This article will delve into the multifaceted world of the August birthstone, providing essential knowledge for gemstone lovers, prospective buyers, and students of gemology.
History and Lore: The Gem of the Sun
Peridot has been treasured for millennia, with its history stretching back to ancient civilizations. Its most notable historical significance is tied to the island of Zabargad in the Red Sea, which was the primary source of peridot for centuries. The ancient Egyptians mined this gem, known to them as the 'gem of the sun,' believing it possessed protective qualities against the forces of darkness and nightmares. It was often set in gold and worn as an amulet to ward off evil. The stones were also used to ornament religious objects and were believed to be a favorite of Cleopatra, though many of the "emeralds" she wore were likely peridots.
Throughout history, peridot has been mistaken for other green gemstones, including emerald. Many of the large, fine green gems in the world's ecclesiastical and royal collections, such as those in the Treasury of the Vatican, were originally identified as emeralds but have since been reclassified as peridot. This confusion highlights the gem's remarkable beauty and its ability to rival more famous stones. The stone's lore extends to its supposed healing properties; medieval Europeans believed it could cure asthma and other ailments, while the ancient Burmese mined it on an island in the Red Sea, believing it had the power to light up the night and dispel fear.
The journey of peridot to its modern status as a birthstone is a more recent development. The American National Association of Jewelers (now Jewelers of America) established a standardized list of birthstones in 1912, which included peridot for August. This list has been updated over the years, but peridot has remained a constant, a testament to its enduring popularity and cultural resonance. Its designation as a birthstone solidified its place in modern jewelry, making it a popular choice for rings, pendants, and earrings that serve as personal talismans and celebratory gifts.
Geological Formation and Sources
Peridot is unique among gemstones as it is found not only in the Earth's crust but also in the mantle, the layer of the planet between the core and the crust. It is one of the few gemstones that are formed in this deep, high-pressure environment and brought to the surface by volcanic activity. The primary mineral composition of peridot is forsterite, a magnesium iron silicate, with the gem’s signature green color derived from the presence of iron. The intensity and shade of the green depend on the amount of iron in the crystal structure.
The formation process begins deep within the Earth's upper mantle. Here, under immense heat and pressure, crystals of peridot grow. Tectonic or volcanic activity then forces these crystals upward, where they can be found in two main types of rock: peridotite and basalt. In some cases, peridot crystals are carried to the surface in lava flows. A remarkable source of peridot are pallasite meteorites, which are stony-iron meteorites that contain yellowish-green olivine crystals. These extraterrestrial peridots provide a fascinating glimpse into the gem's formation beyond our planet.
Historically, the most significant source of gem-quality peridot was the island of Zabargad (also known as St. John's Island) in the Red Sea. This location has been exploited since ancient times and produced some of the finest peridots ever found. While production from this source has diminished, other locations have become important suppliers. Today, peridot is mined in various parts of the world, including Pakistan, which is known for producing large, high-quality crystals from the remote region of the Pakistan-Afghanistan border. Other significant sources include Myanmar (Burma), Vietnam, and the United States, particularly in Arizona, where peridot is found in basaltic lava fields. The material from Arizona often produces smaller, but still vibrant, gems suitable for jewelry.
Gemological Properties
Understanding the gemological properties of peridot is essential for appreciating its value and durability. As a gemstone, it possesses a set of characteristics that define its appearance, resilience, and care requirements. Its most celebrated attribute is its color, but its hardness and clarity are also critical factors in its suitability for jewelry, especially for items like rings that are subject to daily wear.
Peridot is a member of the olivine family and has a hardness of 6.5 to 7 on the Mohs scale. This makes it a relatively durable gemstone, though it is softer than topaz (8) or corundum (9, including ruby and sapphire). Its toughness is generally considered good, but it does have a tendency to chip or cleave if struck with sufficient force, so protective settings like bezels are often recommended for rings. Peridot is also sensitive to rapid temperature changes, which can cause fracturing.
