History and Lore
Peridot has a rich and storied history, with evidence of its use dating back thousands of years. Ancient Egyptians were among the first to recognize and value this gemstone. They referred to peridot as the "gem of the sun," believing it to possess protective qualities and the power to ward off evil spirits. Pharaohs and other high-ranking individuals often wore peridot jewelry, particularly during the night, to safeguard themselves from nightmares and the "evil eye."
The gemstone's connection to the sun is one of its most enduring themes. This association is reflected in its vibrant green hue, which evokes the warmth and light of sunlight filtering through lush foliage. The Egyptians also believed that peridot had the power to bring renewal and rebirth, making it a symbol of hope and rejuvenation.
In medieval Europe, peridot continued to be valued for its protective properties. It was often used as a talisman, believed to bring good fortune and guard the wearer from harm. Some historical accounts suggest that peridot was considered a sacred stone by various cultures, including those in the Middle East and Asia, where it was incorporated into religious and ceremonial practices.
One of the most fascinating aspects of peridot’s history is its cosmic origin. While most gemstones form within the Earth's crust, peridot can also be found in meteorites. This extraterrestrial connection adds to the gemstone's mystique, as it is one of the few gemstones that can be found both on Earth and in outer space.
The modern recognition of peridot as the birthstone for August was officially established in 1912 by the American Gem Trade Association (AGTA) and the Jewelers of America (JA). Over time, additional birthstones were added to the list to provide more options for consumers. In 2016, spinel was added to the list of August birthstones, alongside peridot and sardonyx. This expansion reflects the gemstone industry’s desire to offer a wider variety of colors, styles, and affordability.
Geological Formation and Sources
Peridot is a mineral of the olivine family, and its formation is closely tied to the Earth's geological processes. It forms deep within the Earth’s mantle, where high temperatures and pressures cause the crystallization of silicate minerals. Volcanic activity is responsible for bringing peridot to the Earth's surface, where it can be mined.
The chemical composition of peridot is primarily magnesium iron silicate, with the formula (Mg,Fe)₂SiO₄. The presence of iron in its structure is responsible for its green coloration. The more iron a peridot contains, the deeper its green hue. This variation in color is one of the gemstone's most distinctive features, allowing for a wide range of aesthetic applications.
Peridot is found in various parts of the world, with significant deposits in the United States, China, Brazil, Egypt, and Pakistan. The island of Zabargad in the Red Sea, known as Topazios in ancient times, is one of the most famous sources of peridot. This island was historically known for its peridot deposits, which were used by the ancient Egyptians and other civilizations.
In addition to terrestrial sources, peridot can also be found in meteorites. These meteorites are believed to have formed billions of years ago in space and have since landed on Earth. The discovery of peridot in meteorites has sparked scientific interest, as it provides insights into the formation of the solar system and the conditions that existed in space.
The mining and processing of peridot require specific techniques due to its relatively low hardness on the Mohs scale. Peridot ranks at 6.5 to 7 on the Mohs scale, making it a durable but not exceptionally hard gemstone. This means that it can be susceptible to scratches and abrasions if not handled carefully. Miners and gemologists must take these properties into account when extracting and cutting peridot.
Gemological Properties
Peridot is a unique gemstone with a set of distinct gemological properties that make it highly valued in both historical and modern contexts. Its color, hardness, luster, and other characteristics are essential to understanding its appeal and applications.
Color: The most notable feature of peridot is its vibrant green color, which can range from a yellow-green to a deep olive. This coloration is due to the presence of iron in its chemical composition. The intensity of the green hue can vary depending on the concentration of iron, with higher iron content resulting in a deeper, more saturated green. In gemological terms, the color of peridot is one of its defining characteristics and is often used to distinguish it from other green gemstones such as emerald or topaz.
Hardness: Peridot ranks between 6.5 and 7 on the Mohs scale of mineral hardness. This makes it a relatively durable gemstone, suitable for use in jewelry, but also means that it can be scratched or abraded if exposed to harder materials. Its hardness is comparable to that of quartz, making it a practical choice for everyday wear, though it requires careful handling to maintain its brilliance.
Luster: Peridot exhibits a vitreous (glassy) luster, which enhances its visual appeal. This luster is enhanced by the way the gemstone is cut, with faceting techniques designed to maximize its brilliance and light refraction.
Clarity: Peridot is generally transparent to translucent, with inclusions that can range from visible to nearly invisible. These inclusions are often characteristic of the gemstone and can be used to identify it. High-quality peridot is typically free of significant inclusions that would detract from its appearance.
Cut: Peridot is commonly cut into various shapes, including round, oval, cushion, and emerald cuts. The choice of cut often depends on the shape and size of the rough stone, as well as the desired aesthetic outcome. The cut of a peridot gemstone can significantly influence its brilliance and overall appearance.
Carat Weight: Peridot is available in a wide range of carat weights, from small stones used in earrings and pendants to larger stones suitable for rings and other statement pieces. The availability of peridot in various sizes makes it a versatile gemstone for different types of jewelry.
