For those born on August 9th, the birthstone of choice is Peridot, a gemstone celebrated for its radiant green hue and rich historical significance. Peridot has captivated cultures across millennia, from the ancient Egyptians who revered it as the “gem of the sun” to modern gemologists who study its unique properties. This article explores the geological formation, historical uses, symbolic meanings, and practical care of Peridot, highlighting its enduring appeal as a birthstone and gemstone of choice.
A Historical Gemstone: From Ancient Egypt to Modern Symbolism
Peridot's history is as vivid as its color. Known in ancient times as chrysolite, Peridot was particularly valued in Egypt, where it was believed to possess protective qualities. The ancient Egyptians associated the gem with the sun and believed it could ward off nightmares and negative energies. This belief was so strong that it earned the moniker “the gem of the sun.” Some historical accounts even suggest that Peridot was mistaken for emeralds in ancient Egypt due to its deep green color.
Beyond Egypt, Peridot has been found in archaeological sites across the Roman Empire, where it was carved into amulets and used in jewelry. Sardonyx, another August birthstone, was especially favored in Roman times for its suitability in carving detailed cameos and reliefs. The use of Peridot and Sardonyx in such artifacts highlights the gemstone’s significance in both decorative and symbolic contexts.
By the 20th century, Peridot had become the most widely recognized birthstone for August, particularly in the United States and the United Kingdom. It is important to note, however, that August originally had multiple birthstones, including Sardonyx, Carnelian, and even Moonstone and Topaz. The consolidation of these into a single primary birthstone—Peridot—reflects both the gem’s visual appeal and its historical continuity.
In the realm of astrology and zodiac symbolism, Peridot has also found a place. It is associated with the zodiac sign Leo in some systems, reinforcing its connection to vitality, creativity, and protection. In Chinese and Leo traditions, Peridot is linked to prosperity, happiness, and the promotion of creative energy.
Geological Formation and Sources of Peridot
Peridot is a member of the olivine mineral group, a family of minerals composed primarily of magnesium, iron, and silica. Its chemical composition is typically represented by the formula (Mg,Fe)₂SiO₄, where the ratio of magnesium to iron determines the gem's color. The more iron present in the crystal structure, the deeper the green hue.
Peridot is formed deep within the Earth's mantle and is brought to the surface through volcanic activity. It is often found in basaltic lava flows and in meteorites, where it occurs naturally as a component of extraterrestrial rock. This unique origin has led some to refer to Peridot as a “cosmic gem,” given its presence in space rocks and its terrestrial volcanic formation.
The most notable sources of Peridot include:
- Zabargad Island (St. John’s Island), Egypt: Known as the historical source of high-quality Peridot, this island has been mined for centuries and was a major supplier in the ancient world.
- Arizona, USA: Arizona is one of the leading sources of Peridot in the modern era. The gem is found in volcanic rocks and is often mined in open-pit quarries.
- Madagascar and Burma (Myanmar): These locations also produce high-quality Peridot, contributing to the global supply of the gem.
Peridot is typically found in transparent to translucent form, with a glassy luster that enhances its visual appeal. It has a hardness of 6.5 to 7 on the Mohs scale, making it relatively durable for jewelry use, though it is still softer than many other gemstones like ruby or sapphire.
Gemological Properties of Peridot
Peridot is a gemstone of remarkable clarity and color. Its unique hue, ranging from yellow-green to olive-green, is one of the defining features of the gem. The intensity of the green color is directly related to the amount of iron in the crystal structure. This color variation allows for a range of aesthetic options in jewelry design, from bright and vibrant to deep and subdued.
Key gemological properties of Peridot include:
| Property | Description |
|---|---|
| Chemical Formula | (Mg,Fe)₂SiO₄ |
| Crystal System | Orthorhombic |
| Hardness (Mohs) | 6.5 – 7 |
| Refractive Index | 1.65 – 1.70 |
| Specific Gravity | 3.25 – 4.35 |
| Color | Yellow-green to olive-green |
| Luster | Vitreous (glassy) |
| Transparency | Transparent to translucent |
| Cleavage | Perfect in two directions |
| Fracture | Conchoidal |
| Fluorescence | Inert (no fluorescence) |
Peridot is typically faceted to enhance its brilliance and color. Because of its perfect cleavage, it is important to handle Peridot carefully during cutting and setting. Jewelers often choose secure settings, such as bezel or tension settings, to minimize the risk of damage.
The gem's refractive index contributes to its lively sparkle, though it does not have the same level of dispersion (fire) as diamonds or other refractive gemstones. Nevertheless, Peridot's color and clarity make it a highly sought-after gemstone for both everyday and special occasion jewelry.
Symbolism and Metaphysical Beliefs
Throughout history, Peridot has been associated with various metaphysical and symbolic meanings. In ancient times, it was believed to protect the wearer from nightmares and negative energies. The gem was also thought to promote healing and emotional balance, making it a popular choice for those seeking protection and inner peace.

It is believed to help release emotional blockages, encourage optimism, and foster a positive outlook on life. Peridot is also associated with the heart chakra and is thought to support emotional healing and compassion.
Peridot is often used in meditation and energy-balancing rituals, where it is believed to enhance spiritual growth and self-awareness. Some practitioners recommend wearing Peridot to reduce stress and anxiety, and to promote a sense of calm and clarity.
In certain cultural traditions, Peridot is also associated with prosperity and creativity. It is believed to attract abundance and success, making it a valuable gemstone for those seeking personal and professional growth.
Peridot in Jewelry and Contemporary Use
Peridot's popularity in jewelry is due to its beautiful color, relative affordability, and availability. It is often used in rings, earrings, pendants, and bracelets. Its vibrant green hue makes it a versatile gemstone that can be paired with a variety of metals, including gold, silver, and platinum.
Peridot is particularly popular in vintage and antique jewelry designs, where it is often used in art nouveau and art deco styles. Its warm, inviting color complements both warm and cool metal tones, making it a flexible choice for designers.

Peridot is also gaining recognition in the wellness and self-care industries, where it is used in meditation stones, chakra jewelry, and energy-balancing tools. Its association with positive energy and emotional healing makes it a valuable addition to a holistic lifestyle.
Care and Maintenance of Peridot
Because of its moderate hardness and perfect cleavage, Peridot requires careful handling and cleaning to maintain its beauty and durability. Here are some tips for caring for Peridot jewelry:
- Avoid Hard Impacts: Peridot can be damaged if struck by harder gemstones or objects. It is best to store Peridot jewelry separately from other gems like diamonds or sapphires to prevent scratches.
- Use Gentle Cleaning Methods: Peridot can be cleaned using mild soap and warm water. A soft cloth or a jewelry brush can be used to gently clean the gem. Avoid using harsh chemicals or ultrasonic cleaners, as these can damage the gem or its setting.
- Avoid Extreme Temperatures: Peridot should not be exposed to extreme heat or cold, as this can cause internal stress and potential fractures in the gem.
- Secure Settings: Due to its perfect cleavage, Peridot should be set in secure settings such as bezel or tension settings to prevent the gem from becoming loose or damaged.
- Professional Cleaning and Inspection: It is a good idea to have Peridot jewelry professionally cleaned and inspected once a year to ensure that the gem remains secure and in good condition.
By following these care guidelines, Peridot jewelry can remain beautiful and durable for many years.
