For those born on August 20th, peridot is the gemstone that symbolizes their birthdate. Known as the “gem of the sun,” peridot has captivated civilizations for millennia with its vibrant green hue and unique gemological properties. This article delves into the rich history, geological formation, symbolic meaning, and practical uses of peridot, providing a comprehensive guide for gemstone enthusiasts, jewelry buyers, and students of gemology.
History and Lore
Peridot has a long and storied history that dates back at least 1500 B.C. It was first mined by the ancient Egyptians on the island of Zabargad (now known as St. John’s Island) in the Red Sea. The Egyptians revered peridot as the “gem of the sun,” believing it to harness the power of their sun god, Ra. The island of Zabargad, which means “emerald island” in Arabic, was a primary source of peridot for the Egyptian civilization. Miners worked under the guidance of a high priest, as it was believed that the gemstone was a gift from the sun god.
Beyond Egypt, peridot has been found in various historical and cultural contexts. In medieval Europe, peridot was often worn by knights and warriors for protection and strength. The gemstone was also used in religious artifacts, such as the Shrine of the Three Holy Kings in Germany’s Cologne Cathedral, which features 200 carats of what were once believed to be emeralds—later identified as peridot. Some historians speculate that Cleopatra’s famed emerald collection may have actually consisted of peridot, highlighting the gemstone’s historical misidentification and widespread appeal.
Peridot has also been associated with celestial phenomena. It is one of the few gemstones that can be found in meteorites, as it forms under extreme conditions deep within the Earth’s mantle and is carried to the surface by volcanic activity. This connection to both Earth and space adds to the gemstone’s mystique and allure.
Geological Formation and Sources
Peridot belongs to the olivine mineral family and is formed under extreme heat and pressure deep within the Earth’s mantle. It is typically found in volcanic rocks and is carried to the surface through magma. Peridot is also found in meteorites, making it one of the few gemstones that have traveled from outer space.
The gemstone’s color is due to its intrinsic composition, specifically the presence of iron. Unlike many gemstones, peridot’s color is not caused by impurities but is a result of its chemical makeup. This gives peridot a unique and consistent color range, from lime green to olive green, with some variations in tone and saturation.
Peridot is found in several countries around the world. Major sources include India, China, Pakistan, Myanmar, and the United States. In the U.S., peridot is commonly found in the lava fields of Hawaii and the mines of Kashmir. The gemstone’s presence in these diverse locations underscores its geological versatility and the conditions under which it can form.
The gemstone’s hardness on the Mohs scale ranges from 6.5 to 7, making it relatively durable but still requiring care when worn in jewelry. Peridot can be found in a variety of colors, with the most common being lime green, olive green, and yellow-green. These variations are influenced by the amount of iron in the gemstone’s composition.
Gemological Properties
Peridot is a gemstone with distinctive and well-defined gemological properties. Its chemical formula is (Mg,Fe)₂SiO₄, and it belongs to the silicate mineral group. The gemstone’s refractive index ranges from 1.65 to 1.70, and it has a specific gravity of approximately 3.3 to 4.3. Peridot is singly refractive, meaning it does not exhibit double refraction, and it has a vitreous luster.
One of the most notable characteristics of peridot is its color. The gemstone’s green hue is caused by the presence of iron in its chemical structure. The intensity of the green color can vary, with the most prized peridot exhibiting a rich, vivid green tone. Peridot is also known for its transparency, with high-quality stones being clear and free of inclusions. However, some peridot may contain small inclusions or fractures, which can affect its clarity and value.
Peridot is cut into a variety of shapes, including round, oval, and cushion cuts. The choice of cut depends on the gemstone’s natural shape and the desired aesthetic. Peridot is often set in jewelry such as rings, pendants, earrings, and bracelets. Its relatively high hardness makes it suitable for everyday wear, but it should still be protected from impacts and harsh chemicals to maintain its appearance.
Symbolism and Metaphysical Beliefs
Peridot has been associated with a range of symbolic and metaphysical meanings across different cultures and historical periods. In ancient Egypt, peridot was believed to bring protection, prosperity, and emotional healing. It was also thought to ward off negative energies and promote inner peace. The gemstone’s connection to the sun made it a symbol of warmth, energy, and vitality.
In modern times, peridot continues to be associated with these qualities. It is often worn to attract prosperity and good fortune, as well as to enhance emotional balance and stability. The gemstone’s green color is also linked to the heart chakra in many spiritual traditions, symbolizing love, compassion, and emotional healing. Wearing peridot is believed to help individuals stay grounded while pursuing their goals and to remain open to the love and positivity that surrounds them.
Peridot is also associated with friendship, passion, and renewal. It is considered a gemstone that promotes trust and clarity in relationships, making it a popular choice for gifts that celebrate friendships and new beginnings. The gemstone’s warm and vibrant energy is thought to stimulate creativity and confidence, making it a powerful tool for personal growth and self-expression.
Care and Cleaning
Due to its relatively high hardness on the Mohs scale, peridot is a durable gemstone, but it still requires proper care to maintain its appearance and longevity. Peridot should be protected from impacts and abrasions, as it can chip or fracture if subjected to rough handling. It is also sensitive to high temperatures and should be kept away from direct heat sources.
To clean peridot jewelry, it is recommended to use a soft, lint-free cloth and a mild detergent solution. Ultrasonic and steam cleaners can also be used, but they should be used with caution, as some peridot may contain inclusions or fractures that could be damaged by excessive vibration or heat. After cleaning, peridot should be dried with a soft cloth and stored in a cool, dry place to prevent tarnishing or discoloration.
When wearing peridot jewelry, it is advisable to avoid exposure to harsh chemicals, such as household cleaners or perfumes, which can dull the gemstone’s luster. Peridot should also be removed during activities that involve physical contact or the risk of impact, such as sports or manual labor.
Conclusion
Peridot is a gemstone with a rich history, unique geological properties, and powerful symbolic meaning. For those born on August 20th, peridot serves as a radiant reminder of the sun’s energy, the earth’s strength, and the spirit of renewal. Its vibrant green color and intrinsic composition make it a gemstone of both beauty and significance, cherished by civilizations for thousands of years.
