Peridot, the radiant green gemstone associated with the month of August, has long captivated jewelers, collectors, and wearers alike. Known for its sunny, olive-green hue and its association with positive energy and vitality, peridot holds a unique place in the world of gemstones. As one of the most affordable and widely available precious gemstones, it is also highly versatile in jewelry design, making it a popular choice for rings, pendants, and earrings. This article explores the rich history of peridot, its geological properties, its cultural and symbolic significance, and practical advice for caring for and styling peridot rings.
History and Lore
Peridot's history is as fascinating as its color. The gemstone has been known and cherished for thousands of years, with evidence of its use dating back to ancient civilizations. The name "peridot" is derived from the French word "perit," meaning "to pass through," and is believed to refer to the way the stone was transported from the Red Sea island of Zabargad, a key source of the gem in antiquity.
In ancient times, peridot was often found in volcanic lava flows, particularly in the islands of St. John and Zabargad. These locations were the primary sources of the gemstone, and the mineral was highly valued for its vibrant color and supposed protective powers. The Egyptians referred to peridot as the "gem of the sun," believing that it was formed from the fire of the sun and was particularly effective in warding off nightmares and evil spirits.
During the Middle Ages, peridot was often mistaken for topaz, due to its similar golden-green color. This misidentification persisted for centuries, and it was not until the 19th century that gemologists were able to accurately distinguish peridot from topaz. In fact, peridot was once considered the only precious gemstone found in the United States, as it was discovered in the 18th century in the state of Arizona.
Peridot was also used in religious contexts. In the 19th century, a discovery of peridot in a cathedral in England led to the belief that the gemstone had been used as a symbol of Christ's Passion. As a result, peridot was incorporated into religious jewelry and was worn by clergy and laity alike as a symbol of faith and purity.
Today, peridot is recognized as the official birthstone for August and is often given as a gift to celebrate birthdays or as a token of friendship and affection. Its association with the sun and its positive energy make it a symbol of warmth, optimism, and renewal, which is why it is especially popular during the summer months.
Geological Formation and Sources
Peridot is a mineral composed of magnesium iron silicate, with the chemical formula (Mg, Fe)₂SiO₄. It is a member of the olivine mineral group, which is characterized by its high refractive index and strong pleochroism, meaning that the stone can display different colors when viewed from different angles. Peridot's color ranges from yellow-green to deep olive green, depending on the iron content within the crystal structure.
The gemstone is formed in the Earth's mantle and brought to the surface through volcanic activity. It is commonly found in basaltic lava flows and in meteorites, which is one of the reasons why peridot is sometimes referred to as "the gemstone from the stars." In fact, some of the most beautiful and highly valued peridots have been found in meteorites, such as the ones from the Allende meteorite in Mexico.
Today, peridot is mined in a variety of locations around the world. The primary sources include:
- Zabargad Island (St. John Island): Located in the Red Sea, this island has been a key source of peridot for centuries. The gemstone found here is known for its rich green color and high quality.
- Arizona, USA: Peridot is one of the few precious gemstones found in the United States and is a state gemstone of Arizona. The gemstone is mined from basalt rock formations in the state.
- Sri Lanka: Known for its gemstone-rich terrain, Sri Lanka is a significant source of high-quality peridot.
- Brazil, China, and Norway: These countries also produce peridot, though in smaller quantities compared to the primary sources.
The availability of peridot in various parts of the world has made it a relatively affordable and accessible gemstone. Unlike diamonds or colored gemstones such as rubies and sapphires, peridot is not subject to the same level of market scarcity, which contributes to its popularity in jewelry design.

Peridot is a relatively durable gemstone, with a hardness of 6.5 to 7 on the Mohs scale. This means it can withstand everyday wear, though it is not as hard as diamonds or sapphires. It is also sensitive to heat and sudden temperature changes, which can cause it to crack or lose its luster. Therefore, it is important to avoid exposing peridot to extreme temperatures or using harsh chemicals when cleaning it.
