History and Lore
Peridot has a rich and storied history that dates back to ancient times. Known in various cultures and eras, this gemstone has been revered for its beauty and believed to possess protective and auspicious properties.
In Ancient Egypt, peridot was known as “the gem of the sun” and was closely associated with the sun god, Ra. It was often used in religious ceremonies and worn by priests and pharaohs as a symbol of divine power and protection. The Egyptians believed that peridot could ward off nightmares and bring about good fortune.
In Hawaiian legend, peridot is said to be the tears of Pele, the goddess of volcanoes. According to the myth, when Pele wept for her lost love, her tears turned into glowing green crystals, which were then embedded in the lava rocks of the islands. This story reflects the gemstone's connection with nature and its fiery origins.
Peridot was also highly valued by the ancient Romans and Greeks. The Romans referred to it as the “evening emerald” due to its resemblance to emerald but its more affordable price. It was commonly used in jewelry and amulets, believed to bring courage and protection to the wearer. The Greeks associated peridot with Apollo, the god of the sun, further reinforcing its solar symbolism.
In medieval Europe, peridot was often used in religious artifacts and church decorations. It was believed to have healing properties and was used in the treatment of various ailments. Some sources suggest that it was also used as a protective stone, especially for travelers, as it was thought to ensure safe passage and ward off evil spirits.
The modern designation of peridot as the August birthstone is a more recent development. While peridot has been known and used for millennia, its official status as a birthstone was solidified in the 20th century. This recognition reflects the growing appreciation for gemstones not just for their beauty, but also for their historical and symbolic significance.
Geological Formation and Sources
Peridot is a unique gemstone in that it is one of the few gemstones that can be found in both terrestrial and extraterrestrial environments. It is a variety of the mineral olivine and is composed of magnesium and iron silicate, with the chemical formula (Mg,Fe)₂SiO₄. The presence of iron gives peridot its characteristic green color, which can range from yellowish-green to deep, rich green.
The formation of peridot occurs in environments where magma cools slowly, allowing the crystal to grow. It is typically found in mafic and ultramafic igneous rocks, which are rich in magnesium and iron. Peridot is also found in meteorites, particularly in a type known as pallasites, where it is embedded in a matrix of iron-nickel alloy. These extraterrestrial occurrences add to the gemstone's mystique and highlight its connection to cosmic phenomena.
Major sources of peridot include the United States, China, Egypt, Brazil, and Myanmar. The United States, particularly the state of Arizona, is a significant source of high-quality peridot. The San Carlos Apache Reservation in Arizona is known for producing some of the finest peridot in the world. The deposits there are part of an ancient volcanic field, where peridot forms in basaltic rock.
China is another major producer of peridot, with the gemstone being mined in the Xinjiang and Yunnan provinces. These deposits are known for yielding large, high-quality stones. In Egypt, peridot has been mined for centuries, with historical records indicating its use in ancient Egyptian jewelry and artifacts. The gemstone is also found in Brazil and Myanmar, where it is often associated with other gem-bearing rocks.
The rarity of large, high-quality peridot stones is a key factor in their value. While peridot is not considered a rare gemstone in general, the finest specimens—those with vibrant green color and large sizes—are relatively scarce. This scarcity, combined with the gemstone's historical and cultural significance, contributes to its enduring appeal and value in the gemstone market.
Gemological Properties
Peridot is a remarkable gemstone with distinct physical and optical properties that make it both beautiful and desirable. Understanding these properties is essential for anyone interested in collecting, purchasing, or caring for peridot jewelry.
Color: The most notable characteristic of peridot is its vibrant green color, which is caused by the presence of iron in its chemical composition. The color can range from a yellowish-green to a deep, rich green. The finest peridot stones exhibit a pure green color with a slight yellowish tint, which is considered the most desirable. The intensity of the green color is directly related to the concentration of iron in the gemstone.
Hardness: On the Mohs scale of mineral hardness, peridot has a hardness of 6.5 to 7. This places it in the category of semi-precious gemstones, as it is harder than materials like glass and quartz but softer than gemstones like sapphire and ruby. While this hardness makes peridot suitable for use in jewelry, it also means that it can be scratched by harder materials. Therefore, it is important to handle peridot jewelry with care to avoid damage.
Clarity: Peridot is generally a transparent gemstone, although it can sometimes contain small inclusions or impurities. These inclusions are often visible to the naked eye and can affect the clarity of the stone. However, many inclusions are considered natural and are not necessarily detrimental to the gemstone’s value. In fact, some inclusions can add character and uniqueness to a peridot stone.
