For those born on August 7, the birthstone is peridot, a gemstone celebrated for its vibrant green hue and rich historical legacy. Known for its associations with friendship, prosperity, and serenity, peridot is not only a symbol of the month of August but also a gemstone with deep cultural, geological, and metaphysical significance. This article delves into the multifaceted nature of peridot, exploring its geological origins, historical use, gemological properties, symbolic meanings, and practical care tips. As we uncover the story behind this remarkable gemstone, we gain a deeper appreciation of its enduring charm and value.
A Gemstone of Many Facets
Peridot is a gem-quality variety of the mineral olivine, a magnesium-iron silicate that forms in volcanic environments. Its color ranges from a pale, almost yellowish green to a more intense olive green, with the most desirable specimens exhibiting a pure, lime-green hue. Peridot is unique among gemstones in that it only occurs in one color—green—making it a standout in the world of precious stones. The gemstone is often referred to as the “gem of the sun,” a title given to it by the ancient Egyptians, who believed it to be a gift from the sun god. This sun-like brilliance is further enhanced by peridot’s glassy luster and its ability to emit a subtle glow under artificial light, earning it the nickname “evening emerald.”
While peridot is the primary birthstone for those born on August 7, it is also one of three birthstones associated with the entire month of August, the others being spinel and sardonyx. This unique distinction reflects the gemstone's historical significance and its enduring popularity in jewelry and spiritual practices.
History and Lore of Peridot
Peridot has a rich and storied history that spans thousands of years, with evidence of its use dating back to ancient civilizations. One of the earliest recorded sources of peridot is the Red Sea island of Zabargad, which means “olivine” in Arabic. This island, known for its harsh and unforgiving environment, has been a primary source of high-quality peridot for centuries. The gemstone was mined from the island’s rocky fissures, where it formed in volcanic lava flows. The beaches of Zabargad are often tinged with a greenish hue due to the presence of tiny peridot crystals, a testament to the gem’s natural abundance in this location.
In ancient Egypt, peridot was highly valued and believed to possess protective and healing properties. It was used in jewelry, amulets, and religious artifacts, with the belief that it could ward off nightmares and negative energies. The Egyptians also associated peridot with the sun, believing that it was formed from the tears of Ra, the sun god. This reverence for the gemstone is reflected in its common name, “gem of the sun,” which continues to resonate in modern times.
Peridot’s historical significance is not limited to Egypt. It was also a prized gem in ancient Rome, where it was often used in rings and pendants. During the Middle Ages, peridot was a popular gemstone in Europe, particularly in Germany, where it was featured in religious artifacts such as the Shrine of the Three Holy Kings in Cologne Cathedral. This shrine, which contains 200 carats of peridot, was once mistaken for emeralds, highlighting the gemstone’s similarity in appearance to other precious stones.
In more recent history, peridot has been found in unexpected places, such as meteorites and volcanic rocks. Some of the finest peridot specimens have been discovered in meteorites that have fallen to Earth, adding a cosmic dimension to its allure. Additionally, peridot has been mined in various locations around the world, including the United States, where the San Carlos Indian Reservation in Arizona is a notable source of the gemstone.
Geological Formation and Sources
Peridot is formed through geological processes that involve the cooling and solidification of magma, a molten rock found beneath the Earth’s surface. As magma cools, minerals such as olivine begin to crystallize, forming the gemstone. Peridot is typically found in volcanic environments, where it can be extracted from basaltic rocks. The gemstone is also found in meteorites, where it forms under the extreme conditions of space.
The most notable sources of peridot include Zabargad, an island in the Red Sea that has been a primary source of the gemstone for centuries. Other significant sources include Brazil, China, Kenya, Sri Lanka, Australia, Mexico, and the Mogok district of Myanmar (Burma). The San Carlos Indian Reservation in Arizona, USA, is also known for producing high-quality peridot, particularly in small stones.
Peridot’s formation in volcanic and meteoritic environments gives it a unique geological origin that sets it apart from other gemstones. This cosmic connection adds to its allure, making it a fascinating subject for gemologists and collectors alike.
Gemological Properties of Peridot
Peridot is a versatile gemstone with a range of gemological properties that make it suitable for various types of jewelry. It has a hardness of 6.5 to 7 on the Mohs scale, which means it is relatively durable but still requires careful handling to avoid scratches and damage. The gemstone is composed of magnesium-iron silicates, and its color is determined by the amount of iron present in the crystal structure. The higher the iron content, the more brownish the hue of the peridot.
Peridot is known for its glassy luster and its ability to refract light, which gives it a brilliant and vibrant appearance. The gemstone is typically transparent to translucent, with a refractive index ranging from 1.65 to 1.70. These properties make peridot an excellent choice for jewelry, particularly for pieces that require durability and brilliance.
One of the most distinctive features of peridot is its color. Unlike other gemstones that can occur in a variety of colors, peridot is only found in green, making it unique in the world of precious stones. The most desirable peridot specimens exhibit a pure, lime-green color, while others may have a more yellowish or brownish tint. The gemstone’s color can also change under different lighting conditions, appearing greener under artificial light and more yellowish under natural daylight.
Symbolism and Metaphysical Beliefs
Peridot is associated with a range of symbolic meanings and metaphysical properties that have been attributed to it across different cultures and eras. In ancient Egypt, peridot was believed to have protective and healing properties. It was used in amulets and charms to ward off nightmares and negative energies. The gemstone was also associated with the sun, and it was believed that wearing peridot could bring warmth and vitality to the wearer.
In modern times, peridot is often associated with friendship, prosperity, and serenity. It is believed to promote inner peace and emotional stability, making it a popular choice for those seeking balance and harmony in their lives. Peridot is also associated with vitality and energy, and it is believed to boost one’s energy levels and life force. These properties make it a meaningful gemstone for those born on August 7, as well as for anyone who wishes to embrace its positive qualities.
Peridot is also believed to have cleansing properties, both physically and spiritually. It is said to purify the body and the mind, helping to remove negative thoughts and emotions. This makes it a popular choice for meditation and spiritual practices. Peridot is also believed to attract abundance and financial success, making it a valuable gemstone for those seeking prosperity and wealth.
Care and Cleaning of Peridot
Peridot is a relatively easy gemstone to care for, but it does require some special considerations due to its gemological properties. One of the most important things to remember is that peridot has a hardness of 6.5 to 7 on the Mohs scale, which means it can scratch easily if not handled with care. It is also sensitive to high temperatures and rapid changes in temperature, which can cause it to lose its shine or become discolored.
To clean peridot, it is recommended to use a mild soap, such as dishwashing detergent, and a soft toothbrush. Soak the gemstone in a bowl of warm water with a small amount of detergent, then gently scrub it with the toothbrush. Rinse the peridot in warm, clean water and dry it with a soft cloth. It is best to allow the gemstone to air dry rather than using a heat source, as this can cause damage.
Peridot should not be cleaned using ultrasonic or steam cleaners, as these can cause damage to the gemstone. It is also important to avoid using household cleaners that contain hydrochloric or sulfuric acid, as these can cause the gemstone to lose its shine. If you wear peridot jewelry daily, it is recommended to apply makeup and perfumes before wearing the jewelry, as the chemicals in these products can compromise the color of the gemstone.
When storing peridot jewelry, it is best to keep it separate from other gemstones to avoid scratches. A dedicated jewelry box or a simple plastic organizer box with foam-filled jars or jewelry bags can help protect the gemstone from damage. It is also recommended to store peridot in acid-free paper envelopes to prevent any chemical reactions that could affect its appearance.
