Peridot, the vibrant green gemstone celebrated as the August 14th birthstone, holds a unique place in the world of gemology. Known for its luminous hue and historical significance, Peridot has been cherished across cultures and epochs. From ancient Egyptian beliefs to its modern role in jewelry, this gemstone combines scientific intrigue with cultural resonance.
This article explores the rich history, geological formation, gemological properties, and symbolic meaning of Peridot. We also discuss its use in jewelry and how to care for this delicate gemstone.
A Historical Gemstone of Light and Protection
Peridot has a storied past that spans millennia. Its earliest mentions date back to ancient Egypt, where it was revered as the “gem of the sun.” The Egyptians believed Peridot possessed protective powers and used it in their jewelry and amulets. According to some sources, the gem was said to glow under moonlight and was believed to ward off evil spirits and nightmares. This belief led to the stone being used in amulets worn at night to ensure peaceful sleep.
In medieval Europe, Peridot was considered a symbol of healing and purity. It was often used in religious artifacts and was associated with the sun, light, and the power of renewal. Some historians speculate that Cleopatra’s famed emerald collection may have actually been composed of Peridot, given the similarities in appearance and the historical sources of the gem in the Red Sea.
During the Renaissance, Peridot was sometimes confused with emerald due to its rich green color. This misidentification led to its inclusion in some of the most famous historical pieces, such as the Shrine of the Three Holy Kings in Cologne Cathedral, which features what were believed to be emeralds but are now recognized as Peridot.
Geological Formation and Sources
Peridot is a form of the mineral olivine and is typically found in volcanic rocks and meteorites. Its green color is due to the presence of iron within its chemical structure. The gemstone is formed deep within the Earth's mantle, where it is brought to the surface through volcanic activity or meteorite impacts.
One notable source of Peridot is the island of Zabargad, also known as St. John’s Island, located in the Red Sea. This island has been a historical source of Peridot since ancient times. Another significant source is Hawaii, where Peridot has been found in volcanic lava flows. Additionally, Peridot has been discovered in meteorites, making it one of the few gemstones that can be found both on Earth and in space.
Peridot is relatively abundant compared to other gemstones, but its availability varies depending on the quality and size of the stones. High-quality Peridot with a vibrant green color and minimal inclusions is particularly sought after in the jewelry market.
Gemological Properties of Peridot
Peridot is known for its distinct green color and its unique gemological properties. Below is a detailed overview of its key characteristics:
| Property | Details |
|---|---|
| Chemical Formula | (Mg,Fe)₂SiO₄ |
| Color | Ranges from yellowish green to greenish yellow, with the most prized stones displaying a rich, vivid green. |
| Hardness (Mohs Scale) | 6.5–7.0 |

Peridot is one of the few gemstones that occurs in only one color—green—making it unique among other gems. Its hardness of 6.5–7.0 on the Mohs scale means it is relatively durable but still requires careful handling to avoid scratches and chips, especially along its cleavage planes.
The gemstone’s refractive index contributes to its brilliance and sparkle when cut properly. Peridot is often cut in a variety of shapes, including round, oval, emerald, and cushion cuts, depending on the desired aesthetic and the stone’s natural inclusions.

Peridot has long been associated with positive energy, prosperity, and protection. In ancient times, it was believed to bring good fortune and happiness to its wearer. The gemstone was also thought to have healing properties and was used to treat ailments such as fever and digestive issues.
In modern times, Peridot continues to be valued for its symbolic meanings. It is often associated with renewal, growth, and transformation. The gemstone is believed to help release negative emotions, promote optimism, and enhance one’s ability to forgive and heal. Some people also believe that Peridot can aid in communication and help individuals express their thoughts and feelings more clearly.
Peridot is also considered a stone of light and is often used in meditation and spiritual practices. It is believed to help cleanse the aura and promote a sense of inner peace. In some traditions, Peridot is used to attract abundance and success, making it a popular choice for those seeking to manifest their goals.
Peridot in Jewelry
Peridot’s vibrant green color and relatively affordable price make it a popular choice for jewelry. It is commonly used in rings, necklaces, earrings, and bracelets. Its versatility allows it to be paired with a variety to metals, including gold, silver, and platinum, as well as other gemstones.
One of the most popular uses of Peridot in jewelry is in rings. The gemstone’s color makes it an eye-catching centerpiece, and it is often paired with diamonds or other gemstones to create a balanced and elegant design.

Peridot is also used in bracelets, particularly those designed for daily wear. Its symbolism of protection and positivity makes it a meaningful choice for those seeking to carry a source of good energy with them throughout the day.

Due to its relatively low hardness and perfect cleavage, Peridot requires careful handling and cleaning to maintain its beauty and durability. The gemstone is susceptible to scratches and chips if not treated properly.
When cleaning Peridot, it is best to use a soft cloth and mild soap with warm water. Ultrasonic cleaners should be avoided, as they can potentially damage the stone by causing vibrations along its cleavage planes. Steam cleaners are also not recommended for Peridot.
