Peridot is the gem variety of the mineral olivine, and its journey from volcanic formations and meteorites to jewelry showcases its extraordinary origin.
This article will explore the historical significance of peridot, its geological formation and sources, its gemological properties, the symbolism and metaphysical beliefs associated with it, and practical tips for caring for peridot jewelry. By the end, readers will have a comprehensive understanding of why peridot remains a beloved gemstone, especially for those born in August.
History and Lore
Peridot has a long and storied history that dates back to ancient civilizations. It was first discovered and used by the ancient Egyptians, who mined it from the volcanic island of Zabargad in the Red Sea. The island, known in ancient times as Topazios, was the primary source of peridot for centuries. The name "peridot" is derived from the Arabic word "faridat," meaning "gem," highlighting its value in the ancient world.
In ancient Egypt, peridot was believed to possess protective qualities and was used as a talisman to ward off nightmares and evil spirits. It was also associated with the sun and was thought to bring positive energy and vitality to the wearer. The ancient Egyptians even called it the "Gem of the Sun," a name that reflects its bright and cheerful color.
During the Middle Ages, peridot continued to be highly valued in Europe. It was often used in religious and royal jewelry, appearing in the adornments of priests and the chalices of churches. In medieval Europe, peridot was believed to offer protection and was worn by clergy as a symbol of purity and divine favor.
The gemstone also played a role in the jewelry of the Victorian era, where it was frequently incorporated into intricate designs. Its popularity waned in the 20th century but has since experienced a resurgence due to its unique color and relatively affordable price compared to other gemstones like rubies or sapphires.
One of the most intriguing aspects of peridot’s history is its connection to Hawaiian mythology. According to legend, the goddess Pele, the deity of volcanoes, was said to have cried green tears of fire, which fell to the earth and solidified into peridot. This myth adds a layer of cultural richness to the gemstone, linking it to the volcanic activity that helped form it in the first place.
Geological Formation and Sources
Peridot is formed under extreme geological conditions, primarily in volcanic environments and meteorites. It is the only gemstone that can be found in both terrestrial and extraterrestrial sources, making it a truly unique gem.
The most common source of peridot is volcanic lava flows, where it forms in the molten rock of the Earth’s mantle. As the lava cools and solidifies, peridot crystals can develop. It is also found in metamorphic rocks, particularly in areas where the Earth’s crust has been subjected to intense heat and pressure.
Peridot is primarily composed of iron and magnesium, and its chemical formula is Mg₂SiO₄ to Fe₂SiO₄, depending on the ratio of iron to magnesium. This composition is what gives peridot its distinctive green color. The more iron present in the crystal, the deeper the green hue.
Peridot can be found in various parts of the world, including:
- China
- Myanmar
- Pakistan
- Tanzania
- Vietnam
- The United States
- The Red Sea island of Zabargad
- Hawaii
Some of the most notable peridot deposits are located in Arizona, where the Peridot Beach on the island of São Tomé and the San Carlos Apache Reservation are known for producing high-quality stones.
Peridot has also been found in meteorites, which adds to its mystique. In fact, some of the finest peridot samples have been retrieved from space, making them truly out-of-this-world gems.
Gemological Properties
Peridot is a silicate mineral with a hexagonal crystal structure. It is known for its glassy luster and transparency, which can range from translucent to transparent. Its refractive index is between 1.65 and 1.69, and it has a birefringence of 0.036, which means it can exhibit double refraction when viewed through a loupe or microscope.
One of the most notable gemological properties of peridot is its hardness, which is 6.5 to 7 on the Mohs scale. While this is relatively high, it is not as hard as diamonds or corundum (sapphires and rubies), which means it can be scratched by harder materials. Therefore, peridot jewelry should be handled with care to avoid damage.
Peridot is also known for its pleochroism, which means it can display different colors when viewed from different angles. While most peridot appears in a uniform green color, it can sometimes show a slight yellow or brownish hue depending on the lighting.
Another interesting property of peridot is its fluorescence. Some peridot samples can exhibit weak fluorescence under ultraviolet light, which can affect their appearance in different lighting conditions.
Peridot is typically free of inclusions, making it a clean and attractive gemstone. However, some stones may contain small, visible inclusions that do not detract from their overall beauty.
Symbolism and Metaphysical Beliefs
Peridot has long been associated with positive energy, protection, and clarity of mind. In ancient times, it was believed to be a stone of protection, shielding the wearer from negative energy, illness, and evil spirits. It was also used as a dream stone, helping people overcome nightmares and anxiety.
In modern times, peridot is often associated with healing, growth, and renewal. It is believed to help with emotional balance, inner strength, and mental clarity. Some people use peridot to calm their minds, reduce stress, and enhance their focus.
Peridot is also linked to abundance and success, making it a popular choice for those seeking to improve their financial situation or career prospects. It is believed to attract positive opportunities and help the wearer make wise decisions.
In terms of chakra work, peridot is associated with the solar plexus chakra, which is linked to self-confidence, personal power, and digestion. It is believed to help activate this chakra, promoting a sense of empowerment and self-worth.
Peridot is also used in jewelry for healing purposes, particularly in pendants and rings. Wearing peridot is thought to help absorb negative energy and reinforce positive intentions.
Care and Cleaning
Because peridot has a hardness of 6.5 to 7 on the Mohs scale, it is relatively durable but still requires careful handling to avoid damage. It is not resistant to heat, so it should not be exposed to high temperatures, such as those found in steam cleaners or ultrasonic cleaners. Heat can cause peridot to fracture or change color.
Peridot is not sensitive to light, so it can be worn or displayed in various lighting conditions without fading or discoloration. However, it should be kept away from harsh chemicals, such as ammonia, bleach, or acid, which can damage its surface or alter its color.
To clean peridot jewelry, it is recommended to use mild soap and warm water. A soft cloth or a jewelry brush can be used to gently remove dirt and debris. Avoid using abrasive materials or harsh chemicals, as these can scratch or damage the stone.
When storing peridot, it should be kept separate from harder gemstones, such as diamonds or corundum, to prevent scratches. It is best to store peridot in a soft pouch or a jewelry box with individual compartments.
If peridot is being worn regularly, it is a good idea to inspect it periodically for signs of wear or damage. Any loose settings or cracked stones should be addressed by a professional jeweler to ensure the longevity of the piece.
Conclusion
Peridot, the vibrant green birthstone for August, is a gemstone with a rich history, fascinating geological origins, and deep symbolic meaning. Its connection to ancient civilizations, its formation in volcanic and extraterrestrial environments, and its association with positive energy and protection make it a truly unique gemstone.
From its use in ancient Egyptian jewelry to its modern-day popularity in contemporary designs, peridot continues to be a beloved gemstone for those born in August. Its relatively affordable price and wide availability make it an accessible choice for jewelry lovers, while its durability and beauty ensure that it can be enjoyed for generations.
