It has been treasured for its beauty and symbolic meanings, often associated with prosperity, healing, and protection. As the birthstone for August 15th, peridot has a unique place in both historical and contemporary gemology. This article will delve into the history and lore of peridot, its geological formation, gemological characteristics, and the metaphysical beliefs surrounding it.

History and Lore
Peridot has a long and storied history, with evidence of its use in ancient civilizations. The gemstone was highly valued in Egypt, where it was often incorporated into jewelry and religious artifacts. In fact, many "emeralds" found in medieval European cathedral treasures have been identified as peridots. This misidentification highlights the gemstone's striking resemblance to emeralds, despite their different chemical compositions and origins.
One of the most notable historical associations with peridot is its connection to the Red Sea island of Topazios, which was once believed to be a source of topaz. In reality, the island produced peridot, which may have contributed to the confusion between the two gemstones. The name "peridot" is believed to derive from the Arabic word "faridat," meaning gem. This etymology reflects the gemstone's significance in Middle Eastern cultures, where it was often used in jewelry and religious ceremonies.
Throughout history, peridot was thought to possess mystical and protective properties. Ancient civilizations believed that peridot could ward off evil spirits and bring its wearer good fortune. In medieval Europe, peridot was considered a stone of protection and was often used in talismans and amulets. These beliefs have persisted into modern times, where peridot is still associated with prosperity and abundance.
Geological Formation and Sources
Peridot is a gem-quality variety of the mineral olivine, which is formed under extreme geological conditions. It is typically found in the hardened lava that carries it from deep within the Earth's mantle to the surface. This process involves high temperatures and pressures, which are essential for the formation of olivine. In addition to volcanic activity, peridot can also be found in meteorites, which have traveled from outer space to Earth.
The primary sources of peridot include the United States, Egypt, and Pakistan. In the United States, peridot is notably found in Arizona, where it is mined from volcanic rocks. Egypt has been a significant source of peridot for centuries, with historical evidence of its use in ancient Egyptian jewelry. The gemstone is also found in other parts of the world, including Brazil and China, where it is mined and used in various types of jewelry and decorative items.
The unique geological conditions required for peridot formation contribute to its rarity and value. The gemstone's vibrant color is due to the presence of iron within its chemical structure. This iron content not only gives peridot its distinctive green color but also influences the varying shades of green that can be observed in different specimens.
Gemological Properties
Peridot possesses a range of gemological properties that make it a desirable gemstone for jewelry. It is known for its hardness on the Mohs scale, which measures the hardness of minerals. Peridot has a hardness of 6.5 to 7, making it relatively durable for a gemstone, though it is still softer than many other popular gemstones like diamonds or sapphires. This hardness level means that peridot is suitable for use in rings and other jewelry pieces, but it requires careful handling to avoid scratches or chips.
The refractive index of peridot ranges from 1.650 to 1.690, which contributes to its brilliance and sparkle. The gemstone's luster is typically vitreous, giving it a glassy appearance that enhances its beauty. Peridot is also known for its pleochroism, which means that it can display different colors when viewed from different angles. This optical phenomenon adds to the gemstone's allure and makes each peridot unique.
In terms of clarity, peridot is generally transparent to translucent, with inclusions that are often visible to the naked eye. These inclusions can include small crystals or other minerals trapped within the gemstone during its formation. While some inclusions may affect the gemstone's clarity, they are often considered part of peridot's charm and character.
The carat weight of peridot can vary significantly, with some specimens weighing just a few carats and others reaching much larger sizes. Larger peridots are rarer and more valuable, especially if they exhibit a deep, vibrant green color. The gemstone's color is graded based on its intensity and purity, with the most desirable peridots displaying a rich, saturated green without any brownish or yellowish tints.
Symbolism and Metaphysical Beliefs
Peridot has long been associated with various symbolic meanings and metaphysical properties. In ancient cultures, it was believed to bring protection and good fortune to its wearer. The gemstone was thought to ward off evil spirits and promote a sense of peace and harmony. These beliefs have persisted into modern times, where peridot is often used in spiritual practices and as a symbol of prosperity and abundance.
In contemporary metaphysical practices, peridot is considered a stone of transformation and healing. It is believed to help release negative emotions and promote a sense of inner peace and clarity. Many people use peridot in meditation practices to enhance their spiritual connection and to encourage a positive outlook. The gemstone is also associated with the heart chakra, which is believed to be the center of love, compassion, and emotional healing.
Peridot is also thought to have a calming effect on the mind and body, making it an excellent stone for those seeking to reduce stress and anxiety. It is believed to encourage a sense of balance and harmony, both within oneself and in relationships with others. As a result, peridot is often used in jewelry and decorative items to create a sense of calm and serenity in the home or workplace.
In addition to its spiritual properties, peridot is also associated with physical healing. It is believed to have a positive effect on the immune system and to promote overall health and vitality. Some people use peridot in crystal healing practices to address various health issues, including digestive problems and skin conditions. While these beliefs are not supported by scientific evidence, many individuals find comfort and reassurance in the use of peridot as a healing stone.
Care and Cleaning
To ensure the longevity and beauty of peridot, it is essential to care for it properly. Due to its relatively low hardness on the Mohs scale, peridot should be handled with care to avoid scratches or chips. It is recommended to store peridot jewelry separately from other gemstones to prevent damage.
Cleaning peridot can be done using a soft cloth and mild soap. A gentle solution of warm water and a mild detergent can be used to clean the gemstone. It is important to avoid using harsh chemicals or abrasive materials, as these can damage the gemstone's surface. After cleaning, peridot should be rinsed thoroughly and dried with a soft cloth to prevent water spots.
When wearing peridot jewelry, it is advisable to avoid exposing the gemstone to harsh chemicals, such as household cleaners or cosmetics. These substances can dull the gemstone's luster and affect its appearance. Additionally, peridot should not be exposed to extreme temperatures or sudden temperature changes, as this can cause it to crack or become brittle.
For those who wear peridot jewelry regularly, it is a good idea to have it inspected by a professional jeweler periodically. A jeweler can check for any signs of wear or damage and provide advice on how to maintain the gemstone's beauty and integrity. Regular inspections can help ensure that peridot jewelry remains in excellent condition for years to come.