The color of peridot is its most defining feature. It is one of the few gemstones that occurs in only one color: a distinct olive-green. The shade can vary from yellowish-green to a more brownish-olive, with the most prized color being a rich, vibrant lime green or olive green with no brownish tints. This color is caused by the presence of iron and is not typically treated to enhance its hue, which makes a fine peridot a naturally beautiful gem. In terms of clarity, peridots are often found with inclusions. A common feature is "lily pad" inclusions, which are disc-like fractures that can give the stone a lustrous, silky appearance. While eye-clean peridots are available and highly valued, some inclusions are accepted as part of the stone's natural character.

Cutting and setting peridot requires skill to maximize its color and brilliance. The gem is often faceted to enhance its sparkle, with popular cuts including oval, pear, round, and cushion shapes. Its strong pleochroism (showing different shades of green when viewed from different angles) is an important consideration for cutters, who orient the stone to display the most desirable color face-up. For jewelry, peridot is set in a variety of metals. Yellow gold and peridot create a classic, warm combination, while white gold and platinum provide a cool, modern contrast that makes the green hue pop. Rose gold can also complement peridot, offering a soft, romantic aesthetic.
Symbolism and Metaphysical Beliefs
The symbolism associated with peridot is as rich and vibrant as its color. Throughout history, it has been imbued with a variety of meanings, from a source of light and protection to a symbol of peace and good fortune. These beliefs have contributed to its enduring appeal and its status as a cherished talisman.
The ancient Egyptians' belief that peridot was the 'gem of the sun' is central to its symbolism. They thought it could ward off evil spirits and protect its wearer, especially during the night. This protective quality was believed to be so strong that it could dispel fear and bring a sense of security. The stone's connection to the sun also imbued it with qualities of warmth, vitality, and abundance. In medieval Europe, peridot was considered a stone of healing, believed to be effective in treating asthma and other respiratory ailments, as well as promoting sleep and calming anger.
In modern crystal healing and metaphysical circles, peridot is associated with the heart chakra and is considered a stone of compassion and emotional balance. It is believed to help heal emotional wounds, mend relationships, and foster a sense of peace and forgiveness. Its vibrant energy is said to attract abundance, prosperity, and success, making it a popular choice for those seeking to improve their financial situation or achieve their goals. For those born in August, peridot is thought to enhance their natural Leo or Virgo traits, promoting confidence, clarity, and a positive outlook on life.
Beyond personal well-being, peridot is also a traditional gift for the 16th wedding anniversary, symbolizing long-lasting love and commitment. Its bright, cheerful energy is seen as a reflection of a happy and enduring partnership. Whether worn for its historical protective powers, its healing properties, or simply as a beautiful piece of jewelry, peridot carries a message of hope, strength, and positivity.
The August Birthstone Ring: A Modern Accessory
The peridot ring is a quintessential piece of jewelry for anyone born in August, offering a stylish way to wear this meaningful gemstone. Modern jewelry design has embraced peridot for its vibrant color and versatility, creating rings that range from simple, everyday pieces to elaborate statement designs. These rings are not only beautiful but also practical, making them a popular choice for both personal adornment and as thoughtful gifts.
Contemporary peridot rings are crafted from a variety of materials to suit different styles and budgets. For a durable and affordable option, some designs utilize stainless steel or sterling silver settings paired with peridot-hued stones. These pieces offer a modern aesthetic and are ideal for daily wear. For a more traditional and luxurious feel, peridot is frequently set in gold. Yellow gold provides a classic, warm backdrop that complements the gem's green tones, while white gold or platinum offers a sleek, contemporary look. Rose gold settings provide a trendy, romantic option that contrasts beautifully with the peridot's color.
The design of the August birthstone ring is often simple and elegant, focusing on the beauty of the central gemstone. Dainty stacking rings with a small, light green cubic zirconia (a popular peridot alternative) are a popular trend, allowing for a subtle touch of color. These rings can be worn alone for a minimalist look or stacked with other bands for a personalized style. For those seeking a more substantial piece, rings featuring a larger, natural peridot stone are available in settings like solitaire, halo, or three-stone designs. The choice of cut, from classic oval to modern pear-shaped, further personalizes the ring.
