Peridot, with its distinctive olive-green hue, stands as the primary birthstone for those born on August 3rd. While the month of August boasts three official birthstones—Peridot, Spinel, and Sardonyx—Peridot holds a singular distinction for the specific date of August 3rd. This gemstone, a variety of the mineral olivine, is celebrated not only for its unique coloration but also for a history that spans ancient civilizations and geological marvels.
The significance of Peridot extends beyond its visual appeal. It is a gemstone formed under extreme conditions, found deep within the Earth’s mantle and even carried from outer space via meteorites. For the individual born on August 3rd, Peridot symbolizes friendship, love, and personal transformation. Its journey from the depths of the Earth to the hands of ancient royalty and modern collectors alike offers a compelling narrative of geological resilience and cultural reverence.
This article explores the multifaceted nature of Peridot, delving into its historical origins, geological formation, gemological properties, and the symbolism that has made it a cherished gem for millennia. We will examine why Peridot, often confused with emeralds in antiquity, commands its own unique place in the world of gemology and why it remains a vibrant choice for August-born individuals.
History and Lore
The history of Peridot is rich and varied, with records of its use dating back to ancient civilizations. One of the earliest and most significant sources of Peridot was the island of Zabargad (also known as Topazios) in the Red Sea. This island was the primary source of the gem for thousands of years, with mining operations dating back to as early as 1500 B.C. The ancient Egyptians highly prized this gemstone, referring to it as the "gem of the sun." They believed that Peridot protected its wearer from the terrors of the night and warding off evil spirits. It was often set in gold and worn as an amulet to ensure courage and strength.
The Egyptians were not the only civilization to revere this green stone. The Romans also held Peridot in high esteem, calling it the "evening emerald." They noted that the gemstone maintained its vibrant green color even under artificial light, making it a popular choice for jewelry worn after sunset. The Romans imported large quantities of Peridot from Egypt and used it extensively in decorative arts and adornments.
Throughout history, Peridot has frequently been mistaken for other gemstones, most notably emeralds. This confusion stems from its similar green hue. The Shrine of the Three Holy Kings in Germany’s Cologne Cathedral is decorated with 200 carats of gems that were long believed to be emeralds but are, in fact, Peridot. Some historians even speculate that Cleopatra’s famous collection of emeralds may have actually consisted of Peridot. This misidentification underscores the gemstone's beauty and value, which rivaled that of the most precious green gems.
The name "Peridot" itself is derived from the Arabic word faridat, meaning "gem." This etymology highlights the gem's long-standing status as a prized possession in Middle Eastern cultures. In medieval times, Peridot was used to ornament churches and cathedrals, further cementing its association with divinity and protection. The gemstone's lore is deeply intertwined with themes of light, protection, and clarity, reflecting its bright, translucent appearance.
Geological Formation and Sources
Peridot is unique among gemstones due to its formation process and the extreme conditions under which it occurs. It is the yellowish-green to greenish-yellow variety of the mineral olivine. Unlike many gemstones that form in the Earth's crust, Peridot is brought to the surface from deep within the Earth’s mantle. This process occurs through volcanic activity, where the gemstone is carried up in hardened lava.
The geological origins of Peridot are not limited to the Earth's interior. In a rare occurrence, Peridot has also been found in meteorites that have fallen to Earth. These extraterrestrial Peridots provide evidence of gem formation in outer space, making the stone even more extraordinary. The ability of Peridot to form in such diverse and harsh environments—both the molten depths of the Earth and the vacuum of space—speaks to its durability and unique chemical stability.
Historically, the volcanic island of Zabargad in the Red Sea was the main source of high-quality Peridot. However, today, the primary sources of Peridot are located in the United States, specifically in Arizona. The San Carlos Apache Reservation in Arizona is a major producer of Peridot, yielding gemstones of significant size and quality. Other notable sources include Pakistan, where the gem is mined in the Himalayas, and Myanmar (Burma).
The gemstone can also be found in Australia, Brazil, China, Kenya, Mexico, Norway, Sri Lanka, and Tanzania. However, the Peridot from Arizona is particularly well-known for its consistent supply and distinct color. The gemstone's presence in these varied global locations indicates a widespread geological distribution, though high-quality gem material remains relatively rare.
