History and Lore of Peridot
Peridot’s history is as colorful as the gemstone itself. Revered for centuries in cultures across the globe, it has been associated with divine light, earthly abundance, and even cosmic protection. Ancient Egyptians referred to peridot as the “gem of the sun” and called it the “stone of Ra,” believing it was a sacred gift from the gods. It was often used in sacred rites and ceremonial jewelry, adorning the pharaohs with its warm green luster. Some legends claim that it was the only gemstone that could be worn safely at night, as its brilliance did not summon evil spirits or nightmares.
In medieval Europe, peridot was often mistaken for emerald and was also linked to healing properties. It was used in amulets and talismans for its protective qualities, particularly against witchcraft and nightmares. Sailors and warriors alike carried peridot into battle, trusting in its ability to provide strength and courage. During the Renaissance, peridot was frequently set into religious artifacts and royal regalia in Italy and Germany, where it continued to symbolize purity and divine favor.
In the world of astrology, peridot is associated with both Leo and Virgo, two of the most influential zodiac signs. For those born in late July through early August, the stone is believed to bring clarity of thought and a balanced perspective, making it a powerful stone for those with a natural curiosity and social charm. For Virgo, born in late August to early September, peridot is said to enhance practicality, loyalty, and the capacity for self-improvement.
Modern times have seen a resurgence in peridot’s popularity. In 2016, as part of the updated list of official birthstones, the American National Association of Jewelry Wholesalers added peridot, spinel, and sardonyx as the official August birthstones. While peridot remains the most recognized symbol for the month, the inclusion of its counterparts highlights a growing appreciation for the diversity and beauty of gemstones.
Peridot also has a deep connection to the idea of renewal and personal growth. It is a gemstone associated with summer festivals and is even used in some traditions to mark the 16th anniversary of marriage, symbolizing the warmth of a long-lasting relationship and the blossoming of love over time.
Geological Formation and Sources of Peridot
Peridot has a unique origin among gemstones. Unlike most, which form within the Earth's crust, peridot is created in the Earth's mantle at depths of approximately 30 to 50 miles. Only diamonds are known to form at comparable depths. The high temperatures and pressures of the mantle cause the crystallization of forsterite, the gem-quality form of the mineral olivine, which gives peridot its signature green color.
Volcanic activity plays a crucial role in bringing peridot from deep within the Earth to the surface. As magma rises, it carries with it fragments of the mantle, including peridot crystals, which become embedded in the cooled and solidified igneous rock, typically basalt. This process allows peridot to be collected at or near the Earth’s surface, where it can be mined and cut into the gemstones we see in jewelry.
One of the most intriguing aspects of peridot is its extraterrestrial origin. In rare cases, peridot has been found in meteorites, such as the Jepara meteorite discovered on the island of Java. These are olivine-rich pallasite meteorites, and their presence suggests that peridot can also form in space under similar high-pressure and high-temperature conditions. For those interested in the cosmic connections of gemstones, this extraterrestrial origin gives peridot a particularly special allure.
In terms of geographical distribution, peridot is found in a number of locations around the world. Some of the most notable sources include:
Arizona and Utah (United States): Peridot is abundant in the basalt rock of the American Southwest, especially in the area near San Carlos. The U.S. is one of the most accessible sources of high-quality peridot for collectors and cutters.
India and Pakistan: The regions of Kashmir and Afghanistan are known for producing fine, olive-green peridot. Indian peridot typically appears a bit darker in tone, while the stones from Pakistan are often more yellow-green.
Myanmar and Kenya: These countries also yield small quantities of top-grade peridot, prized for their clarity and vibrant color.
Because peridot is relatively abundant in high-quality and is accessible in several locations, it is considered a more affordable gemstone compared to other birthstones, even while maintaining a high level of desirability among jewelry lovers.
Gemological Properties of Peridot
Peridot is distinguished by a set of unique and identifiable gemological properties that help expert gemologists identify it by sight, touch, and even under a microscope. Here are the essential details that characterize this extraordinary gemstone:
Color: Peridot is known for its exclusively green coloration, varying from pale yellow-green to deep olive green. The depth and tone of the color depend on the iron content within the forsterite crystal structure.
