History and Lore
Peridot has a long and storied history, with records of its use dating back to ancient times. The gemstone is believed to have been used as early as 1500 BCE in Ancient Egypt, where it was known as “the gem of the sun” and was closely associated with the sun god Ra. Egyptian priests were said to wear peridot to harness its protective powers and to ensure safe passage through the underworld.
In addition to its Egyptian roots, peridot was also highly valued in the Middle East and the Mediterranean. It was a popular gemstone among the Romans, who used it in jewelry and as a decorative element in their architecture. Peridot was also found in the tombs of Egyptian pharaohs and was often used as inlay in furniture and religious artifacts.
One of the most intriguing legends associated with peridot is the Hawaiian belief that the gemstone was formed from the tears of Pele, the goddess of volcanoes. According to Hawaiian lore, Pele cried when she was separated from her lover, and her tears turned into peridot. This story reflects the gemstone’s connection to fire and the sun, as well as its association with emotion and passion.
In medieval Europe, peridot was often used in religious and ceremonial settings. It was believed to have protective powers and was worn by knights and warriors to guard against evil spirits and to enhance their courage. Some sources suggest that peridot was also used as a substitute for emeralds, especially in times when emeralds were scarce or too expensive to obtain.
The gemstone’s modern status as a birthstone was officially recognized in the United States in 1912, when the National Association of Jewelers updated the traditional birthstone list. Peridot replaced sardonyx as the birthstone for August, reflecting a shift toward more transparent and colorful gemstones that were more suitable for modern jewelry designs.
Geological Formation and Sources
Peridot is a gem-quality variety of the mineral olivine, a magnesium iron silicate that forms in the Earth’s mantle and is brought to the surface through volcanic activity. The gemstone is typically found in igneous rocks, such as basalt and peridotite, as well as in meteorites. This unique formation process gives peridot its distinct chemical composition and physical properties.
The color of peridot is directly related to its iron content. The more iron present in the stone, the deeper the green hue. High-quality peridot is characterized by its vivid green color, which can range from light yellow-green to deep, rich green. Unlike emeralds, which can have a bluish or greenish cast, peridot has a distinct yellowish overtone that sets it apart.
Peridot is found in several parts of the world, including the United States, Egypt, China, Brazil, and Australia. The United States is one of the largest producers of peridot, with significant deposits in Arizona, which is home to one of the largest peridot mines in the world. The gemstone is also mined in the Red Sea region of Egypt, where it has been historically significant.
The availability of peridot varies depending on the size and quality of the stone. While smaller stones are relatively common, larger, high-quality peridot is rarer and more valuable. The scarcity of large, pure green peridot makes it a sought-after gemstone among collectors and jewelers.
Gemological Properties
Peridot is a unique gemstone with distinct physical and optical properties. As a member of the olivine mineral group, it has a glassy luster and a relatively high refractive index, which contributes to its brilliance and fire. The gemstone has a Mohs hardness of 6.5 to 7, which makes it durable enough for everyday wear but not as hard as diamonds or sapphires.
One of the most notable characteristics of peridot is its high double refraction. This means that light passing through the stone is split into two rays, creating a visible doubling of features when viewed through the table. This effect is more pronounced in certain cuts and can affect the appearance of the stone, particularly in faceted designs.
Peridot is also known for its pleochroism, a phenomenon in which the gemstone appears to have different colors when viewed from different angles. In peridot, this is typically a subtle effect, with the stone appearing slightly different in hue depending on the direction of the light.
The chemical formula for peridot is (Mg, Fe)₂SiO₄, reflecting its composition as a magnesium iron silicate. This composition gives peridot its unique properties and makes it one of the few gemstones that can be found in meteorites. In fact, some of the finest peridot has been found in meteorites, where it forms under extreme conditions.
Peridot is typically cut in a variety of styles, including brilliant cuts, emerald cuts, and mixed cuts. The choice of cut depends on the size and quality of the stone, as well as the desired aesthetic. Larger peridot stones are often cut in step or mixed cuts to maximize their brilliance and fire, while smaller stones may be cut in brilliant cuts to enhance their sparkle.
Symbolism and Metaphysical Beliefs
Peridot has long been associated with positive energy, protection, and emotional healing. In ancient times, it was believed to have the power to ward off nightmares and negative thoughts, making it a popular stone for use in sleep-related rituals. The gemstone was also associated with the sun and was believed to bring warmth, light, and vitality to those who wore it.
In addition to its protective qualities, peridot was also thought to promote emotional balance and inner peace. It was believed to help individuals overcome anger, jealousy, and resentment, making it a valuable stone for those seeking emotional healing. In some traditions, peridot was also used as a symbol of friendship and was given as a gift to strengthen bonds between people.
Modern metaphysical practitioners continue to use peridot for its calming and energizing properties. The gemstone is often used in meditation and energy healing to promote a sense of well-being and to encourage positive thinking. It is also believed to stimulate creativity and to help individuals overcome fear and insecurity.
In addition to its emotional and spiritual properties, peridot is also associated with physical health. It is believed to support the digestive system, improve metabolism, and aid in the treatment of certain ailments. While these claims are not scientifically proven, many people continue to use peridot as a complementary therapy in conjunction with traditional medical treatments.
Care and Cleaning
Due to its relatively high hardness, peridot is a durable gemstone that can withstand everyday wear. However, it is important to take proper care of peridot to maintain its beauty and longevity. The gemstone is sensitive to heat and should not be exposed to high temperatures, as this can cause it to lose its color or become brittle.
Peridot should be cleaned regularly to remove dirt and oils that can dull its luster. The best way to clean peridot is with a soft brush and warm, soapy water. A mild detergent such as dish soap can be used to gently clean the stone, followed by a rinse with lukewarm water. It is important to avoid using harsh chemicals or abrasive cleaners, as these can damage the surface of the gemstone.
After cleaning, peridot should be dried with a soft cloth to prevent water spots. It is also a good idea to store peridot separately from other gemstones to prevent scratches and abrasions. A soft pouch or a lined jewelry box is ideal for storing peridot.
When wearing peridot jewelry, it is important to avoid exposing the gemstone to harsh environments. Peridot should not be worn during activities that involve heavy impact or exposure to chemicals, as this can cause damage or discoloration. With proper care, peridot can maintain its beauty for a lifetime and can be passed down as a cherished family heirloom.
