The mineral olivine is a magnesium iron silicate. It is the common mineral on the earth's subsurface but weathers rapidly on the facade. Olivine is named for its classically olive -green blush, when the oxidation of iron takes place it convents it into reddish color. The ratio of iron and magnesium varies between to end members of the solid solution series. Its luster is vitreous and specific gravity leads from 3.27 to 3.37. The color ranges from yellow to yellow green. The crystal habit varies from massive to granular. It is also known as peridot. The moh's scale is having 6 to 6.5 that is the hardness scale.
Olivine is a dominant sterilizer. It releases and neutralizes toxins at all levels. It lightens the jealousy, resentment, spite, bitterness and irritation. It reduces anxiety, irritation and culpability. It opens our heart to discover innovative relationships and joy. It enhances self-reliance and allegation, rousing intensification and amends.

It poises the bipolar disorders and overcomes hypochondria. It works on solar plexus chakra and heart chakra.
When olivine is compressed it weathers instantaneously in few years, depending on the grain size. The reaction is exothermic but deliberate.
Olivine gemstones / crystals are found in some of the countries of world are: Austria, France, Poland
