From its formation deep within the Earth’s mantle and in meteorites to its use in ancient Egyptian jewelry and medieval European treasures, peridot has played a vital role in human history. We will also examine its gemological properties, its role in modern jewelry, and the metaphysical beliefs associated with it.
History and Lore
Peridot’s history is as vibrant and enduring as its color. This gemstone has been known and valued by civilizations for over 4,000 years. Ancient Egyptians, who referred to peridot as the “gem of the sun,” mined it on the Red Sea island of Zabargad, a primary source of the stone until the 20th century. The island was believed to be a sacred place, and the gem was often used in jewelry and sacred artifacts. The Egyptians attributed protective powers to peridot, believing it could ward off nightmares and evil spirits.
During the Middle Ages, peridot was frequently confused with emerald and topaz. This was due to the similar green hues and the lack of advanced gemological techniques to distinguish between them. A notable example of this confusion is the Shrine of the Three Holy Kings in Germany’s Cologne Cathedral, which contains 200 carats of what were thought to be emeralds, but are now known to be peridot. This discovery highlights the gemstone’s historical importance and its widespread use in royal and religious settings.
Peridot also has a connection to the cosmos. It can be found in meteorites that have fallen to Earth from outer space. This extraterrestrial origin adds to the mystique of peridot and supports the belief that it is a stone of cosmic energy and connection.
In ancient cultures, peridot was often associated with the sun. Its bright green color was seen as a symbol of life and vitality. The name “peridot” is believed to come from the Arabic word “faridat,” meaning gem. This linguistic connection reflects the gemstone’s widespread recognition and reverence across cultures and time periods.
The gemstone was also popular in medieval Europe, where it was used in religious and royal jewelry. The vibrant green hue of peridot made it a favorite among jewelers and collectors, who appreciated its beauty and the positive energy it was believed to bring.
Geological Formation and Sources
Peridot is a gem-quality variety of the mineral olivine, which is formed under high-pressure and high-temperature conditions deep within the Earth’s mantle. It is one of the few gemstones that occur naturally in only one color—green—although the shade can vary from yellowish-green to olive to brownish-green, depending on the iron content in the stone.
Peridot is brought to the Earth's surface through volcanic activity. When magma erupts, it carries peridot with it, depositing it in lava flows and volcanic rocks. This process is what allows peridot to be found in certain geological formations. In addition to volcanic sources, peridot can also be found in meteorites that have fallen to Earth. This extraterrestrial origin is a unique characteristic of the gemstone and adds to its allure.
The primary source of peridot historically was the Red Sea island of Zabargad. This island was mined for peridot for thousands of years, and it remained a significant source until the 20th century. Other notable sources of peridot include Arizona in the United States, where peridot is found in basaltic lava flows, and various locations in Africa, Asia, and South America. These regions are known for producing high-quality peridot with vibrant colors and excellent clarity.
Peridot is typically found in igneous rocks, particularly those that have undergone rapid cooling, such as basalt and peridotite. The gemstone’s formation process is a testament to the powerful geological forces that shape our planet and the universe.
Gemological Properties
Peridot is a unique gemstone with distinct gemological properties that make it highly desirable in the world of jewelry and gemology. Its chemical composition is (Mg,Fe)₂SiO₄, and it belongs to the olivine group of minerals. The color of peridot is primarily due to the presence of iron in its composition, which gives it a range of green hues.
The hardness of peridot on the Mohs scale is 6.5 to 7, making it a relatively durable gemstone. However, it is not as hard as diamonds or sapphires, so it requires careful handling and proper care to prevent scratches and damage. Peridot also has a refractive index of 1.65 to 1.70, which contributes to its brilliance and luster.
One of the most distinctive features of peridot is its color. Unlike many other gemstones, which can come in a variety of colors, peridot is known for its singular green hue. The shade of green can vary depending on the amount of iron in the stone, with the most desirable peridots having a vibrant lime-green color. This unique coloration makes peridot stand out in the gemstone world and is one of the reasons it is so highly valued.
