History and Lore
Peridot has a storied past that dates back to ancient civilizations. In ancient Egypt, it was known as the "gem of the sun" and was believed to protect its wearer from the terrors of the night. This belief was so deeply rooted in Egyptian culture that Peridot was often used in jewelry and religious artifacts. The Romans, who were equally captivated by its beauty, referred to it as the "evening emerald" because of its vibrant green color that remained visible even under artificial light.
The use of Peridot as a birthstone is not a modern concept. The gem has been associated with August for over 4,000 years. It was officially recognized as one of the birthstones for August in 1912 by the American Gem Trade Association (AGTA). However, it wasn't until 2016 that Spin and Sardonyx were added to the list of August birthstones, giving those born in this month a wider selection of gems to choose from. This addition reflects the evolving preferences of the jewelry industry and the desire to offer more options in terms of color, affordability, and availability.
The historical significance of Peridot extends beyond its use in ancient Egypt and Rome. In medieval Europe, Peridot was believed to have protective properties and was often worn as an amulet to ward off nightmares and negative energies. It was also associated with good health and vitality. These beliefs have persisted in various forms through the centuries, contributing to the gemstone's enduring appeal.
In the modern era, Peridot continues to be cherished for its beauty and symbolism. It is often chosen as a gift to celebrate August birthdays and is a popular choice for jewelry that reflects the energy and warmth of summer. The gemstone's association with light and transformation makes it a meaningful symbol for those who wear it.
Geological Formation and Sources
Peridot is a gemstone formed under extreme conditions. It is the yellowish green to greenish yellow gem variety of the mineral olivine. The formation of Peridot is a fascinating process that involves the cooling of magma and the presence of specific chemical elements. Olivine, the mineral from which Peridot is derived, is composed of magnesium, iron, and silicon dioxide. The presence of iron in the mineral gives Peridot its distinctive green color.
The gemstone is often found in the hardened lava that carried it from deep within Earth’s mantle. This unique formation process means that Peridot can be found in areas with volcanic activity. In addition to terrestrial sources, Peridot has also been discovered in meteorites that traveled from outer space. This extraterrestrial origin adds to the gemstone's allure and makes it one of the few gemstones with a cosmic connection.
Peridot is found in various locations around the world. Some of the most notable sources include:
- United States: The state of Arizona is particularly well known for its Peridot deposits. The gemstone is often found in basaltic lava flows and is mined from these geological formations.
- Egypt: The island of Zabargad, located in the Red Sea, is one of the most famous sources of Peridot. This island has been a source of the gemstone for thousands of years and is often referred to as the "Peridot Island."
- Australia: Peridot is also found in Australia, where it is mined from volcanic rocks.
- Russia: The Ural Mountains in Russia are another source of Peridot. The gemstone is found in metamorphic rocks in this region.
- Brazil: Brazil is another significant source of Peridot. The gemstone is found in various geological formations across the country.
The availability of Peridot from these diverse sources ensures that the gemstone is relatively abundant and accessible. This abundance contributes to its affordability, making it a popular choice for jewelry. Despite its availability, high-quality Peridot with a vivid green color and excellent clarity is still considered a valuable gemstone.
