How much is it? On average, a high-quality peridot stone can cost anywhere from $50 to $200+ per carat. Larger peridots that are exported from foreign countries can cost as much as $500+ per carat. Generally, stones mined from Burma, Pakistan and Arizona can command the highest prices.
Peridot gems can also be referred to as olivine, which is an iron and magnesium-rich mineral found on Earth. The word peridot is derived from the Arabic word Zabargad, which means peridot (Mineral Miners, 2007). Peridot also has another variety, or type, called chrysolite, which is yellow colored. The word chrysolite is Greek for yellow stone. A fair share of peridots are green though, which is how the mineral olivine got its name--from the color olive.
