History and Lore
The history of August birthstones is as rich and varied as the gemstones themselves. These stones have been cherished for centuries, often associated with protective powers, good fortune, and emotional healing.
Peridot: The “Evening Emerald”
Peridot, the traditional birthstone for August, has a long and storied past. Known in ancient Egypt as the “gem of the sun,” Peridot was believed to have been formed by the rays of the sun and was thought to bring protection and good fortune. The gemstone's vibrant green color and natural glow made it a favorite among Egyptian pharaohs, who often wore it as a symbol of power and prosperity.
Peridot was also popular in the Middle Ages, where it was used in religious jewelry and believed to have healing properties. Today, Peridot is still valued for its beauty and is considered a stone of renewal and positivity. It is often associated with summer, as its warm green hue evokes the lushness of the season.
Spinel: The Overlooked Gem
Spinel is a relatively recent addition to the list of August birthstones. Officially recognized as an alternative in 2016 by the American National Association of Jewelers, Spinel has long been mistaken for other gems like ruby and garnet due to its similar appearance in certain colors. Historically, some of the most famous "rubies" in royal collections were actually red Spinel.
Spinel is known for its brilliance, durability, and wide range of colors. From fiery red to deep blue and vibrant pink, Spinel offers a spectrum of hues that make it a versatile and attractive choice for August. It has also been associated with energy, vitality, and emotional balance, making it a meaningful stone for those who value positivity and strength.
Sardonyx: The Ancient Protector
Sardonyx is one of the oldest known August birthstones and has been used for centuries in various cultures. Made from alternating layers of sard and onyx, Sardonyx is known for its striking red and white bands, which give it a unique and elegant appearance. It was especially popular in ancient Egypt, Greece, and Rome, where it was used in amulets and seals.
Sardonyx has long been associated with protection, particularly in matters of love and marriage. A famous Gregorian birthstone poem from the Middle Ages even suggests that those born in August who do not wear Sardonyx may live a life of unrequited love. In addition to its protective qualities, Sardonyx is also believed to bring strength and confidence to its wearer.
Geological Formation and Sources
Each of these gemstones is formed through unique geological processes, and they are found in various parts of the world. Understanding their formation and origin provides insight into their rarity and value.
Peridot
Peridot is a type of olivine, a mineral that forms in the Earth’s mantle and is brought to the surface through volcanic activity or meteorite impacts. This makes Peridot one of the few gemstones that can be found in both terrestrial and extraterrestrial sources. Some of the most notable Peridot deposits are found in Zimbabwe, Brazil, and the United States, particularly in Arizona and Hawaii.
Peridot’s green color is due to its chemical composition, which includes magnesium and iron. Unlike many other gemstones, Peridot does not rely on trace elements to create its color—its green is intrinsic to its structure. This gives it a consistent and vibrant appearance, making it a popular choice for jewelry.
Spinel
Spinel is a mineral composed of magnesium aluminum silicate, and it is found in a wide range of colors depending on the trace elements present. Red Spinel, for example, gets its color from chromium, while blue Spinel is colored by iron or cobalt.
Spinel is formed in mafic igneous rocks and is often found in metamorphic rocks as well. Notable sources of Spinel include Afghanistan, Myanmar, and Sri Lanka, where high-quality gemstones are mined. Spinel is also found in Brazil, Madagascar, and Thailand, where it is often used in both fine and fashion jewelry due to its durability and brilliance.
Sardonyx
Sardonyx is a type of chalcedony, a form of microcrystalline quartz that is known for its banding and durability. Sardonyx is formed when layers of sard (a reddish-brown variety of quartz) and onyx (a black or white variety of quartz) are deposited together in sedimentary rock formations.
Sardonyx is primarily found in India, Brazil, and the United States. It has also been historically mined in Egypt and the Middle East, where it was used in ancient jewelry and amulets. The gemstone’s banded appearance and hardness make it ideal for carving, and it has been used to create intricate seals, cameos, and pendants.