Cut and Shape: Peridot is typically cut into various shapes, including round, oval, emerald, and cushion cuts. The most common cut is the round brilliant cut, which enhances the gemstone’s brilliance and sparkle. The choice of cut can influence the gemstone’s appearance and value, with well-proportioned and symmetrical cuts being the most desirable.
Luster: Peridot has a vitreous (glassy) luster, which gives it a smooth and polished appearance. This luster is enhanced by proper cutting and polishing, which allows the gemstone to reflect light effectively.
Refractive Index and Double Refraction: Peridot has a relatively high refractive index, which contributes to its brilliance and fire. It also exhibits double refraction, meaning that light passing through the gemstone splits into two rays. This can sometimes be seen as a doubling of facets or a slight doubling of the back of the gemstone when viewed through the table.
Density and Specific Gravity: Peridot has a specific gravity of approximately 3.3 to 3.5, which is relatively high for a gemstone of its hardness. This density contributes to the gemstone’s weight and can affect its appearance when set in jewelry.
Other Properties: Peridot is not known to have any significant fluorescence under ultraviolet light, and it is generally stable under normal conditions. However, it can be sensitive to heat and should not be exposed to high temperatures, as this can cause it to lose color or become brittle.
Symbolism and Metaphysical Beliefs
Peridot has long been associated with a range of symbolic and metaphysical properties, many of which are rooted in ancient traditions and folklore. These beliefs vary across cultures and eras, but they often emphasize the gemstone’s protective and auspicious qualities.
In ancient Egypt, peridot was considered a sacred stone and was used in religious ceremonies and as a symbol of divine power. It was believed to ward off nightmares and bring about good fortune. The Egyptians also associated peridot with the sun god, Ra, and used it in jewelry and amulets to harness the sun’s life-giving energy.
In Hawaiian legend, peridot is said to be the tears of Pele, the goddess of volcanoes. According to the myth, when Pele wept for her lost love, her tears turned into glowing green crystals, which were then embedded in the lava rocks of the islands. This story reflects the gemstone's connection with nature and its fiery origins.
In medieval Europe, peridot was used in religious artifacts and church decorations. It was believed to have healing properties and was used in the treatment of various ailments. Some sources suggest that it was also used as a protective stone, especially for travelers, as it was thought to ensure safe passage and ward off evil spirits.
Modern metaphysical beliefs about peridot often emphasize its positive and energizing properties. It is considered a stone of transformation, helping to clear away negative emotions and promote a sense of well-being.

It is often used in meditation and energy healing practices to promote a sense of calm and clarity.
Peridot is also believed to enhance creativity and inspire new ideas. It is considered a stone of abundance and prosperity, making it a popular choice for those seeking to attract success and financial stability. In some traditions, peridot is also associated with friendship and is believed to strengthen bonds and promote harmony in relationships.
These diverse beliefs and associations highlight the enduring appeal of peridot and its role as a gemstone of both beauty and meaning.
Care and Cleaning
Proper care and cleaning are essential for maintaining the beauty and longevity of peridot jewelry. Given its relatively low hardness on the Mohs scale (6.5–7), peridot is more susceptible to scratches and damage compared to harder gemstones like diamonds and sapphires. Therefore, it is important to handle peridot jewelry with care and follow appropriate cleaning and storage practices.
Cleaning: Peridot can be cleaned using mild soapy water and a soft brush. A solution of warm water and a small amount of mild dish soap is effective for removing dirt and grime. Gently brush the gemstone with a soft-bristled brush, such as a toothbrush, and rinse it thoroughly with warm water. Avoid using harsh chemicals, abrasive cleaners, or ultrasonic cleaners, as these can damage the gemstone or its setting. Steam cleaning is also not recommended for peridot, as the high heat can cause the gemstone to lose color or become brittle.
Storage: To prevent scratches and damage, peridot jewelry should be stored separately from harder gemstones and metals. A soft pouch or a lined jewelry box is ideal for storing peridot pieces. This helps to prevent contact with other jewelry that may scratch the surface of the gemstone. When storing peridot, it is also advisable to avoid exposure to direct sunlight and high temperatures, as this can cause the gemstone to fade or lose its luster over time.
Wearing and Handling: Peridot jewelry should be removed before engaging in activities that may subject the gemstone to impact or abrasion. This includes sports, manual labor, and other activities where the jewelry may come into contact with rough surfaces. It is also a good idea to avoid wearing peridot jewelry when applying lotions, perfumes, or other cosmetics, as these can leave a residue on the gemstone that may dull its appearance.
Professional Cleaning and Inspection: For a deeper clean or to address any concerns about the condition of the gemstone, it is advisable to have peridot jewelry professionally cleaned and inspected by a qualified jeweler. A professional can ensure that the gemstone and its setting are in good condition and can provide additional care recommendations based on the specific characteristics of the piece.
