History and Lore
Peridot has a rich and storied past that spans multiple civilizations. Historically, the gemstone has been used in ancient Egypt, where it was believed to be formed from solidified fire or sunlight. In fact, the name peridot is thought to have originated from the Arabic word "Farida," meaning "unique" or "precious," reflecting its highly valued status. According to historical accounts, peridot was often brought to Europe by returning Crusaders, who presented it to royalty and religious institutions as a symbol of wealth and divine favor.
In medieval Europe, peridot was frequently incorporated into church regalia and religious artifacts. This usage underscores its spiritual importance and the reverence with which it was regarded. Some of these historic pieces remain in museums and ecclesiastical collections today, testifying to the gemstone's long-standing cultural and symbolic role.
The transition of peridot from a sacred gemstone to a widely recognized birthstone occurred in the 20th century. By the early 1900s, peridot had become firmly established as the birthstone for August. This association with the month of August is based on the gemstone's vibrant green color and its availability in a range of shades. The green tones of peridot are often associated with growth, renewal, and vitality—themes that align with the summer season.
In contemporary times, peridot continues to be a popular choice for August birthstone jewelry. It is often used in necklaces, earrings, and rings, where its color and clarity can be showcased to great effect. The gemstone's warm, inviting hue makes it an ideal choice for jewelry that can be worn year-round, regardless of the season.
Geological Formation and Sources
Peridot is a naturally occurring gemstone that forms in the Earth's mantle and is brought to the surface through volcanic activity. It is also found in meteorites, making it one of the few gemstones that can be considered extraterrestrial in origin. The chemical composition of peridot is magnesium iron silicate, and the variation in iron content is what determines its color. The more iron present in the stone, the deeper and more intense the green hue will be.
High-quality peridot is typically found in volcanic regions, where it is mined from basaltic rock. Some of the most notable sources of peridot include:
- Zabargad Island (St. John’s Island), located in the Red Sea, is one of the most historically significant sources of peridot. This island has been a major source of the gemstone for centuries and is still known for producing high-quality stones.
- Arizona, in the United States, is another important source of peridot. The gemstone is often found in volcanic rock formations, and the state is a popular destination for gemstone hunters and collectors.
- Brazil, China, and Madagascar are also known for producing peridot. These countries contribute to the global supply of the gemstone, ensuring that it remains accessible to jewelers and consumers around the world.
The formation of peridot is a slow process that occurs under high heat and pressure. The gemstone is typically found in igneous rock, and its crystalline structure allows it to develop into well-formed, faceted stones. This process results in peridot's characteristic glassy luster and vibrant green color.
Gemological Properties
Peridot is a relatively hard gemstone, with a hardness of 6.5 to 7 on the Mohs scale. This means that it is durable enough to be used in everyday jewelry, such as necklaces and earrings, but it requires some care to avoid scratches and other damage. The gemstone is also known for its strong pleochroism, which means that it can display different colors when viewed from different angles. In some cases, peridot can appear yellowish when viewed from one direction and green from another.
One of the most notable characteristics of peridot is its color. As mentioned earlier, the gemstone ranges in color from a light, almost yellowish green to a deep, rich olive green. The most desirable and valuable peridots are those with a vibrant, intense green color. The presence of iron in the gemstone is responsible for this color variation, and the highest quality peridots are those with a balanced iron content that results in a rich green hue.
In terms of clarity, peridot is generally considered to be a transparent to slightly included gemstone. High-quality peridots are free from visible inclusions and have a clean, glassy appearance. However, some inclusions are natural and can be expected in many peridot stones. These inclusions do not typically affect the gemstone's durability or appearance.
Peridot is also known for its refractive index, which is around 1.65 to 1.69. This refractive index gives the gemstone a bright, sparkling appearance when it is cut and polished. The most common cut for peridot is the brilliant cut, which enhances its refractive properties and allows the gemstone to display its full range of colors and light.
In addition to its physical properties, peridot is also known for its relatively low density. This makes it a lightweight gemstone, which is ideal for use in delicate jewelry designs such as necklaces and earrings. The gemstone's low density also makes it easier to cut and polish, resulting in a high-quality finish that showcases its natural beauty.
Symbolism and Metaphysical Beliefs
Peridot has long been associated with various symbolic and metaphysical beliefs. In ancient times, it was believed to be a protective stone that could ward off evil spirits and negative energy. This belief is reflected in the gemstone's nickname, "the gem of the sun," which suggests its connection to light, energy, and positivity.
In medieval Europe, peridot was considered a symbol of purity and was often used in religious jewelry and regalia. It was also believed to bring good fortune and prosperity to its wearer. These beliefs have persisted into modern times, and peridot is still associated with positive qualities such as happiness, optimism, and strength.
Peridot is also believed to have healing properties, particularly in relation to emotional well-being. It is thought to help calm the mind, reduce stress, and promote a sense of inner peace. Some people believe that peridot can help with anxiety and depression by encouraging a sense of calm and tranquility.
In addition to its emotional benefits, peridot is also believed to have physical healing properties. It is thought to help with digestive issues, skin conditions, and even insomnia. While these beliefs are not supported by scientific evidence, they remain popular among those who use peridot for its metaphysical properties.
The gemstone's association with the sun and light is also reflected in its use in jewelry. Peridot is often used in summer-themed jewelry designs, where its vibrant green color complements the warm tones of the season. This connection to the sun and light is also reflected in the gemstone's name, which is derived from the Arabic word for "unique."
Care and Cleaning
As with all gemstones, peridot requires proper care and maintenance to ensure its longevity and beauty. The gemstone's hardness of 6.5 to 7 on the Mohs scale means that it is relatively durable, but it can still be scratched or damaged if not handled with care. To maintain the beauty of peridot jewelry, it is important to follow a few simple care tips.
First, it is advisable to avoid using abrasive chemicals or ultrasonic cleaners when cleaning peridot jewelry. These types of cleaners can scratch the surface of the gemstone and reduce its luster. Instead, it is recommended to use a soft cloth moistened with water to gently wipe the gemstone and remove any dirt or debris.
It is also important to store peridot jewelry in a safe place to prevent scratches and damage. A jewelry box or a small pouch is ideal for storing peridot pieces, as it will protect them from contact with other gemstones and metals that could cause scratches.
In terms of wearing, peridot is a gemstone that can be worn on a daily basis. However, it is important to avoid exposing it to harsh conditions, such as extreme heat or cold, which can affect the gemstone's clarity and color. It is also advisable to remove peridot jewelry before engaging in activities that could cause it to be knocked or dropped.
Regular maintenance, such as cleaning and storing, will help to keep peridot jewelry looking its best for many years. With proper care, peridot can remain a beautiful and meaningful piece of jewelry that can be cherished for generations.
