The August 28th birthstone, peridot, is a gemstone that has captivated humanity for centuries with its radiant green hues and its deep historical and symbolic significance. Known as the “Gem of the Sun” by the ancient Egyptians, peridot has been cherished across cultures and eras for its beauty and metaphysical properties. This article delves into the geological and historical background of peridot, its gemological properties, and its symbolic and spiritual associations. As a birthstone for those born on August 28th, peridot offers a unique blend of aesthetic appeal and meaningful symbolism.
History and Lore
Peridot has a rich and storied history that dates back to ancient civilizations. The gemstone was particularly revered by the ancient Egyptians, who believed that peridot was formed by solidified rays of the sun. They referred to it as the “Gem of the Sun” and often used it in their jewelry and religious artifacts. In fact, peridot was so highly valued that it was once mined from the volcanic island of St. John’s, located off the coast of Egypt.
The gemstone also has a fascinating connection to meteorites. Peridot is one of the few gemstones that can be found in extraterrestrial sources, as it occurs naturally in meteorites. This unique origin has contributed to the gemstone's association with cosmic and celestial energies, further enhancing its allure and mystique.
In medieval Europe, peridot was believed to possess protective qualities. It was thought to ward off nightmares and evil spirits, making it a popular choice for amulets and talismans. This belief in the gemstone's protective powers continued into the Renaissance period, where peridot was often used in jewelry to symbolize purity and renewal.
The gemstone’s journey to becoming a modern birthstone began in the 20th century. Peridot was officially recognized as the birthstone for August in the 1910s by the American National Association of Jewelers. This designation was later reinforced in the 1950s by the Jewelers of America, which included peridot as one of the primary birthstones for the month of August. Today, peridot is celebrated not only for its historical significance but also for its vibrant color and versatility in jewelry design.
Geological Formation and Sources
Peridot is a variety of the mineral olivine, which is a magnesium iron silicate. The gemstone is formed in the Earth's mantle and is brought to the surface through volcanic activity. This process results in the creation of peridot in various geological settings, including volcanic rocks and meteorites. The presence of iron in its composition is what gives peridot its characteristic green color, which can range from a pale yellow-green to a deep olive green.
The gemstone is primarily found in specific regions around the world. Notable sources of peridot include China, Myanmar, Vietnam, Pakistan, Tanzania, the United States, and Sardinia (Italy). Each of these locations contributes to the global supply of peridot, with the quality and color of the gemstone varying depending on the geological conditions of the area.
In addition to natural sources, peridot can also be synthesized in laboratories. This process allows for the ethical and sustainable production of peridot, making it accessible to a wider audience. Lab-grown peridot is chemically identical to its natural counterpart and is often used in jewelry to provide an affordable alternative to naturally occurring peridot.
Gemological Properties
Peridot is a gemstone that is characterized by its unique physical and optical properties. One of the most notable aspects of peridot is its color, which is solely green due to the presence of iron in its chemical composition. This makes peridot one of the few gemstones that occur in only one color, distinguishing it from other gemstones that can be found in multiple hues.
The gemstone has a hardness of 6.5 to 7 on the Mohs scale, which makes it relatively durable but still susceptible to scratches and chips. Due to its moderate hardness, peridot is best suited for jewelry that is not subjected to constant wear, such as pendants and earrings. However, with proper care, peridot can also be used in rings and bracelets.
Peridot has a chemical formula of (Mg,Fe)₂SiO₄, which indicates that it is a silicate mineral containing magnesium and iron. The gemstone has a refractive index of 1.65 to 1.70, which contributes to its brilliance and luster. Peridot is also known for its pleochroism, a property that allows it to display different colors when viewed from different angles. This phenomenon adds to the gemstone's visual appeal and makes it a popular choice for jewelry designers.
In terms of clarity, peridot is typically found in transparent to translucent forms, with inclusions that are often visible to the naked eye. These inclusions can range from small, needle-like structures to larger, more pronounced features. While inclusions are common in peridot, they do not significantly affect the gemstone's beauty or value. In fact, some collectors appreciate the presence of inclusions as they add character and uniqueness to each piece.
Symbolism and Metaphysical Beliefs
Peridot has long been associated with various symbolic and metaphysical properties. In ancient times, it was believed to possess protective qualities that could ward off nightmares and evil spirits. This belief was particularly prevalent in medieval Europe, where peridot was used in amulets and talismans to provide protection and promote good health.
The gemstone is also associated with the Sun, reflecting its luminous and energetic qualities. This connection to the Sun has contributed to peridot's symbolic association with warmth, vitality, and positivity. In many cultures, peridot is believed to bring about a sense of renewal and growth, making it a popular choice for those seeking to embrace change and new beginnings.
In addition to its protective and renewing properties, peridot is also believed to promote prosperity and personal growth. This makes it a popular choice for those seeking to enhance their career or financial opportunities. The gemstone is often used in meditation and spiritual practices to help individuals connect with their inner selves and achieve a greater sense of balance and harmony.
Modern metaphysical beliefs also associate peridot with emotional healing and self-acceptance. It is believed to help individuals overcome negative emotions and foster a sense of inner peace. This makes peridot a popular choice for those seeking to improve their emotional well-being and cultivate a more positive outlook on life.
Care and Cleaning
Due to its moderate hardness on the Mohs scale, peridot requires careful handling and cleaning to maintain its beauty and durability. The gemstone is susceptible to scratches and chips, so it is important to store peridot jewelry in a soft cloth or a padded jewelry box to prevent damage. It is also advisable to avoid exposing peridot to harsh chemicals, as this can dull its luster and potentially damage the stone.
When it comes to cleaning peridot, a mild soap and warm water solution is recommended. The gemstone can be gently cleaned with a soft cloth or a soft-bristled brush to remove any dirt or debris. It is important to avoid using ultrasonic cleaners or steam cleaners, as these can cause damage to the gemstone, particularly if it contains inclusions or is of lower quality.
Peridot should also be protected from extreme temperatures and sudden temperature changes, as this can cause the gemstone to crack or break. It is advisable to remove peridot jewelry before engaging in activities that involve exposure to high temperatures or direct sunlight, as prolonged exposure can potentially affect the gemstone's color and clarity.
In addition to regular cleaning and proper storage, it is important to periodically have peridot jewelry inspected by a professional jeweler. This can help identify any signs of wear or damage and ensure that the gemstone remains in optimal condition. By following these care and cleaning guidelines, peridot can be enjoyed for many years and passed down as a cherished heirloom.
