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.
Different colors of peridot gems represent different things. For instance, an iron-rich, yellow peridot supposedly helps cure health problems associated with kidneys, the bladder, the gall bladder, and the stomach. A green, magnesium-rich peridot, on the other hand, represents financial success (Jewels).
