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.
Faceted Peridot stones typically are not larger than a few carats, and some of the stones in this update are in the 7-8 carat range! All of the stones are well cut and have a vibrant green color. Due to the fact that these stones have some kind of minor inclusions, they are discounted at over 30% off our retail price. Honestly, due to the fact that the stones are so greatly magnified, the inclusions look worse than they do in preson.
