For those born on August 21st, the birthstone is the vibrant and historically rich gemstone known as Peridot. This gemstone is celebrated not only for its unique color but also for its deep symbolic and scientific significance. Peridot’s striking green hue, derived from its iron content, makes it a standout among other gemstones. This article explores the various facets of Peridot, from its geological formation and historical use to its symbolic meaning and care instructions. Whether you are a gemstone enthusiast, a jewelry buyer, or a student of gemology, this guide offers a detailed and insightful look into the world of Peridot.
History and Lore
Peridot has a rich and storied history that spans thousands of years. Ancient civilizations revered it for its beauty and protective qualities. The gemstone's name may derive from the Arabic word "faridat," meaning gem. This connection highlights the deep cultural significance that Peridot has held across different regions and eras.
In ancient Egypt, Peridot was known as the "gem of the sun" and was believed to protect against evil spirits, especially when set in gold. The Egyptians mined Peridot from an island in the Red Sea known today as St. John’s Island (or Zabargad). The gemstone's bright green color symbolized life and renewal, making it a valuable asset for spiritual rituals. Medieval churches often adorned their treasuries with Peridot jewels, believing they held special protective powers. This historical reverence underscores the gemstone's enduring appeal and its role as a symbol of positive energy and protection.
Throughout history, Peridot has often been confused with other gems such as topaz and emerald. The Red Sea island of Topazios, a source of the name "topaz," actually produced Peridot. This misidentification has led to some fascinating historical anecdotes. For example, the Shrine of the Three Holy Kings in Germany’s Cologne Cathedral is decorated with 200 carats of gems that were believed to be emeralds but are, in fact, Peridot. Some historians even speculate that Cleopatra’s famous emerald collection may have been comprised of Peridot. These historical errors highlight the gemstone’s unique properties and the challenges of early gemology.
Geological Formation and Sources
Peridot is a variety of the mineral olivine, a silicate mineral that forms under extreme heat and pressure in the Earth’s mantle. This formation process is unique, as it occurs deep within the Earth, unlike most other gemstones that form in the Earth's crust. The presence of iron in Peridot’s chemical structure is responsible for its characteristic green color. The more iron a Peridot contains, the deeper its green tone. This relationship between iron content and color intensity is a key factor in determining the value and desirability of Peridot specimens.
The gemstone can also be found in meteorites that traveled from outer space. This extraterrestrial origin adds another layer of intrigue to Peridot's geological story. The only other gemstone that forms at such depths is diamonds, emphasizing Peridot’s rare and unique formation process.
Peridot is primarily sourced from volcanic lava flows and meteorite fragments. The Luc Yen region in northern Vietnam has produced this August birthstone in deep red, purple, pink, violet, and violet-blue since the 1980s. The vivid blue spinels found in this region in the 2000s have captivated gem collectors. Similarly, a 2007 discovery in Tanzania of pinkish and orangy red spinel has added to the allure of Peridot. These sources highlight the diverse and sometimes unexpected locations where Peridot can be found.
The process of mining Peridot involves navigating challenging terrains. In Vietnam, getting to the mines requires a five- to six-hour drive from Hanoi and then hiking or biking for several more hours. This effort underscores the gemstone's value and the dedication required to extract it from its natural environment.
Gemological Properties
Peridot is a unique gemstone with distinct gemological properties. It is a variety of the mineral olivine, which is rich in iron and magnesium. The presence of iron is what gives Peridot its characteristic green color. Unlike many other gemstones, Peridot does not occur in a wide range of colors—its green hue is the only one found in nature. This unique characteristic sets Peridot apart from other August birthstones such as Spinel and Sardonyx, which can appear in a broader spectrum of colors.
The color of Peridot can vary from a pale yellow-green to a deep, rich green, depending on the concentration of iron in its chemical composition. This variation in color intensity is a key factor in determining the value and desirability of Peridot specimens. The more iron a Peridot contains, the deeper its green tone. This relationship between iron content and color intensity is a key factor in determining the value and desirability of Peridot specimens.
Peridot has a hardness of 6.5 to 7 on the Mohs scale, making it relatively durable but not as hard as diamonds or sapphires. This hardness level means that Peridot is suitable for use in jewelry but requires careful handling to avoid scratches and damage. The gemstone does not exhibit cleavage, which is the tendency to split along specific planes when struck. This lack of cleavage makes Peridot less prone to fracturing, but it can still be damaged if exposed to high heat or harsh chemicals.
Peridot is a transparent to translucent gemstone with a vitreous luster. It is a single refractive gemstone, meaning it does not have double refraction, which is the splitting of light into two rays as it passes through a gemstone. This property contributes to Peridot’s clarity and brilliance when cut and polished. The gemstone is also known for its pleochroism, the ability to display different colors when viewed from different angles. However, this effect is minimal in Peridot and is not as pronounced as in other gemstones such as tourmaline or sapphire.
Symbolism and Metaphysical Beliefs
Peridot has long been associated with positive energy, compassion, and renewal. Known as the “stone of compassion,” Peridot is believed to promote kindness, emotional balance, and unconditional love. Its vibrant green color is often linked to the heart chakra, which represents love, healing, and emotional balance. This connection makes Peridot a popular choice for those seeking to enhance their emotional well-being and foster positive relationships.
The gemstone's symbolic significance extends beyond its color and chakra associations. Peridot is believed to dispel negative emotions such as jealousy and resentment while promoting confidence, joy, and abundance. This association with positivity and renewal is reflective of the gemstone’s natural color, which embodies the lush and rejuvenating aspects of nature. These properties make Peridot a valuable gemstone for those seeking to harmonize their emotions and promote well-being.
In ancient times, Peridot was also believed to have protective qualities. The Egyptians used it in jewelry and seals to protect against evil spirits. This belief in Peridot’s protective powers has persisted through the centuries, with many cultures attributing similar properties to the gemstone. In medieval times, Peridot was often used in religious jewelry and seals, believed to hold special protective powers.
Peridot is also associated with growth and prosperity. The gemstone’s connection to the heart chakra and its vibrant green color make it a symbol of new beginnings and the flourishing of life. This symbolism is particularly relevant for those born in August, as the gemstone is believed to bring good fortune and success to its wearer.
Care and Cleaning
Proper care and cleaning are essential to maintaining the beauty and longevity of Peridot. Given its hardness of 6.5 to 7 on the Mohs scale, Peridot is relatively durable but still requires careful handling. The gemstone is stable when exposed to light and chemicals, but high heat can cause some colors of Peridot to fade. Therefore, it is advisable to avoid exposing Peridot to extreme temperatures.
Cleaning Peridot can be done using warm soapy water, which is always a safe alternative. Ultrasonic and steam cleaners can also be used, but the presence of fractures could pose a problem. If the gemstone has any cracks or fractures, it is best to avoid using these cleaning methods to prevent further damage.
When storing Peridot jewelry, it is recommended to keep it in a soft cloth or a jewelry box to prevent scratches from other gemstones. It is also important to avoid exposing Peridot to harsh chemicals, as these can dull its luster and potentially damage the gemstone. Regular inspection of Peridot jewelry is advisable to ensure that the setting is secure and that the gemstone is not loose or damaged.
For those who wear Peridot regularly, it is important to be mindful of activities that may subject the gemstone to impact or pressure. While Peridot is relatively durable, it is not as hard as diamonds or sapphires, so it is advisable to remove Peridot jewelry during activities that may cause it to chip or crack. By following these care and cleaning guidelines, the beauty and value of Peridot can be preserved for years to come.
