What Affects Peridot Pricing?


Peridot stones are known for its bright, vibrant, green hue, and its color grade plays a major role in the gem’s value. Unlike some gems such as diamonds, the number of inclusions is not the main factor in the color grade. Instead, the richness of the color, which is garnered by its hue, saturation, and tone, is more important.

Generally, the more saturated the color, the more valued the gem will be, as saturated color means that inclusions are less visible. Peridot with a brownish tint is considered low quality and should be avoided.


As with any gemstone, an important determining aspect of peridot value is the carat/size of the gem. The gem’s color is at its best when in stones that are 10 carats or more, further increasing the value of larger stones.


Gemstones can be cut in many different styles depending on the type of jewelry it will be used for. Peridot cuts include round, cushion, oval, princess, emerald, and pear. The two most popular styles are round and emerald, which work well with the stone’s delicate crystal structure. In terms of ring styles the most popular styles of peridot rings are solitaire, halo, and three-stone, all of which can be purchased at With Clarity.

Production & Mining:

Natural Peridot vs Natural Treated Peridot

A major factor in determining the worth and value of this yellowish-green gem is how it is produced and mined. Natural varieties are the most rare and the most expensive, and high-quality natural peridot can be difficult to find. Therefore a great deal of this gem goes through heat treatment, which is an 100% natural way to improve the color and clarity of the stone. Heat-treated peridot is still considered real, and often results in a higher quality, more beautiful result.

At With Clarity, many naturally mined gems are heat treated to attain the most stunning result. Some peridot can also be made in a lab. The result is a stone that is visibly identical to its natural counterpart, with the only difference being the origin of the stone. Gemstones made in labs are also chemically the same, and often results in better color and saturation.

Buying Peridot

The price of peridot is determined by the color grade, cut, and carat of the stone, as well as how the gem was produced. When purchasing peridot it is important to consider your personal budget as well as the look you are aiming to achieve.

On average, natural peridot costs between $50-$80 per carat, though some higher quality stones can cost significantly more. Lab created peridot is more affordable and costs up to 40% less per carat.
