History and Lore
Peridot has a long and storied history, with references to the gemstone dating back over 4,000 years. The ancient Egyptians were among the first known civilizations to value peridot. They mined the gemstone on the Red Sea island of Zabargad, which remained the primary source for the gemstone until the 20th century. The Egyptians called peridot the “gem of the sun,” believing it had protective powers against the terrors of the night. This belief was particularly strong during the Pharaonic era, where peridot was often used in religious and ceremonial contexts.
The name "peridot" is believed to come from the Arabic word "faridat," meaning gem. Throughout history, peridot has been confused with other green gemstones, including emerald and topaz. In fact, many "emeralds" in medieval European cathedral treasures have later been identified as peridots. This misidentification is partly due to the gemstone’s similar color and the limited knowledge of mineralogy at the time.
Peridot was also highly valued in ancient Rome, where it was used in jewelry and amulets. The gemstone was believed to bring good fortune and was often worn by soldiers for protection in battle. In the Middle Ages, peridot was associated with healing and was used in various medicinal practices. Some medieval texts mention peridot being used to treat ailments and to ward off evil spirits.
In more recent history, peridot has gained renewed popularity, especially in the 20th and 21st centuries. The gemstone is now widely recognized as the modern birthstone for August 5th, and its use in jewelry has expanded to include a wide range of designs, from classic to contemporary.
Geological Formation and Sources
Peridot is a gem-quality variety of the mineral olivine, which is a magnesium iron silicate. The gemstone's distinctive green color is primarily due to the presence of iron in its chemical composition. The name "olivine" comes from the Latin word for olive, "oliva," due to the gemstone’s characteristic green color, which can range from yellowish-green to a vibrant lime hue.
Peridot forms deep within the Earth's mantle, where it is brought to the surface through volcanic activity or meteorite impacts. The gemstone is also found in meteorites, particularly in certain types of stony meteorites, making it one of the few gemstones that can be extraterrestrial in origin.
The primary sources of peridot today include the United States, China, and Myanmar. In the United States, peridot is found in Arizona, particularly in the area around the San Carlos Apache Reservation. These deposits are known for producing high-quality peridot with a rich green color. China is another significant source, with peridot being mined in the provinces of Xinjiang and Yunnan. The gemstone from these regions is often noted for its clarity and vibrant color.
Myanmar, previously known as Burma, has also been a source of peridot. However, the country's political and economic situation has affected the gemstone trade in recent years. As a result, the supply of peridot from Myanmar has decreased, and other countries have become more prominent in the global market.
Peridot is also found in other parts of the world, including Brazil, Egypt, and the Democratic Republic of the Congo. Each of these regions produces peridot with slightly different characteristics, such as variations in color intensity and clarity. The availability of peridot from these sources has helped to make the gemstone more accessible to jewelers and consumers worldwide.
Gemological Properties
Peridot is a unique gemstone with distinct gemological properties that make it stand out in the world of colored gemstones. One of the most notable characteristics of peridot is its color, which ranges from yellowish-green to a vibrant lime hue. This color variation is primarily due to the iron content in the gemstone. The higher the iron content, the deeper and more intense the green color will be.
In terms of hardness, peridot has a relatively low rating on the Mohs scale of mineral hardness, with a rating of 6.5 to 7. This means that peridot is not as hard as gemstones such as ruby or sapphire, which have a hardness of 9, or even topaz, which has a hardness of 8. However, peridot is still a durable gemstone that can be worn in everyday jewelry if properly cared for. Its low hardness makes it more susceptible to scratches and chips, so it is advisable to store peridot in a soft cloth or a separate compartment to prevent damage.
Peridot has a refractive index of 1.65 to 1.69, which is relatively high compared to other gemstones. This means that peridot can refract light effectively, giving it a brilliant and sparkling appearance. The gemstone also has a birefringence of 0.036 to 0.038, which can cause a double image effect when viewed through the stone. This effect is more noticeable in certain types of peridot and can add to the gemstone's unique visual appeal.
In terms of clarity, peridot is typically found with inclusions, which are small internal features that can affect the gemstone's transparency. These inclusions are often visible to the naked eye and can vary in size and shape. Some inclusions are considered desirable by gemologists and collectors, as they can add character to the gemstone. However, peridot with fewer inclusions is generally more valuable and sought after in the jewelry market.
