Understanding these types can enhance your appreciation and help you make informed decisions when purchasing or collecting.
What Are the Different Types of Peridot?
Peridot is primarily classified based on its origin, color, and clarity. The primary types include Olivine, Forsterite, and Fayalite. Each type has unique features that influence its appearance and value.
Types of Peridot Based on Composition
1. Olivine Peridot
Olivine is the general mineral family to which peridot belongs. This type is rich in magnesium and iron, giving peridot its signature green color. The balance of these elements affects the shade of green, ranging from yellow-green to olive.
2. Forsterite Peridot
Forsterite is a magnesium-rich variety of olivine. It is often the most sought-after due to its vibrant green hue. Forsterite peridot is typically found in volcanic regions and is prized for its clarity and brilliance.
3. Fayalite Peridot
Fayalite contains a higher iron content, resulting in a darker green or brownish-green color. While less common in jewelry, fayalite peridot is valued by collectors for its unique appearance.
Types of Peridot Based on Origin
Peridot is sourced from various locations worldwide, each contributing to its distinct characteristics.
1. Arizona Peridot
Arizona is one of the largest sources of peridot, particularly from the San Carlos Apache Reservation. Arizona peridot is known for its bright, lime-green color and excellent clarity, making it a popular choice for jewelry.
2. Egyptian Peridot
Historically mined on the island of Zabargad, Egyptian peridot has a rich history dating back to ancient times. It is often deep green with a slight golden tint, adding to its allure.
3. Burmese Peridot
Mined in Myanmar, Burmese peridot is often considered the finest quality due to its intense green color and exceptional clarity. Its vibrant hue makes it highly coveted among gem enthusiasts.
How to Evaluate Peridot Quality?
When assessing peridot, consider several factors to ensure you select the best quality gemstone:
- Color: The most desirable peridot is a pure grass-green without any brown or yellow undertones.

- Cut: A well-cut peridot enhances its brilliance and color, making it more attractive.
- Carat Weight: Larger peridot stones are rarer and can be more valuable, but the quality should not be compromised for size.
