Whether you are an August-born individual, a jewelry enthusiast, or a gemstone scholar, this article provides a comprehensive overview of the stones that define the month of August in the world of birthstones.
History and Lore of August Birthstones
The history of August’s birthstones is as varied and colorful as the gems themselves. Peridot, the most well-known of the trio, has a long and storied past. Ancient Egyptians referred to it as the “Evening Emerald” and believed it to be a protective stone. The gem was so highly valued by Egyptian pharaohs that they sourced it from the island of Topazios in the Red Sea. Some historians even speculate that Cleopatra’s famed emerald collection might have been composed of peridot, due to the confusion between the two stones in ancient times. Peridot’s association with the sun and its vibrant green color have made it a symbol of vitality and renewal across many cultures.
Spinel, though less well-known than peridot, has its own rich history. For centuries, it was mistaken for ruby and other precious stones, including garnet and topaz. Its confusion with ruby led to its underappreciation until recently, when it was rediscovered as a gemstone in its own right. The name “spinel” is derived from the Latin spinum, meaning “thorn,” a reference to the sharp, pointed crystals in which it often forms. Spinel has been used in royal jewelry, and some of the most famous historical pieces—such as the "Black Prince’s Ruby" in the Tower of London—are actually red spinel. The gem’s versatility in color and its fiery brilliance have made it a popular choice in modern jewelry, especially for those seeking an alternative to traditional red gems like ruby.
Sardonyx, the original August birthstone, has a history that stretches back more than 4,000 years. This banded chalcedony is composed of alternating layers of red-brown and white, and its name is derived from the Greek words sardion (a type of red stone) and onyx (a type of banded agate). Ancient civilizations, including the Egyptians and Romans, used sardonyx for amulets and seals, believing it to offer protection, courage, and stable relationships. The stone was particularly valued for its grounding properties and was often worn by warriors and leaders to instill strength and resilience. Sardonyx’s enduring popularity in ancient and medieval times reflects its deep spiritual and practical significance.
Together, these three gemstones form a compelling narrative of August’s birthstone heritage. Each stone carries with it a legacy of beauty, symbolism, and historical importance that continues to captivate gemstone enthusiasts and historians alike.
Geological Formation and Sources of August Birthstones
The geological formation and sources of August’s birthstones reflect the diverse and fascinating ways in which nature creates gemstones. Each of these stones—peridot, spinel, and sardonyx—has unique origins and geographic distributions that contribute to their rarity and value.
Peridot is one of the few gemstones that can be found in both terrestrial and extraterrestrial sources. It is formed in the Earth’s mantle and brought to the surface through volcanic activity. Peridot is commonly found in basaltic lava flows and in meteorites, particularly in pallasites, which are a type of stony meteorite that contain olivine crystals. The most significant sources of peridot today include the United States (especially in Arizona), China, Pakistan, and the island of Zabargad in the Red Sea. Zabargad, also known as Topazios, is historically significant as one of the earliest known sources of the gem and continues to produce high-quality peridot.
Spinel is a mineral that forms in a variety of geological environments, including metamorphic and igneous rocks. It is often found in association with other gemstones, such as ruby and sapphire, and is commonly discovered in alluvial deposits—areas where water has transported and concentrated the gem over time. The most important sources of spinel include Burma (Myanmar), Sri Lanka, Tanzania, and Vietnam. Spinel has been historically underappreciated due to its frequent misidentification with other gemstones, but its clarity, brilliance, and range of colors have made it a sought-after gem in recent years.
Sardonyx is a type of chalcedony, a microcrystalline form of quartz. It forms in sedimentary environments and is often found in areas where silica-rich solutions have filled cracks and cavities in rock formations. Sardonyx is most commonly found in India, Brazil, and the United States, particularly in the state of Oregon. The red-brown layers of sardonyx are caused by the presence of iron oxides, while the white bands result from pure quartz. The stone’s banded pattern and durability make it ideal for carving and engraving, which explains its historical use in seals and amulets.
The geological diversity of these gemstones contributes to their unique characteristics and availability. While peridot and spinel are relatively rare in high-quality forms, sardonyx is more commonly available, especially in carved pieces. Understanding the sources and formation of these stones not to only appreciate their beauty but also to recognize the natural processes that create them.
Gemological Properties of August Birthstones
Understanding the gemological properties of August’s birthstones—peridot, spinel, and sardonyx—is essential for appreciating their beauty, durability, and suitability for various types of jewelry. Each of these gemstones has distinct physical and optical characteristics that influence their appearance and value.
Peridot is a silicate mineral with the chemical formula (Mg,Fe)₂SiO₄. It is known for its vibrant green color, which ranges from yellow-green to deep olive-green. The gemstone has a hardness of 6.5 to 7 on the Mohs scale, making it relatively durable but still susceptible to scratches and damage from hard impacts. Peridot is isotropic, meaning it does not exhibit double refraction, and has a refractive index of approximately 1.65 to 1.70. It is also pleochroic, meaning it can display different colors depending on the angle of light. Peridot is typically transparent to translucent and is often cut in a brilliant or mixed style to enhance its luster and fire.
Spinel is an oxide mineral with the chemical formula MgAl₂O₄. It is known for its wide range of colors, including red, pink, orange, blue, and even black. Spinel has a hardness of 8 on the Mohs scale, making it more durable than peridot. It is isotropic and has a refractive index of approximately 1.718 to 1.834, depending on its composition. Spinel is also known for its high dispersion, which gives it a fire similar to that of diamond. The gemstone is typically transparent to translucent and is often cut in a brilliant or cushion style to maximize its brilliance and color.
Sardonyx is a type of chalcedony, which is a microcrystalline form of quartz. It has the chemical formula SiO₂ and is composed of alternating layers of sard (a reddish-brown chalcedony) and onyx (a white chalcedony). Sardonyx has a hardness of 6.5 to 7 on the Mohs scale, making it relatively durable. It is isotropic and has a refractive index of approximately 1.53 to 1.54. Sardonyx is typically translucent to opaque and is often carved or engraved rather than faceted, as its banded pattern is best displayed in cabochons or intaglios.
The gemological properties of these stones influence their use in jewelry and their care. Peridot and spinel are well-suited for rings and pendants due to their durability, while sardonyx is often used for carved pieces, seals, and beads. Understanding these properties helps in selecting the right gemstone for a particular type of jewelry and in ensuring its longevity and beauty.
