Blabbing About Baubles: Peridot

Today we’re talking about a gemstone I have come to be very fond of.

Peridot is a type of gem-quality olivine (olivine is a silicate mineral). Interestingly, peridot is one of the few gemstones which only exists in one color: olive green. The amount of iron in the gemstone determines how light or dark it can be.

It is found in lavas and xenoliths of the mantle. It can also be found in meteorites. It is not a rare gemstone, but it is rare to find peridot which is gem-quality. Peridot tends to be chemically unstable at the Earth’s surface, so it must be found at subterranean level.