Hardness: On the Mohs scale, peridot ranks at 6.5–7. While this is moderately hard, it is still softer than many other commonly used gemstones (such as rubies and sapphires), so it requires careful handling and suitable settings to avoid scratching or chipping.
Chemical Composition: Peridot is composed of a magnesium iron silicate compound with the chemical formula (Mg, Fe)₂SiO₄. The varying amount of iron in the structure is responsible for the different shades of green.
Refractive Index: Peridot has a refractive index of 1.65–1.69, which means it bends light in a way that gives the stone its notable brilliance and sparkle. It has a conchoidal fracture, similar to glass, and is isotropic—meaning it has no detectable doubling of inclusions when viewed under magnification.
Clarity and Inclusions: Peridot is often found with inclusions, but unlike in diamonds, these inclusions do not necessarily reduce the gem’s value. In many cases, the presence of small inclusions is considered natural and a testament to the gem's authentic origin.
Luster: Peridot possesses a vitreous (glass-like) luster, which contributes to its bright and lively appearance when polished.
Cutting and Shapes: Peridot is typically cut in shapes that enhance its fire and color, such as round brilliant, emerald, or cushion cuts. Its clarity and light dispersion make round and oval cuts particularly effective at highlighting its natural beauty.
These properties make peridot not only more affordable but also highly versatile in jewelry design, allowing it to be worn in a wide variety of styles.
Symbolism and Metaphysical Beliefs
The symbolism of peridot is as rich as its vibrant color. For centuries, this gemstone has been associated with a wide range of positive energies and healing properties, making it a favorite in the world of metaphysical practices.
Love and Longevity: Peridot is believed to foster sincere and lasting love, making it a meaningful gift for romantic partners or cherished friends. Its protective qualities are also thought to extend to relationships, reinforcing loyalty and devotion.
Transformation and Renewal: Due to its association with the sun and the summer season, peridot is seen as a powerful stone for personal growth, transformation, and new beginnings. It is often recommended for those going through major life transitions or seeking motivation and clarity.
Healing and Protection: Historically, peridot has been used as a protective amulet against nightmares and negative energy. Modern crystal healing practices continue to value it as a stone of emotional balance and cleansing. It is believed to help dispel fear and negativity, bringing forth optimism and joy.
Abundance and Prosperity: Many cultures believe peridot brings good fortune, particularly in matters of wealth and success. It is often gifted to entrepreneurs or those with ambitions in business as a token of encouragement and prosperity.
In the practice of chakra work, peridot is associated with the solar plexus and heart chakras. It is thought to bring clarity to the mind, enhance personal power, and encourage compassionate connections with others.
While these metaphysical attributes have deep cultural significance, they are not scientifically verified. However, the enduring belief in peridot's healing and protective qualities attests to its deep-seated place in human history and spiritual traditions.
Care and Cleaning of Peridot
Given that peridot is a relatively soft gemstone with a hardness of 6.5–7 on the Mohs scale, it requires careful handling to maintain its brilliance and longevity. Here are some recommended practices for peridot care and cleaning:
Avoid Harsh Chemicals: Do not use cleaning agents that contain strong acids or abrasive compounds, as these can dull the gem’s surface or damage the jewelry setting. Ammonia-based or bleach-based solutions should be avoided.
Use Mild Soap and Warm Water: A mild dish soap and warm water are ideal for cleaning peridot jewelry. Gently swirl the jewelry in the soapy water, using a soft-bristled brush to remove dirt and oils.
Rinse and Dry Thoroughly: After cleaning, rinse the gemstone under lukewarm water to remove any soapy residue. Dry it with a soft, lint-free cloth to prevent water spots.
Avoid Ultrasonic Cleaners: Although convenient, ultrasonic cleaners vibrate at a frequency that can potentially harm peridot. The vibrations may loosen the settings or crack the gemstone, especially if it has inclusions.
Proper Storage: To prevent scratches and damage, store peridot in a soft pouch or separate compartment in a lined jewelry box. Avoid stacking it with harder gemstones like diamonds or sapphires, which can cause scratches.
Repolishing Over Time: Over extended periods of wear, the luster of peridot may dull. A professional jeweler can gently repolish it to restore its original shine.
By following these simple care tips, peridot jewelry can remain vibrant and beautiful for many years, making it a cherished and lasting addition to any collection.
