For individuals born on August 3, 1981, and indeed for all those celebrating birthdays in the eighth month of the year, the vibrant green of Peridot stands as the primary birthstone. While modern lists have expanded to include Spinel and Sardonyx, Peridot remains the most recognized gem associated with August. Its distinct color, which ranges from a bright lime green to a deeper olive, sets it apart from other green gemstones. Unlike many of its counterparts, the color of Peridot is not the result of impurities but is an intrinsic property of its chemical composition. This gem, often referred to historically as the "Gem of the sun," has a rich history that intertwines ancient civilizations, celestial events, and enduring symbolism. It is a stone of peace, good fortune, and happiness, traditionally believed to ward off evil and nightmares while bestowing loyalty and commitment upon the wearer. As a gem with a relatively moderate hardness, it requires specific care to maintain its luster, making knowledge of its properties essential for collectors and jewelry owners alike.
History and Lore
The history of Peridot is as deep and compelling as its green hues. The gem has been known and prized for thousands of years, with its origins of appreciation dating back to ancient Egypt. Historical accounts identify Egypt as a primary source for this gemstone, where it was frequently worn by the ancient Pharaohs. Its significance in this cradle of civilization was so profound that it was often mistaken for other precious green stones, most notably emeralds. This confusion is documented in several historical artifacts. For instance, the 200-carat stones that comprised the Three Holy Kings shrine in Germany’s Cologne Cathedral were, for centuries, believed to be emeralds. It was only later that gemologists identified them as peridots. This misidentification highlights the gem's impressive visual appeal and its capacity to rival the beauty of more traditionally valued green gems.
Beyond its use in royal adornment and religious artifacts, Peridot held a significant place in the folklore and spiritual beliefs of various cultures. The Romans were known to utilize the stone for protection against enchantment, believing it possessed the power to shield the wearer from magical influence. In the Middle Ages, the stone's lore evolved to include attributes of foresight and inspiration, suggesting that it could grant the wearer a glimpse into the future and stimulate creative thought. The ancient belief in its protective qualities has persisted in various forms. Some traditions hold that Peridot has the ability to ward off evil spirits and nightmares, providing a sense of peace and security to its owner. Furthermore, it is often associated with bestowing peace, loyalty, and commitment in one's love life, making it a meaningful gift for partners.
In a remarkable testament to its unique nature, Peridot has also been linked to celestial origins. In 2005, the Stardust space probe, on a mission to collect samples from a comet, returned with dust that was found to contain peridot crystals. This discovery confirmed that this earthly gem is also formed in the vastness of space, reinforcing its ancient title as the "Gem of the sun" and adding a cosmic dimension to its already storied history.
The August Birthstone Trio
While Peridot is strongly associated with August, it is important to acknowledge that it is one of three official birthstones for the month. This expansion of the birthstone list provides those born in August with a wider palette of choices in terms of color, symbolism, and affordability. The traditional birthstone for August is Sardonyx, a banded variety of chalcedony. Peridot was officially added to the modern list in 1912 by the American Gem Trade Association (AGTA) and Jewelers of America (JA), quickly becoming the most popular and widely recognized of the group. Spinel, the most recent addition, was included in 2016, further diversifying the options for August-born individuals.
The inclusion of multiple stones reflects a historical trend of adapting birthstone lists to meet market demands, ensuring a variety of options. Sardonyx, with its characteristic bands of reddish-brown sard and white onyx, offers an earthy, vintage aesthetic. It has long been viewed as a stone of protection, worn by ancient Greeks and Romans on talismans to harness courage and bravery on the battlefield. Spinel, available in a vast spectrum of colors including vivid red, pink, orange, blue, and black, is a versatile gem. It is often associated with renewal, inspiration, and vitality, serving as a high-energy stone for restoring energy and encouraging hope during difficult times. While these two stones offer unique histories and properties, Peridot remains the quintessential August birthstone, celebrated for its bright, uplifting energy and its distinct, uniform green color.
Geological Formation and Sources
Peridot is formed deep within the Earth's mantle and is brought to the surface through volcanic activity. Its chemical composition places it within the Forsterite-Fayalite mineral group, which is part of the olivine family. A key geological distinction of Peridot is that its color is an inherent part of its chemical makeup, rather than being caused by trace impurities as is the case with many other colored gemstones like ruby or sapphire. This intrinsic coloring results in a consistent green hue that only varies slightly in shade, occasionally exhibiting a subtle hint of yellow. The most prized colors are often described as a rich olive green or a vibrant lime green.
Historically, Egypt has been cited as the primary source for Peridot. The ancient mines on the island of Zabargad in the Red Sea were the source of many of the gems worn by Pharaohs and are believed to have been the origin of the stones that adorned the Cologne Cathedral shrine. While Egypt remains a significant location, Peridot is also found in other parts of the world. Sources of this gem include Myanmar (Burma), Pakistan, and the United States, particularly in Arizona and New Mexico. These locations produce peridots of varying sizes and qualities, contributing to the gem's availability in the global market.