Another notable characteristic of peridot is its cleavage. The gemstone has a perfect cleavage in one direction, which means it can be split along a specific plane if struck with enough force. This property makes it important to handle peridot with care, especially when setting it in jewelry.
Symbolism and Metaphysical Beliefs
Peridot has been associated with various metaphysical and symbolic meanings throughout history. In many cultures, it is believed to bring positive energy, clarity, and emotional balance. Ancient Egyptians, for example, believed that peridot could ward off nightmares and was a powerful protective stone. They often wore it as a pendant or placed it under their pillows to ensure peaceful sleep.
In medieval Europe, peridot was thought to have healing properties and was used to treat ailments of the stomach and liver. It was also believed to protect against poison and to enhance one's vitality and strength. These beliefs persisted well into the Renaissance, when peridot was incorporated into amulets and talismans for protection and good fortune.
Modern crystal healers and practitioners of gemstone therapy continue to attribute peridot with a range of positive properties. It is often used to promote emotional healing, especially in cases of grief or loss. Peridot is believed to help individuals release negative emotions and to encourage self-acceptance and inner peace. It is also associated with the heart chakra and is said to support love, compassion, and forgiveness.
In terms of symbolism, peridot is often associated with the sun, warmth, and vitality. It is considered a stone of joy and optimism, and is believed to help individuals stay positive even in difficult times. This is why it is particularly popular during the summer months and is often given as a gift to celebrate birthdays, anniversaries, and other special occasions.
Care and Cleaning of Peridot Rings
Proper care and maintenance are essential to preserving the beauty and longevity of peridot rings. While peridot is a relatively durable gemstone, it is still sensitive to certain conditions and requires gentle handling. Below are some practical tips for caring for and cleaning a peridot ring:
Gentle Cleaning
The safest way to clean a peridot ring is with a soft brush, warm water, and a mild dish soap. Gently scrub the stone and setting, rinse thoroughly, and pat dry with a soft, lint-free cloth. This method is effective for removing everyday dirt and grime without damaging the gemstone or the metal setting.
Avoid Harsh Chemicals
Peridot should be kept away from harsh chemicals, such as household cleaners, chlorine, and perfumes. These substances can dull the stone's brilliance and potentially damage the metal over time. It is recommended to remove the ring before using any of these products.
Proper Storage
When not in use, peridot rings should be stored in a separate pouch or a lined jewelry box to prevent scratches from harder gemstones like diamonds. This helps protect both the peridot and the metal setting from damage.
Avoid Extreme Temperatures
Peridot is sensitive to extreme temperature changes and should not be exposed to high heat or sudden temperature shifts. This includes avoiding the use of ultrasonic cleaners and steam cleaners, which can cause the gemstone to crack or lose its luster.
Stacking and Everyday Wear
Peridot can be stacked with other rings, but care should be taken to avoid abrasive materials that could scratch the stone or its setting. When choosing metals to pair with peridot, yellow gold and white gold are excellent choices due to their ability to complement the gemstone's color.
Styling and Choosing the Perfect Peridot Ring
When selecting a peridot ring, it is important to consider both personal style and practicality. Peridot's vibrant green color makes it a versatile gemstone that can be paired with a variety of metals and styles. Yellow gold enhances the warm, golden-green tones of peridot, while white gold or platinum provides a striking contrast that highlights the gemstone's brilliance.
Peridot rings can be styled in a number of ways, depending on the occasion and the wearer's preferences. For a more classic look, a simple solitaire peridot ring with a yellow or white gold band is an excellent choice. For a more modern and elegant style, peridot can be set in a halo design with small diamonds or other gemstones surrounding the central stone.
Peridot can also be paired with other gemstones to create unique and eye-catching designs. For example, a peridot ring set with diamonds or other green gemstones like emeralds can create a beautiful and balanced look that is both stylish and meaningful.
When it comes to everyday wear, peridot rings are best suited for individuals who lead an active lifestyle but still want to enjoy the beauty of fine jewelry. The gemstone's durability makes it suitable for daily wear, but it is still important to handle it with care to avoid any potential damage.
