Peridot, with its captivating green hues, holds a prominent place as the birthstone of August. Revered for centuries and imbued with rich cultural significance, this gemstone continues to enchant jewelry enthusiasts worldwide. This article delves into the history, geological origins, gemological properties, and symbolism of peridot, offering a comprehensive overview of this remarkable gem.
Peridot: A Gem with Ancient Origins
Peridot boasts a history stretching back over 3,500 years. Its name is believed to originate from the French word “peritot,” meaning “unclear,” referencing the gem’s sometimes cloudy appearance. Ancient civilizations, including the Egyptians, valued peridot highly. Early examples of the gem have been discovered in ancient Egyptian jewelry, demonstrating its long-standing appeal. The gem was mined on islands and volcanic terrains, including Hawaii, Egypt, and Arizona.
During the Middle Ages, Crusaders brought peridot back to Europe, where it was often mistaken for emeralds due to its vibrant green color. For centuries, this misidentification persisted, adding to the gem’s mystique. Historically, peridot was mined extensively on St. John’s Island near Egypt, but significant deposits were later found in Pakistan and the United States. Today, the San Carlos Reservation in Arizona is a primary source of peridot, yielding brilliant lime-green gems. Additional sources include China, Myanmar, and Vietnam.
Geological Formation and Sources
Peridot is formed in the Earth’s mantle and brought to the surface through volcanic activity. It crystallizes in olivine, a common mineral in mafic and ultramafic rocks. The gem is found in various locations globally, though certain regions are particularly renowned for their peridot production.
Historically, Egypt was a significant source, particularly St. John’s Island. However, modern production is largely dominated by the San Carlos Reservation in Arizona, which produces gems with a vivid lime-green hue. Other notable sources include Pakistan, China, Myanmar, and Vietnam. Spinel, the other August birthstone, is sourced from Vietnam and Myanmar, with red varieties from Myanmar being particularly prized, sometimes rivaling the color intensity of rubies.
Gemological Properties
Peridot and spinel, the two birthstones for August, both exhibit remarkable durability. Both gemstones register an 8 on the Mohs scale of hardness, making them suitable for everyday wear. Peridot’s chemical composition is (Mg, Fe)₂SiO₄, indicating it is a magnesium iron silicate. Spinel, on the other hand, has a chemical formula of MgAl₂O₄.
Peridot is known for its distinctive olive-green to golden-green hues, reminiscent of sunlight on new foliage. While larger peridots are relatively rare, smaller gems are abundant. Spinel displays a broader range of colors, including vivid reds, blues, and other shades. The intense red spinels from Myanmar were historically mistaken for rubies, earning spinel the nickname “the great impostor.”
The following table summarizes key gemological properties:
| Property | Peridot | Spinel |
|---|---|---|
| Chemical Formula | (Mg, Fe)₂SiO₄ | MgAl₂O₄ |
| Mohs Hardness | 8 | 8 |
| Color | Olive Green - Golden Green | Red, Blue, Various |
| Sources | Arizona, Egypt, Pakistan, China, Myanmar, Vietnam | Myanmar, Vietnam |
History and Lore
Peridot has accumulated a wealth of lore and symbolism throughout history. Often referred to as “the gem of the sun,” it was believed to possess healing properties and ward off evil spirits. Ancient Egyptians revered peridot, crafting elaborate jewelry adorned with the gem.
Beyond its historical use, peridot carries specific symbolic meanings. It is believed to represent strength and prosperity, embodying positive energy and new beginnings. Spinel symbolizes revitalization, ambition, and eternal love. Peridot is associated with the 16th wedding anniversary, while spinel is the gemstone for celebrating the 22nd anniversary.
Symbolism and Metaphysical Beliefs
Peridot is often associated with positive energy, prosperity, and new beginnings. Its vibrant green color is thought to symbolize growth, renewal, and abundance. Spinel, with its diverse color range, carries varied symbolic meanings. Red spinel represents vitality and passion, while blue spinel is associated with tranquility and wisdom.
Jewelry and Modern Applications
Peridot and spinel are both popular choices for jewelry, lending themselves to a variety of styles. Peridot’s lush green vibrance adds playful pops of color to earrings, bracelets, necklaces, and rings. It complements both warm and cool metals, such as yellow and rose gold, and looks particularly striking when set in silver.
Spinel’s durability and beauty make it ideal for rings, pendants, and earrings. The availability of spinel in a wide range of colors allows for personalized jewelry designs. Stainless steel bracelets featuring CZ birthstones, including peridot, are also available, offering a durable and stylish option. These bracelets are often made with hypoallergenic surgical-grade stainless steel and coated with 18K gold PVD, ensuring they are non-tarnishing and suitable for sensitive skin.
Care and Cleaning
Due to their hardness of 8 on the Mohs scale, both peridot and spinel are relatively durable gemstones. However, they still require proper care to maintain their brilliance. Avoid exposing the gems to harsh chemicals, ultrasonic cleaners, or extreme temperature changes.
Cleaning can be done with warm, soapy water and a soft brush. Rinse thoroughly and dry with a soft cloth. Regular cleaning will help preserve the gem’s luster and prevent the buildup of dirt and grime.
