History and Lore
Peridot: The Sun's Gift
Peridot has been cherished for millennia, with its earliest known use dating back to ancient Egypt. The gem was often mistaken for an emerald due to its rich green hue, but its distinct brilliance and warmth soon set it apart. In ancient times, peridot was believed to offer protection against nightmares and bring the wearer happiness and strength. It was also thought to be a sacred stone, with some legends suggesting that peridot was formed from the tears of a fallen star or the solidified fire of the sun itself.
During the Middle Ages, peridot was a popular gemstone in Europe, especially in the British Isles and the Holy Roman Empire. It was often used in ecclesiastical jewelry and was believed to have healing properties. The stone was also associated with the sun, and its vibrant green color symbolized growth, renewal, and vitality. This association with the sun and nature made peridot a popular choice for those seeking to harness positive energy and emotional balance.
Sardonyx: The Stone of Strength and Protection
Sardonyx, a banded form of chalcedony, has a long and storied history that dates back to ancient civilizations. The stone's distinctive red-brown and white stripes have made it a favorite in the creation of cameos and intaglios, especially during the Roman Empire. Sardonyx was believed to offer protection and strength, making it a popular choice for warriors and leaders. It was also associated with courage and stable relationships, symbolizing the union of fire and earth.
In ancient Greece and Rome, sardonyx was used to create intricate seals and signet rings, which were used to mark documents and authenticate correspondence. These rings were not only functional but also carried symbolic meaning, with the red and white bands representing the duality of life and death, as well as the balance between action and reflection.
Sardonyx continued to be valued in the medieval period and beyond, appearing in both religious and secular contexts. It was often used in jewelry to represent grounding and emotional stability, and it was believed to help the wearer remain focused and centered in times of stress or uncertainty.
Spinel: A Gem of Royal Elegance
Spinel is a gemstone that has been admired for centuries, particularly in royal courts and among the nobility. Despite its long history, it was often mistaken for ruby due to its deep red color. Some of the most famous “rubies” in royal collections, including the “Black Prince’s Ruby” in the British Crown Jewels, are actually spinels. This misidentification highlights the gem's similarity in appearance to ruby and its role as a gemstone of prestige and power.
Spinel comes in a wide range of colors, including red, pink, blue, and even colorless, but the red and pink varieties are the most commonly used in August birthstone jewelry. The gem was highly prized in ancient times, particularly in Asia, where it was used in imperial jewelry and sacred artifacts. Its durability and brilliance made it a favorite among jewelers and collectors, and it was often used in rings, pendants, and other fine jewelry pieces.
In the modern era, spinel has gained renewed appreciation for its beauty and versatility. It is a durable gemstone with a hardness of 8 on the Mohs scale, making it suitable for a wide range of jewelry designs, including rings and bracelets. Spinel is found in various parts of the world, including Myanmar, Sri Lanka, and Vietnam, and its availability in a range of colors allows for creative and expressive jewelry designs.
