The gemstone associated with August 28th is peridot, a captivating green gem celebrated for its vibrant hue and a history steeped in symbolism. This gemstone, a variety of the mineral olivine, has been treasured for centuries, representing renewal, growth, and good fortune. While peridot serves as the primary birthstone for the entire month of August, its significance for those celebrating a birthday on the 28th is particularly noteworthy, embodying a unique blend of beauty and positive attributes. This article explores the history, geological origins, gemological properties, and symbolic meanings associated with this remarkable stone.
History and Lore
Peridot’s history stretches back millennia, with evidence of its use dating back to ancient civilizations. The name “peridot” is believed to originate from the Arabic word “faridat,” meaning “gem,” reflecting its long-held value. Throughout history, it was often confused with other green gemstones, notably emeralds, leading to instances where peridot was misidentified in historical collections. Many “emeralds” adorning medieval European cathedral treasures were, in fact, peridots.
Ancient cultures attributed various magical properties to peridot. It was believed to offer protection against nightmares and evil spirits, fostering a sense of peace and calm in the wearer. Its luminous green color led to associations with the sun, symbolizing energy and the ability to dispel darkness. This connection to light and protection made it a talisman for warriors and a symbol of strength.
The journey of peridot to becoming a modern birthstone is defined by official recognition. Sardonyx was the original traditional birthstone for August. Peridot was added as an official birthstone in 1912 by the National Association of Jewellers (now Jewelers of America), solidifying its status as the primary choice for the month. This recognition was based on the gem's popularity and availability. Later, in 2016, the American Gem Trade Association (AGTA) and Jewelers of America (JA) added spinel to the list of August birthstones. This expansion provided those born in August with a wider spectrum of choices, including the vibrant red and pink tones of spinel, alongside the classic green of peridot and the banded patterns of sardonyx.
Geological Formation and Sources
Peridot is unique in its origin, as it is one of the few gemstones that are formed deep within the Earth's mantle. It is brought to the surface through volcanic activity, often found in rocks known as peridotite. This deep-earth formation contributes to its rarity and the intense green color that is prized by collectors.
The chemical composition of peridot is magnesium iron silicate (Mg, Fe)₂SiO₄. The distinctive green color is due to the presence of iron. The specific shade can vary depending on the iron content, ranging from a light olive to a deeper, more intense green. This variation allows for a range of styles, from subtle to bold.
Historically, peridot has been mined in several locations around the world. Ancient sources include Egypt, particularly the island of Zabargad in the Red Sea, which was a significant source for many centuries. Today, peridot is mined in various countries including Pakistan, Arizona (USA), and Mexico. The gem's formation in volcanic environments makes these regions rich in deposits.
Gemological Properties
Understanding the gemological properties of peridot is essential for gem enthusiasts and jewelry buyers. Below is a detailed breakdown of its characteristics:
| Property | Description |
|---|---|
| Mineral Family | Olivine |
| Chemical Formula | (Mg, Fe)₂SiO₄ |
| Color | Green (shades range from yellowish-green to olive to brownish-green) |
| Hardness (Mohs Scale) | 6.5 - 7 |
| Refractive Index | 1.65 - 1.69 |
| Crystal System | Orthorhombic |
| Transparency | Transparent to translucent |
| Luster | Vitreous (glass-like) |
Peridot is considered relatively durable for everyday wear, though it is softer than diamonds, sapphires, or rubies. Its hardness of 6.5 to 7 on the Mohs scale means it can be scratched by materials with a higher hardness rating. Care should be taken to avoid knocks and impacts, as it can be brittle.
Symbolism and Metaphysical Beliefs
Peridot carries a rich tapestry of symbolic meanings. It is widely associated with renewal, growth, and prosperity. The vibrant green color evokes feelings of freshness and new beginnings, making it a popular choice for those seeking to start a new chapter in their lives.
In addition to its association with good fortune, peridot is believed to bring peace and calm to the wearer. Ancient traditions held that it could ward off negative energy and provide protection. Today, many believe that peridot promotes self-respect, willpower, and creativity, particularly when used in meditation or worn as jewelry.
For those born under the sign of Virgo (August 23 – September 22), peridot is one of the Zodiac birthstones. It is believed to align with the personality traits of Virgos, enhancing their natural strengths and bringing balance. Sardonyx, another August birthstone, is associated with the sign of Leo (July 23 – August 22), representing courage and happiness.
Care and Cleaning
To maintain the beauty of peridot jewelry, proper care is essential. Due to its hardness and potential for brittleness, it is advisable to store peridot pieces separately from other jewelry to prevent scratching. When cleaning, use warm, soapy water and a soft brush. Avoid ultrasonic cleaners and steam cleaning, as the gemstone may react to sudden temperature changes.
For daily wear, peridot is suitable for earrings, pendants, and rings that are not subject to heavy impact. With proper care, peridot can retain its vibrant green color and sparkle for generations.
Conclusion
Peridot stands out as a gemstone of remarkable beauty and deep symbolic meaning. From its ancient origins to its modern status as the primary birthstone for August, it has captured the imagination of cultures worldwide. For those born on August 28th, peridot offers a connection to themes of renewal, protection, and prosperity. Whether chosen for its vibrant color, its historical significance, or its metaphysical properties, peridot remains a timeless gem that continues to inspire and delight.
