It is not very clear where the name comes from. Some suggestions are that is comes from the arabic word "faridat" (gemstone), the Middle English word "peridote" (bright spot or button) or the word „peridona“ (to give abundantly). In some other countries peridot had originally the greek name „chrysolite“ (goldstein), however, the name peridot prevailed.
The peridot is one of few gems that exists in only one color - green. The green palette ranges from bright green, pistachio or olive-like yellowish green – which occur most frequently – to a green with a slightly brownish tone. The pure grass-green peridot is the most valuable one.
The peridot is usually cut in a faceted form ranging from oval, emerald to cushion cut.
Cabochon cut: This shape is an unfaceted, round or oval cut, in which the underside is flat and the top is arched outwards. The cabochon cut accentuates and enhances the shimmer inherent in the stone's structure. Those shimmers are especially vivid in cat's eye quartz, falcon and tiger's eye, moonstone and opals.
Faceted cut: There is wide variety of faceted cuts - some of them are displayed in the picture to your right.
The peridot belongs to the group of silicates and occurs only in shades of green which he receives from the element iron. The trace elements chromium or nickel can make the color appear even more intense.
Most of the peridots can be found in Egypt and Tanzania. Other locations where the gemstone can be found are China, Myanmar, Pakistan, United States and Vietnam.
The Mohs hardness describes the hardness of a mineral on a scale of 1 to 10 and is named after its inventor, the German mineralogist Friedrich Mohs (1773 - 1839). It is the basis of the hardness test. Friedrich Mohs scored various minerals against each other and arranged them according to their hardness. The scale consists of a series of 10 minerals, each of which "scratches" all standing in front of him. Diamonds have a Mohs hardness of 10 and are therefore the hardest minerals.

Also the peridot should not be exposed to extreme temperature fluctuations since it can lead to damages in the stone. The best way to care for an peridot is to clean it with warm, soapy water and a soft cloth.
Not recommended: Ultrasonic and steam cleaning and subject to heat.
