History and Lore
The tradition of birthstones dates back thousands of years, with roots in ancient civilizations that attributed specific powers and meanings to gemstones based on the month of birth. August is no exception, with its birthstones having been treasured for centuries.
Sardonyx: The Original August Birthstone
Sardonyx is the oldest of the three, with a history that stretches back more than 4,000 years. It is mentioned in the Bible as one of the foundation stones of Jerusalem and as one of the gems on the high priest’s breastplate in the Book of Exodus. Its distinctive banded appearance—featuring alternating layers of sard (a reddish chalcedony) and onyx (a white or gray chalcedony)—has made it a popular gem for carving and engraving. Sardonyx was highly valued in ancient Egypt and Rome, where it was used to create cameos and intaglios that depicted religious, mythological, and heraldic imagery.
Peridot: The Radiant Green Gem
Peridot has a long and storied history, often mistaken for other green gems like emerald or topaz. The name "peridot" is derived from the Arabic word "faridat," meaning "gem." In ancient times, peridot was believed to possess protective powers, shielding its wearer from negative energy and evil spirits. It was also associated with wealth, success, and spiritual growth. One of the most famous historical uses of peridot is found in the Shrine of the Three Holy Kings in Cologne Cathedral, where 200 carats of the gem were mistakenly identified as emeralds.
Spinel: The Modern Addition
Spinel was only officially recognized as an August birthstone in 2016, but it has a rich history that predates its modern designation. For centuries, red spinel was mistaken for ruby, and some of the most famous "rubies" in history are actually spinel. The "Black Prince’s Ruby," set in the crown of the British monarch, is a prime example. Spinel is now gaining popularity as a more affordable and ethically sourced alternative to ruby and other precious stones, making it a fitting addition to the August birthstone list.
The inclusion of these three gemstones in the August birthstone tradition reflects the evolving nature of gemology and jewelry. While sardonyx has deep historical roots, peridot has been appreciated for its beauty and symbolism across many cultures, and spinel has recently been recognized for its rarity and visual appeal.
Geological Formation and Sources
Each of August's birthstones is formed under unique geological conditions, contributing to their distinct appearances and properties.
Peridot
Peridot is a variety of the mineral olivine, which is formed in the Earth's mantle under high heat and pressure. It is brought to the surface through volcanic activity, particularly in areas where lava cools rapidly. Peridot can also be found in meteorites, making it one of the few gemstones with extraterrestrial origins. Notable sources of peridot include Arizona, Hawaii, Myanmar, Pakistan, and the United States. The gemstone is especially abundant in the lava fields of Hawaii, where it is found in the sand along the beaches, earning the area the name "Peridot Beach."
Sardonyx
Sardonyx is a type of chalcedony, a cryptocrystalline form of quartz. It is formed when silica-rich fluids seep into cavities in rocks and cool over time, creating banded patterns. The red layers of sardonyx are due to the presence of iron oxide, while the white or gray layers are composed of onyx. Sardonyx is typically mined in India, Brazil, Madagascar, and the United States. It is relatively abundant and affordable, making it a popular choice for carvings and jewelry.
Spinel
Spinel is a mineral that forms in a variety of colors, including red, blue, pink, and black. It is typically found in metamorphic and igneous rocks, particularly in areas with high heat and pressure. Spinel is mined in several countries, including Burma (Myanmar), Afghanistan, Sri Lanka, and Vietnam. The most famous historical sources of red spinel include the Moghul Empire in India and the Thai Kingdom, where it was highly valued by royalty.
Gemological Properties
The gemological properties of each August birthstone play a crucial role in their appearance, durability, and suitability for jewelry.
Peridot
Peridot is known for its vibrant green color, which ranges from yellow-green to olive-green. It has a refractive index of 1.65 to 1.69 and a specific gravity of 3.32 to 3.37. Peridot has a hardness of 6.5 to 7 on the Mohs scale, making it relatively durable but still susceptible to scratches and chips. It is a uniaxial gemstone, meaning it has one optic axis, and it exhibits strong pleochroism, displaying different colors when viewed from different angles.
Sardonyx
Sardonyx is a banded chalcedony with a hardness of 6.5 to 7 on the Mohs scale. It has a refractive index of 1.48 to 1.53 and a specific gravity of 2.58 to 2.64. The stone is composed of silica (SiO₂) and is typically opaque, with the bands of sard and onyx giving it a distinctive appearance. Sardonyx is known for its ability to take a high polish, making it ideal for carved pieces and engraved jewelry.
Spinel
Spinel is a mineral with a hardness of 8 on the Mohs scale, making it more durable than peridot and sardonyx. It has a refractive index of 1.718 to 1.734 and a specific gravity of 3.6 to 4.0, depending on its composition. Spinel can be found in a wide range of colors, including red, blue, pink, and black. It is a doubly refractive gemstone, meaning it has two optic axes, and it exhibits strong luster and brilliance when cut and polished.

Care and Cleaning
Proper care and cleaning are essential to maintaining the beauty and longevity of August's birthstones. Each gemstone requires specific handling due to its unique properties.
Peridot
Peridot is relatively soft and can be scratched easily. It is also sensitive to heat and sudden temperature changes, which can cause it to fracture. To clean peridot, use a soft cloth and mild soapy water. Avoid using ultrasonic or steam cleaners, as these can damage the stone. Store peridot jewelry separately from harder gems to prevent scratches.
Sardonyx
Sardonyx is more durable than peridot and can withstand normal wear and tear. It can be cleaned with a soft cloth and mild soapy water. It is also safe to use ultrasonic cleaners, but steam cleaning should be avoided. Sardonyx is not sensitive to heat, making it a good choice for everyday wear.
Spinel
Spinel is one of the hardest August birthstones and is highly durable. It can be cleaned with a soft cloth and mild soapy water, and it is also safe to use ultrasonic and steam cleaners. Spinel is not sensitive to heat or chemicals, making it a versatile gemstone for various types of jewelry.
