrite as the major arsenic mineral. However, some arsenical gold ores, such as those from Nevada in the USA (Getchel deposit), contain realgar and orpiment as the major arsenic-bearing minerals. Pyrite, if present in an arsenical gold ore, may contain some gold as minute inclusions.

Because gold doesn't have any value in that sense, a health scientist would not include gold in their rundown of minerals, even if copper, iron, and zinc would be. Also, typically when it comes to purchasing gold, people think of it as a commodity, which aligns it more closely with an earth science perspective.

Gold in its natural mineral form almost always has traces of silver, and may also contain traces of copper and iron. A Gold nugget is usually 70 to 95 percent gold, and the remainder mostly silver. The color of pure Gold is bright golden yellow, but the greater the silver content, the whiter its color is.

Native Element Minerals. Native element minerals are composed of a single element, resulting in very simple chemical formulas! Examples include gold (Au), silver (Ag), platinum (Pt), sulfur (S), copper (Cu), and iron (Fe). Diamond and graphite are also native element minerals, both composed entirely of carbon. The ways in which the carbon atoms are bonded dictates their very different properties.
