How a peridot gemstone is formed

The peridot gemstone is a distinct gemstone, which has a yellow-green color, these maybe all the things that we know about the gems. About its formation here I will give you some information to let you learn more about it.
It is said that the peridot gemstone is a form of olivine, which are in yellow, pale green or even black color and can be found in many rocks such as basalt, volcanic rock and even the earth's mantle. The olivine is not the right form of the peridot, only when olivine crystallizes, it can turn into the peridot. They can usually be found in volcanic rock and the mantle of the earth, because it has a very high melting point. If you want to make a peridot from the olivine, you should put the olivine in high temperature and pressure. Today, most of the peridot is mined, often by hand, and they are usually made into relatively small sizes. Some are rare in sizes above five carats. This stone can easily be found at night, since its green color did not darken at night so a lot of miner tends to pick them out during night, but you can still find them with the help of the lamplight. Usually they can find beautiful large crystals of peridot, some that cut magnificent large gemstones.
About the formation of the peridot gemstone, I just list a little part for you, you can still learn more through other approach. Hope what I show above can still give you a help.
