History and Lore
Peridot has a long and storied history that spans across cultures and centuries. Known to ancient civilizations, the gemstone was revered not only for its beauty but also for its perceived magical properties. In ancient Egypt, peridot was considered a sacred stone, often referred to as the "gem of the sun." It was believed to bring protection against nightmares and to provide the wearer with a sense of peace and calm. This belief was particularly important in a time when superstitions and spiritual practices were deeply intertwined with daily life.
The gemstone’s historical significance is further underscored by its association with various myths and legends. For instance, peridot was once thought to be a fallen star. This belief was rooted in the gem’s vivid green color, which was said to resemble the glow of a star. In some cultures, peridot was also associated with the Sun, reflecting its luminous and energetic qualities. The gemstone’s connection to light and energy made it a symbol of renewal and vitality.
In the Middle Ages, peridot was often used in religious and ceremonial contexts. It was believed to have protective qualities, and many people wore it as a talisman to ward off evil spirits. The gemstone was also associated with the Virgin Mary, and it was said to have been used in the construction of the crown of thorns. These associations further cemented peridot’s place in history as a stone of spiritual significance.
The modern designation of peridot as the August birthstone began in the 20th century. In 1912, the American National Association of Jewelers officially recognized peridot as the birthstone for August. This decision was influenced by the gemstone’s widespread use in jewelry and its appealing color, which resonates with the lush greenery of the summer months. The designation of peridot as a birthstone has since become a cherished tradition, with many people choosing to celebrate their August birthdays with this beautiful gemstone.
Geological Formation and Sources
Peridot is a variety of the mineral olivine, a group of minerals that are typically found in igneous rocks. The gemstone forms in the Earth's mantle and is brought to the surface through volcanic activity. Peridot is most commonly found in volcanic rocks such as basalt and in meteorites. This unique formation process contributes to the gemstone’s distinct properties and appearance.
The green color of peridot is due to the presence of iron within its chemical composition. The more iron a peridot contains, the deeper its green hue. The gemstone’s color can range from a light olive green to a rich, vibrant green, making it a versatile choice for jewelry. Peridot is also known for its glassy luster, which enhances its beauty and makes it highly desirable in the jewelry industry.
Peridot is found in various parts of the world, with significant deposits located in countries such as the United States, Brazil, China, and Pakistan. The gemstone is particularly abundant in Arizona, where it is mined from the San Carlos Apache Reservation. This location is known for producing high-quality peridot with a consistent color and clarity. Other notable sources include Myanmar, which is famous for producing some of the finest peridot in the world, and India, where peridot is also found in various geological formations.
In addition to natural sources, peridot can also be synthesized in laboratories. This process allows for the creation of gemstones that are chemically identical to their natural counterparts but are more affordable and ethically sourced. The availability of lab-grown peridot has made it possible for a wider audience to enjoy the beauty of this gemstone without the environmental and ethical concerns associated with mining.
Gemological Properties
Peridot is a unique gemstone with a set of distinct gemological properties that contribute to its appeal and value. One of the most notable characteristics of peridot is its color. The gemstone is known for its range of green hues, which are caused by the presence of iron in its chemical composition. This coloration is what makes peridot stand out and is a key factor in its popularity as a birthstone.
The gemstone’s chemical formula is (Mg,Fe)₂SiO₄, and it is part of the nesosilicate class of minerals. Peridot has a hardness of 6.5 to 7 on the Mohs scale, making it relatively durable but still requiring careful handling to avoid scratches and damage. Its refractive index ranges from 1.65 to 1.70, which contributes to its brilliance and luster when properly cut and polished.
Peridot is also known for its inclusions, which are often visible to the naked eye. These inclusions, commonly referred to as "花园效应" (garden effect), can include tiny crystals of other minerals or small gas bubbles. While these inclusions can affect the gemstone’s clarity, they are often considered part of its charm and character, especially in higher-quality stones where the inclusions are subtle and do to detract from the overall appearance.
The gemstone is typically cut into a variety of shapes, including round, oval, and emerald cuts, to enhance its color and brilliance. The most popular cut for peridot is the round brilliant cut, which maximizes the gemstone’s sparkle and makes it an excellent choice for engagement rings and other fine jewelry pieces.
Peridot is also known for its transparency, which can range from transparent to translucent. The most valuable and sought-after peridots are those that are transparent with minimal inclusions. These stones are often used in high-end jewelry and are prized for their clarity and color.
In terms of carat weight, peridot is available in a wide range of sizes, from small melee stones to large, statement pieces. The price of peridot can vary depending on its size, color, and clarity. Stones with a deeper, more intense green color and higher clarity tend to command higher prices, making them particularly desirable in the jewelry market.
Symbolism and Metaphysical Beliefs
Peridot has been associated with a wide range of symbolic meanings and metaphysical properties across different cultures and historical periods. In ancient times, it was believed to have protective qualities and was often used as a talisman to ward off evil spirits and nightmares. This belief was particularly important in a time when superstitions and spiritual practices were deeply intertwined with daily life. The gemstone was also associated with the Sun, reflecting its luminous and energetic qualities. The connection to the Sun made peridot a symbol of renewal and vitality.
In addition to its protective qualities, peridot was also believed to have healing properties. It was thought to promote physical and emotional healing, helping to restore balance and harmony to the body and mind. This belief in peridot’s healing powers has persisted into modern times, with many people using it in alternative medicine and spiritual practices. The gemstone is often used in crystal healing, where it is believed to help with stress relief, emotional balance, and overall well-being.
Peridot is also associated with love and friendship. In many cultures, it is believed to promote positive emotions and to strengthen bonds between people.

Care and Cleaning
Proper care and cleaning are essential to maintaining the beauty and longevity of peridot. Due to its relatively low hardness on the Mohs scale (6.5 to 7), peridot requires careful handling to avoid scratches and damage. The gemstone is also sensitive to heat and sudden temperature changes, so it is important to avoid exposing it to extreme conditions.
When cleaning peridot, it is recommended to use a mild soap and warm water. A soft cloth or a soft-bristled brush can be used to gently clean the surface of the gemstone. It is important to avoid using harsh chemicals or abrasive materials, as these can damage the gemstone’s surface and reduce its luster. Ultrasonic cleaners can be used with caution, but it is important to ensure that the gemstone is free of any inclusions or fractures that could be worsened by the vibrations.
Peridot should be stored separately from other gemstones to prevent scratches. It is best to store it in a soft pouch or a lined jewelry box to protect it from dust and physical contact. When not in use, peridot should be kept in a cool, dry place to avoid exposure to excessive heat or humidity, which can cause the gemstone to lose its color and luster.
In addition to regular cleaning and storage, it is also important to have peridot inspected by a professional jeweler on a regular basis. A professional can check for any signs of wear or damage and can provide advice on how to maintain the gemstone’s beauty and value over time. This is particularly important for peridot jewelry, as the settings and other components can also be affected by wear and tear.
