History and Lore: The Gem of the Sun
Peridot's history is as vibrant as its color. The gemstone has been treasured since ancient times, with one of its most significant historical associations originating in Egypt. Known to the Egyptians as “the gem of the sun,” peridot was believed to possess protective powers. Ancient lore held that the stone could ward off nightmares and provide a shield against evil spirits. This belief in its protective qualities contributed to its esteemed status in Egyptian society, where it was mined on the island of Zabargad in the Red Sea, a source that provided peridot for thousands of years.
The gemstone’s journey through history continued across continents and cultures. It was later adopted by the Romans, who valued it for its beauty and clarity. Throughout the Middle Ages, peridot was often confused with emerald due to their similar green coloration, leading to its inclusion in many historical crown jewels and religious artifacts under the name "topaz." Despite these historical misidentifications, peridot's unique properties have always set it apart. Its association with the sun has persisted through the ages, linking the gem to themes of light, warmth, and positivity. This ancient legacy forms the foundation of the gemstone’s modern identity as a birthstone representing strength, good fortune, and happiness.
Geological Formation and Sources
Peridot is a gem variety of the mineral olivine, a common rock-forming mineral found in the Earth's mantle. Its formation is unique among gemstones, as it is one of the few that can be found in the mantle and brought to the surface by volcanic activity. This geological origin contributes to its relative abundance compared to other gemstones. Peridot is also found in pallasite meteorites, which are a type of stony-iron meteorite, making it extraterrestrial in origin as well.
Historically, the primary source of peridot was the island of Zabargad (also known as St. John's Island) in the Red Sea, which was mined by the ancient Egyptians. Today, significant deposits of peridot are found in various locations around the world. Notable sources include the United States (particularly Arizona, New Mexico, and Hawaii), Pakistan, Myanmar, and China. The gemstone's color can vary depending on its source, with the finest peridot displaying a rich, vibrant olive green with no brownish undertones. The availability of peridot from multiple sources helps make it a more accessible gemstone for jewelry, contributing to its popularity as a birthstone gift.
Gemological Properties
Understanding the physical and chemical properties of peridot is essential for appreciating its value and ensuring its proper care. Peridot has a distinct set of characteristics that define it as a gemstone.
Chemical Composition and Structure: Peridot is the gem variety of the mineral olivine, with the chemical formula (Mg, Fe)₂SiO₄. It is a magnesium iron silicate. Its crystal system is orthorhombic. The gem's color is derived from the presence of iron within its chemical structure. The amount of iron directly influences the shade of green, with higher iron content typically resulting in a darker, more olive hue.
Physical Characteristics: - Hardness: On the Mohs scale of mineral hardness, peridot rates between 6.5 and 7. This makes it a relatively durable gemstone, suitable for various types of jewelry. However, it is softer than sapphire or diamond and can be susceptible to scratching if not handled with care. - Cleavage: Peridot has distinct cleavage in two directions, which means it can break along these planes if struck with sufficient force. This property requires careful cutting and setting to avoid damage. - Luster: It exhibits a vitreous (glass-like) luster, giving it a bright and attractive shine when properly polished. - Refractive Index: The refractive index of peridot ranges from 1.65 to 1.69, contributing to its brilliance and sparkle.
Color and Clarity: The most valued color for peridot is a rich, vibrant olive green to a pure lime green, free from brownish or yellowish tints. Peridot is known for its good clarity, often containing inclusions that are characteristic of the stone, such as "lily pad" inclusions. Unlike many other gemstones, peridot is not typically treated to enhance its color or clarity, which adds to its appeal as a natural and untreated gem.
Cut and Carat Weight: Peridot is cut into a variety of shapes to maximize its color and brilliance. Common cuts include round, oval, emerald, and cushion cuts. The gemstone's clarity and color allow for larger carat weights to be used in jewelry, making it an excellent choice for statement pieces like cocktail rings and pendants. Peridot is available in a wide range of sizes, from small accent stones to substantial centerpieces.