When selecting a peridot ring, it is important to consider the recipient's lifestyle. For individuals with active lives or jobs that involve frequent use of their hands, a bezel setting is a practical choice as it offers superior protection for the stone. A prong setting, on the other hand, allows more light to enter the gem, enhancing its brilliance, but may be more vulnerable to impact. Regardless of the style, a peridot ring is a meaningful and vibrant accessory that celebrates the warmth and positivity associated with the August birthstone.
Care and Cleaning
Proper care is essential to maintain the beauty and longevity of a peridot ring. While peridot is reasonably durable, it is softer than some other popular gemstones and can be susceptible to damage if not handled with care. Following a few simple guidelines will ensure that your August birthstone ring remains a sparkling and cherished piece for years to come.
Cleaning a peridot ring is a straightforward process. The safest and most effective method is to use warm water, a drop of mild dish soap, and a soft brush, such as a toothbrush with soft bristles. Gently scrub the stone and the setting to remove any dirt or oils, then rinse thoroughly under warm running water. It is important to pat the ring dry with a soft, lint-free cloth to prevent water spots and restore its shine. Avoid using ultrasonic cleaners, as the vibrations can cause existing fractures within the stone to worsen, potentially leading to damage. Steam cleaners are also not recommended for peridot.
Chemical exposure is a significant risk to peridot. The gemstone is sensitive to harsh chemicals, which can dull its surface or cause permanent damage. It is crucial to remove a peridot ring before using household cleaners, swimming in chlorinated pools, or applying lotions, perfumes, and hairspray. The chlorine in pool water can be particularly damaging, so it is best to store the ring safely before taking a dip. Even the natural oils and acids from the skin can build up over time, which is why regular, gentle cleaning is so important.
Storage is another key aspect of peridot care. When not being worn, a peridot ring should be stored separately from other jewelry to prevent scratches. While peridot has a hardness of 6.5 to 7, it can be scratched by harder gemstones like diamonds, sapphires, and rubies. Storing the ring in a soft pouch or a separate compartment in a lined jewelry box is the best way to protect it from damage. By adhering to these care instructions, you can preserve the vibrant sparkle and integrity of your peridot birthstone ring, ensuring it remains a radiant symbol of warmth and personal significance.
Conclusion
Peridot stands as a remarkable and historically rich gemstone, perfectly embodying the vibrant spirit of its status as August's primary birthstone. Its unique, sunlit green hue, a result of its iron-rich composition, sets it apart in the world of colored gemstones. From its ancient origins as the 'gem of the sun' in Egyptian lore to its modern interpretation as a symbol of peace and prosperity, peridot has consistently been valued for its beauty and perceived powers. Its geological formation deep within the Earth and its occasional extraterrestrial presence in meteorites only add to its mystique and appeal.
For gemstone enthusiasts and jewelry buyers, the peridot ring offers a combination of aesthetic beauty, practical durability, and profound symbolism. Its hardness of 6.5 to 7 on the Mohs scale makes it suitable for a variety of jewelry settings, including the ever-popular birthstone ring, though proper care is required to protect it from harsh chemicals and physical impact. The gem's single-color range, from yellowish-green to olive, provides a consistent and cheerful palette that complements a wide array of metals and design styles. Whether set in a simple stacking band or a more elaborate design, a peridot ring is a timeless piece that captures the essence of late summer.
Ultimately, the enduring significance of the August birthstone lies in its ability to connect the wearer to a rich tapestry of history, geology, and personal meaning. It is more than just a beautiful green stone; it is a piece of the Earth's fiery heart, a historical artifact, and a personal emblem of strength and good fortune. Its continued popularity in modern jewelry, from affordable and chic designs to high-end custom pieces, confirms its lasting appeal. As a beacon of light and positivity, the peridot birthstone ring remains a perfect and meaningful way to celebrate an August birthday.
