Peridot, the vivid green gemstone designated as the August birthstone, carries a rich tapestry of history, symbolism, and aesthetic appeal. Known for its enchanting hues ranging from deep olive-green to bright lime, peridot is a mineral that has captivated civilizations for millennia. Beyond its visual allure, peridot is celebrated in various cultures for its supposed metaphysical properties and its role in jewelry design. This article explores the geological properties of peridot, its historical significance, and its contemporary use in jewelry, particularly as part of August birthstone jewelry sets.
Introduction
Peridot is one of the few gemstones that occur in only one color—green. This singular coloration is due to the presence of iron within its chemical composition. As the birthstone for August, peridot is associated with themes of growth, prosperity, love, loyalty, and protection. In modern jewelry, peridot is often incorporated into sets that include pendants, earrings, bracelets, and rings, each designed to highlight the gemstone’s natural beauty. Whether worn as a personal adornment or given as a meaningful gift, peridot jewelry sets are a popular choice for those celebrating an August birthday.
The gemstone’s journey into the world of jewelry and birthstones has been shaped by its geological formation, cultural significance, and the ethical considerations of its sourcing. Today, peridot is not only valued for its aesthetic qualities but also for its role in promoting sustainable and ethical jewelry practices.
History and Lore
Peridot has a long and storied history, with references dating back to ancient civilizations. The earliest known use of peridot can be traced to ancient Egypt, where it was referred to as the “gem of the sun.” In Egyptian culture, peridot was believed to possess protective powers and was often used in amulets and talismans. The gemstone was particularly associated with the sun god Ra, and it was believed to bring warmth, vitality, and positive energy to its wearer.
In medieval Europe, peridot was sometimes confused with emeralds due to its green color. This led to some historical inaccuracies, including the misidentification of peridot in various royal collections. Despite these misunderstandings, peridot remained a valued gemstone, often used in religious and ceremonial jewelry.
One of the most intriguing aspects of peridot's history is its connection to volcanic activity. The gemstone is often found in areas where lava flows have cooled, and it is believed that peridot is formed under high-pressure and high-temperature conditions deep within the Earth's mantle. This geological process gives peridot its unique color and clarity.
In more recent times, peridot has gained popularity as a birthstone and as a symbol of personal expression. Jewelry designers and jewelers have embraced peridot for its vibrant color and versatility, incorporating it into a wide range of styles, from classic solitaires to modern, avant-garde designs.
Geological Formation and Sources
Peridot is a silicate mineral composed primarily of iron and magnesium. Its chemical formula is (Mg,Fe)₂SiO₄, and it belongs to the olivine mineral group. The gemstone is formed under high-pressure and high-temperature conditions, typically found in igneous rocks such as basalt and peridotite. Peridot is most commonly found in volcanic regions, where it is brought to the surface through tectonic activity.
The color of peridot is determined by the amount of iron present in the crystal structure. Stones with higher iron content tend to have a darker, more olive-green hue, while those with lower iron content appear more yellow-green. This variation in color makes peridot a versatile gemstone, suitable for a wide range of jewelry designs.
Peridot is mined in various parts of the world, with significant deposits found in the United States, Egypt, China, Brazil, and Pakistan. In the United States, the state of Arizona is particularly known for its high-quality peridot. The gemstone is also found in Hawaii, where it is sometimes referred to as “Hawaiian peridot” due to its association with the island’s volcanic landscape.
Sustainable and ethical sourcing of peridot has become an important consideration in the jewelry industry. Many jewelry companies now prioritize responsible mining practices and environmental sustainability. For example, some jewelers use recycled metals and ethically sourced gemstones to reduce the environmental impact of their products.
Gemological Properties
Peridot is a relatively durable gemstone, with a hardness of 6.5 to 7 on the Mohs scale. This makes it suitable for everyday wear in jewelry such as rings, earrings, and bracelets. However, due to its moderate hardness, peridot should be handled with care to avoid scratches and chips. The gemstone is also sensitive to high heat and should not be exposed to extreme temperatures.
Peridot has a refractive index of approximately 1.65 to 1.70, which gives it a bright, lively appearance. It is typically transparent to translucent and is known for its excellent luster when properly cut and polished. The gemstone is often cut into faceted shapes, such as rounds, ovals, and pears, to maximize its brilliance and color.
One of the most distinctive features of peridot is its pleochroism, which means it can display different colors when viewed from different angles. This effect is subtle and adds to the gemstone's visual interest. Peridot is also known for its strong double refraction, which can cause a doubling effect in the gemstone's facets.
In terms of clarity, peridot is generally included, with most specimens containing visible inclusions. These inclusions are often considered part of the gemstone's character and are not considered flaws. High-quality peridot is characterized by its bright color, clarity, and excellent cut.
Symbolism and Metaphysical Beliefs
Peridot has long been associated with various symbolic meanings and metaphysical properties. In ancient times, it was believed to have protective and healing qualities. It was used in amulets and talismans to ward off negative energy and to promote good health and vitality. Some cultures believed that peridot could bring prosperity and success to its wearer.
In modern times, peridot is often associated with themes of growth, renewal, and transformation. It is believed to help individuals overcome negative emotions and to encourage a positive outlook on life. Peridot is also associated with love and loyalty, making it a popular choice for engagement rings and other romantic jewelry.
The gemstone is also believed to have calming properties, helping to reduce stress and anxiety. It is often used in meditation and healing practices to promote emotional balance and inner peace. In some traditions, peridot is considered a stone of the heart, helping to open the heart chakra and foster compassion and understanding.
Care and Cleaning
Due to its moderate hardness, peridot requires careful handling and cleaning to maintain its beauty. The gemstone should be cleaned with a soft cloth and mild detergent, followed by a rinse with lukewarm water. It is important to avoid using harsh chemicals or ultrasonic cleaners, as these can damage the gemstone or its setting.
Peridot should be stored separately from other gemstones to prevent scratches. It is also advisable to avoid exposing peridot to high heat or direct sunlight for extended periods, as this can cause the color to fade over time.
When wearing peridot jewelry, it is best to remove it before engaging in activities that could cause physical contact or impact. This is particularly important for rings, which are more susceptible to damage due to their frequent use.

From its geological origins in volcanic regions to its historical use in ancient civilizations, peridot has played a meaningful role in human culture for centuries. Its unique color and properties make it a popular choice for jewelry, and its association with growth, prosperity, and protection adds to its enduring appeal.
