History and Lore
Peridot's history is as rich and complex as its color. Known as the "gem of the sun," it was highly revered by the ancient Egyptians, who believed it held protective powers and could ward off the terrors of the night. The name "Peridot" is derived from the Arabic word "faridat," which means gem. This etymology reflects the gemstone's widespread use and appreciation across different cultures and eras.
In ancient Egypt, Peridot was often found in the volcanic glass known as obsidian, which was mined on the island of Zabargad in the Red Sea. This island, also known as St. John’s Island, was a primary source of Peridot for the Egyptians and was considered a sacred place. The gemstone was used in jewelry and amulets, believed to bring prosperity and good fortune to its wearer.
Peridot's journey through history is marked by its association with various cultures and its use in different contexts. In medieval Europe, it was sometimes mistaken for emerald due to its similar color, and it was used in religious artifacts and royal regalia. For example, the Shrine of the Three Holy Kings in Cologne Cathedral is adorned with Peridot, which was previously thought to be emerald. This misidentification highlights the gemstone's visual similarity to other precious stones and its value in historical contexts.
In addition to its use in jewelry and religious artifacts, Peridot has also been associated with metaphysical properties. It is believed to enhance spiritual connection and trust, making it a popular choice for those seeking inner clarity and balance. The gemstone is also associated with the energy of friendship, symbolizing the importance of positive relationships and mutual support.
Geological Formation and Sources
Peridot is a gem-quality variety of the mineral olivine, which is a silicate mineral with a chemical composition of (Mg,Fe)₂SiO₄. The presence of iron in the crystal structure gives Peridot its characteristic green color. The gemstone is formed under extreme conditions, often in the hardened lava that carries it from deep within the Earth's mantle. This formation process results in Peridot being found in igneous rocks, particularly those that have undergone rapid cooling.
One of the most fascinating aspects of Peridot is its extraterrestrial origin. It has been found in meteorites, which have traveled from outer space. These meteoritic Peridots are formed in the same way as their terrestrial counterparts but under the unique conditions of space. The discovery of Peridot in meteorites has provided valuable insights into the geological processes that occur in the universe and has expanded our understanding of the gemstone's formation.
Peridot is primarily sourced from a few key locations around the world. The island of Zabargad in the Red Sea, once known as Topazios, is one of the most famous sources. Other notable sources include the United States, particularly in states such as Arizona and Hawaii, where Peridot is found in basaltic lava flows. Other countries that produce Peridot include China, Brazil, and Pakistan. These diverse sources contribute to the availability of Peridot in the global market and ensure that it remains a popular gemstone.
The mining of Peridot involves a combination of traditional and modern techniques. In areas where Peridot is found in lava flows, miners often use surface mining methods to extract the gemstone. This process involves removing the overlying rock and soil to access the Peridot deposits. In some cases, underground mining is also used, particularly in areas where the Peridot is found in deeper geological formations.
Once extracted, Peridot is cut and polished to enhance its natural beauty. The gemstone is typically cut in a variety of shapes, including round, oval, and cushion cuts, depending on the desired aesthetic and the properties of the rough stone. The cut of Peridot is designed to maximize its brilliance and color, making it a visually stunning gemstone.
Gemological Properties
Peridot is a gemstone with distinct physical and optical properties that make it a popular choice for jewelry and other decorative uses. The following table summarizes the key gemological properties of Peridot, based on the information provided in the sources:
