The gemological properties of peridot—its hardness, chemical composition, and optical characteristics—will also be discussed. Additionally, we will delve into the symbolism and metaphysical beliefs surrounding peridot, as well as how to care for and maintain this beautiful gemstone in jewelry form.
History and Lore
Peridot has a rich and storied history that spans thousands of years. One of the most intriguing aspects of its lore is its ancient association with the sun and its use in various cultures for protective and symbolic purposes. The ancient Egyptians referred to peridot as the “gem of the Sun,” believing that it brought them protection and good fortune. They were known to use peridot in jewelry and amulets, often carving it into intricate designs that reflected their religious beliefs and artistic sensibilities.
The gemstone's presence in historical artifacts is also notable. For example, the Shrine of the Three Holy Kings in the Cologne Cathedral is adorned with peridot gemstones that were initially mistaken for emeralds. This misidentification highlights the gem's striking appearance and the confusion that can arise between different green gemstones. Some historians speculate that Cleopatra’s famous emerald collection may have included peridot, further emphasizing its esteemed status in ancient times.
Peridot also has a unique connection to Hawaiian mythology. The ancient Hawaiians believed that the gemstone was formed from the tears of Pele, the goddess of volcanoes. According to this legend, when Pele wept for her forbidden love, her tears fell to the earth and solidified into beautiful peridot crystals. This narrative adds a layer of cultural significance to the gemstone, linking it to the natural phenomena of volcanic activity and the emotional depth of human experience.
In addition to its historical significance, peridot has been used in various forms of jewelry throughout the ages. Its versatility in color and form has made it a popular choice among jewelers. The gemstone can be found in a wide range of styles, from simple, elegant designs to more elaborate pieces that showcase its vibrant green hue. Its use in jewelry not only reflects its aesthetic appeal but also its cultural importance, as it has been passed down through generations as a symbol of protection and good luck.
Geological Formation and Sources
Peridot is a gem-quality variety of the mineral olivine, which is formed under extreme geological conditions.

In addition to its formation through volcanic activity, peridot can also be found in meteorites that have landed on Earth. These extraterrestrial sources add an intriguing dimension to the gemstone's origin story, as it is one of the few gemstones that can be found beyond our planet. The presence of peridot in meteorites is a testament to its resilience and the unique conditions under which it forms.
The primary sources of peridot are located in several countries, including the United States, China, Brazil, and Egypt. In the United States, peridot is particularly abundant in Arizona, where it is found in volcanic rocks and is often mined for commercial use. This region is known for producing high-quality peridot with vibrant colors that are highly sought after in the jewelry industry.
China is another significant source of peridot, with deposits found in the Xinjiang region. The gemstone from this area is often characterized by its deep green color and excellent clarity, making it a popular choice for jewelry. In Brazil, peridot is found in various locations, and it is known for its excellent color and quality. The gemstone from Brazil is often used in both traditional and modern jewelry designs.
Egypt has a long history of peridot mining, with the gemstone being a part of the country's cultural heritage. The ancient Egyptians were among the first to recognize the beauty and value of peridot, and it has continued to be a significant gemstone in the region. The deposits in Egypt are known for producing peridot with a rich, vibrant green color that is highly prized.
The geological formation of peridot is closely tied to its chemical composition. Peridot is a magnesium iron silicate, with the chemical formula (Mg,Fe)₂SiO₄. The presence of iron in the mineral is what gives peridot its characteristic green color. The amount of iron present can vary, leading to a range of colors from yellow-green to deep olive. This variation in color is one of the factors that make peridot a versatile gemstone, suitable for a wide range of jewelry applications.
Gemological Properties
Peridot is a fascinating gemstone with a unique set of gemological properties that contribute to its beauty and desirability. One of the most notable characteristics of peridot is its hardness on the Mohs scale, which is rated at 6.5 to 7. This hardness makes it relatively durable, allowing it to be used in various types of jewelry, including rings, earrings, and pendants. However, it is still important to handle peridot with care, as it can be susceptible to scratches and chips if exposed to harder materials or improper handling.
The refractive index of peridot ranges from 1.65 to 1.69, which means it has a moderate level of brilliance and sparkle. This optical property contributes to the gemstone's overall appeal, allowing it to catch and reflect light in a way that enhances its vibrant green color. The refractive index also plays a role in how light is transmitted through the stone, creating a beautiful play of light that can be admired in well-cut peridot gemstones.
Peridot is known for its pleochroism, a property that allows it to display different colors when viewed from different angles. This means that a single peridot gemstone can appear to have varying shades of green, depending on the light and the observer's perspective. This characteristic adds depth and complexity to the gemstone, making it even more captivating in jewelry.
The chemical composition of peridot is another crucial aspect of its gemological properties. As a magnesium iron silicate, peridot's color is primarily due to the presence of iron, which imparts the green hue. The amount of iron in the stone can vary, leading to a range of colors from yellow-green to deep olive. This variation in color allows for a wide array of peridot gemstones, each with its own unique character and appeal.
Peridot is also known for its inclusions, which can include small crystals, gas bubbles, and other minerals. These inclusions are often visible to the naked eye and can add to the stone's character, making each peridot gemstone unique. While some jewelers may prefer stones with fewer inclusions for a cleaner look, the presence of inclusions is generally considered a natural and desirable aspect of peridot.
In terms of clarity, peridot is typically found in a range of grades, from included to eye-clean. Eye-clean peridot is highly sought after for its clarity and brilliance, while stones with visible inclusions can still be beautiful and are often used in more casual or rustic jewelry designs. The clarity of peridot can also affect its price, with clearer stones generally commanding higher prices in the market.
The cut of a peridot gemstone is another important factor in its overall appearance. Peridot is often cut into various shapes, including round, oval, and cushion cuts, each of which can enhance the gemstone's brilliance and color. A well-cut peridot will maximize its light reflection and showcase its vibrant green hues. The cut can also influence the gemstone's durability, as certain cuts may be more prone to chipping or damage.
Finally, the carat weight of peridot can vary widely, with gemstones available in sizes ranging from small, delicate stones to larger, statement pieces. The carat weight of a peridot gemstone can affect its price, with larger stones generally being more valuable. However, the price per carat can also be influenced by other factors such as color, clarity, and cut.
Symbolism and Metaphysical Beliefs
Peridot has been associated with various symbolic meanings and metaphysical beliefs across different cultures and historical periods. One of the most prominent associations is its role as a protective gemstone. In ancient times, peridot was believed to ward off nightmares and evil influences, making it a popular choice for amulets and protective charms. This belief was particularly prevalent among the ancient Egyptians, who regarded peridot as a symbol of strength and protection. They often used peridot in jewelry and amulets to harness its protective qualities and to ensure a safe and prosperous life.
In addition to its protective properties, peridot has also been linked to emotional and spiritual healing. It is believed to promote feelings of calmness and serenity, helping individuals to release negative emotions and find inner peace.

