History and Lore
Peridot has a rich and storied history that dates back thousands of years. The gemstone is believed to have been one of the first gemstones to be used by ancient civilizations, with evidence of its use found in Egypt as early as 1500 BCE. The ancient Egyptians called peridot the "gem of the sun," believing that it was a gift from the sun god, Ra. They often used it in jewelry and amulets to protect against nightmares and the evil eye.
One of the most intriguing aspects of peridot’s history is its association with the sun. Because of its glowing green color and its tendency to radiate light, peridot was thought to hold the power of the sun. This belief contributed to its use in religious and ceremonial contexts, where it was worn as a protective talisman. In some traditions, peridot was also believed to promote peace, clarity, and emotional balance.
Peridot’s connection to the sun is further reinforced by the fact that it can be found in meteorites. In rare cases, peridot has been discovered in extraterrestrial rocks, making it one of the few gemstones that originate both on Earth and in space. This cosmic origin has added to its mystique and has made it a symbol of otherworldly energy and protection.
In addition to its historical significance, peridot has also been associated with personal growth and renewal. In many cultures, it is believed that peridot encourages the wearer to embrace change, let go of negativity, and grow in both mind and spirit. For those born on August 23rd, peridot is seen as a stone of transformation and self-discovery, helping individuals to unlock their full potential and live with purpose.
Geological Formation and Sources
Peridot is a gemstone that forms deep within the Earth’s mantle, where extreme heat and pressure create the conditions necessary for its formation. It is a variety of the mineral olivine, which is composed of magnesium iron silicate. The green color of peridot is due to the presence of iron in its chemical structure, and the intensity of the green hue varies depending on the amount of iron present.
Unlike most other gemstones, which form in the Earth's crust, peridot originates in the mantle, where it is brought to the surface by volcanic activity. When magma rises and cools, it can carry peridot crystals with it, depositing them in areas where they can be mined. This process can take millions of years, resulting in the formation of gem-quality peridot crystals.
Peridot is found in several parts of the world, with some of the most notable sources including:
- Zabargad Island (St. John’s Island), Egypt: This is one of the most famous sources of peridot and has been mined for centuries. The island was a major supplier of peridot to the ancient Egyptians and continues to be an important source today.
- Arizona, USA: The United States is one of the largest producers of peridot, particularly in Arizona. The gemstone is often found in basaltic rock formations and is mined in areas such as the San Carlos Apache Reservation.
- Brazil: Brazil is another significant source of peridot, with large deposits found in the state of Minas Gerais. The peridot from Brazil is known for its high quality and vibrant color.
- Madagascar and Myanmar: These countries also have notable peridot deposits and are important contributors to the global supply of the gemstone.
The rarity of high-quality peridot varies depending on the source. Stones with a rich, deep green color and minimal inclusions are considered the most valuable, and these are typically found in smaller quantities. Peridot is generally more affordable than other gemstones of similar size and quality, making it a popular choice for jewelry and collectors.
Gemological Properties
Peridot is a gemstone with distinct physical and optical properties that contribute to its beauty and durability. As a member of the olivine family, it has a unique crystal structure and a range of characteristics that set it apart from other gemstones.
Physical Properties
- Chemical Formula: (Mg, Fe)₂SiO₄
- Crystal System: Orthorhombic
- Hardness: 6.5 to 7 on the Mohs scale
- Specific Gravity: 3.30 to 4.55
- Refractive Index: 1.65 to 1.85
- Cleavage: Distinct, in three directions
- Color: Yellow-green to olive green
- Transparency: Transparent to translucent
The hardness of peridot, which ranges from 6.5 to 7 on the Mohs scale, means that it is relatively durable but not as hard as gemstones like diamonds or sapphires. This makes it suitable for everyday wear, although care should be taken to avoid impact or exposure to harsh chemicals, which can cause damage.
Peridot has a refractive index that ranges from 1.65 to 1.85, which gives it a moderate level of brilliance. When cut and polished, peridot can display a lively and vibrant appearance, especially under artificial light. This is one of the reasons why peridot is sometimes referred to as the “Evening Emerald,” as it tends to glow under low-light conditions.
One of the most notable features of peridot is its distinct cleavage. Cleavage refers to the way a mineral breaks along planes of weakness, and peridot has cleavage in three directions. This means that it is somewhat fragile and can be prone to chipping if struck with force. As a result, it is important to handle peridot jewelry with care, especially when cleaning or setting the stones.
Optical Properties
Peridot is known for its vibrant green color, which is due to the presence of iron in its chemical structure. The color can range from a pale yellow-green to a deep olive green, depending on the amount of iron present. Stones with a higher iron content tend to have a more intense and desirable color.
The color of peridot is also known for its stability. Unlike some gemstones that may fade or change color over time, peridot retains its rich green hue even after years of wear. This makes it an excellent choice for jewelry that is worn regularly.
Another unique optical property of peridot is its ability to glow under artificial light. This characteristic makes it particularly attractive in evening settings and adds to its allure as a gemstone.

Care and Cleaning
Proper care and maintenance are essential for preserving the beauty and longevity of peridot jewelry. Due to its moderate hardness and distinct cleavage, peridot requires some special attention to ensure that it remains in good condition over time.
Cleaning Peridot Jewelry
Peridot can be cleaned using mild soap and warm water. A soft cloth or a soft-bristled brush can be used to gently scrub the stone and remove any dirt or grime. It is important to avoid using harsh chemicals or ultrasonic cleaners, as these can damage the gemstone.
When cleaning peridot, it is also important to avoid exposing it to sudden temperature changes. Rapid changes in temperature can cause the stone to crack or become damaged, especially if it is exposed to extreme heat or cold.
Storing Peridot Jewelry
To prevent scratches and damage, peridot jewelry should be stored in a soft, padded container or a jewelry box with individual compartments. It is best to store peridot separately from other gemstones, as harder stones can scratch the surface of the peridot.
When not in use, peridot jewelry should be kept in a cool, dry place away from direct sunlight and sources of heat. This will help to prevent any fading or discoloration of the gemstone.
Wearing Peridot Jewelry
Peridot is a relatively durable gemstone, but it is not as tough as some other gemstones like diamonds or sapphires. This means that it is best suited for jewelry that is worn with care, such as necklaces, earrings, and pendants. Rings can also be made with peridot, but they should be handled with care to avoid impact or damage.
When wearing peridot jewelry, it is important to avoid activities that may cause the stone to be subjected to impact or pressure. This is especially important for rings, which are more likely to be exposed to physical stress.
