The following sections will explore the origins of peridot, its physical and chemical properties, its role in history and culture, and how to care for this gemstone to preserve its beauty.
History and Lore
Peridot has a long and storied history that spans multiple civilizations. The word “peridot” comes from the Arabic faridat, meaning gem. This August birthstone was valued in many ancient and medieval cultures. One of the earliest known sources of peridot was the Red Sea island of Topazios, which is now known as Zabargad. This island was a significant source of peridot, and it is believed that the name “topaz” may have originated from this island. The gemstones from Topazios were often mistaken for emeralds due to their similar green color.
Peridot has also been found in the Shrine of the Three Holy Kings in Germany’s Cologne Cathedral, where it was originally thought to be emeralds. This misidentification highlights the visual similarities between peridot and other green gemstones. Some historians even speculate that Cleopatra’s famous emerald collection may have been comprised of peridot, further emphasizing its historical significance.
Peridot’s association with ancient and medieval cultures demonstrates its enduring appeal. Its presence in religious and royal artifacts underscores its value as both a decorative and symbolic gemstone. As peridot transitioned into the modern era, its beauty and unique properties continued to make it a favored gemstone among jewelers and collectors.
Geological Formation and Sources
Peridot is formed under extreme geological conditions, which contribute to its unique properties. It is found in the hardened lava that carried it from deep within Earth’s mantle, as well as in meteorites that traveled from outer space. This dual origin—both terrestrial and extraterrestrial—adds to the intrigue of peridot and sets it apart from other gemstones.
The formation of peridot begins deep within the Earth’s mantle, where it crystallizes from molten rock. As the molten rock cools and solidifies, it forms the green gemstone. Peridot can also be found in meteorites, making it one of the few gemstones that have an extraterrestrial origin. This unique formation process gives peridot a distinct character that is both rare and fascinating.
Peridot is found in several locations around the world, each contributing to its global supply. The Red Sea island of Zabargad remains one of the most significant sources of peridot. Other notable sources include Arizona in the United States, New Mexico, and various locations in Brazil, China, and Egypt. These regions provide a diverse range of peridot, each with its own unique characteristics and qualities.
The presence of peridot in both terrestrial and extraterrestrial environments highlights its geological significance. Its formation under extreme conditions and its occurrence in meteorites make it a valuable subject for geological research and study. This dual origin also adds to the allure of peridot as a gemstone, making it a symbol of both Earth and the cosmos.
Gemological Properties
Peridot is a unique gemstone with distinct gemological properties that make it stand out in the world of gemstones. It is the yellowish green to greenish yellow gem variety of the mineral olivine. The color of peridot is due to the presence of iron within its chemical structure. This iron content is responsible for the gemstone’s characteristic green hue, which can range from a pale yellow-green to a deep olive green.
One of the key gemological properties of peridot is its hardness. On the Mohs scale of mineral hardness, peridot ranks between 6.5 and 7. This hardness level makes peridot suitable for use in jewelry, although it is not as hard as some other gemstones such as diamonds or sapphires. The hardness of peridot means that it is relatively durable but requires careful handling to avoid scratches and other damage.
Peridot also has a refractive index that contributes to its brilliance and luster. The refractive index of peridot is between 1.65 and 1.69, which gives it a moderate level of sparkle. This refractive index is lower than that of other gemstones such as diamonds or sapphires, but it is still sufficient to make peridot an attractive and eye-catching gemstone.
The chemical formula of peridot is (Mg,Fe)₂SiO₄, which indicates that it is a magnesium iron silicate. This chemical composition is responsible for its green color and its other physical properties. Peridot is also known for its inclusions, which are small imperfections that can be seen within the gemstone. These inclusions are not considered flaws but rather a natural part of the gemstone’s character.
Peridot is typically cut in a variety of shapes to enhance its beauty and to showcase its green color. Common cuts include the round brilliant, oval, cushion, and emerald cuts. Each cut is designed to maximize the gemstone’s brilliance and to highlight its unique characteristics. The choice of cut can also affect the overall appearance and value of the gemstone.
The size of peridot gemstones can vary, but they are generally available in a range of sizes from small to medium. Larger peridot gemstones are relatively rare, making them more valuable. The size of the gemstone can also affect its color intensity, with larger stones often displaying a more vibrant green hue.
Peridot is a transparent to translucent gemstone, which means that it allows light to pass through it. This transparency contributes to its overall beauty and makes it a popular choice for jewelry. The combination of its color, hardness, refractive index, and transparency makes peridot a versatile and attractive gemstone.

Care and Cleaning
Peridot requires proper care and cleaning to maintain its beauty and longevity. Given its hardness of 6.5 to 7 on the Mohs scale, peridot is relatively durable but still requires careful handling to avoid scratches and other damage. The following are some guidelines for caring for and cleaning peridot gemstones.
One of the most important aspects of caring for peridot is to avoid exposing it to harsh chemicals. Peridot can be sensitive to certain chemicals, which can cause damage to the gemstone. It is advisable to remove peridot jewelry before using cleaning products, as these products can contain harsh chemicals that may affect the gemstone.
Peridot should also be protected from extreme temperatures. Exposure to high heat or cold can cause the gemstone to crack or become damaged. It is best to store peridot in a cool, dry place away from direct sunlight and extreme temperatures.
Cleaning peridot can be done using a soft cloth and mild soap and water. A soft brush can also be used to gently clean the gemstone. It is important to avoid using ultrasonic cleaners or steam cleaners for peridot, as these can cause damage to the gemstone. Ultrasonic cleaners can cause the gemstone to become loose in its setting, while steam cleaners can cause the gemstone to become overheated.
Peridot should be stored separately from other gemstones to prevent scratches. It is best to store peridot in a soft cloth or a jewelry box with individual compartments to protect it from other gemstones and jewelry. This will help to prevent scratches and other damage that can occur when gemstones come into contact with each other.
Regular inspection of peridot jewelry is also important to ensure that the gemstone remains secure in its setting. If the gemstone becomes loose, it should be checked by a professional jeweler to prevent it from becoming dislodged or lost.
By following these care and cleaning guidelines, peridot can be preserved for many years. Proper care will help to maintain the gemstone’s beauty and ensure that it remains a cherished and valuable piece of jewelry.
