For those born on August 21, the birthstone is the vibrant and storied gemstone known as Peridot. This gem, with its distinctive yellow-green to greenish-yellow hues, has captivated the human imagination for millennia. Unlike many other gemstones that can appear in a range of colors, Peridot is unique in that it only occurs in green, a coloration derived from the iron in its chemical structure. Peridot is more than just a beautiful gem; it is a symbol of renewal, positivity, and emotional balance. This article will explore the rich history of Peridot, its geological formation, its gemological properties, its symbolic and spiritual significance, and how to care for it as a treasured piece of jewelry.
History and Lore
Peridot has a long and fascinating history that spans ancient civilizations. Known in antiquity as the “gem of the sun,” it was highly valued for its protective and spiritual properties. The ancient Egyptians mined Peridot from the Red Sea island now known as Zabargad, or St. John’s Island. They believed that the gemstone could protect against evil spirits and bring good fortune. This belief was particularly strong when Peridot was set in gold, a combination that was common in Egyptian jewelry.
During the medieval period, Peridot was also used in religious ceremonies and was often incorporated into ceremonial jewelry and seals by priests and religious leaders. Its bright green color symbolized life and renewal, making it a valuable gemstone for spiritual rituals. Medieval churches frequently adorned their treasuries with Peridot jewels, believing them to possess special protective powers. In fact, the Shrine of the Three Holy Kings in Germany’s Cologne Cathedral is decorated with 200 carats of Peridot that were once thought to be emeralds.
The name "Peridot" itself is derived from the Arabic word "faridat," meaning "gem." This etymological link highlights the gem’s historical significance in the Middle East, where it was highly prized. Some historians even speculate that Cleopatra’s famous emerald collection may have consisted largely of Peridot, a theory supported by the fact that Peridot was often mistaken for emerald due to its similar green color.
In addition to its use in jewelry and religious artifacts, Peridot was also believed to have healing properties. Ancient cultures associated it with the heart chakra, viewing it as a stone of compassion and emotional balance. It was thought to dispel negative emotions such as jealousy and resentment, promoting confidence, joy, and abundance. These beliefs have persisted into modern times, with Peridot still being valued for its calming and positive energy.
Peridot’s unique place in history is further emphasized by its geological origin. Unlike most gemstones that form in the Earth’s crust, Peridot originates deep within the Earth’s mantle, forming under extreme heat and pressure. It is one of only a few gemstones, alongside diamonds, to form at such depths. In rare cases, Peridot can also be found in meteorites, adding to its mystique and scientific interest.
Geological Formation and Sources
Peridot is a variety of the mineral olivine, a silicate mineral composed primarily of magnesium and iron. Its formation process is both unique and fascinating. Peridot forms under extreme conditions in the Earth’s mantle, where temperatures and pressures are exceptionally high. The presence of iron in its chemical structure is what gives Peridot its characteristic green color. The more iron a Peridot contains, the deeper its green tone becomes.
The gemstone is found in a variety of geological settings. One of the most notable sources of Peridot is the island of Zabargad in the Red Sea, where it has been mined for centuries. The gems found there are so naturally lustrous that they are referred to as “spirit polished.” Other significant sources of Peridot include the United States, particularly in Arizona and New Mexico, where it is found in volcanic rocks. Madagascar, Myanmar, and China are also known for producing high-quality Peridot.
In addition to terrestrial sources, Peridot can also be found in meteorites. This extraterrestrial origin makes Peridot one of the few gemstones that have traveled from outer space to Earth. Meteorite Peridot is particularly rare and valuable due to its unique origin and the fact that it forms under conditions that are not replicable on Earth.
The process of mining Peridot varies depending on the location. In some areas, it is found in surface deposits and can be collected relatively easily. In other cases, it is embedded in lava flows or volcanic rocks, requiring more extensive mining techniques. The gems are typically extracted using traditional methods such as hand picking and sieving, as the softness of the gemstone makes it susceptible to damage from heavy machinery.
Despite its widespread distribution, Peridot is not commonly found in large quantities. This scarcity, combined with its unique color and historical significance, contributes to its value in the gemstone market. High-quality Peridot, especially those with a deep green color and excellent clarity, can be quite valuable, making them sought after by collectors and jewelry designers alike.
Gemological Properties
Peridot is a remarkable gemstone not only for its beauty but also for its unique gemological properties. It is a variety of the mineral olivine, a silicate mineral composed of magnesium, iron, and oxygen. The chemical formula for Peridot is (Mg,Fe)₂SiO₄, with the presence of iron being responsible for its green color. The more iron a Peridot contains, the deeper its green tone becomes.