Some metaphysical practitioners also believe that peridot can enhance self-confidence and encourage positive thinking, making it a valuable gemstone for personal growth and development.
The gemstone is also associated with abundance and prosperity. In many cultures, peridot is believed to bring good luck and financial success. It is often given as a gift during significant life events, such as birthdays or anniversaries, to symbolize a fresh start and the hope for future prosperity. This belief in peridot's ability to attract abundance has made it a popular choice for those looking to enhance their financial fortunes and achieve their goals.
Peridot has also been linked to the heart chakra in metaphysical practices. It is believed to open the heart chakra, allowing for the free flow of love and compassion. This connection makes peridot a powerful gemstone for those seeking to enhance their relationships and foster deeper connections with others. It is often used in meditation practices to promote emotional healing and to encourage a greater sense of empathy and understanding.
The historical significance of peridot in various cultures further reinforces its symbolic meanings. For example, in Hawaiian mythology, peridot is believed to be formed from the tears of the goddess Pele. This narrative adds a layer of emotional depth to the gemstone, linking it to themes of love, loss, and transformation. The idea that peridot is a gift from the goddess of volcanoes underscores its connection to the earth and the powerful emotions that can arise from natural phenomena.
In modern times, peridot continues to be valued for its symbolic and metaphysical properties.

Peridot is also used in various forms of jewelry, not only for its aesthetic appeal but also for its perceived healing properties. Wearing peridot jewelry is thought to bring about positive changes in one's life, encouraging the wearer to embrace their true self and to live in harmony with their surroundings.
The combination of these symbolic meanings and metaphysical beliefs has contributed to peridot's enduring popularity as a gemstone. Whether used in jewelry, amulets, or as a tool for personal growth, peridot continues to be cherished for its ability to bring about positive change and to promote a sense of balance and harmony in the lives of those who wear it.
Care and Cleaning
To maintain the beauty and longevity of peridot jewelry, it is essential to follow proper care and cleaning practices. As peridot has a hardness of 6.5 to 7 on the Mohs scale, it is relatively durable but still requires gentle handling to avoid damage.

This is particularly important for peridot rings, which are more likely to be exposed to accidental impacts during daily wear.
In addition to regular cleaning and proper storage, it is also essential to have peridot jewelry professionally inspected and cleaned on a regular basis. A professional jeweler can assess the condition of the gemstone and its setting, ensuring that any potential issues are addressed promptly. This is especially important for pieces with intricate settings or delicate designs, as they may require more specialized care.
For those who wish to enhance the brilliance of their peridot jewelry, a professional polishing can be beneficial. A jeweler can use a polishing cloth to restore the gemstone's luster and shine, removing any minor scratches or dullness that may have developed over time. This process should be performed by a professional to avoid any risk of damaging the gemstone.
Finally, it is important to be aware of the environmental conditions that can affect peridot. Exposure to extreme temperatures can cause the gemstone to expand or contract, potentially leading to cracks or other damage. It is best to keep peridot jewelry in a stable environment, away from direct sunlight and sources of heat. This will help preserve the gemstone's integrity and ensure that it remains a cherished piece for years to come.
By following these care and cleaning practices, peridot jewelry can maintain its beauty and value, allowing wearers to enjoy the gemstone's vibrant green hues and rich history for generations to come.
