This article explores the geological formation, historical significance, symbolism, and care of peridot, offering a comprehensive understanding of its role as a birthstone.
History and Lore
Peridot has a long and fascinating history that spans across civilizations. Ancient cultures believed in the gemstone’s mystical properties and attributed various meanings to it. The Egyptians referred to peridot as the "gem of the sun," believing it was brought to Earth from an "exploding sun." They mined peridot at night, thinking it absorbed the sun's rays and released them during the evening. Roman scholars, too, recognized its unique qualities, calling it "the evening gem" because it was said to glow in the dark.
In biblical times, peridot was known as chrysolite, a term derived from the Greek word "chrysolithos," meaning golden stone. Historical records suggest that peridot may have been used on the breastplate worn by Aaron, the brother of Moses. This connection to religious artifacts underscores the gemstone's historical significance and its perceived divine properties.
The gemstone's association with protection is also deeply rooted in folklore. It was believed that wearing peridot could protect one from evil spirits and the "terrors of the night." In some traditions, people would string the gemstone on donkey hair and tie it around their left arm for protection. Setting peridot in gold was thought to enhance its powers, and Egyptian priests used goblets encrusted with the gem to connect with their gods.
In Hawaiian tradition, peridot was believed to be the tears of Pele, the goddess of elements. This myth adds a unique cultural dimension to the gemstone, linking it to natural and supernatural forces.
Geological Formation and Sources
Peridot is a variety of the mineral olivine, which forms under extreme conditions deep within the Earth's mantle. It is often found in the hardened lava that carried it to the surface and can also be discovered in meteorites that have traveled from outer space. This dual origin—both terrestrial and extraterrestrial—makes peridot a truly unique gemstone.
The formation of peridot is tied to high-temperature and high-pressure environments. When magma cools, the olivine crystalizes, forming peridot. The gemstone's green color is due to the presence of iron within its chemical structure. The most common sources of peridot include the United States (particularly Arizona and New Mexico), Pakistan, Myanmar, and the Canary Islands.
Peridot's occurrence in meteorites adds to its intrigue. It has been found on the Moon, further emphasizing its connection to space. This extraterrestrial origin gives peridot a distinct allure and makes it one of the few gemstones with a known presence in meteorites.
Gemological Properties
Peridot is a relatively hard gemstone, with a hardness of 6.5 to 7 on the Mohs scale. This makes it suitable for everyday wear, although it requires careful handling to avoid scratches and chips. The gemstone's refractive index ranges from 1.65 to 1.70, contributing to its brilliance and clarity.
One of the most distinctive features of peridot is its color. It ranges from a bright yellow-green to an olive-green hue. This variation in color is due to the presence of different concentrations of iron. Peridot is also known for its pleochroism, meaning it can display different colors when viewed from different angles. This optical property adds to its visual appeal and makes it a popular choice for jewelry.
The chemical composition of peridot is (Mg, Fe)₂SiO₄, indicating that it is a silicate mineral. Its crystal structure is orthorhombic, which affects how it is cut and shaped. Peridot is typically cut into brilliant or mixed cuts to enhance its sparkle and maximize its color.
In terms of clarity, peridot is often included, meaning it may contain visible inclusions. These inclusions are usually small and do not detract from the gemstone's beauty. In fact, some collectors appreciate these natural features as they add character and individuality to each stone.
Symbolism and Metaphysical Beliefs
Peridot has long been associated with positive energy and emotional healing. It is believed to promote compassion, forgiveness, and emotional balance. In many cultures, peridot is considered a stone of renewal and protection. It is said to bring happiness, strength, and prosperity to those who wear it.
The gemstone's connection to the sun and light makes it a symbol of warmth and vitality. It is often used in jewelry and amulets to attract positive energy and ward off negative influences. Peridot is also associated with the heart chakra and is believed to open the heart to love and compassion.
Modern metaphysical beliefs attribute additional properties to peridot. It is said to help reduce stress, encourage forgiveness, and restore emotional balance. Some people use peridot to aid with sleep and to promote a sense of calm and serenity. These properties make peridot a popular choice for those seeking emotional healing and personal growth.
Peridot is also believed to enhance one's sense of purpose and destiny. It is said to help individuals connect with their inner wisdom and gain clarity about their life path. This makes peridot a valuable stone for those seeking guidance and direction.
Care and Cleaning
Given its hardness of 6.5 to 7 on the Mohs scale, peridot is relatively durable but still requires proper care to maintain its beauty. The gemstone should be cleaned with mild soap and warm water. A soft brush, such as a toothbrush, can be used to gently scrub the surface. After cleaning, the gemstone should be rinsed thoroughly and dried with a soft cloth.
Peridot should be stored separately from harder gemstones to prevent scratches. It is best to keep it in a soft pouch or a lined jewelry box. Avoid exposing peridot to extreme temperatures or sudden temperature changes, as this can cause it to crack or fracture.
When wearing peridot jewelry, it is advisable to avoid harsh chemicals and abrasive materials. The gemstone should be removed before engaging in activities that could cause physical damage, such as sports or manual labor. With proper care, peridot jewelry can last for many years, maintaining its brilliance and beauty.