Peridot is also known for its pleochroism, which is the ability to display different colors when viewed from different angles. In some cases, peridot can appear yellowish-green when viewed from one angle and a more intense green when viewed from another. This property can make peridot a fascinating gemstone to examine under different lighting conditions.
The carat weight of peridot is another important factor in its value and desirability. While peridot is available in a wide range of sizes, the most valuable stones are typically those that are large and of high quality. Peridot is relatively abundant compared to other gemstones, which means that it is often more affordable than stones such as diamonds or emeralds.
Symbolism and Metaphysical Beliefs
Peridot has long been associated with various symbolic and metaphysical beliefs across different cultures and time periods. One of the most well-known symbols of peridot is its connection to the sun. In ancient Egypt, peridot was referred to as the "gem of the sun," and it was believed to have protective powers against the terrors of the night. This belief was particularly strong during the Pharaonic era, where peridot was often used in religious and ceremonial contexts.
In addition to its protective properties, peridot has been associated with good fortune and prosperity. The gemstone is believed to bring positive energy and success to those who wear it. This symbolism has made peridot a popular choice for jewelry in cultures that value good luck and abundance. The gemstone is also associated with healing and is believed to have various therapeutic properties. Some cultures have used peridot in the treatment of ailments and as a protective amulet against evil spirits.
Peridot is also believed to have a calming effect on the mind and body. It is often used in meditation and crystal healing practices to promote relaxation and emotional balance. The gemstone is said to help release negative emotions and promote a sense of inner peace. This property makes peridot a popular choice for those seeking emotional healing and mental clarity.
In modern times, peridot continues to be valued for its symbolic and metaphysical properties. As the August birthstone, it is believed to bring good luck, peace, and success to those born in this month. Peridot is also associated with the zodiac sign Leo, which is known for its fiery and passionate nature. The gemstone is believed to complement the natural abilities of Leos and bring a sense of calm and focus to their lives.
Peridot is also used in various spiritual practices and is believed to have a connection to the heart chakra. This connection is thought to help promote love, compassion, and emotional healing. The gemstone is often used in rituals and ceremonies to enhance these qualities and to encourage positive change.
Despite its long history of symbolic and metaphysical beliefs, it is important to note that these properties are not scientifically proven. The beliefs surrounding peridot are based on cultural traditions and personal experiences, and their validity may vary from person to person. However, the gemstone's rich history and cultural significance continue to make it a popular and meaningful choice for those who value its symbolic properties.
Care and Cleaning
Due to its relatively low hardness on the Mohs scale, peridot requires special care to maintain its beauty and longevity. While it is a durable gemstone, it can be more susceptible to scratches and chips compared to harder gemstones such as diamonds or rubies. Proper care and cleaning can help preserve the gemstone's appearance and extend its lifespan.
One of the most important aspects of peridot care is storing the gemstone in a safe and secure place when it is not being worn. Peridot should be stored in a soft cloth or a separate compartment to prevent it from coming into contact with harder gemstones that may cause scratches. It is also advisable to store peridot in a cool, dark place to protect it from exposure to direct sunlight, which can cause the gemstone to fade over time.
Cleaning peridot should be done with caution to avoid damaging the gemstone. The best way to clean peridot is by using a soft cloth and a mild soap solution. The gemstone should be gently wiped with the cloth to remove any dirt or debris. It is important to avoid using harsh chemicals or abrasive cleaners, as these can damage the gemstone's surface and affect its appearance.
Peridot can also be cleaned using a soft-bristled brush and warm water. The brush should be used gently to avoid scratching the gemstone. After cleaning, the gemstone should be rinsed with clean water and dried with a soft cloth to prevent water spots.
When wearing peridot jewelry, it is important to be mindful of the gemstone's low hardness. Peridot should not be worn during activities that involve rough handling or exposure to harsh chemicals. For example, peridot should not be worn while swimming, gardening, or using household cleaning products, as these activities can damage the gemstone.
In addition to proper care and cleaning, it is important to have peridot jewelry inspected by a professional jeweler on a regular basis. A jeweler can check for any signs of wear or damage and make any necessary repairs to ensure the gemstone remains in good condition.
By following these care and cleaning guidelines, peridot can be enjoyed for many years. Its vibrant green color and unique properties make it a valuable and meaningful gemstone that can be passed down through generations.
