August is a month of warmth, energy, and vibrancy—qualities that are beautifully reflected in its birthstone, the peridot. Known for its rich green hue and natural brilliance, peridot has captivated civilizations for thousands of years. As one of the few birthstones that can be found in meteorites, peridot holds a unique place in the world of gemology. In this article, we explore the fascinating history, geological properties, and cultural significance of this remarkable gemstone.
A Rich Historical Legacy
The history of peridot dates back to ancient civilizations, where it was revered for its beauty and believed to possess powerful symbolic and protective properties. The stone was particularly cherished in ancient Egypt, where it was referred to as the “gem of the sun.” According to the SOURCES, the Egyptians mined peridot from the island of Topazios in the Red Sea. This island, later known to the Greeks and Romans, was a significant source of the gemstone during antiquity.
Peridot was often used in the form of beads and was highly valued for its natural radiance. Some historians suggest that Cleopatra’s famous emerald collection may have actually been made up of peridot, as the two stones were frequently mistaken for one another in ancient times. Additionally, the Shrine of the Three Holy Kings in Cologne Cathedral, Germany, is adorned with gems that were once believed to be emeralds but are now identified as peridot.
The name “peridot” itself has an interesting etymology. It comes from the Arabic word faridat, meaning “gem,” which underscores the stone’s esteemed status in the ancient world. By the 18th century, the name “topazion,” which was once used for peridot, was reassigned to the gemstone topaz, further adding to the historical confusion surrounding the identification of this green gem.
In addition to peridot, August is associated with two other gemstones: sardonyx and spinel. Sardonyx has a history that stretches back more than 4,000 years and was used in ancient times for amulets and seals. Spinel, on the other hand, was only recently recognized as an August birthstone in 2016. This reflects how the tradition of birthstones has evolved over time, incorporating new stones as they gain popularity and recognition in the jewelry industry.
Geological Formation and Natural Occurrence
Peridot is a gem-quality variety of the mineral olivine, a magnesium iron silicate with a chemical composition of (Mg,Fe)₂SiO₄. The color of peridot is primarily due to the presence of iron in its crystal structure. The more iron present, the deeper the green color. This means that peridot can range in color from a light yellow-green to a rich, deep olive green.
One of the most fascinating aspects of peridot is that it forms under extreme conditions deep within the Earth’s mantle. It is brought to the surface through volcanic activity, often found in the hardened lava that carried it up from the Earth’s interior. This process means that peridot can sometimes be found in lava deposits and volcanic rock formations.
Peridot is also one of the few gemstones that can be found in meteorites. This extraterrestrial origin adds to its mystique and rarity. The gemstone is occasionally referred to as “Pele’s Tears,” a name inspired by Pele, the Hawaiian volcano goddess. This nickname is used to describe the small, glass-like droplets of molten lava that cool rapidly to form tiny, teardrop-shaped peridot crystals.
In terms of mining locations, peridot is found in several parts of the world. Notable sources include Pakistan, the United States (particularly in Arizona), and Egypt. The Smithsonian Institution houses a particularly notable peridot specimen weighing 100.15 carats, which was mined in Pakistan and has an exceptional vivid green color and brilliance. This gem is part of the National Gem and Mineral Collection in Washington, D.C., and is considered one of the most remarkable examples of the August birthstone.
Gemological Properties and Identification
Peridot has a number of distinct gemological properties that make it identifiable and distinguishable from other green gemstones. Its most notable characteristic is its color, which ranges from yellow-green to olive green. Unlike emerald, which contains inclusions that can affect clarity, peridot is often relatively free of inclusions, making it a highly transparent gemstone.
Peridot has a hardness of 6.5 to 7 on the Mohs scale, which means it is relatively durable but not as hard as diamonds or sapphires. This makes it suitable for use in jewelry but also means that it requires careful handling to avoid scratches or damage. It is also susceptible to heat, which can cause it to lose color or become discolored.
One of the key identifying features of peridot is its refractive index, which ranges from 1.65 to 1.69. This is relatively high, contributing to the gemstone’s brilliance and sparkle. Peridot also has a relatively low specific gravity compared to other gemstones, which can help in its identification.
Unlike many other gemstones, peridot does not require heat treatment or other enhancement methods to achieve its color. Its vibrant green color is natural and occurs as a result of the iron content in its crystal structure. This makes peridot a particularly pure and unaltered gemstone in the world of jewelry and gemology.
Symbolism and Metaphysical Beliefs
Throughout history, peridot has been associated with a range of symbolic and metaphysical properties. In ancient Egypt, it was believed to be a protective stone that could ward off negative energy and bring peace and prosperity to the wearer. It was also believed to promote clarity of thought and emotional balance.
In modern times, peridot continues to be associated with positive energy and emotional well-being. It is often used in jewelry as a symbol of abundance, happiness, and destiny. Those born in August, particularly under the zodiac signs of Leo and Virgo, are believed to benefit from wearing peridot, as it is thought to enhance their natural traits of confidence, creativity, and practicality.
The stone is also believed to have a calming effect on the mind and body, making it a popular choice for meditation and spiritual practices. Some sources suggest that peridot can help in the release of negative emotions and promote a sense of inner peace. These beliefs have contributed to the stone’s enduring popularity in both traditional and modern jewelry.
Peridot is also associated with the heart chakra in some spiritual traditions. It is believed to help open the heart, encouraging love, compassion, and emotional healing. This makes it a particularly meaningful stone for those seeking emotional balance and harmony.
Care and Maintenance
Given its moderate hardness and sensitivity to heat, peridot requires careful handling and regular maintenance to preserve its beauty and integrity. When cleaning peridot jewelry, it is best to use a soft cloth and mild soapy water. Ultrasonic cleaners and steam cleaners can be used with caution, but it is important to avoid exposing the stone to high temperatures, as this can cause it to lose color or become damaged.
Peridot should also be stored separately from harder gemstones like diamonds or sapphires to prevent scratches. When not in use, it is recommended to store peridot in a soft cloth or a jewelry box to protect it from dust and physical contact.
Avoid exposing peridot to harsh chemicals or abrasive materials, as these can damage its surface or alter its color. It is also a good idea to have peridot jewelry professionally inspected and cleaned periodically to ensure its longevity and appearance.
Conclusion
Peridot is a gemstone with a rich history, fascinating geological properties, and enduring symbolic significance. As the birthstone for August, it represents the warmth, energy, and vibrancy of this month.