Gemological Properties
Peridot possesses a distinct set of gemological properties that distinguish it from other green gemstones. Understanding these characteristics is essential for gemologists and collectors alike.
Chemical Composition and Color: Peridot is a magnesium iron silicate with the chemical formula (Mg, Fe)2SiO4. Its signature green color is caused by the presence of iron. Unlike many other gemstones, Peridot is found only in one color family, ranging from yellowish-green to a deep olive hue. The intensity of the green depends on the amount of iron present in the crystal structure. The most valued Peridots are those with a pure, vibrant green without any brownish tints.
Hardness and Durability: On the Mohs scale of hardness, Peridot rates between 6.5 and 7. While this makes it durable enough for everyday wear, it is slightly softer than stones like sapphire or diamond. Consequently, Peridot requires some care to prevent scratching or abrasion. It does not possess cleavage, meaning it is less likely to split along internal planes when struck, which is a favorable characteristic for a gemstone used in jewelry.
Refractive Index and Clarity: Peridot has a refractive index ranging from 1.65 to 1.69. It is doubly refractive, meaning light splits into two rays as it passes through the stone, which can enhance its brilliance. Peridot usually has good clarity, though it may contain "lily pads"—round, fluid inclusions that resemble water droplets. These inclusions are characteristic of the stone and can help gemologists identify it. Unlike emeralds, which are known for their visible inclusions (jardin), Peridots are generally cleaner, offering a clearer view into the stone.
Carat Weight: Peridot is available in a wide range of sizes. While small stones are common, large Peridots are also found. Specimens weighing hundreds of carats are not uncommon, particularly from sources like Arizona and Pakistan. The availability of large, high-quality stones makes Peridot an attractive option for statement jewelry.
Here is a summary of key gemological properties:

Symbolism and Metaphysical Beliefs
Peridot has been attributed with various symbolic meanings and metaphysical powers throughout history. These beliefs span ancient traditions to modern crystal healing practices.
Protection and Power: In ancient Egypt, Peridot was believed to be a powerful talisman against evil. The Egyptians wore it to ward off nightmares and protect themselves from the terrors of the night. It was also associated with the sun god, Ra, bestowing upon the wearer vitality and strength. The Romans continued this tradition, viewing the "evening emerald" as a protector during the darkness.
Friendship and Love: One of the primary symbolic associations of Peridot, particularly for those born on August 3rd, is that of friendship and love. The gemstone is believed to open the heart to new relationships and strengthen existing bonds. It is often given as a token of affection and is thought to promote loyalty and devotion.
Personal Transformation and Renewal: The vibrant green color of Peridot is naturally associated with nature, growth, and renewal. It is considered a stone of transformation, helping individuals shed old patterns and embrace positive change. Metaphysical practitioners believe that Peridot stimulates the heart chakra, allowing for emotional healing and the release of past burdens. It is said to bring joy and a sense of new beginning to the wearer.
Healing Properties: In modern crystal healing, Peridot is believed to have physical healing properties as well. It is associated with the physical heart, lungs, and spleen. Practitioners believe it can help cleanse the body of toxins and support the immune system. While these claims are not scientifically verified, they contribute to the stone's enduring popularity in holistic communities.
Care and Cleaning
Due to its specific physical properties, Peridot requires proper care to maintain its brilliance and integrity. While it is durable enough for most jewelry types, it is softer than many other gemstones and is susceptible to thermal shock.
Cleaning Instructions: Peridot can be cleaned using warm, soapy water and a soft brush. It is important to avoid harsh chemicals, such as bleach or ammonia, as these can damage the stone's surface. Ultrasonic cleaners are generally safe for Peridot, but steam cleaning should be avoided. Sudden changes in temperature, such as moving from hot water to cold, can cause the stone to fracture due to its internal inclusions.
Storage and Handling: When not being worn, Peridot jewelry should be stored separately from other gemstones to prevent scratching. A soft cloth pouch or a lined jewelry box is ideal. Because Peridot rates between 6.5 and 7 on the Mohs scale, it can be scratched by harder stones like diamonds, sapphires, and rubies.
Durability Concerns: Peridot has poor toughness, meaning it is somewhat brittle and can chip or crack if struck against a hard surface. It is not recommended for rings that will be subjected to heavy daily wear, such as those worn by people working with their hands. However, with careful handling, Peridot jewelry can remain beautiful for generations.
