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.
In this article, we explore the many facets of Peridot, from its geological formation and mineral composition to its role in history, culture, and modern jewelry. We also examine its symbolic meaning and how to care for this gemstone to preserve its beauty for generations.
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.
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 adds to its mystique and reinforces its symbolic link to light and energy.
In more recent history, Peridot has also been confused with other gemstones. For example, the Red Sea island of Topazios—often considered the source of the name “topaz”—actually produced Peridot, not topaz. Similarly, the Shrine of the Three Holy Kings in Germany’s Cologne Cathedral was believed to be adorned with emeralds, but these were later identified as Peridot. This historical misidentification underscores the gem’s visual similarity to other stones and its enduring allure.
Peridot has also been speculated as a possible component of Cleopatra’s famous emerald collection. While this remains a theory, it speaks to the high regard in which the gem was held by ancient royalty and leaders.
Geological Formation and Sources
Peridot is a gem-quality variety of the mineral olivine. Its distinct green color is due to the presence of iron in its chemical structure. The gem is formed under extreme conditions, typically in the Earth’s mantle, and is carried to the surface through volcanic activity. This means that Peridot is often found in hardened lava flows and in meteorites that have landed on Earth.
The formation of Peridot is tied to high-pressure and high-temperature environments, which contribute to its durability and unique characteristics. Unlike some gemstones that can form in a variety of colors depending on trace elements, Peridot is one of the few that occurs only in shades of green. This is because its color is directly tied to its chemical composition, with iron being the key element responsible for its hue.
Peridot is mined in several parts of the world, with notable sources including:
- United States: Particularly in Hawaii and Arizona, where it is found in volcanic lava flows.
- Egypt: Known for its ancient deposits, with the island of Zabargad in the Red Sea being a famous source.
- Brazil: Produces some of the finest Peridot in vibrant green shades.
- Afghanistan: A traditional source of high-quality Peridot.
- Pakistan and Myanmar: Also known for producing Peridot, often in smaller sizes.
These global sources contribute to the gemstone’s availability and affordability, making it a popular choice for jewelry and personal adornment.
Gemological Properties
Peridot is a versatile gemstone with a range of physical and optical properties that make it both attractive and durable. Here are some key characteristics of Peridot:
- Chemical Composition: (Mg,Fe)₂SiO₄ (Olivine group)
- Color: Varies from yellow-green to deep green, depending on the concentration of iron.
- Hardness (Mohs Scale): 6.5 to 7.0
- Refractive Index: 1.65 to 1.70
- Specific Gravity: 3.2 to 4.3

- Inclusions: Common, including small mineral grains and fractures
Peridot’s hardness makes it suitable for use in various types of jewelry, including rings, necklaces, and earrings. However, it is not as hard as diamonds or sapphires, so it requires careful handling to avoid scratches or damage. Its refractive index and color also contribute to its brilliance and visual appeal, making it a favorite among jewelers and collectors.
One of the most distinctive features of Peridot is its consistent color. Unlike many other gemstones that can exhibit a range of colors depending on trace elements or lighting conditions, Peridot maintains its green hue across different environments. This makes it a reliable and easily recognizable gemstone.

- Avoid Ultrasonic Cleaners: While some gemstones can be safely cleaned with ultrasonic cleaners, Peridot is not recommended for this method due to its potential for cleavage and inclusions.
- Store Separately: To prevent scratches, store Peridot jewelry separately from harder gemstones like diamonds or sapphires. A soft pouch or individual compartment in a jewelry box is ideal.
- Avoid Extreme Temperatures: Sudden temperature changes can cause stress on the gemstone, so it is best to avoid exposing Peridot to extreme heat or cold.
