Peridot is relatively well-known as a gemstone, particularly since its the birthstone for August. Peridot is relatively hard, with a rating of 6.5-7 on the Mohs scale. While there can be some small inclusions or veils of bubbles, the best gems are flawless and a pure bright light green to a light yellowish-green.
There are no named varieties or species of peridot.
