Known in ancient times as the “Gem of the Sun,” peridot has been valued for its beauty and symbolic significance across various civilizations. The ancient Egyptians were among the earliest known cultures to revere peridot, often referring to it as the “Evening Emerald” due to its brilliant green color. They believed that peridot carried the power of the sun and used it in jewelry and amulets to harness its protective and healing properties.
In medieval Europe, peridot was also highly esteemed. It was commonly used in church ornaments and royal regalia, often mistaken for emerald due to its similar green hue. The Shrine of the Three Holy Kings in the Cologne Cathedral, for instance, is adorned with peridot stones that were once thought to be emeralds. This historical misidentification highlights the gemstone’s striking appearance and the high regard in which it was held.
In more recent times, peridot has maintained its allure as a birthstone. It was officially recognized as the August birthstone in 1912 by the American National Association of Jewelers. However, peridot’s significance as a birthstone for August 18th is particularly notable, as it is often associated with specific dates within the month. This recognition underscores its importance in both historical and modern contexts.
Peridot has also been linked to various cultural beliefs and practices. Ancient miners in Egypt and other regions believed that peridot was formed from solidified sunlight and that it brought good fortune to those who wore it. Some cultures even used peridot as a protective talisman against nightmares and negative energies. These beliefs reflect the gemstone’s deep-rooted symbolism and its role in both spiritual and practical aspects of life.
The gemstone’s journey from ancient civilizations to modern times is a testament to its enduring appeal. Whether worn as a personal talisman, a piece of jewelry, or a symbol of protection and renewal, peridot continues to captivate those who encounter it. Its rich history and cultural significance make it a truly remarkable gemstone that resonates with people across different eras and traditions.
Geological Formation and Sources
Peridot is a gem variety of the mineral olivine, which is a magnesium iron silicate. Its unique green color is due to the presence of iron in its chemical composition. Peridot forms under extreme geological conditions, typically in the Earth’s mantle and in meteorites that have traveled from outer space. This makes peridot one of the few gemstones that can be found both on Earth and in extraterrestrial materials.
The formation of peridot begins deep within the Earth’s mantle, where high temperatures and pressures cause the crystallization of olivine. As magma rises to the surface, it cools and solidifies, allowing peridot to form within igneous rocks such as basalt and peridotite. This process is responsible for the majority of the peridot found on Earth. In addition to terrestrial sources, peridot can also be found in meteorites that have fallen to Earth. These meteorites are believed to have formed in the early solar system, and the peridot within them is a rare and fascinating example of extraterrestrial gemstone formation.
Peridot is mined in several locations around the world, each with its own unique geological characteristics. The United States is one of the primary sources of peridot, particularly in the state of Arizona, where it is found in basaltic lava flows. Other notable sources include Brazil, China, Egypt, India, and Pakistan. Each of these regions contributes to the global supply of peridot, ensuring that this beautiful gemstone remains accessible to jewelers and gemstone enthusiasts alike.
The geological formation and sources of peridot highlight its extraordinary origin and the natural processes that create this vibrant gemstone. Whether formed deep within the Earth or carried to our planet from outer space, peridot’s formation is a testament to the powerful forces that shape our world and beyond.
Gemological Properties
Peridot is a gemstone with distinct gemological properties that contribute to its beauty and durability. As a gem variety of the mineral olivine, peridot has a chemical composition of (Mg, Fe)₂SiO₄, with the presence of iron responsible for its characteristic green color. This iron content also makes peridot sensitive to heat and chemical treatments, which can affect its appearance and stability.
The hardness of peridot is measured on the Mohs scale, a standard used to determine the scratch resistance of minerals. Peridot has a hardness range of 6.5 to 7, which places it in the category of moderately durable gemstones. This hardness level means that peridot is suitable for use in jewelry, particularly in rings and pendants, but it requires careful handling to avoid scratches and damage. Compared to other gemstones, peridot is relatively soft, so it is important to consider its durability when designing and wearing jewelry featuring this gemstone.
Peridot has a refractive index range of 1.65 to 1.69, which is relatively high and contributes to its brilliance and fire. This refractive index allows light to enter and reflect within the gemstone, creating a lively and sparkling appearance. The high refractive index also enhances the gemstone’s transparency, making it appear clear and vibrant.
In terms of specific gravity, peridot has a range of 3.30 to 3.40, which is relatively high for a gemstone. This density gives peridot a substantial feel, adding to its visual and tactile appeal. The combination of its refractive index and specific gravity results in a gemstone that is both visually striking and physically dense.
Peridot is typically found in a range of green colors, from pale yellow-green to deep olive green. This color variation is due to the differing amounts of iron in the gemstone’s composition. The most valuable and sought-after peridot stones are those with a rich, vibrant green color, as these are the most visually appealing and rare. Peridot is also known for its lack of pleochroism, meaning it does not display different colors when viewed from different angles. This uniformity in color enhances its appeal as a gemstone.
The gemological properties of peridot make it a unique and captivating gemstone. Its moderate hardness, high refractive index, and specific gravity contribute to its beauty and durability, while its vibrant green color and uniformity in appearance make it a popular choice for jewelry and gemstone collections.

This belief in peridot’s protective qualities was so strong that it was often used in amulets and jewelry to safeguard the wearer from harm.
The ancient Egyptians also linked peridot to the sun, believing that it carried the essence of sunlight and could bring good fortune and prosperity. This connection to the sun and its life-giving energy contributed to peridot’s nickname as the “Gem of the Sun.” In medieval Europe, peridot continued to be valued for its protective and healing properties. It was often used in church ornaments and royal regalia, where it was believed to provide spiritual and physical protection to those who wore it.
In addition to its protective qualities, peridot has been associated with emotional healing and renewal. Modern interpretations of peridot’s symbolism suggest that it can help individuals overcome stress, anxiety, and emotional turmoil. It is believed to promote a sense of well-being and harmony, making it a popular choice for those seeking emotional balance and inner peace.
Peridot has also been linked to the concept of growth and transformation.
