August boasts a remarkable selection of birthstones: peridot, spinel, and sardonyx. While peridot is often considered the primary stone for this month, the inclusion of spinel and sardonyx offers a rich tapestry of history, symbolism, and color for those born in August. These gemstones represent a fascinating journey through ancient traditions and modern appreciation, each with a unique story to tell.
A Historical Perspective
The origins of August birthstones are deeply rooted in history. The month itself is named after Augustus Caesar, the first Roman Emperor, originally known as Sextilis. The earliest recognized August birthstone is sardonyx, with a history stretching back over 4,000 years. It was prominently featured in ancient civilizations, appearing in the high priest’s breastplate as described in biblical texts and utilized in amulets, cameos, and seals by the Greeks and Romans, who believed it conferred strength and victory.
Peridot’s history is also ancient, though often intertwined with misidentification. Ancient Egyptians mined peridot on the island of Zabargad, referring to it as the “gem of the sun” due to its brilliant shine. Historical accounts suggest that Cleopatra’s famed emerald collection may have actually consisted largely of peridot. Interestingly, the island historically known as Topazios, from which the name “topaz” originates, was actually a source of peridot, leading to a long-standing confusion between the two gems. Some scholars believe references to topaz in historical texts may, in fact, be describing peridot.
Spinel is the newest addition to the August birthstone family, officially gaining recognition in 2016. However, its history is not new; for centuries, red spinel was often mistaken for ruby, a gem with which it shares a similar appearance. It wasn’t until more recent advancements in gemological science that spinel was properly identified as a distinct mineral species.
Geological Formation and Sources
Peridot is a fascinating gem formed under extreme conditions. It is a variety of the mineral olivine, originating deep within the Earth’s mantle and brought to the surface through volcanic activity. It can also be found in meteorites, offering a truly extraterrestrial origin for some specimens.
Spinel forms in metamorphic rocks and is often found alongside other gemstones like ruby and sapphire. Its occurrence is less common than that of ruby and sapphire, contributing to its relative rarity.
Sardonyx is a banded form of chalcedony, a variety of quartz. It is created through the layering of different colors of silica in volcanic lava.
Gemological Properties
Peridot is uniquely consistent in color, always appearing in shades of green, ranging from yellow-green to olive green. This color is attributed to the presence of iron within its composition. It is a yellowish green to greenish yellow gem variety of the mineral olivine.
Spinel boasts a wide range of colors, including red, blue, purple, and black, often rivaling the vibrancy of ruby and sapphire. Its crystal structure differs from ruby and sapphire, classifying it as a distinct mineral species.
Sardonyx is characterized by its banded appearance, typically featuring layers of red-brown and white. This banding is a result of the different silica layers during its formation.

Symbolism and Metaphysical Beliefs
Throughout history, these August birthstones have been imbued with symbolic meaning. Sardonyx has long been associated with strength, courage, and protection, making it a favored material for amulets and seals. Ancient Greeks and Romans believed it enhanced communication skills and brought victory in battle.
Peridot is believed to bring abundance, protection, and positivity to its wearer. Ancient Egyptians considered it a “gem of the sun,” believing it possessed magical powers.
Spinel, while a more recent addition to the birthstone list, is associated with revitalization and hope. Its vibrant colors are thought to inspire passion and creativity.
Care and Cleaning
The provided sources offer limited information regarding the specific care and cleaning of these gemstones. However, given peridot’s composition and hardness, it is likely susceptible to scratches and should be handled with care. Spinel and sardonyx, being relatively durable, can likely withstand regular wear, but should still be protected from harsh chemicals and extreme temperatures. General gemstone cleaning practices, such as using warm soapy water and a soft brush, are recommended.
The Modern Appeal
Today, the choice of August birthstone allows for a diverse range of options. Peridot remains a popular choice, celebrated for its unique green hue and historical significance. Spinel has gained recognition as a beautiful and affordable alternative to ruby and sapphire, offering vibrant color and brilliance. Sardonyx, while less commonly featured in modern jewelry, continues to appeal to those seeking a connection to ancient traditions and symbolism.
Those born in August are often described as strong-willed, practical, and natural leaders. The availability of three distinct birthstones allows individuals to choose a gem that resonates with their personality and style.
Conclusion
The August birthstones – peridot, spinel, and sardonyx – represent a captivating blend of history, geology, and symbolism. From the ancient mines of Egypt to the volcanic depths of the Earth, these gems have captivated civilizations for millennia. Whether seeking a traditional connection to the past, a vibrant splash of color, or a symbol of strength and protection, the August birthstones offer a legacy in stone for those born under the summer sun.
