It is a mineral of extraordinary geological origin, rich cultural history, and profound symbolic meaning. Among its many identities, peridot stands out as a gemstone that is both ancient and modern, mystical and scientific, and most notably, one that is proudly American.
This article explores the multifaceted nature of peridot, delving into its geological formation, its storied historical use across cultures, its spiritual and metaphysical significance, and its role in contemporary jewelry—especially the unique Arizona-mined peridot that has become a symbol of regional pride and ethical craftsmanship. Whether worn as a personal talisman, a meaningful birthday gift, or a statement of environmental and cultural connection, peridot embodies a rare combination of beauty, meaning, and authenticity.
History and Lore
Peridot has a history that stretches back thousands of years, with some of the earliest known records of its use dating to ancient Egypt. The gemstone was mined from the island of Zabargad (formerly known as Topazios), located in the Red Sea. This island, now the most historically significant source of peridot, was known for its harsh conditions and was sometimes referred to ominously as the “Island of Death” or “Ophiodes” (the “Snake Island”). Despite these daunting circumstances, the gemstone mined there was of exceptional quality and was highly prized by ancient civilizations.
In Egypt, peridot was revered not only for its beauty but also for its spiritual significance. The ancient Egyptians believed that peridot had protective properties and could ward off nightmares and negative energies. Priests and royalty wore peridot in their jewelry, believing it to be a symbol of light and purity. This belief extended into medieval Europe, where peridot was often used in the adornment of chalices and church vestments. It was considered a sacred stone, associated with divine power and used in ecclesiastical settings to represent Christ’s light.
The name "peridot" itself comes from the Arabic word faridat, meaning “gem.” This linguistic origin underscores the stone’s long-standing value across different cultures and continents. In medieval Europe, peridot was also used as a protective talisman, believed to shield the wearer from evil spirits and the “terrors of the night.” It was common for travelers and warriors to carry peridot with them, especially during times of uncertainty or conflict.
In the modern era, peridot has continued to hold symbolic and sentimental value. It is the traditional gemstone for the 16th wedding anniversary, symbolizing enduring love and the passage of time. Its role as the August birthstone has also become a meaningful tradition, particularly in Western cultures, where it is often gifted to those born in this month as a symbol of strength, renewal, and the vibrant energy of the sun.
Geological Formation and Sources
Peridot is a type of mineral known as olivine, which is composed of magnesium iron silicate. Its chemical formula, (Mg, Fe)₂SiO₄, determines its color, which ranges from a pale yellow to a deep olive green. The intensity of its green hue depends on the amount of iron in the crystal structure. The higher the iron content, the deeper the green color.
Geologically, peridot is formed deep within the Earth's mantle, often in volcanic environments. It is brought to the surface through volcanic activity, such as the eruption of lava or the movement of tectonic plates. Once exposed, it can be found in basaltic rocks, where it is often embedded in a matrix of dark, glassy material. This process of formation is what gives peridot its natural inclusions—unique features that can be seen under magnification, such as the famous “lily pad” inclusions or delicate “smoke-like veils.”
While peridot is found in several locations around the world, including China, Myanmar, Pakistan, Tanzania, and Vietnam, the most vibrant and ethically sourced specimens come from the United States—specifically from the San Carlos Apache Reservation in Globe, Arizona. This area, known as Peridot Mesa, is one of the most significant and unique sources of peridot in the world.
The mining of Arizona peridot is a labor-intensive and culturally significant process. Most of the mining is done manually, with miners using hand tools such as hammers, chisels, picks, shovels, and rakes to extract the gemstones from open pits. Blasting is rarely used, as it can damage the delicate peridot crystals. The gemstones are then sorted, cleaned, and prepared for cutting and polishing.
What makes Arizona peridot particularly special is its color and clarity. The stones from this region are known for their rich, lime-to-olive green hue, excellent clarity, and consistent quality. These characteristics make Arizona peridot a highly sought-after gemstone in the jewelry industry, especially for those who value both natural beauty and ethical sourcing.
