History and Lore
Peridot has a long and storied history that spans across different cultures and time periods. Known as "the gem of the sun" in Ancient Egypt, peridot was associated with the sun god Ra and was believed to have been formed from solidified rays of the sun. The Egyptians mined peridot from the island of Zabargad, located in the Red Sea, and used it in jewelry and amulets to ward off evil and promote good health.
In Hawaiian legend, peridot stones were said to be the tears of the goddess Pele, the deity of volcanoes and fire. According to this legend, Pele's tears, shed with sorrow and longing, fell to the earth and crystallized into the green gemstones we know today. This story adds to the mystique of peridot and highlights its connection to the natural world and the elements of fire and earth.
Peridot has also been found in ancient Roman and Greek artifacts, indicating its widespread use and appreciation in the classical world. The Romans believed that peridot had protective powers and used it in jewelry to ward off nightmares and negative energy. In medieval Europe, peridot was often confused with topaz due to its similar color, and it was used in various forms of adornment, including rings, pendants, and brooches.
Today, peridot continues to be a popular gemstone, especially among those born in August. Its historical significance and cultural associations have contributed to its enduring appeal and make it a meaningful choice for those seeking a gemstone with depth and character.
Geological Formation and Sources
Peridot is a gemstone formed through unique geological processes that occur deep within the Earth's mantle. It is a transparent gem variety of the silicate mineral group olivine. Olivine is a group of minerals that includes peridot and other related species. The formation of peridot involves the cooling and solidification of magma, which is rich in magnesium and iron. As the magma cools, these elements combine to form the silicate structure that characterizes peridot.
The most significant sources of peridot are found in a few specific locations around the world. One of the most notable sources is the island of Zabargad in the Red Sea, where peridot has been mined for thousands of years. This island, also known as St. John’s Island, has been a major source of peridot due to its volcanic activity and the presence of basaltic rock formations that are ideal for the formation of this gemstone.
Other significant sources of peridot include the United States, particularly in Arizona and New Mexico, where peridot is often found in volcanic rocks. These regions have become important sources of high-quality peridot, and the gemstone is even considered the state gemstone of Arizona. In addition to these locations, peridot is also mined in countries such as China, Brazil, and Afghanistan.
The rarity of peridot varies depending on its color and size. While peridot is not considered a rare gemstone in general, large, high-quality specimens with vibrant green coloration are relatively scarce. The discovery of blue garnets in the 1990s highlights the ongoing exploration and study of peridot and other gemstones, as new deposits and variations continue to be found.
Gemological Properties
Peridot is a gemstone with distinct gemological properties that set it apart from other stones. One of the key characteristics of peridot is its color, which ranges from a pale yellow-green to a deep olive green. The most desirable and valuable peridot specimens exhibit a vibrant green with a slight yellow tint. This coloration is due to the presence of iron within the mineral structure, which gives peridot its unique hue.
In terms of hardness, peridot has a Mohs hardness rating of 6.5 to 7, making it relatively durable but not as hard as gemstones like diamonds or sapphires. This hardness level means that peridot can be worn in various types of jewelry, but it requires careful handling to avoid scratches and other damage. Peridot also has high double refraction, which means that light passing through the stone can create a doubling effect when viewed through the table of the gemstone.
Peridot has a glassy luster, which contributes to its overall brilliance and visual appeal. This luster is enhanced through proper cutting and polishing techniques, which can bring out the best in the gemstone's color and clarity. Peridot is typically transparent, but it can also be found in translucent or even opaque forms, depending on the specific mineral composition and the presence of inclusions.
The refractive index of peridot ranges from 1.650 to 1.888, which is relatively high and contributes to its brilliance and fire. This refractive index can vary slightly depending on the specific composition of the peridot, as different species within the olivine group can have slightly different refractive properties.
Peridot is also known for its pleochroism, a property that allows the gemstone to display different colors when viewed from different angles. This effect can be subtle but is one of the unique characteristics that make peridot a fascinating gemstone to study and admire.
Symbolism and Metaphysical Beliefs
Peridot has long been associated with various symbolic and metaphysical properties, making it a gemstone of both beauty and meaning. In many cultures, peridot is believed to promote positivity, vitality, and emotional well-being. Its association with the sun and light has led to beliefs that it can bring warmth, joy, and optimism to those who wear it.
In Ancient Egypt, peridot was considered a sacred gemstone and was believed to have protective properties. It was used in amulets and talismans to ward off evil and promote good health. The Egyptians also believed that peridot could help in the treatment of fevers and other illnesses, further adding to its perceived healing properties.
In Hawaiian legend, peridot was believed to be the tears of the goddess Pele, and it was associated with the power of fire and the natural elements. This belief underscores the connection between peridot and the forces of nature, as well as its role as a symbol of transformation and renewal.
Modern metaphysical beliefs continue to attribute positive properties to peridot. It is often used in crystal healing practices to promote emotional balance and to help with stress relief.

In addition to its positive associations with abundance, peridot is also believed to help with the release of negative emotions and to promote a sense of inner peace and harmony.
Care and Cleaning
Proper care and cleaning are essential for maintaining the beauty and longevity of peridot. Due to its relatively low hardness compared to some other gemstones, peridot requires careful handling to avoid scratches and other damage. The following guidelines can help ensure that peridot remains in excellent condition for years to come.
First, it is important to store peridot away from harder gemstones to prevent scratches. Peridot can be scratched by gemstones with a higher Mohs hardness rating, such as diamonds, sapphires, and rubies. It is best to store peridot separately or in a soft-lined jewelry box to protect it from contact with other stones.
When it comes to cleaning peridot, it is best to use a gentle method that does not involve harsh chemicals or excessive heat. A mild soap solution and a soft cloth or brush can be used to clean peridot jewelry. Avoid using ultrasonic cleaners or steam cleaners, as these can potentially damage the gemstone or loosen any settings.
Peridot should also be protected from exposure to heat and extreme temperature changes. Sudden temperature fluctuations can cause the gemstone to crack or become damaged. It is best to avoid wearing peridot in environments where it may be exposed to high heat, such as near a stove or in a sauna.
When wearing peridot jewelry, it is important to be mindful of activities that may cause damage. Avoid wearing peridot during activities that involve heavy physical contact or exposure to abrasive materials. This will help prevent scratches and other forms of wear.
Regular inspection of peridot jewelry is also recommended to ensure that the gemstone remains securely set and that the setting is in good condition. If any signs of wear or damage are noticed, it is best to have the jewelry inspected by a professional jeweler to prevent further issues.
