The Egyptians called it the “gem of the sun” and believed it harnessed the power of their sun god, Ra. They also thought it could protect the wearer from night terrors and evil spirits.
In the ancient world, Peridot was highly valued for both its beauty and its symbolic significance. The Romans used it in jewelry and believed it brought success, peace, and good luck.

These beliefs have contributed to Peridot's enduring appeal and have helped shape its role as a meaningful gemstone in various cultures.

However, for those born specifically on August 20th, Peridot holds a special significance. It is believed to enhance natural qualities such as passion and clarity, and it is considered a symbol of friendship and emotional healing.
Geological Formation and Sources
Peridot is a mineral known as olivine and is formed deep within the Earth's mantle. It is brought to the surface through volcanic activity, where it is found in igneous rocks. What makes Peridot unique is that its color is not due to impurities, as is the case with many other gemstones, but rather its intrinsic composition. The intensity of the green color in Peridot depends on the amount of iron present in the crystal structure.
Peridot is typically found in volcanic rocks and is relatively common compared to other gemstones. Despite its abundance, high-quality Peridot that is suitable for jewelry is less common. The finest Peridot is usually found in the United States, specifically in Arizona, where it is mined from basaltic rock. Other notable sources include Egypt, Myanmar, and New Mexico.
Gemological Properties
Peridot is a gemstone with distinct and identifiable properties that make it a favorite among gemologists and jewelry enthusiasts. It has a hardness of 6.5 to 7 on the Mohs scale, which makes it relatively soft compared to other gemstones like diamonds or sapphires. This hardness means that Peridot is suitable for use in jewelry but requires careful handling to avoid scratches and damage.
The gemstone's refractive index is high, which contributes to its bright, sparkling appearance. Peridot is known for its vibrant green color, which ranges from yellow-green to deep olive green. Unlike many other gemstones, Peridot occurs in only one color—green—making it unique in the world of colored gemstones.
Peridot is also known for its high clarity. While inclusions are common in natural gemstones, Peridot is often found with few visible inclusions, especially when compared to other gemstones. This clarity, combined with its rich color and high refractive index, makes Peridot a popular choice for use in rings, necklaces, earrings, and bracelets.