Gemological Properties
Understanding the physical and chemical properties of Peridot is crucial for gemologists, jewelers, and consumers. These properties dictate the stone's durability, appearance, and care requirements.
- Chemical Composition: Peridot is magnesium iron silicate, with the chemical formula (Mg, Fe)₂SiO₄. The specific ratio of magnesium to iron determines the exact shade of green, with higher iron content leading to a deeper, more olive tone.
- Hardness: On the Mohs scale of hardness, Peridot rates between 6.5 and 7.0. This makes it a moderately durable gemstone, suitable for a variety of jewelry types. However, it is softer than many other popular gems, including sapphire and ruby (which rate 9 on the Mohs scale), and diamond (10). This relative softness means that it can be susceptible to scratching if worn daily, especially in rings or bracelets that are exposed to potential impact.
- Color: The color of Peridot is its most defining characteristic. It ranges from yellow-green to a deep olive green. The gem's color is consistent and is not known to exhibit pleochroism (showing different colors when viewed from different angles) to a significant degree.
- Clarity and Inclusions: Like many gemstones, Peridot can contain inclusions. However, high-quality peridots are often found with good clarity. The presence of certain inclusions can sometimes be used to distinguish natural peridot from synthetic or other similar-looking stones.
- Crystal System: Peridot crystallizes in the orthorhombic system.

Symbolism and Metaphysical Beliefs
Peridot has accumulated a wealth of symbolic meanings and metaphysical beliefs throughout its long history. Its bright, refreshing color naturally lends itself to concepts of vitality, growth, and renewal. Across different eras and cultures, it has been revered for its perceived ability to influence the wearer's life in positive ways.
One of the most prominent symbolic associations is with good fortune and happiness. The ancient Egyptians, who called it the "Gem of the sun," believed it brought the wearer joy, strength, and protection. This connection to the sun suggests a life-giving, energizing quality. The belief that it can ward off evil and nightmares contributes to its reputation as a protective stone, creating a sense of safety and peace for the individual.
In matters of the heart, Peridot is linked to loyalty and commitment. It is often considered a stone that can strengthen relationships and foster devotion, making it a popular choice for romantic gifts. This symbolism is so ingrained that Peridot is officially designated as the gemstone for the 16th wedding anniversary.
Metaphysically, Peridot is often associated with the Heart Chakra. Practitioners of crystal healing believe that it helps to open the heart to love, joy, and abundance. It is seen as a stone that can release negative patterns and old baggage, allowing for a fresh start and a more positive outlook on life. Its "uplifting energy" is thought to boost mood and confidence, aligning with its historical use as a stone of inspiration and foresight. While these metaphysical beliefs are not scientifically proven, they remain a significant part of Peridot's cultural legacy and contribute to its enduring appeal.
Care and Cleaning
Given its moderate hardness, Peridot requires careful handling and cleaning to preserve its beauty and integrity. While it is durable enough for most types of jewelry, its susceptibility to scratches means that precautions should be taken, especially for pieces that are worn frequently.
Daily Wear: When set in a ring or bracelet, Peridot can be exposed to knocks and abrasive surfaces. It is advisable to remove peridot jewelry before engaging in activities such as gardening, sports, or heavy household chores. For earrings or pendants, the risk of damage is significantly lower, making them excellent choices for showcasing this gem.
Cleaning: The best method for cleaning Peridot is straightforward and gentle. Use a soft-bristle brush (like a toothbrush) with a mixture of mild dish soap and warm water. Gently scrub the stone and its setting, then rinse thoroughly with warm water and pat dry with a soft, lint-free cloth. It is crucial to avoid harsh chemicals, ultrasonic cleaners, and steam cleaners, as these can damage the stone or its setting. Sudden and extreme temperature changes should also be avoided.
Storage: When storing Peridot, it should be kept separate from other jewelry to prevent scratching. It is best to store it in a soft-lined jewelry box or a separate pouch. Do not toss it into a drawer with other, harder gemstones like diamonds, sapphires, or rubies, as these can easily scratch the surface of the peridot.
Conclusion
Peridot stands as a gemstone of remarkable history, distinct scientific properties, and deep cultural significance. As the primary birthstone for August, it embodies the warmth and vitality of summer with its bright, lime-green color. Its legacy stretches from the ancient mines of Egypt to the dust of comets, earning it the moniker "Gem of the sun" and a place in the lore of protection, foresight, and love. While other stones like Spinel and Sardonyx also claim a place in the August birthstone list, Peridot's unique color—derived from its own chemical composition rather than impurities—and its rich tapestry of symbolism make it a standout choice. For those born on August 3, 1981, and for all August celebrants, Peridot offers not only a beautiful gem for adornment but also a connection to a timeless heritage of beauty and meaning. With proper care, this gem of the sun will continue to shine with its characteristic vibrancy for generations to come.
