History and Lore
The history of the August birthstones is as rich and varied as the stones themselves. Peridot, for example, has been known to humanity for thousands of years. Ancient Egyptians referred to it as the “gem of the sun” and believed it to be formed from solidified rays of the sun. It was also used in religious artifacts and was thought to bring protection to its wearer. Sardonyx, a type of chalcedony, was favored by the ancient Greeks and Romans for its banded appearance and was often used in signet rings, where it was believed to offer protection and good fortune. Spinel, while less ancient in recorded history, has been highly valued for its beauty and has been mistaken for ruby and other precious stones due to its similar appearance.
These stones have also found their way into various cultural practices and beliefs. Peridot is often associated with emotional healing and renewal, making it a popular choice for those seeking a calming influence. Sardonyx is considered a stone of strength and protection, particularly useful for those undergoing life changes or seeking emotional stability. Spinel, with its vibrant colors, is believed to offer revitalization and protection, making it a versatile gemstone for a variety of purposes.
The journey of these gemstones from their natural origins to their roles in modern jewelry is a testament to their enduring appeal and the rich tapestry of human history that they have woven into their stories.
Geological Formation and Sources
Understanding the geological formation and sources of these gemstones is essential for anyone interested in jewelry making or collecting. Each of the August birthstones has a unique formation process and specific locations where they are found, which influence their properties and availability.
Peridot
Peridot is formed in the Earth's mantle and is brought to the surface through volcanic activity. It is primarily found in olivine-rich rocks, particularly in areas with volcanic history. The most significant sources of peridot include Arizona in the United States, Myanmar, and China. Peridot is also found in meteorites, making it one of the few gemstones that can be considered extraterrestrial. Its formation process results in a gemstone with a warm green color, which is due to the presence of iron in its chemical composition (MgFeSiO₄).
Sardonyx
Sardonyx is a type of chalcedony, a form of quartz, and is composed of layers of sard (reddish-brown chalcedony) and white onyx. This banded appearance is formed through the deposition of silica-rich water in sedimentary rock layers over time. Sardonyx is found in various parts of the world, including India, Brazil, and the United States. The most notable sources are in the Indian state of Rajasthan and the state of Arizona in the U.S. The formation process of sardonyx results in a gemstone with a waxy to vitreous luster and a hardness of 6–7 on the Mohs scale.
Spinel
Spinel is formed in igneous and metamorphic rocks and is often found in pegmatite and marble deposits. The most significant sources of spinel include Myanmar, Sri Lanka, and Vietnam. Spinel is known for its wide range of colors, from deep red to vivid pink and even blue and colorless. The color variation is due to the presence of different trace elements, such as chromium for red and cobalt for blue. Spinel has a hardness of 8 on the Mohs scale, making it a durable gemstone suitable for a variety of jewelry designs.
Gemological Properties
A detailed understanding of the gemological properties of peridot, sardonyx, and spinel is essential for both gemologists and jewelry buyers. These properties include color, clarity, hardness, and chemical composition, all of which affect the stone's value and suitability for different types of jewelry.
Peridot
Peridot exhibits a range of colors from yellow-green to deep olive green. It is typically transparent and has a vitreous luster. The hardness of peridot ranges from 6.5 to 7 on the Mohs scale, making it relatively soft compared to other gemstones. This hardness level means that peridot is suitable for pendants and earrings but may be more susceptible to scratches in rings or bracelets that are worn frequently.
Sardonyx
Sardonyx is known for its banded appearance, with red-brown and white stripes. It is often opaque or semi-transparent and has a waxy to vitreous luster. The hardness of sardonyx ranges from 6 to 7 on the Mohs scale, making it a durable gemstone suitable for a variety of jewelry designs, including rings and bracelets. Sardonyx is composed of silicon dioxide (SiO₂), which contributes to its stability and durability.
Spinel
Spinel is available in a wide range of colors, including red, pink, blue, and colorless. It is typically transparent to semi-transparent and has a vitreous luster. Spinel has a hardness of 8 on the Mohs scale, making it a durable gemstone suitable for rings, pendants, and other types of jewelry. The chemical composition of spinel is magnesium aluminum oxide (MgAl₂O₄), which contributes to its stability and brilliance.
The following table summarizes the key gemological properties of the August birthstones:
| Property | Peridot | Sardonyx | Spinel |
