Peridot, the radiant green gemstone associated with those born on August 7th, holds a unique place in the world of birthstones. Known for its vibrant hue, historical significance, and metaphysical properties, Peridot is more than just a decorative stone—it is a symbol of friendship, prosperity, and spiritual alignment. As the birthstone for August 7th, it carries a legacy that stretches back thousands of years and continues to captivate gemstone enthusiasts and jewelry collectors alike. While August is officially associated with three distinct birthstones—Peridot, Spinel, and Sardonyx—Peridot stands out for its singular color, extraterrestrial origins, and deep historical lore. This article explores the many facets of Peridot, from its geological formation and mineral composition to its role in history, culture, and modern jewelry, providing a comprehensive guide for those seeking to understand this "gem of the sun."
History and Lore
Peridot has a rich and storied history that spans cultures and continents. The gemstone has been mined and used for at least 5,000 years, with ancient Egyptians being among the earliest known admirers. They referred to Peridot as the “gem of the sun” and believed it possessed protective properties, shielding the wearer from the terrors of the night. This belief highlights the stone’s long-standing association with light and positivity. The ancient Egyptians sourced Peridot from the island of Topazios in the Red Sea, a location that would later cause significant confusion in gemological history. The island’s name, Topazios, led to the mistaken belief that the stones mined there were topaz, creating a legacy of misidentification that persisted for centuries.
This confusion extended beyond topaz to emeralds as well. Throughout history, Peridot has often been confused with other green gems, most notably emeralds. The Shrine of the Three Holy Kings in Germany’s Cologne Cathedral is decorated with 200 carats of gems that were historically believed to be emeralds but are, in fact, Peridot. Some historians even speculate that Cleopatra’s famous emerald collection may have been comprised of Peridot, suggesting that the allure of this green gem was central to the legendary queen’s taste. The word “peridot” itself is derived from the Arabic faridat, meaning "gem," a testament to its intrinsic value in Middle Eastern cultures. In medieval times, the gemstone was valued in many ancient and medieval cultures, often used in religious jewelry and talismans. It was believed to bring happiness and strength to the wearer and was thought to protect against nightmares.
One of the most intriguing aspects of Peridot’s history is its extraterrestrial origin. Peridot is one of the few gemstones found in meteorites and volcanic lava, which means it can be formed both on Earth and in space. This cosmic connection has added a layer of mystique to the stone, reinforcing its ancient title as the "gem of the sun." Its formation under extreme conditions, deep within the Earth’s mantle or in the voids of space, speaks to its resilience and rarity, making it a prized possession for collectors and spiritual seekers alike.
Geological Formation and Sources
Peridot, the yellowish green to greenish yellow gem variety of the mineral olivine, is unique in its formation process. Unlike many gemstones that crystallize in the Earth’s crust, Peridot is formed under extreme conditions deep within the Earth’s mantle. It is brought to the surface by volcanic activity, often found embedded in hardened lava that carried it from the planet’s interior. This volcanic origin explains why Peridot is sometimes found in igneous rocks and volcanic deposits.
Adding to its rarity, Peridot is also one of the few gemstones that have been discovered in meteorites. These extraterrestrial Peridots, formed in the depths of space, share the same chemical composition as their terrestrial counterparts but are forged in a completely different environment. This dual origin—terrestrial and extraterrestrial—makes Peridot a subject of great interest not only to gemologists but also to planetary scientists.
While Peridot deposits are found in various parts of the world, the most historically significant source remains the Red Sea island of Topazios (modern-day Zabargad). This location was the primary source of Peridot for the ancient world and continued to be mined until the 20th century. Other notable sources include Pakistan, which is known for producing large, high-quality Peridot crystals, and Arizona in the United States, where Peridot is found in volcanic rock. The gemstone’s formation in the Earth’s mantle means that it can be found in regions with significant volcanic activity, making locations like Hawaii and the Eifel region in Germany also part of its geological story. The combination of these sources ensures a steady supply of this vibrant gem, though high-quality, large-carat Peridots remain rare and valuable.
Gemological Properties
Peridot is celebrated for its distinct color, which ranges from bright yellow-green to deep olive green. This color is a direct result of its iron content, a key component of its chemical formula, (Mg, Fe)₂SiO₄. The presence of iron gives Peridot its signature hue, with the most prized specimens exhibiting a rich, vibrant green without strong brown or yellow undertones.
In terms of physical properties, Peridot is a relatively durable gemstone, making it suitable for various types of jewelry. It has a hardness of 6.5 to 7 on the Mohs scale, which means it is resistant to scratching but can still be damaged by harder materials like diamonds or sapphires. It has no cleavage, which is a significant advantage, as it reduces the risk of the stone splitting or cracking when struck. However, it is brittle and can be prone to chipping if not handled with care.
