Whether worn as jewelry or used in meditative practices, Peridot continues to captivate gemstone enthusiasts and spiritual seekers alike. This article delves into the geological, historical, symbolic, and practical aspects of Peridot, offering a comprehensive guide to this extraordinary stone.
History and Lore
Peridot’s history spans millennia, with its presence documented in ancient civilizations and religious texts. One of the earliest known references to Peridot dates back to the ancient Egyptians, who called it the “gem of the sun.” The Egyptians believed the gemstone had divine origins, attributing to it protective and purifying powers. It was often used in religious rituals and believed to ward off evil spirits and nightmares. Some legends even suggest that Peridot was the stone used in the golden caskets of mummies, a testament to its revered status.
In ancient Rome, Peridot was known as the “Evening Emerald” because of its striking green color that retained its vibrancy under candlelight. Roman nobles and scholars wore it in rings and pendants, believing it to be a source of wisdom and insight. The stone’s continued luminosity in the dark was considered a sign of its mystical power.
Peridot also appears in the Bible. According to some interpretations, one of the twelve stones on the High Priest Aaron’s breastplate was Peridot. This connection to sacred tradition further elevated its status as a stone of spiritual significance and divine protection.
The Middle Ages brought with it a different set of beliefs. During this period, Peridot was often used in amulets and charms for protection. Knights and soldiers wore it into battle, believing it granted them strength and courage. It was also considered a stone of healing, particularly for those suffering from digestive issues or emotional distress.
In modern times, Peridot has retained much of its historical allure while also gaining popularity as a birthstone. It was officially recognized as the August birthstone by the American National Association of Jewelers in 1912, a decision that reflected its long-standing cultural and aesthetic value.
Geological Formation and Sources
Peridot is a silicate mineral of the olivine family, and its striking green color is due to the presence of iron in its crystal structure. The name "peridot" is believed to derive from the Arabic word faridat, meaning “gem,” which reflects its ancient recognition as a precious stone.
Geologically, Peridot forms under high pressure and temperature conditions in the Earth's mantle, often in association with volcanic activity. It is typically found in igneous rocks such as basalt and peridotite. Over time, tectonic activity brings these gemstone-rich rocks closer to the Earth’s surface, where erosion and weathering expose the gemstones.
The world’s most significant sources of Peridot include:
Zabargad Island (St. John’s Island), located in the Red Sea, was historically one of the most important sources of Peridot. This island was known for producing high-quality gemstones with deep green tones. The Egyptians referred to it as the “Emerald Isle” and considered it a sacred source of the gem.
Arizona, USA, is another major source of Peridot. The state’s volcanic activity has led to the formation of gem-quality Peridot, particularly in the area of the San Carlos Apache Reservation. This Peridot is known for its vibrant color and affordability, making it a popular choice in jewelry.
Myanmar (Burma), especially in the Mogok region, produces Peridot with a range of colors, from pale to deep green. The gemstones from this region are often of high clarity and brilliance.
Brazil, particularly in the state of Minas Gerais, is another significant producer of Peridot. The gemstones from Brazil often exhibit a rich olive-green color and are used in both jewelry and decorative items.
India and China also produce Peridot, with Indian stones typically being lighter in color and Chinese stones known for their clarity and affordability.
The availability of Peridot in various parts of the world has made it a widely accessible gemstone. Unlike many other gemstones, Peridot is not limited to a few exclusive locations, and its abundance contributes to its relatively lower cost and widespread use in jewelry.
Gemological Properties
Peridot is a fascinating gemstone not only for its beauty but also for its unique gemological characteristics. Here is a detailed overview of its key properties:
Chemical Formula: (Mg,Fe)₂SiO₄
Peridot is a member of the olivine family, and its color is determined by the amount of iron in its chemical structure. The more iron present, the deeper the green color.Hardness: 6.5 to 7 on the Mohs scale
Peridot is relatively hard, making it suitable for jewelry, although it is not as durable as diamonds or sapphires. It can be scratched by harder materials and is vulnerable to impact, so care should be taken when wearing or cleaning Peridot jewelry.Refractive Index: 1.65 to 1.85
The refractive index of Peridot is relatively high, contributing to its brilliance and luster. This property makes it appear lively and vibrant in jewelry settings.Specific Gravity: 3.3 to 4.3
Peridot is a relatively heavy gemstone for its size, which can be a helpful characteristic in identification.Color: Green
Peridot is unique in that it is one of the few gemstones that occur in only one color—green. The shade of green can vary from a pale yellow-green to a deep olive, depending on the amount of iron in the stone.Clarity: Typically included
Peridot is often found with inclusions, which are natural imperfections that form during its geological creation. These inclusions can include tiny crystals or flecks of other minerals. While some inclusions can affect the stone’s clarity and value, many are considered part of the gemstone’s natural charm.Cut: Round, oval, cushion, and other faceted shapes
Peridot is commonly cut into brilliant round or oval shapes to maximize its fire and brilliance. It is also sometimes cut into cushion or other fancy shapes for unique jewelry designs.Luster: Vitreous (glassy)
Peridot has a glassy luster that enhances its visual appeal. When properly cut and polished, it can display a beautiful sparkle.
These properties make Peridot a versatile and attractive gemstone. Its unique color and relatively high hardness make it suitable for a wide range of jewelry applications, from rings and pendants to earrings and bracelets. However, due to its inclusions and sensitivity to impact, it is best suited for everyday wear with proper care and handling.
