History and Lore
Peridot’s history is as rich and colorful as its appearance. This gemstone has been cherished for millennia, with evidence of its use in ancient civilizations across the world. The earliest known use of Peridot dates back to the ancient Egyptians, who called it the “gem of the sun” and believed it to be a gift from the gods. The Egyptians mined Peridot from the island of St. John’s in the Red Sea, which was later renamed Topazios, a name often confused with the gemstone topaz.
Throughout history, Peridot has often been mistaken for other green gemstones such as emerald and topaz. This confusion was particularly common during the medieval period in Europe, where many "emeralds" in cathedral treasures have since been identified as Peridot. For example, the Shrine of the Three Holy Kings in Cologne Cathedral is adorned with Peridot, originally believed to be emeralds.
Peridot is also associated with the zodiac sign of Leo, the fifth sign of the zodiac, which is ruled by the Sun. Those born under the sign of Leo, particularly those born on August 22, are said to benefit from Peridot’s symbolic properties of growth, renewal, and positive energy. In ancient cultures, Peridot was believed to offer protection from nightmares and to promote good health and prosperity.
The gemstone has also found its way into various cultural and spiritual traditions. In medieval Europe, Peridot was considered a protective stone and was often worn to ward off evil spirits and negative energies. It was also believed to have healing properties and was used in the treatment of various ailments. In some cultures, Peridot was thought to bring happiness and prosperity, making it a popular choice for gifts and jewelry.
Peridot’s name is believed to have originated from the Arabic word “faridat,” meaning gem. This etymology highlights the stone’s long-standing association with beauty and value. The name “peridot” was first recorded in English in the early 19th century, and it has since become the widely accepted term for the gemstone.
In addition to its historical and cultural significance, Peridot has a unique geological origin that contributes to its rarity and allure. The gemstone is formed under extreme conditions, often found in the hardened lava that carried it from deep within the Earth’s mantle. It can also be found in meteorites that have traveled from outer space, making Peridot a truly cosmic gemstone.
Geological Formation and Sources
Peridot is a gem-quality variety of the mineral olivine, which is a magnesium iron silicate. Its distinctive green color is due to the presence of iron in its chemical composition. The color can vary from a yellowish-green to a deep olive-green, depending on the concentration of iron. Peridot is transparent to translucent and has a vitreous luster, making it highly desirable for jewelry.
The formation of Peridot occurs under high-pressure and high-temperature conditions, typically in the Earth’s mantle. It is often found in igneous rocks, particularly in basaltic lava flows and in meteorites. The gemstone can also be found in metamorphic rocks, where it is formed through the transformation of other minerals under intense heat and pressure. This unique formation process gives Peridot its distinct properties and makes it a valuable and sought-after gemstone.
Peridot is primarily found in several locations around the world. One of the most well-known sources is the island of St. John’s in the Red Sea, where ancient Egyptians mined Peridot from basaltic lava flows. Other notable sources include Arizona in the United States, where Peridot is found in volcanic rock, and Myanmar, where it is mined alongside other gemstones such as ruby and sapphire.
In recent years, Peridot has also been discovered in other locations, including Brazil, China, and Pakistan. These new sources have contributed to the availability of Peridot in the global market, making it more accessible to jewelry designers and collectors. Despite its widespread availability, Peridot remains a relatively rare gemstone, particularly in larger sizes and high-quality grades.
The presence of Peridot in meteorites adds to its mystique and scientific interest. These extraterrestrial sources of Peridot are found in chondritic meteorites, which are some of the oldest materials in the solar system. The study of Peridot in meteorites has provided valuable insights into the formation of the Earth and other planetary bodies.
Gemological Properties
Peridot is a unique gemstone with a range of distinctive gemological properties that make it highly valued in the world of gemology. One of its most notable characteristics is its color, which is caused by the presence of iron in its chemical composition. The color can vary from a yellowish-green to a deep olive-green, depending on the concentration of iron. This variation in color allows for a wide range of aesthetic possibilities in jewelry design.
