For those born on August 2nd, the birthstone is Peridot, a gemstone celebrated for its distinctive vibrant green hue and a history stretching back to ancient civilizations. This gem, often associated with light, warmth, and good fortune, holds a unique place in both the geological world and the realm of symbolism. This article will delve into the origins, properties, history, and significance of Peridot, exploring its journey from the Earth’s mantle to adornment in jewelry.
History and Lore
Peridot’s history is rich and often intertwined with misidentification. Throughout history, it was frequently confused with other green gemstones, notably emeralds. Many “emeralds” adorning medieval European cathedral treasures were, upon later examination, revealed to be Peridots. The name “peridot” itself is believed to originate from the Arabic word “faridat,” meaning “gem,” highlighting its long-held value.
Ancient civilizations revered Peridot. Known as the “gem of the sun,” it was linked to light and abundance. Its use as a talisman against evil spirits is also documented, demonstrating its protective qualities in ancient beliefs. More recently, Peridot has become traditionally associated with the celebration of a 16th wedding anniversary, symbolizing the enduring nature of a lasting relationship.
Geological Formation and Sources
Peridot’s formation is unique among gemstones. Unlike most gems that form in the Earth’s crust, Peridot originates deep within the Earth’s mantle, forming over millions of years. This makes it a rare and fascinating gem, with diamonds being the only other gem commonly formed at such depths. Volcanic activity brings these Peridot crystals to the surface, depositing them in volcanic rocks and the debris of ancient eruptions.
Currently, significant sources of Peridot are found in several locations worldwide. The United States is a notable producer, alongside Myanmar, Pakistan, and China. Remarkably, Peridot has even been discovered embedded within pallasitic meteorites, such as the Jepara meteorite found on the island of Java, further emphasizing its extraterrestrial origins.
Gemological Properties
Peridot is a gem-quality form of the mineral olivine, specifically the forsterite variety. Its chemical formula is (Mg, Fe)₂SiO₄, indicating a composition of magnesium, iron, silicon, and oxygen. The green shade of Peridot is determined by its iron composition. It is one of the few gemstones that occurs in only one color, though the shade can vary from yellowish-green to olive to brownish-green.
Here’s a summary of Peridot’s key physical properties:
| Property | Value |
|---|---|
| Mineral | Olivine |
| Color | Lime to olive green |
| Hardness (Mohs) | 6.5-7 |
| Transparency | Transparent to translucent |
| Refractive Index | 1.654-1.690 |
| Crystal System | Orthorhombic |
| Specific Gravity | 3.27-3.37 |
With a hardness of 6.5 to 7 on the Mohs scale, Peridot is relatively durable but requires care to avoid scratches and damage. Its refractive index falls between 1.654 and 1.690, contributing to its characteristic brilliance.
Symbolism and Metaphysical Beliefs
Peridot is imbued with a wealth of symbolism and metaphysical properties. It is associated with growth, prosperity, love, loyalty, and protection. Some believe it brings good luck, peace, and success to those born in August.
Beyond general well-being, Peridot is thought to promote emotional balance, instill feelings of compassion, and even assist in achieving sound sleep. In some traditions, it is believed to instill courage, provide protection and strength of mind, and bring everlasting happiness and stability to marital relations. Ancient Romans and Greeks crafted talismans from Sardonyx (another August birthstone) with images of gods and heroes, believing it aided in eloquence and clarity of thought. While Peridot is the primary August 2nd birthstone, the association with these broader symbolic meanings adds depth to its significance.
Care and Cleaning
Due to its hardness of 6.5-7 on the Mohs scale, Peridot requires careful handling and cleaning. It is susceptible to scratches from harder materials. To clean Peridot jewelry, it is recommended to use warm, soapy water and a soft brush. Avoid harsh chemicals, ultrasonic cleaners, and steam cleaners, as these can damage the stone. After cleaning, rinse thoroughly with clean water and dry with a soft cloth. Storing Peridot jewelry separately from harder gemstones will help prevent scratches and maintain its brilliance.
August Birthstones: A Broader Perspective
While Peridot is the primary birthstone for August, it is important to note that Spinel and Sardonyx are also recognized as August birthstones. Spinel offers a range of colors, including red, pink, and even cobalt blue, while Sardonyx displays striking bands of red and white. These alternative stones expand the options for August-born individuals, each offering unique symbolism and historical significance. Peridot is particularly associated with the Zodiac signs Virgo and Leo, while Sardonyx is linked to Leo. The birth flowers for August are the Gladiolus and Poppy, further enriching the symbolism associated with this month.
Conclusion
