August boasts a remarkable selection of birthstones: peridot, spinel, and sardonyx. These gems, each with a unique history and captivating beauty, offer a diverse range of choices for those born in the eighth month of the year. From ancient origins as symbols of protection and prosperity to modern appreciation for their vibrant colors and metaphysical properties, these stones hold a significant place in both gemology and cultural lore. This article will explore the history, geological origins, gemological properties, and symbolism associated with each of these August birthstones.
A Historical Tapestry
The history of August birthstones is interwoven with ancient civilizations and evolving beliefs. Sardonyx holds the distinction of being the original birthstone for August, with a history stretching back over 4,000 years. Ancient Egyptians utilized sardonyx to create amulets and seals, often intricately carved with hieroglyphs, believing the stone offered protective qualities. Romans similarly valued sardonyx, crafting cameos depicting deities, emperors, and significant figures, showcasing the stone’s artistic potential and its status as a symbol of wealth and power. During the Renaissance, it was believed to enhance eloquence, making it a favored stone among public speakers.
Peridot’s story is equally rich, though often intertwined with misidentification. Throughout history, this gem was frequently mistaken for emerald and topaz. The Red Sea island of Topazios, from which the name “topaz” originates, was actually a significant source of peridot. Some historians speculate that even Cleopatra’s famed emerald collection may have consisted largely of peridot. Egyptian pharaohs prized peridot for its protective qualities, and it has been mined for thousands of years.
Spinel, while historically often confused with ruby, has a more recent rise to prominence as a recognized August birthstone. For centuries, red spinel was mistaken for ruby, particularly in historical jewelry. It wasn’t until more recent advancements in gemological science that spinel was recognized as a distinct and valuable gemstone in its own right. Today, collectors appreciate spinel for its rarity and diverse range of vibrant colors.
Geological Formation and Sources
The formation and sourcing of these birthstones vary considerably. Peridot is unique in that it can be found in both terrestrial and extraterrestrial origins. It is formed under extreme conditions, often found in hardened lava carried from deep within the Earth’s mantle, and has even been discovered in meteorites.
Spinel is sourced from several locations worldwide, including Tajikistan, Myanmar, Sri Lanka, Vietnam, Tanzania, and Pakistan. Myanmar is particularly renowned for producing spinel in arresting colors like hot pink and red. Sri Lanka is known for its blue, pink, and purple spinel, found in the rolling hills of the Central Highlands and river gravels. Northern Vietnam’s Luc Yen region yields spinel in deep red, purple, pink, vivid blue, violet, and violet-blue hues. Tanzania has also become a source of pinkish and orangy-red spinel since its discovery in 2007.
Sardonyx, a variety of chalcedony, is formed through the layering of red and white bands. The name itself derives from the Greek words "sard" (reddish-brown chalcedony) and "onyx" (black chalcedony), reflecting its distinctive appearance. Specific geological origins for sardonyx beyond its composition are not detailed in the provided sources.

Each of these August birthstones possesses distinct gemological properties. Peridot is the yellowish-green to greenish-yellow gem variety of the mineral olivine.
Spinel’s defining characteristic is its wide range of colors, including intense red, vivid pink, orange, purple, violet, blue, and bluish-green. The Latin origin of its name, "spina," meaning "thorn," refers to its structural shape.