Peridot has a hardness of 6.5 to 7 on the Mohs scale, which makes it relatively durable but not as hard as gemstones like diamonds, sapphires, or rubies. This hardness level means that Peridot is suitable for use in jewelry but requires careful handling to prevent scratches and other damage. It is also important to note that Peridot has a perfect cleavage in one direction, which can make it more susceptible to chipping if struck at an angle.
In terms of refractive index, Peridot has a range of 1.650 to 1.690, which gives it a moderate level of brilliance and fire. The gemstone is singly refractive, meaning it does not exhibit double refraction like some other gemstones. Peridot has a specific gravity of 3.30 to 4.35, which is relatively high compared to other gemstones. This high specific gravity contributes to the gemstone’s weight and density.
Peridot is transparent to translucent and has a vitreous luster, which enhances its visual appeal. It is often cut in a variety of shapes, including round, oval, and emerald cuts, to maximize its brilliance and color. The most valuable Peridots are those that are large in size, have a deep olive-green color, and are free of inclusions and other imperfections.
The gemstone is also known for its pleochroism, meaning it can display different colors when viewed from different angles. This property is particularly noticeable in Peridot with a high concentration of iron, which can appear to have a different color in different lighting conditions. This characteristic adds to the gemstone’s allure and makes it a popular choice for collectors and jewelry enthusiasts.
Peridot is not typically treated or enhanced, as its natural properties are already highly desirable. However, some lower-quality Peridots may be heat-treated to improve their color and clarity. These treatments are generally stable and do not affect the gemstone’s durability or appearance.
Symbolism and Metaphysical Beliefs
Peridot is not only valued for its aesthetic appeal and gemological properties but also for its rich symbolism and metaphysical beliefs. Across different cultures and eras, Peridot has been associated with a wide range of meanings and powers. In ancient Egypt, it was considered a protective stone and was often used in amulets and talismans to ward off evil spirits and negative energies. It was also believed to promote good health and prosperity, making it a popular choice for gifts and jewelry.
In medieval Europe, Peridot was considered a protective stone and was often worn to ward off nightmares and promote peaceful sleep. It was also believed to have healing properties and was used in the treatment of various ailments. The gemstone was associated with the Sun and was believed to bring positive energy and vitality to those who wore it.
In modern times, Peridot is often associated with the Heart Chakra, making it a popular choice for those seeking emotional healing and balance. It is believed to promote compassion, love, and forgiveness, making it a powerful tool for emotional and spiritual growth. Peridot is also associated with the zodiac sign of Leo, the fifth sign of the zodiac, and is believed to enhance the natural qualities of Leos, such as confidence, creativity, and leadership.

It is also thought to help release negative patterns and emotions, making it a powerful tool for personal transformation. Peridot is also associated with the Sun and is believed to bring warmth, light, and positivity into one’s life.
Care and Cleaning
Due to its relatively low hardness and perfect cleavage in one direction, Peridot requires careful handling and cleaning to maintain its beauty and durability. The gemstone should be protected from scratches and impacts, as it can be easily damaged if struck at an angle. It is also important to avoid exposing Peridot to extreme temperatures, as this can cause it to crack or lose its luster.
When it comes to cleaning Peridot, it is best to use a soft cloth and mild soap and water. Harsh chemicals or abrasive cleaners should be avoided, as they can damage the gemstone’s surface and reduce its brilliance. It is also important to avoid using ultrasonic cleaners or steam cleaners, as these can cause the gemstone to become brittle or cracked.
Peridot should be stored separately from other gemstones to prevent scratches and damage. It is best to store it in a soft pouch or a jewelry box with individual compartments. This will help to protect it from dust, moisture, and other environmental factors that can affect its appearance and longevity.
When wearing Peridot jewelry, it is important to be mindful of the activities you are doing. It is best to avoid wearing Peridot jewelry during activities that involve heavy lifting, construction, or other tasks that could expose the gemstone to impact or damage. It is also best to remove Peridot jewelry before swimming or showering, as chlorine and other chemicals can damage the gemstone’s surface.
Regular inspection of Peridot jewelry is also recommended to ensure that it is in good condition. Any signs of wear, damage, or discoloration should be addressed promptly by a professional jeweler. With proper care and maintenance, Peridot can retain its beauty and value for generations to come.
