For those born on August 27th, the designated birthstone is peridot, a gemstone distinguished by its captivating olive-green hue. Unlike many gemstones that display a spectrum of colors, peridot is unique in occurring in a single color family, ranging from yellow-green to olive green. This gem is not only a visual delight but also a geological marvel, formed under extreme conditions deep within the Earth’s mantle and occasionally found in meteorites that journeyed from outer space. Its history is rich with mistaken identity, often being confused with emeralds and topaz, yet it has carved out a distinct legacy as a symbol of the sun, renewal, and personal growth. This article explores the multifaceted nature of peridot, from its volcanic genesis and historical lore to its gemological properties and practical care.
History and Lore
The narrative of peridot is deeply interwoven with ancient history and frequent misidentification. Throughout the centuries, this vibrant green gem has often been confused with other green stones, most notably emerald and topaz. The Red Sea island of Topazios, now known as Zabargad, was historically a primary source of peridot. Despite its name suggesting a source of topaz, the island actually yielded significant quantities of peridot, leading to the gem being referred to as "topaz" for a considerable period. This confusion extended to some of history's most famous gem collections. Some historians speculate that Cleopatra’s famed emerald collection may have actually consisted largely of peridot sourced from Zabargad. Further testament to this confusion is found in Germany’s Cologne Cathedral, where the Shrine of the Three Holy Kings is decorated with 200 carats of gems long believed to be emeralds, which are in fact peridot.
Ancient Egyptians held peridot in particularly high regard, calling it "the gem of the sun." They prized its vibrant, sunlit color and believed it possessed the power to ward off nightmares and provide protection from evil spirits. The island of Zabargad, though rich in the gem, was notoriously difficult to mine, earning ominous names like the Island of Death and Ophiodes (Snake Island) due to its harsh conditions.
The journey of peridot to becoming a modern birthstone is a reflection of evolving traditions. While sardonyx is the original August birthstone with a history dating back more than 4,000 years, the 20th century saw jewelers and gem associations update these lists to include more affordable or accessible alternatives. Peridot, with its distinct beauty and growing availability, emerged as a primary choice. Today, peridot is also considered the birthstone for the zodiac sign Leo, representing motivation and creativity. For those born under the sign of Virgo, which includes those with an August 27th birthday, carnelian is the primary gemstone, with peridot listed as an alternative, symbolizing hard work and empathy.
Geological Formation and Sources
Peridot’s formation occurs under conditions of intense heat and pressure, setting it apart from many other gemstones. It is the yellowish green to greenish yellow gem variety of the mineral olivine. The geological origins of peridot are particularly fascinating because it is found in two distinct environments: deep within the Earth’s mantle and in extraterrestrial meteorites.
From a terrestrial perspective, peridot is commonly found in volcanic rocks. It is brought to the Earth's surface from deep within the mantle by volcanic activity, often carried within hardened lava. This volcanic origin contributes to its symbolism of renewal and rebirth, as it is literally a gemstone born from the fire and brimstone of the Earth's interior. The association with renewal makes it a powerful stone for those seeking personal growth and transformation.
In addition to its earthly volcanic origins, peridot is one of the few gemstones known to exist in meteorites that have fallen to Earth from outer space. This extraterrestrial occurrence adds a layer of mystique and scientific interest to the gem, reinforcing its status as a stone formed under extreme and unique conditions.
The primary historical source of peridot is the Red Sea island of Zabargad (formerly Topazios). This island was the source of many of the ancient peridots that were later mistaken for emeralds. While Zabargad remains historically significant, modern sources of peridot are found in various locations around the world, continuing the legacy of this captivating green gem.
Gemological Properties
Understanding the physical and chemical characteristics of peridot is essential for gemologists, jewelers, and enthusiasts. Its properties dictate not only its appearance but also its durability and care requirements.
Peridot is a relatively durable gemstone, with a Mohs hardness of 8.5. This makes it suitable for various types of jewelry, as it is resistant to scratching and abrasion in everyday wear. However, despite its hardness, it still requires careful handling. Its chemical composition is that of the mineral olivine, which is abundant in the Earth’s mantle.
The most defining characteristic of peridot is its color. It is one of the few gemstones that occur in a single color, ranging from a yellow-green to an olive green. This unique color profile sets peridot apart from other gems, making it a popular choice for those looking to express individuality through their birthstone. The vibrant green color is also associated with the heart chakra in Eastern philosophies, where it is believed to help heal emotional wounds and foster feelings of love and compassion.
The following table summarizes the key gemological properties of peridot as derived from the available information:
| Property | Description |
|---|---|
| Mineral | Olivine |

Symbolism and Metaphysical Beliefs
Peridot’s symbolism is as rich and varied as its history, blending ancient beliefs with modern interpretations. Historically, its connection to the sun in Egyptian culture imbued it with protective and warding properties. In contemporary contexts, peridot is often associated with qualities such as prosperity, growth, and vitality. It is thought to bring good fortune and to promote emotional balance and mental clarity. Those who wear peridot are believed to experience a sense of renewal and rejuvenation, making it an ideal stone for personal transformation and self-improvement.
The gem’s association with the heart chakra in Eastern philosophies underscores its role in emotional healing. The vibrant green color is believed to resonate with the heart, helping to heal emotional wounds and foster feelings of love and compassion. This makes peridot a powerful tool for those seeking to enhance their emotional well-being and strengthen their relationships.
For individuals born on August 27th, peridot serves as a symbol of their unique qualities. As an alternative birthstone for Virgo, it represents hard work and empathy, aligning with the diligent and caring nature often associated with this earth sign. For Leos, it embodies motivation and creativity, fueling their passionate and dynamic spirit.
Care and Cleaning
Given its gemological properties, peridot requires specific care to maintain its brilliance and integrity. With a Mohs hardness of 8.5, it is relatively durable, but it is not impervious to damage. The sources recommend appropriate care to maintain its brilliance. While specific cleaning methods are not detailed, it can be inferred that gentle cleaning with warm, soapy water and a soft cloth is suitable.
It is crucial to avoid harsh chemicals, ultrasonic cleaners, and steam cleaners, as these could potentially damage the gem. Due to its volcanic origins and internal characteristics, peridot should be handled with care to avoid hard knocks or rapid temperature changes, which could cause fractures. Proper care ensures that this vibrant green gemstone will retain its stunning color and sparkle for generations.
