Peridot, the vibrant green gemstone recognized as the primary birthstone for August, carries a rich legacy of historical significance, geological intrigue, and symbolic meaning.

This article delves into the multifaceted nature of peridot, exploring its geological formation, historical uses, cultural symbolism, and practical considerations for care and appreciation.
Peridot is not the only gemstone associated with August. The month also includes sardonyx and spinel as official birthstones. However, peridot stands out as the most widely recognized and celebrated of the three. Its vivid green hue, caused by the presence of iron in its composition, makes it a unique and eye-catching gemstone. This article will focus on peridot, while briefly acknowledging the other August birthstones when relevant.
The significance of peridot extends beyond its aesthetic appeal. It has been revered across various cultures and time periods for its supposed protective properties and its association with positivity and abundance. Modern gemology has confirmed some of these historical beliefs, while also providing a scientific understanding of peridot’s composition and characteristics.
History and Lore
Peridot has a long and storied history, with evidence of its use dating back to ancient civilizations. The ancient Egyptians referred to peridot as the "Gem of the Sun," believing it to be formed from solidified sunlight. They mined peridot on the island of Zabargad (St. John’s Island) in the Red Sea and used it in jewelry and amulets for protection and good fortune.
In medieval Europe, peridot was often confused with emerald due to its similar green color. However, peridot is more affordable and has a distinct composition. During the Renaissance, it was popular among European nobility, particularly in Bohemia, where it was often cut in the traditional "Bohemian cut" to enhance its brilliance.
Peridot’s association with the sun and its vibrant green hue have contributed to its symbolism of renewal, vitality, and positivity. In some cultures, it is believed to bring good health and ward off negative energies. The gemstone was also traditionally used as a 16th wedding anniversary gift, symbolizing enduring love and harmony.
In modern times, peridot has gained popularity as an August birthstone. While it has historical roots in various cultures, its designation as an official birthstone is relatively recent. The American National Association of Jewelers recognized peridot as the August birthstone in the 1920s, and it has since become a widely accepted symbol for those born in this month.
Geological Formation and Sources
Peridot is a type of olivine, a group of minerals composed of magnesium and iron silicates. Its chemical formula is (Mg, Fe)₂SiO₄, with the iron content determining the intensity of its green color. The higher the iron content, the deeper the green hue.
The gemstone is formed in the Earth's mantle and brought to the surface through volcanic activity. It can also be found in meteorites, making it one of the few gemstones that can be traced back to outer space. Peridot deposits are found in various parts of the world, including:
- United States: Arizona is a well-known source of high-quality peridot, particularly in the San Carlos Apache Reservation.
- Zimbabwe: Zimbabwe produces some of the finest peridot in the world, known for its intense green color.
- Egypt: The original source of peridot, where it has been mined for thousands of years.
- India and Pakistan: These countries also have significant peridot deposits, producing gemstones of varying quality.
Peridot is typically found in basaltic lava flows and in metamorphic rocks. Its formation process involves the cooling of molten rock and the subsequent crystallization of the olivine minerals. The presence of iron in the composition gives peridot its characteristic green color.
Gemological Properties
Peridot is a relatively soft gemstone compared to other popular birthstones, but it is durable enough for everyday wear. Below are the key gemological properties of peridot:
- Hardness: 6.5 to 7 on the Mohs scale
- Refractive Index: 1.65 to 1.70
- Color: Yellow-green to olive-green, depending on iron content
- Transparency: Usually transparent to translucent
- Luster: Vitreous (glassy)
- Cleavage: Perfect in one direction
- Specific Gravity: 3.32 to 3.37
Peridot is known for its vivid color, which remains consistent under different lighting conditions. Unlike some gemstones that change color under artificial light, peridot maintains its green hue, making it a reliable and desirable choice for jewelry.
The gemstone is typically cut in a brilliant or mixed cut to enhance its fire and sparkle. It can be found in a variety of shapes, including round, oval, and princess cuts. Peridot is often set in yellow gold, white gold, or silver to complement its warm green tones.
While peridot is not as rare as some other gemstones, high-quality peridot with a deep green color and good clarity can be relatively uncommon. This makes it a valuable and collectible gemstone, particularly in larger sizes.
Symbolism and Metaphysical Beliefs
Peridot has long been associated with positive energy and protective qualities. In ancient times, it was believed to bring courage, strength, and protection against nightmares and negative energies. The gemstone was also thought to promote emotional healing and to enhance feelings of love and compassion.
In modern metaphysical practices, peridot is considered a stone of transformation and renewal. It is believed to help release old patterns and emotions, making it useful for those undergoing personal change or seeking to overcome challenges. Peridot is also associated with the heart chakra and is thought to promote feelings of joy, optimism, and inner peace.
Some sources suggest that peridot has healing properties, particularly for the liver and gallbladder. It is also believed to improve adrenaline function and support overall vitality. While these claims are not scientifically proven, many people find comfort in the symbolic and metaphysical associations of peridot.
In jewelry, peridot is often used in rings, necklaces, and earrings. It is especially popular in engagement rings and wedding bands as a symbol of enduring love and positivity. Its affordability and beauty make it an excellent choice for those looking for a meaningful and stylish piece of jewelry.
Care and Cleaning
Due to its relatively soft nature, peridot requires careful handling and cleaning to maintain its beauty and longevity. Below are some guidelines for caring for peridot jewelry:
- Avoid Harsh Chemicals: Peridot should not be cleaned with harsh chemicals or ultrasonic cleaners, as this can damage the gemstone. Instead, use a soft cloth and mild soap to gently clean the surface.
- Avoid Heat: Exposure to high temperatures can cause peridot to lose its color or become brittle. Avoid leaving peridot jewelry in direct sunlight or near heat sources for extended periods.
- Store Properly: To prevent scratches and damage, store peridot jewelry in a soft pouch or a separate compartment. Avoid storing it with other gemstones that may scratch its surface.
- Avoid Impact: Peridot has perfect cleavage in one direction, making it susceptible to chipping if struck hard. Avoid wearing peridot jewelry during activities that may expose it to impact.
With proper care, peridot can maintain its vibrant color and brilliance for many years. It is a durable gemstone for everyday wear, but it should be handled with care to preserve its beauty.