One of the most distinctive characteristics of Peridot is its color. Unlike many other gemstones that can appear in a wide range of colors, Peridot is only found in green. This is due to the presence of iron in its chemical structure. The green color can vary from a pale yellow-green to a deep, rich green, depending on the concentration of iron. This unique coloration makes Peridot stand out among other gemstones and is a key factor in determining its value and desirability.
Peridot has a hardness of 6.5 to 7 on the Mohs scale, which means it is relatively soft compared to other gemstones such as sapphire or ruby. This makes it more susceptible to scratches and damage, especially when worn in rings or other jewelry that is subject to daily wear. As a result, Peridot is best suited for jewelry that is worn less frequently, such as pendants or earrings.
Another important gemological property of Peridot is its refractive index. Peridot has a refractive index of 1.65 to 1.69, which means it has a moderate to high level of light refraction. This property contributes to its brilliance and makes it a desirable gemstone for jewelry. However, Peridot does not display the same level of brilliance as diamonds or other high-refractive-index gemstones.
Peridot is also known for its pleochroism, a property that allows it to display different colors when viewed from different angles. While this effect is subtle in Peridot, it can be observed in some specimens, adding to the gemstone’s visual interest.
In terms of clarity, Peridot is generally included, meaning it often contains small inclusions or imperfections. These inclusions can affect the gemstone’s clarity and, in some cases, its durability. However, many of these inclusions are not visible to the naked eye and do not detract from the gemstone’s beauty. High-quality Peridot with excellent clarity is rare and highly valuable.

Symbolism and Metaphysical Beliefs
Peridot is a gemstone rich in symbolism and metaphysical significance. Known as the “stone of compassion,” it is associated with kindness, renewal, and emotional balance. Its connection to the heart chakra makes it a powerful symbol of unconditional love, healing, and emotional growth.
One of the key symbolic elements of Peridot is its association with light and positivity. It is believed to dispel negative emotions such as jealousy and resentment while promoting confidence, joy, and abundance. This association with positivity and renewal is reflective of the gemstone’s natural color, which embodies the lush and rejuvenating aspects of nature.
In ancient times, Peridot was believed to have protective properties. It was used in jewelry and seals to ward off evil spirits and bring good fortune. This belief was particularly strong when Peridot was set in gold, a combination that was common in Egyptian jewelry. The gemstone’s protective qualities were also valued in religious and spiritual contexts, where it was used in ceremonial jewelry and sacred artifacts.
Modern gemstone enthusiasts and metaphysical practitioners continue to value Peridot for its calming and positive energy. It is often used in meditation and healing practices to promote emotional balance and inner peace. Peridot is believed to help individuals release negative emotions and foster a sense of well-being and harmony.
In addition to its emotional and spiritual properties, Peridot is also associated with prosperity and abundance. It is believed to attract wealth and success, making it a popular choice for those seeking to enhance their financial and professional lives. This association with prosperity is reflected in its historical use as a protective and auspicious gemstone.
Peridot is also linked to the heart chakra, which is associated with love, compassion, and emotional healing. It is believed to help individuals open their hearts to love and foster deeper connections with others. This makes it a popular choice for those seeking to enhance their relationships or heal emotional wounds.
Care and Cleaning
Peridot is a relatively soft gemstone, with a hardness of 6.5 to 7 on the Mohs scale. This makes it more susceptible to scratches and damage compared to harder gemstones like sapphire or ruby. As a result, it is important to take special care when cleaning and handling Peridot to ensure its longevity.
When cleaning Peridot, it is best to use warm, soapy water and a soft cloth or brush. Avoid using harsh chemicals or abrasive cleaners, as these can damage the gemstone’s surface. Ultrasonic and steam cleaners can be used with caution, but it is important to check for any fractures or inclusions that could be exacerbated by these methods.
Peridot is also sensitive to high heat, which can cause some colors to fade. Therefore, it is advisable to avoid exposing Peridot to prolonged periods of direct sunlight or high temperatures. This is especially important for Peridot with a higher concentration of iron, which can be more susceptible to color fading.
When wearing Peridot jewelry, it is best to avoid wearing it during activities that involve heavy contact or impact. This is particularly important for rings, which are more likely to be subjected to wear and tear. Peridot is best suited for jewelry that is worn less frequently, such as pendants or earrings, where it is less likely to be damaged.
Storing Peridot properly is also essential to prevent scratches and damage. It should be stored separately from other gemstones, especially those that are harder on the Mohs scale. A soft pouch or a separate compartment in a jewelry box is ideal for storing Peridot to protect it from scratches and dust.
