History and Lore
Peridot has a storied past that spans millennia. The gemstone has been cherished by various cultures, each attributing unique meanings and powers to it. Ancient Egyptians referred to peridot as the "gem of the sun" and believed it to be a gift from the gods, often using it in their jewelry and religious artifacts. The Romans, too, held peridot in high regard, incorporating it into their adornments and even mistakenly identifying it as emerald.
In medieval Europe, peridot was often confused with other green gemstones, including topaz and emerald. This misidentification led to many historical treasures being discovered to contain peridot instead of the more highly valued stones. For example, the Shrine of the Three Holy Kings in Cologne Cathedral, which was thought to contain emeralds, was later found to be adorned with peridot. This highlights the gemstone's historical significance and its sometimes unexpected appearances in notable collections.
Peridot has also found its way into popular culture and historical events. It was reportedly part of Cleopatra’s famous emerald collection, adding to its allure and mystique. The gemstone’s association with friendship and its role in enhancing communication and interpersonal connections has made it a beloved choice for jewelry throughout the ages.
Geological Formation and Sources
Peridot is a type of olivine, a mineral composed primarily of magnesium and iron silicate. Its formation occurs deep within the Earth's mantle, where intense heat and pressure cause the mineral to crystallize. Volcanic activity then brings peridot closer to the Earth's surface, where it can be mined. This unique geological process results in the gemstone's vibrant green color, which varies depending on the iron content within the stone.
In addition to terrestrial sources, peridot can also be found in meteorites, making it one of the few gemstones with extraterrestrial origins. This celestial connection adds another layer of fascination to the gemstone, as it is literally a piece of the universe brought to Earth.
Some of the most notable sources of peridot include:
- Arizona, USA: Known for producing high-quality peridot, Arizona is one of the leading sources of the gemstone in the United States.

- Madagascar: This island nation is a key producer of peridot, offering a range of colors and qualities.
The geological characteristics of peridot, including its hardness and refractive properties, make it a desirable gemstone for jewelry. However, due to its relatively low hardness compared to other gemstones, it requires careful handling and maintenance to preserve its beauty.
