Peridot

Peridot, with its distinctive green color, is graded based on specific criteria that determine its quality and value. These grading factors help gemologists and buyers assess peridot gemstones and make informed decisions. Here are the special specific grades of peridot:

Color Grade:

Intense Green: Peridot with an intense, pure green color is highly prized. These stones display a vibrant, rich green hue with good saturation. The most valuable peridot gemstones exhibit this intense green without any noticeable brown or yellow undertones.
Medium Green: Peridot gemstones with a medium green color are still desirable. While not as vivid as intense green peridots, they can display a pleasing and attractive green hue.
Yellowish-Green: Some peridots may have a yellowish-green tint. While these gems are less valuable than those with purer green hues, they are still appreciated for their unique color.

Clarity Grade:

Eye-Clean: Peridot gemstones that are free of visible inclusions to the naked eye are considered eye-clean and are highly valued.
Minor Inclusions: Peridots with minor inclusions that may be visible upon close inspection but do not significantly impact their beauty and durability.
Included: Peridots with noticeable inclusions that affect their transparency and brilliance. The type, size, and location of inclusions can influence their grade and price.

Cut Grade:

Ideal Cut: Peridot gemstones with precise and well-proportioned cuts that maximize their brilliance and color are graded as ideal. These cuts are often symmetrical and showcase the peridot's beauty.
Good Cut: Peridots with good but not perfect proportions that still exhibit good brilliance and color.
Poor Cut: Peridots with proportions that do not effectively reflect light and may negatively impact their beauty.

Carat Weight:

Large Carat Weights: Larger peridot gemstones are rarer and can command higher prices, especially if they possess high-quality color and clarity.

Treatment and Enhancement Grade:

Natural (Untreated): Natural peridots are often preferred for their natural beauty. Many peridot gemstones are not subjected to significant treatments.
Heat Treatment: Heat treatment is a common practice in the peridot industry. It is used to enhance the color and clarity of some stones. The extent of heating can affect the grade and price.

Other Treatments: Some peridots may undergo other treatments, such as surface coating or irradiation, to improve their color or appearance. The extent of such treatments can affect the grade and price.
