History and Lore
Peridot has a rich and storied past that spans centuries and cultures. Known as the “sunstone” in ancient times, it was believed to carry the power of the sun and was often worn to ward off nightmares and promote positive energy. In medieval Europe, peridot was a symbol of good health and was commonly used in amulets and talismans. Some sources suggest that peridot was even mistaken for emerald in ancient Egypt, where it was mined from volcanic rocks in the Red Sea region.
The gemstone’s historical significance is further reflected in its association with the month of August. As the birthstone for this month, peridot has long been cherished for its vibrant color and its ability to symbolize renewal and vitality. In many cultures, it is also believed to bring the wearer happiness and to shield them from negative influences.
The pear cut, a relatively modern innovation in gemstone cutting, enhances the natural fire and luster of peridot. This cut is especially popular in jewelry design due to its balance of elegance and visual appeal. Pear-shaped peridot gemstones are often used in pendants, earrings, and rings, making them a favorite choice for those seeking both beauty and symbolism in their jewelry.
Geological Formation and Sources
Peridot is a type of olivine, a mineral composed primarily of magnesium and iron. Its chemical formula is (Mg,Fe)₂SiO₄, and it is typically found in volcanic rocks and meteorites. The gemstone forms under high-pressure and high-temperature conditions in the Earth’s mantle and is brought to the surface through volcanic activity. This unique geological process gives peridot its distinct color, which ranges from yellow-green to deep olive-green, depending on the iron content.
The finest peridot is typically sourced from specific regions known for producing high-quality stones. Historical sources of peridot include the islands of Zabargad (St. John’s Island) and other islands in the Red Sea, where it was mined as early as 1500 BCE. Today, major sources of peridot include:
- United States: Arizona is one of the primary sources of fine peridot in the U.S.
- Brazil: Known for producing large, vibrant peridot crystals.
- Australia: A significant source of high-quality peridot.
- Egypt: Still produces some of the finest peridot, especially from historical mines.
- Myanmar (Burma): Known for its rich deposits of peridot.
The pear cut, which is particularly well-suited to the natural shape of peridot crystals, allows for maximum brilliance and showcases the gemstone's unique color and clarity. This cut is especially popular among jewelers who specialize in custom-designed pieces, as it offers both aesthetic appeal and practicality in terms of setting and durability.
