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.
The most expensive Peridots are sparkling lime-green without brown or yellow hues. The color of the August birthstone ranges from lime green to olive green, dark green and yellowish green. Chrysolite is the golden yellow variant of Peridot.