The mining of peridot on the San Carlos Apache Reservation is not just an economic activity but also a cultural one. For generations, members of the tribe have been involved in the harvesting of these precious stones, creating jobs and preserving traditions. The gemstones are mined by hand, and the process is deeply rooted in the history and identity of the Apache people. When worn, Arizona peridot is not just a piece of jewelry but a symbol of the land, the people, and the environment from which it came.
Gemological Properties
Peridot is a relatively durable gemstone, but it is not among the hardest. On the Mohs scale of mineral hardness, peridot ranks between 6.5 and 7, which means it is softer than diamonds, sapphires, and rubies, but harder than quartz and topaz. This moderate hardness makes it suitable for everyday wear in jewelry, though it does require some care to prevent scratches and chips.
In terms of color, peridot is known for its range of green tones, from pale yellow-green to deep olive. The most valuable and sought-after peridot has a rich, saturated green color. This coloration is due to the presence of iron in the mineral’s chemical structure. The more iron the stone contains, the deeper and more vibrant its green appearance.
Clarity is another important factor in the evaluation of peridot. Unlike diamonds, which are prized for their lack of inclusions, peridot is often valued for its visible inclusions, which can add to its character and authenticity. These inclusions, which can include tiny crystals, “lily pad” shapes, or even fragments of natural glass with gas bubbles, are natural and can be seen under magnification. In fact, gemologists and collectors often use these inclusions to identify and appreciate the stone.
Peridot has a refractive index ranging from 1.65 to 1.69, which gives it a moderate level of brilliance and sparkle when cut and polished. The gemstone is also isotropic, meaning that it does not exhibit double refraction, and it has a vitreous (glass-like) luster that enhances its overall appearance.
In terms of cut and shape, peridot is typically cut in brilliant or mixed cuts to maximize its fire and brilliance. However, due to its directional cleavage (a tendency to break along certain planes), it is important for gem cutters to be mindful of the orientation of the stone during the cutting process. Proper cutting can enhance the stone’s color and reduce the risk of damage.
The carat weight of peridot can vary widely, from small accent stones in jewelry to larger center stones. However, because peridot is relatively abundant compared to other gemstones like diamonds or sapphires, it is often more affordable and accessible, especially for larger sizes.
When it comes to ethical sourcing and sustainability, Arizona peridot stands out. Mined by hand on the San Carlos Apache Reservation, it is one of the few gemstones in the world that is ethically and responsibly sourced. The mining process supports local communities and preserves traditional practices, making it an excellent choice for those who prioritize ethical and sustainable gemstone options.
Symbolism and Metaphysical Beliefs
Peridot has long been associated with a wide range of symbolic and metaphysical properties, many of which have been passed down through ancient traditions and continue to influence modern gemstone lore. One of the most enduring beliefs about peridot is its role as a protective talisman. In ancient cultures, it was thought to shield the wearer from nightmares and evil spirits. This belief persisted into medieval Europe, where peridot was used in ecclesiastical jewelry to represent divine light and protection.
In addition to its protective qualities, peridot is also associated with renewal and vitality. Its vibrant green color symbolizes growth, life, and the energy of the natural world. As the birthstone of August, it is often given as a gift to those born in this month as a symbol of strength, resilience, and the ability to adapt and thrive.
Modern metaphysical beliefs also attribute healing properties to peridot. It is considered a stone of emotional balance, helping to reduce stress, anxiety, and negative emotions. Some practitioners believe that peridot can promote calmness, encourage self-awareness, and support emotional healing. It is also thought to aid in the release of old patterns and behaviors, making it a useful stone for personal growth and transformation.
Peridot is also associated with prosperity and abundance. It is believed to attract wealth, success, and positive change in one's life. Some people use peridot in their workspaces or businesses to enhance creativity, attract opportunities, and foster a sense of optimism.
In the realm of astrology, peridot is associated with the Sun and the zodiac signs of Leo and Virgo. It is believed to enhance confidence, self-expression, and inner strength. For those born under the Sun sign, peridot is considered a powerful stone that can help align the wearer with their true purpose and potential.
While the metaphysical properties of peridot are not scientifically proven, they continue to play an important role in the cultural and spiritual significance of the gemstone. Whether worn for its beauty, its symbolism, or its perceived healing properties, peridot remains a deeply meaningful and cherished gemstone.
