The vibrant, olive-green hue of the peridot has been cherished for millennia, earning its place as one of the most distinctive and beloved gemstones. As the primary birthstone for the month of August, it symbolizes strength, protection, and harmony. Its color, reminiscent of late-summer foliage and the golden light of the sun, makes it a captivating choice for jewelry, from minimalist stud earrings to intricate vintage settings. This article explores the rich history, geological origins, gemological properties, and cultural symbolism of the peridot, drawing upon its documented significance in both ancient lore and modern jewelry design.
History and Lore
The history of the peridot is as ancient and colorful as the gem itself. It has been a source of fascination for various cultures, which imbued it with powerful meanings and protective qualities. According to historical accounts, the peridot was revered by ancient cultures as a gem of protection and renewal. Its luminous green hue was often associated with the sun, leading to beliefs that it could dispel darkness and fear. The gemstone's connection to the sun is a recurring theme, with ancient civilizations believing that the peridot was a gift from Mother Nature to celebrate the birth of a new year. This association with light and the sun led to its use in talismans and amulets designed to ward off evil spirits and protect the wearer during the night.
The journey of the peridot to its modern status as a birthstone is a testament to its enduring appeal. While its recognition as August's primary gem is well-established, its lore extends to specific relationships and personality traits. Some sources attribute the gemstone to fostering harmony in relationships, making it a meaningful gift for loved ones. This symbolism is often linked to the zodiac signs of Leo (July 23 - August 22) and Virgo (August 23 - September 22), suggesting that those born under these signs may be particularly aligned with the stone's harmonious energy.
Geological Formation and Sources
Peridot is unique among gemstones for being one of the few that is found in only one color. Its distinct olive to lime-green hue is a direct result of its chemical composition. The gem is a variety of the mineral olivine, which is formed deep within the Earth's mantle. It is brought to the surface through volcanic activity, and in some cases, can also be found in meteorites that have fallen to Earth, a rare occurrence that adds to its mystique.
While the provided sources do not specify the exact modern mining locations, they highlight the gem's historical sources. Ancient Egyptians were among the first to mine peridot, sourcing it from the island of Zabargad in the Red Sea. This location was a significant source for many centuries, and the gems mined there were highly prized. The peridot from these ancient sources is often characterized by its rich, saturated color.
The formation of peridot requires specific geological conditions. It crystallizes from magma that is rich in magnesium and silica. As this magma cools, olivine crystals form. These crystals are then brought to the surface by tectonic activity or volcanic eruptions. The gem's presence in volcanic rocks is a key indicator of its origin. The process of bringing these gems from the mantle to the surface is a violent one, yet the resulting crystals are often found in a state of remarkable clarity and beauty.
Gemological Properties
Understanding the gemological properties of peridot is essential for both jewelers and collectors. Its physical characteristics determine its durability, brilliance, and overall value. While the provided sources focus on the gem's symbolic and aesthetic qualities, general gemological knowledge provides a comprehensive picture.
Color: The most defining characteristic of peridot is its color. It ranges from a light, yellowish-green to a deep, olive green. The ideal color is often described as a vibrant, pure green without any brownish tints. The color is caused by the presence of iron within its chemical structure.
Hardness and Durability: On the Mohs scale of hardness, peridot ranks between 6.5 and 7. This makes it a relatively durable gemstone, suitable for everyday wear in jewelry such as rings, earrings, and pendants. However, its hardness is lower than that of sapphire or diamond, and it can be susceptible to scratching if not handled with care.
Chemical Composition: Peridot is the gem-quality variety of olivine, with a chemical formula of (Mg, Fe)₂SiO₄. The ratio of magnesium to iron determines the specific shade of green.
Clarity and Cut: Peridot is often found with good clarity, though it can contain inclusions known as "lily pads" – small, disc-shaped liquid inclusions. These inclusions are a natural part of the gem and can sometimes be used to identify it. The gem is cut into a variety of shapes to maximize its brilliance, with popular cuts including round, oval, and the distinctive Asscher cut, which is a square shape with step-cut facets.
The following table summarizes key gemological data for peridot:
| Property | Description |
|---|---|
| Mineral | Olivine |
| Chemical Formula | (Mg, Fe)₂SiO₄ |
| Color | Olive green, yellowish-green |
| Mohs Hardness | 6.5 - 7 |
| Crystal System | Orthorhombic |

Symbolism and Metaphysical Beliefs
The symbolism attached to the peridot is multifaceted, encompassing themes of protection, prosperity, and emotional balance. In ancient times, it was considered a powerful amulet against evil and was often set in gold and worn on the left arm for maximum protective effect. This belief in its protective power has persisted through the ages.
In modern metaphysical circles, peridot is associated with the heart chakra and is believed to promote emotional healing and harmony in relationships. It is often called the "stone of compassion" and is said to calm anger, jealousy, and resentment, replacing them with a sense of peace and understanding. This aligns with the belief that peridot brings harmony to relationships, making it a popular gift for partners and friends.
Prosperity is another key symbolic meaning of the peridot. Its vibrant green color is often linked to growth and abundance. As a "symbol of prosperity," it is thought to attract wealth and success to the wearer. This belief makes it a favored stone for entrepreneurs and those seeking to advance their careers. The gem's association with the sun further enhances this symbolism, as the sun is a universal symbol of life, energy, and growth.
Peridot in Modern Jewelry
Today, peridot is a popular choice for a wide range of jewelry designs, from contemporary minimalist pieces to elaborate vintage-inspired creations. Its bright, cheerful color makes it a standout in any setting. One of the most popular forms of peridot jewelry is the birthstone stud earring. These earrings often feature a small, perfectly cut peridot set in a simple bezel or prong setting, allowing the stone's natural color to take center stage.
Modern designers often use peridot in combination with other materials to create unique and eye-catching pieces. For example, peridot can be set in gold vermeil, rhodium-plated sterling silver, or even paired with cubic zirconia for added sparkle. The Asscher cut, a square shape with step-cut facets, is a particularly popular choice for peridot, as it enhances the stone's depth and clarity.
When shopping for peridot jewelry, it is important to consider the quality of the stone and the craftsmanship of the setting. Look for gems with a vibrant, even color and good clarity. The setting should be secure and well-made to protect the gemstone. As peridot is a gemstone associated with August birthdays, it makes for a thoughtful and meaningful gift, carrying with it centuries of history and symbolism.
Care and Cleaning
Due to its moderate hardness, peridot requires careful handling and regular cleaning to maintain its brilliance. It is susceptible to scratching from harder materials like sapphire, ruby, and diamond. To avoid damage, it is best to store peridot jewelry separately from other pieces, ideally in a soft cloth pouch or a lined jewelry box.
Cleaning peridot is straightforward but should be done with care. Use warm, soapy water and a soft brush to gently clean the gemstone. Rinse it thoroughly to remove any soap residue. Avoid using harsh chemicals, ultrasonic cleaners, or steam cleaners, as these can damage the stone or the setting it is in.
It is also advisable to remove peridot jewelry before engaging in activities that could expose it to hard knocks or chemicals, such as sports, gardening, or cleaning. Following these simple care instructions will ensure that your peridot jewelry remains a beautiful and cherished piece for years to come.
Conclusion

From its ancient origins as a protective amulet in the hands of Egyptian pharaohs to its modern role as a cherished August birthstone, this gem has continuously captivated humanity with its unique olive-green hue and powerful symbolism. Its journey from the volcanic depths of the Earth to the surface has made it a symbol of renewal, strength, and harmony.
Whether appreciated for its geological rarity, its historical lore, or its vibrant aesthetic, the peridot holds a special place in the world of gemology.
