Its striking green color, derived from the presence of iron in its mineral composition, makes it a standout in the world of gemstones.

Whether you are a gemstone enthusiast, a jewelry buyer, or simply curious about the meaning behind this radiant stone, this guide will provide a comprehensive overview of one of August’s most treasured birthstones.
History and Lore
Peridot’s history is as rich and colorful as its appearance. The gemstone has been known and valued by various civilizations across the world. Ancient Egyptians referred to Peridot as the “gem of the sun,” and it was commonly used in their jewelry. In fact, some of the most famous Peridot gemstones in history were found in the Isle of Zabargad in the Red Sea, a source that was known to the Egyptians as early as 1500 BCE. This island was the primary source of high-quality Peridot for centuries and was even guarded by priests who believed the gem was a sacred gift from the sun.
The name "Peridot" is believed to have originated from the Arabic word "faridat," which means "gem." This connection highlights the deep historical roots of the stone in the Middle East and its importance in early trade routes. In medieval Europe, Peridot was often used to create pendants and rings, particularly for those born in August. It was also believed to bring protection and ward off negative energies, making it a popular choice for both personal adornment and spiritual practices.
In addition to its historical significance, Peridot has a unique place in modern gemology. It is one of the few gemstones that form in the Earth’s mantle, emerging during volcanic activity. This rare origin adds to its allure and makes it a fascinating subject for both scientists and collectors.
Geological Formation and Sources
Peridot is a gem-quality variety of the mineral olivine, and it is formed under intense heat and pressure deep within the Earth’s mantle. Unlike most gemstones, which form in the Earth’s crust, Peridot is brought to the surface through volcanic eruptions. These eruptions carry magma, and within this molten rock, Peridot crystals can form over millions of years. As the magma cools and solidifies into basalt, the Peridot is deposited, making it accessible to miners.
The presence of iron in Peridot’s chemical composition is what gives it its signature green color. Peridot is composed primarily of magnesium iron silicate, and the amount of iron present determines the shade of green. Stones with a higher iron content tend to have a deeper, more vibrant green, while those with less iron may appear more yellowish. Despite these variations, all Peridot retains its distinctive transparency and brilliance.
Peridot can be found in several parts of the world, including the United States (particularly in Arizona and Hawaii), China, Pakistan, and various regions in Africa and South America. The Isle of Zabargad in the Red Sea remains one of the most historically significant sources of high-quality Peridot. This island, also known as St. John’s Island, was once a key location for Peridot mining and is still regarded as a prime source of the finest specimens.
One of the most fascinating aspects of Peridot is its presence in meteorites. In rare cases, raw Peridot crystals have been found embedded in pallasite meteorites, such as the Jepara meteorite discovered on the island of Java. These extraterrestrial occurrences of Peridot provide further insight into the gem’s formation and add to its mystique.
Gemological Properties
Peridot is a gemstone with a unique set of physical and optical properties that make it both beautiful and valuable. The following are key gemological characteristics of Peridot:
- Color: Peridot is known for its green color, which can range from yellowish-green to deep olive green. This variation is due to the amount of iron in the stone’s composition.
- Hardness: On the Mohs scale of mineral hardness, Peridot ranks between 6.5 and 7. This makes it a relatively durable gemstone, suitable for use in jewelry. However, it is not as hard as diamonds or corundum (such as ruby and sapphire), so it requires careful handling to avoid scratches or chips.
- Clarity: Peridot is typically transparent, with a high degree of clarity. Inclusions are rare and often not visible to the naked eye.
- Luster: Peridot has a vitreous (glassy) luster, which enhances its brilliance and makes it appear especially vibrant under light.
- Cut: Peridot is commonly cut into round, oval, or cushion shapes. These cuts help to maximize the gemstone’s natural brilliance and color.
- Origin: Peridot is formed deep within the Earth’s mantle and is brought to the surface through volcanic activity. It can also be found in meteorites, making it one of the few gemstones that have an extraterrestrial origin.
These properties make Peridot a versatile and attractive gemstone that is both scientifically interesting and aesthetically pleasing.
Symbolism and Metaphysical Beliefs
Peridot is not only admired for its beauty but also for its symbolic and metaphysical significance. Across different cultures and time periods, Peridot has been associated with various meanings and powers. Some of the most notable symbolic associations of Peridot include:
- Friendship and Harmony: Peridot is believed to promote friendship and harmony among people. It is said to enhance positive emotions and foster healthy relationships.
- Healing and Renewal: Peridot is associated with healing and renewal, both physically and emotionally. It is believed to help with recovery from illness and to bring a sense of inner peace and balance.

These beliefs have contributed to the enduring popularity of Peridot as a birthstone and a meaningful gift. Whether worn as jewelry or kept as a personal talisman, Peridot is seen as a powerful and positive stone that can bring joy and protection to the wearer.
Care and Cleaning
Given its relatively high hardness on the Mohs scale, Peridot is a durable gemstone that can be worn regularly. However, to maintain its beauty and longevity, it is important to care for Peridot properly. Here are some tips for cleaning and maintaining Peridot jewelry:
- Avoid Harsh Chemicals: Peridot should not be exposed to harsh chemicals, such as bleach or ammonia, as these can damage the gemstone’s surface and alter its color.
- Warm, Soapy Water: A gentle cleaning solution of warm, soapy water is ideal for Peridot. Simply soak the jewelry in the solution for a few minutes, then use a soft cloth or brush to gently clean the gemstone.
- Ultrasonic Cleaners: Ultrasonic cleaners are generally safe for Peridot. However, it is important to avoid using them if the jewelry has any other delicate or porous gemstones.
- Avoid Extreme Heat: Peridot should not be exposed to extreme heat, as this can cause it to lose its color or become damaged.
- Store Properly: To prevent scratches, store Peridot jewelry in a soft pouch or a separate compartment in your jewelry box. Avoid stacking Peridot pieces on top of one another.
By following these care instructions, you can ensure that your Peridot jewelry remains beautiful and vibrant for years to come.
