Peridot has a long and storied history, with its use and recognition dating back thousands of years. The gemstone has been found in archaeological sites from ancient Egypt to medieval Europe, where it was prized for its striking green color and its associations with positive energy and protection. The name "peridot" is believed to derive from the Arabic word "faridat," meaning "gem," which reflects the high esteem in which it was held in early civilizations. Throughout history, peridot was often mistaken for other green gemstones, particularly emerald. Many so-called emeralds in medieval European cathedral treasures were, in fact, peridots.
In ancient Egypt, peridot was highly valued and was often worn by the pharaohs. The gemstone was found on the island of Zabargad, also known as St. John's Island, in the Red Sea. The Egyptians called the island "Topazios," a name later applied to the topaz gemstone. The island was a significant source of peridot, and the gemstone was used in jewelry and religious artifacts. The ancient Egyptians believed that peridot had protective properties and could ward off evil spirits.
In ancient Greece and Rome, peridot was associated with the sun and was believed to bring good fortune and vitality to the wearer. The gemstone was also thought to have healing properties and was used in various forms of traditional medicine. During the Middle Ages, peridot was considered a sacred gemstone and was often used in church altars and clergy vestments. In some European traditions, peridot was believed to protect against nightmares and bring peace and calm to the wearer.
The gemstone's association with the sun and its vibrant green color have made it a symbol of renewal and growth in many cultures. In some traditions, peridot was believed to promote positive energy and was used in rituals and ceremonies to encourage prosperity and good fortune. The gemstone's historical significance and cultural symbolism make it a cherished and meaningful birthstone for those born on August 28th.
Geological Formation and Sources
Peridot is a variety of the mineral olivine and is one of the few gemstones that occur in only one color: green. This unique characteristic is due to the presence of iron in the crystal structure. The gemstone forms in volcanic rocks and is often found in areas with a history of volcanic activity. Peridot is typically found in the form of crystals and is known for its glassy luster and vibrant color.
The primary sources of peridot include Egypt, the United States, and other regions with suitable geological conditions. In Egypt, peridot has been mined for centuries on the island of Zabargad, also known as St. John's Island, in the Red Sea. The island is one of the most well-known sources of peridot and has a long history of gemstone mining. The gemstone is also found in the United States, particularly in Arizona and Hawaii, where it is mined in volcanic rocks. Other sources of peridot include China, Brazil, and various other locations around the world.
The formation of peridot is closely linked to volcanic activity. The gemstone is formed when magma cools and solidifies, allowing the crystals to grow. The presence of iron in the magma is essential for the development of the gemstone's characteristic green color. The cooling process must occur slowly to allow the crystals to grow to a sufficient size for gemstone use. This geological process results in the formation of peridot crystals that are typically found in igneous rocks.
The availability of peridot from multiple sources ensures that the gemstone remains accessible to gemstone collectors and jewelry designers. The gemstone's geological properties, including its formation in volcanic rocks and its chemical composition, contribute to its unique characteristics and appeal. The presence of iron in the crystal structure is responsible for the gemstone's vibrant green color, which ranges from a light olive to a deeper, more intense hue.
Gemological Properties
Peridot is a gemstone with distinct gemological properties that make it a popular choice for jewelry and other decorative uses. The gemstone is known for its vibrant green color, which is caused by the presence of iron in the crystal structure. The color of peridot can range from a light olive green to a deeper, more intense green, depending on the concentration of iron in the crystal. This variation in color adds to the gemstone's appeal and makes it a versatile choice for jewelry.
The hardness of peridot on the Mohs scale is between 6.5 and 7, making it relatively durable but still requiring careful handling. The gemstone is also known for its vitreous luster, which gives it a glassy appearance. Peridot has a refractive index of 1.65 to 1.69, which contributes to its brilliance and sparkle when cut and polished. The gemstone is also known for its relatively low dispersion, which means that it does not exhibit the same level of fire as diamonds or other high-dispersion gemstones.
Peridot is typically cut into a variety of shapes, including round, oval, and emerald cuts, to enhance its natural beauty and maximize its brilliance. The gemstone is also known for its inclusions, which are often visible under magnification. These inclusions are a natural characteristic of peridot and can add to the gemstone's charm and uniqueness. However, excessive inclusions can affect the clarity and overall appearance of the gemstone.
The chemical composition of peridot is (Mg, Fe)₂SiO₄, with the presence of iron being responsible for its green color. The gemstone is also known for its specific gravity, which ranges from 3.30 to 3.37, making it a relatively heavy gemstone for its size. These gemological properties contribute to the unique characteristics and appeal of peridot, making it a popular choice for jewelry and other decorative uses.
Symbolism and Metaphysical Beliefs
Peridot has long been associated with various symbolic meanings and metaphysical beliefs across different cultures and eras. The gemstone is often considered a symbol of renewal, growth, and prosperity, making it a meaningful choice for those seeking to embrace new beginnings and positive change.

Care and Cleaning
Peridot is a relatively durable gemstone, but it requires proper care and maintenance to ensure its longevity and beauty. The gemstone has a hardness of 6.5 to 7 on the Mohs scale, which means that it is susceptible to scratches and abrasions if not handled carefully. Peridot is also known for its inclusions, which can make it more fragile in certain areas. To maintain the gemstone's appearance and prevent damage, it is important to follow proper care and cleaning practices.
When cleaning peridot, it is recommended to use a soft cloth and mild soap and water. The gemstone should be gently wiped to remove any dirt or debris.

Ultrasonic cleaners can be used for peridot, but it is important to ensure that the gemstone does not have any inclusions that could be affected by the vibrations. Steam cleaning is generally not recommended for peridot due to its potential to cause damage.
To prevent scratches and abrasions, peridot should be stored separately from other gemstones and jewelry. The gemstone should be placed in a soft pouch or a lined jewelry box to prevent contact with other hard surfaces. When wearing peridot jewelry, it is important to avoid activities that could cause impact or pressure on the gemstone, as this can lead to chipping or cracking. Peridot should also be removed before engaging in activities such as swimming, exercising, or using household chemicals, as these can cause damage to the gemstone.
Regular inspection of peridot jewelry is recommended to ensure that the gemstone remains secure and in good condition.