Peridot is also known for its pleochroism, a property that allows the gemstone to display different colors when viewed from different angles. This means that peridot can appear to have different shades of green depending on the lighting and the angle at which it is viewed. This optical phenomenon adds to the gemstone’s beauty and complexity.
The cut of peridot is also important in showcasing its beauty. The most common cuts for peridot include the round brilliant cut, the oval cut, and the cushion cut. These cuts help to maximize the gemstone’s brilliance and color. Peridot can also be cut into other shapes, such as emerald cuts and marquise cuts, depending on the desired aesthetic and the gemstone’s natural shape.
In terms of clarity, peridot is typically found with inclusions that are visible to the naked eye. These inclusions are often considered part of the gemstone’s character and can add to its uniqueness. However, peridot with fewer inclusions is generally more valuable and sought after.
Peridot is a popular choice for jewelry due to its vibrant color, durability, and affordability. It is often used in rings, necklaces, earrings, and bracelets. The gemstone’s versatility allows it to be paired with other gemstones and metals, making it a favorite among jewelers and designers.
Symbolism and Metaphysical Beliefs
Peridot has long been associated with positive energy, protection, and prosperity. In ancient cultures, it was believed to have the power to ward off nightmares and evil spirits. The Egyptians referred to peridot as the “gem of the sun,” and they believed it could provide protection and strength. This belief in the gemstone’s protective properties has persisted through the ages and continues to be a part of its symbolism today.
Peridot is also associated with prosperity and success. It is believed to bring good luck and financial success to those who wear it. This makes it a popular choice for those who are looking to attract wealth and abundance. The gemstone’s vibrant green color is also a symbol of growth, renewal, and vitality, making it a powerful stone for those who are seeking new opportunities and fresh beginnings.
In addition to its protective and prosperity-related properties, peridot is also believed to have healing properties. It is said to promote emotional healing and to help individuals release negative emotions such as anger, jealousy, and resentment. This makes it a popular stone for those who are seeking emotional balance and inner peace.
Peridot is also associated with spiritual growth and enlightenment. It is believed to enhance intuition and to help individuals connect with their higher selves.

Peridot is also believed to have a calming effect on the mind and body. It is said to help reduce stress and anxiety and to promote a sense of calm and relaxation. This makes it a valuable stone for those who are dealing with stress and overwhelm in their daily lives.
Care and Cleaning
Due to its relatively low hardness compared to other gemstones, peridot requires careful handling and cleaning to maintain its beauty and longevity. The gemstone has a hardness of 6.5 to 7 on the Mohs scale, which means it can scratch more easily than harder gemstones like diamonds or sapphires. Therefore, it is important to take precautions to prevent damage.
One of the best ways to clean peridot is with a mild soap and warm water solution. Using a soft cloth or a soft-bristled brush, gently scrub the gemstone to remove dirt and debris. It is important to avoid using harsh chemicals or abrasive cleaners, as these can damage the surface of the gemstone.
Peridot should also be stored in a cool, dark place when not in use. Exposure to direct sunlight can cause the gemstone to fade or lose its luster over time. Storing peridot in a soft cloth or a jewelry box with a padded interior can help protect it from scratches and other damage.
When wearing peridot jewelry, it is important to avoid exposing it to harsh chemicals such as household cleaners, perfumes, and lotions. These substances can dull the gemstone’s surface and affect its appearance. It is also a good idea to remove peridot jewelry before engaging in activities that involve physical contact or exposure to abrasive surfaces.
In terms of maintenance, it is recommended to have peridot jewelry professionally cleaned and inspected on a regular basis. A professional jeweler can clean the gemstone using specialized techniques and can also check for any signs of wear or damage. This can help ensure that the gemstone remains in good condition and continues to shine for years to come.
