The August Birthstone Bear: A Symbol of Warmth and Protection
While the gemstones themselves are the primary focus of the August birthstone tradition, the August Birthstone Bear offers a unique and tangible way to celebrate this month's meaningful stones. This plush bear, designed with a blend of soft polyester and a peridot green heart, serves as a keepsake that embodies the spirit of the August gemstone. The bear is adorned with an inspirational tag that reads "brave," a word often associated with peridot, the most prominent of the August birthstones.
The bear’s design includes subtle nods to the earthy tones of peridot—white, gray, and tan—while the peridot green nose and heart provide a visual representation of the gemstone’s radiant hue. The bear is not only a comforting companion but also a symbol of protection and emotional support, drawing from the ancient belief that peridot could ward off nightmares and offer courage in times of need.
Ideal for birthdays, baby showers, or even as a thoughtful gift during difficult times, the August Birthstone Bear is more than just a decorative item—it is a meaningful token of love and strength. The bear’s dimensions (3.5" W x 2" D x 8.5" H) and soft, surface-washable fabric make it both practical and durable, ensuring it can be enjoyed by recipients of all ages.
Historical Lore and Cultural Significance
Peridot: The “Sun Gem” of Antiquity
Peridot has been cherished for thousands of years, with its earliest known use dating back to ancient Egypt. The Egyptians referred to peridot as the “gem of the sun,” believing it to be a gift from the sun god, Ra. It was often used in jewelry and amulets, and was thought to bring protection and good fortune. Ancient Egyptians also believed that peridot could ward off nightmares and promote peace during sleep.
In Hawaiian mythology, peridot was believed to have been formed from the tears of the volcano goddess Pele. According to legend, the bright green crystals found in volcanic rock were the result of her weeping. This myth underscores the connection between peridot and the natural forces of the earth, reinforcing its role as a stone of transformation and renewal.
The gemstone’s vibrant green color, ranging from olive to lime, has also made it a popular choice in jewelry across cultures. It was commonly used in ancient Roman and Greek jewelry, often set in gold to enhance its brilliance. The gem’s affordability and availability further contributed to its widespread use, making it a gemstone accessible to many.
Sardonyx: The Stone of Courage and Clarity
Sardonyx, a banded variety of chalcedony, is composed of alternating layers of sard (a reddish-brown quartz) and onyx (a white or black chalcedony). This distinctive pattern gives the stone an earthy, striped appearance that has been used in carvings and cameos since ancient times.
The Romans were particularly fond of sardonyx, using it to create detailed cameos and seals. These carvings were often used to stamp wax on official documents or as personal ornaments. Sardonyx was also believed to have protective properties, especially in battle. Roman soldiers would carry sardonyx amulets to invoke courage and clarity in times of conflict. The stone was also associated with communication and truth, making it a favored choice for those in leadership roles or public speaking.
Sardonyx’s layered structure and hardness (ranging from 6.5 to 7 on the Mohs scale) make it a durable and versatile gemstone. Its warm, earthy tones complement a wide range of jewelry styles, from classical cameos to modern pendants and rings. The stone’s ability to be carved into intricate designs has made it a favorite among artisans and jewelers.
Spinel: The Misunderstood Gem
Spinel is a gemstone that has often been mistaken for other more well-known gems, including rubies and sapphires. In fact, some of the most famous "rubies" in royal crowns and jewelry collections were later identified as spinel. For example, the "Black Prince’s Ruby," a prominent feature in the British Crown Jewels, is actually a large red spinel.
Spinel comes in a wide range of colors, including deep red, pink, orange, and even blue. Its brilliance and clarity are often comparable to that of ruby or sapphire, but it is generally more affordable and less prone to inclusions. Spinel is a durable gemstone with a hardness of 8 on the Mohs scale, making it suitable for everyday wear in rings, earrings, and pendants.
Historically, spinel was highly valued in the royal courts of Europe and Asia. It was believed to bring vitality and emotional balance, making it a popular choice for those in positions of power or leadership. The gemstone’s vibrant colors and versatility have made it a modern favorite among designers and collectors, who appreciate its beauty and affordability.
Geological Formation and Sources
Peridot
Peridot is a silicate mineral that forms in the Earth’s mantle and is brought to the surface through volcanic activity. It is commonly found in basaltic lava flows and in xenoliths (fragments of the Earth’s mantle) brought to the surface by volcanic eruptions. Peridot is also found in meteorites, making it one of the few gemstones that can originate from space.
The most significant sources of peridot include:
- Zabargad Island (St. John’s Island) in the Red Sea, known for producing some of the finest peridot in the world.
- Arizona, USA, particularly in the San Carlos Apache Reservation, which is a major source of high-quality peridot.
- Madagascar, Myanmar, and China, which also produce notable quantities of the gemstone.
Peridot’s chemical formula is (Mg,Fe)₂SiO₄, and it belongs to the olivine family of minerals. Its hardness ranges from 6.5 to 7 on the Mohs scale, making it relatively durable but not as hard as diamonds or corundum (ruby and sapphire). Peridot is typically transparent to translucent and has a vitreous luster.
Sardonyx
Sardonyx is a type of chalcedony, which is a microcrystalline variety of quartz. It forms when silica-rich solutions seep into rock cavities and gradually deposit layers of quartz. The alternating bands of sard and onyx create the stone’s distinctive striped appearance.
The primary sources of sardonyx include:
- India, particularly in the state of Rajasthan, where it has been mined for centuries.
- Brazil, where the stone is found in a variety of colors and patterns.
- Mexico, known for producing sardonyx with rich red and white bands.
- Ethiopia and Madagascar, which also yield high-quality sardonyx.
Sardonyx has a hardness of 6.5 to 7 on the Mohs scale, making it suitable for a variety of jewelry applications. It is often used in carvings, cameos, and engraved designs due to its fine grain and ability to take a high polish.
Spinel
Spinel is a mineral composed of magnesium aluminum silicate, with the chemical formula MgAl₂O₄. It forms in both igneous and metamorphic rocks and is often found in association with other gemstones such as ruby and sapphire.
The most significant sources of spinel include:
- Myanmar (Burma), particularly in the Mogok region, which is known for producing vibrant red and pink spinel.
- Afghanistan, where large, high-quality spinel crystals are found.
- Vietnam and Sri Lanka, which also produce notable quantities of the gemstone.
- Brazil and Madagascar, which are emerging as important sources of spinel in recent years.
Spinel has a hardness of 8 on the Mohs scale, making it highly durable and suitable for everyday wear. It is also known for its excellent clarity and brilliance, which are enhanced by proper cutting and polishing.

Care and Cleaning

Peridot
Peridot is relatively soft and can be easily scratched by harder materials. It is also sensitive to heat and harsh chemicals. To clean peridot, use a soft, lint-free cloth and warm, soapy water.