Peridot’s optical properties are also noteworthy. It is a doubly refractive gemstone, meaning that light entering the stone is split into two rays, creating a doubling effect that can be observed under magnification. Its refractive index ranges from 1.654 to 1.690, and it exhibits a characteristic "crisp" luster that enhances its vibrant color. The gemstone is typically found in small to medium sizes, though larger specimens have been discovered, particularly in Pakistan. The clarity of Peridot is generally high, with most stones being free of visible inclusions, though some may contain "lily pad" inclusions, which are disc-shaped bubbles that are considered a hallmark of natural Peridot.

Symbolism and Metaphysical Beliefs
Peridot’s symbolism is as vibrant as its color. Historically, it has been associated with light, positivity, and prosperity. The ancient Egyptians’ belief in its protective powers against evil spirits and nightmares underscores its role as a talisman for safety and well-being. Its association with the sun further reinforces these themes, suggesting that Peridot can bring warmth, joy, and clarity into the wearer’s life.
In modern metaphysical practices, Peridot is often linked to the Heart Chakra, the energy center associated with love, compassion, and emotional balance. It is believed to help release negative patterns, such as jealousy, resentment, and anger, and to open the heart to new relationships and experiences. This makes it a powerful stone for those seeking to heal emotional wounds or to cultivate a more positive outlook on life.
Prosperity and abundance are also key themes in Peridot’s symbolism. It is often called the "stone of prosperity" and is believed to attract wealth, success, and good fortune. This association makes it a popular choice for individuals looking to enhance their career prospects or to manifest their goals. Additionally, Peridot is said to boost confidence, mood, and vitality, making it an ideal gemstone for those who need a boost of energy and optimism. Its uplifting energy is described as "pure summer energy," a fitting description for a stone that embodies the warmth and vibrancy of August.
The August 7th Connection and Alternative Birthstones
While Peridot is the primary birthstone for August 7th, it is important to acknowledge the context of the other August birthstones, Spinel and Sardonyx. The modern list of birthstones, standardized by organizations like the American Gem Trade Association (AGTA) and Jewelers of America (JA), includes multiple stones for August to provide consumers with more options in terms of color, affordability, and availability.
Spinel, the second August birthstone, is a versatile gem available in a wide spectrum of colors, including vivid red, pink, orange, blue, and black. Historically, red spinel was often mistaken for ruby, and it was only recently recognized as a distinct and valuable gemstone. Spinel is associated with renewal, inspiration, and vitality. It is believed to be a high-energy stone that can help restore energy, inspire hope, and provide encouragement during difficult times. For those born on August 7th who prefer a gem with a royal history but a more modern appeal, Spinel is an excellent alternative.
Sardonyx, the original and traditional August birthstone, has a history dating back over 4,000 years. This gem is a variety of onyx, characterized by its earthy red, brown, and white banding. Sardonyx is deeply associated with grounding, protection, and stability. It is believed to support strength, courage, and stable relationships, making it a meaningful choice for those who value tradition and a connection to ancient history. Its vintage style and powerful, earthy energy offer a stark contrast to the bright, uplifting nature of Peridot.
For those born on August 7th, the choice between Peridot, Spinel, and Sardonyx allows for a personalized selection based on individual preference, style, and the specific energies one wishes to invoke. Peridot remains the quintessential August 7th birthstone, but the presence of these alternatives enriches the options available to those celebrating this birth date.
Care and Cleaning
Given its gemological properties, Peridot requires specific care to maintain its brilliance and integrity. With a hardness of 6.5 to 7 on the Mohs scale, it is durable enough for everyday wear but is softer than many other gemstones like diamonds, sapphires, and rubies. This means it should be protected from scratches and hard impacts. It is advisable to store Peridot jewelry separately in a soft cloth or lined jewelry box to prevent it from being scratched by harder stones.
Peridot is also sensitive to rapid temperature changes, which can cause internal fractures. Therefore, it should not be exposed to extreme heat or sudden temperature shocks, such as being placed in a hot ultrasonic cleaner or exposed to a flame for jewelry repair.
For cleaning, warm, soapy water and a soft brush are the safest and most effective methods. Gently scrub the stone and its setting to remove dirt and oils. Rinse thoroughly with clean water and dry with a soft, lint-free cloth. Avoid using harsh chemicals, bleach, or abrasive cleaners, as these can damage the stone’s surface. While an ultrasonic cleaner can be used if the stone is securely set and free of fractures, it is generally safer to avoid it. Steam cleaning is not recommended for Peridot due to its sensitivity to heat. With proper care and maintenance, Peridot jewelry can be passed down through generations, carrying with it the light and positive energy that this gemstone is known for.
