Olivine is named for its typically olive green color (thought to be a result of traces of nickel), though it may alter to a reddish color from the oxidation of iron Translucent olivine is sometimes used as a gemstone called peridot (péridot, the French word for olivine) It is also called chrysolite (or chrysolithe, from the Greek words for gold and stone).
Mohs Hardness Test
During the early 1800s, a German mineralogist named Friedrich Mohs devised a scale that tested mineral hardness, which means the resistance of a mineral to being scratched This scale, which ran from 1 to 10, was named after Mohs, and is known as the Mohs Hardness Test (Hardness should not be confused with brittleness.
