Peridot and the 4C's
As with most gemstones, you should be mindful of the 4C's when you shop for Peridot jewelry. The 4C's are:
- Carat, or size: Inexpensive in small sizes, a large Peridot gem can be very valuable.
- Color: Unlike many gems, Peridot only comes in shades of green.
- Cut: Available in many shapes, Peridot exhibits added sparkle and brilliance when well cut.

Peridot gemstones have a fairly narrow color range. Most of the Peridot jewelry you find will sport yellowish green stones. However, the stone may be found in colors from a brown-green to a pure green. Peridot stones with a brownish color are considered to be lower quality and will have less value.
What Shapes can a Peridot be Cut Into?
Gemstones may be cut in a wide variety of styles and shapes. Although you can find this olivine stone in round, oval, pear, cushion, triangle, and marquise shapes, you will notice that round and emerald shapes are the most popular.
Round
This is the shape most associated with classic engagement rings. With its allowance for mathematically precise cuts, a round Peridot maximizes light and brilliance.
Emerald
Emerald shaped Peridot gemstones are step cut. This means that the gem sports small rectangular facets resembling stairs or steps. It is the nature of these cuts that gives an emerald-shaped gems an added level of sparkle and brilliance.
Peridot's Clarity
Although better-quality Peridot have no inclusions visible to the naked eye, these stones often have small inclusions. You will often find tiny mineral crystals within the body of this olivine gemstone. These tiny flaws will look like tiny black spots under magnification. Peridots may also have disk-shaped inclusions that are referred to as "lily pads." You will find the clarity of a Peridot graded from AAAA,AAA,AA, to B.
- AAAA or best grading is reserved for natural gems with few inclusions and exceptional color.
- AAA or better grading will indicate that the stone you are considering is of exceptional quality with good color and few inclusions.
- AA grading, while still indicating a good gem, will indicate that there are more inclusions in the stone. These stones may have more muted color and less brilliance.
- B grades indicate a gemstone with more inclusions and less engaging color. You may find gemstones with brownish green color and visible flaws in this category.
Heat-treated Peridot
You will find that many natural Peridot gemstones are treated to enhance color and reduce the appearance of naturally occurring inclusions. Gemstones are heat treated to achieve a color and finish that will truly shine. Heat treatment is 100% natural and permanent. Gems can achieve a higher color and clarity grade through this treatment. The vast majority of gemstones used in jewelry are heat treated.
