The article will also provide practical guidance on caring for July birthstone jewelry and offer insights into their relevance in modern jewelry design.
History and Lore
The tradition of birthstones is deeply rooted in historical and cultural practices, with July’s birthstones being no exception. The ruby, in particular, has a long and storied history that spans across civilizations. In ancient India, ruby was known as the "king of precious stones" due to its rarity, hardness (second only to diamond), and beauty. It was also believed to possess mystical powers and was often associated with the life force of blood, symbolizing power and youthful energy.
The name "ruby" comes from the Latin word ruber, meaning "red"—a color long associated with love, passion, and vitality. In medieval Europe, ruby was believed to bestow health, wisdom, wealth, and success in love. Burmese warriors, for example, believed that rubies made them invincible in battle. These beliefs highlight the gemstone's powerful symbolism and its enduring appeal across cultures and time.
Sardonyx, another July birthstone, has its own rich history. This gemstone, a combination of sard and onyx, was used by both the Romans and Greeks in battle. They would carry engraved sardonyx stones featuring images of Mars, the god of war, or Hercules for protection and strength. Additionally, there was an ancient belief that sardonyx could protect against scorpion bites, a notion that aligns with its modern interpretation as a stone of protection and fortitude.
The July birthstones also have connections to zodiac signs. For those born under the sign of Cancer (June 21–July 22), the ruby is the traditional gemstone, while those born under Leo (July 23–August 22) are associated with peridot. These zodiac associations further enrich the lore surrounding July's birthstones, linking them to personal traits and cosmic energies.
Geological Formation and Sources
Ruby, the most renowned July birthstone, is a variety of the mineral corundum. Its deep red color is due to trace amounts of chromium. The more chromium present, the stronger the red hue. The finest rubies display a deep red with a hint of purple, a color known in the trade as "pigeon's blood." This term refers to a particularly vivid and desirable shade that is highly sought after by collectors and jewelers.
Rubies are formed under intense heat and pressure within the Earth's crust, typically in metamorphic rocks such as marble. Over millions of years, these conditions create the crystalline structure of corundum. The presence of chromium during this process imparts the characteristic red color. The most famous ruby-producing regions include Myanmar (Burma), Thailand, Sri Lanka, and Afghanistan. Each region produces rubies with slightly different characteristics, influenced by the geological conditions of the area.
Sardonyx, another July birthstone, is a type of chalcedony composed of layers of sard (a reddish-brown variety of quartz) and onyx (a black or white variety of quartz). This banding creates a striking contrast that makes sardonyx a popular choice for engraved jewelry and cameos. Sardonyx is typically found in sedimentary rocks and is mined in various parts of the world, including India, Brazil, and the United States. The gemstone’s durability and affordability make it a practical choice for jewelry, especially for those who prefer alternative birthstones to ruby.
Other July birthstones such as sapphire, onyx, and carnelian also have distinct geological origins. Sapphires, which can range in color from blue to yellow and green, are another variety of corundum and are found in regions such as Kashmir, Madagascar, and Australia. Onyx is a form of chalcedony that is typically black or white and is often used in mourning jewelry and protective amulets. Carnelian, a reddish-orange chalcedony, is found in India, Brazil, and the United States and is known for its vibrant color and affordability.
The geological diversity of July's birthstones contributes to their unique beauty and appeal. Whether it's the deep red of ruby, the banded patterns of sardonyx, or the warm tones of carnelian, these gemstones offer a wide range of options for jewelry and personal adornment.
Gemological Properties
The gemological properties of July's birthstones provide valuable insights into their durability, appearance, and suitability for jewelry. Ruby, the most prized of these gemstones, is a type of corundum with a hardness of 9 on the Mohs scale. This high hardness makes it resistant to scratches and ideal for use in rings, necklaces, and other frequently worn jewelry. Ruby's refractive index ranges from 1.76 to 1.78, giving it a brilliant sparkle when cut and polished. The best ruby specimens display a deep red color with a slight purple overtone, a quality known as "pigeon's blood."
Sardonyx, a combination of sard and onyx, has a hardness of 6.5 to 7 on the Mohs scale. While not as hard as ruby, sardonyx is still relatively durable and suitable for everyday wear. Its banded patterns make it an excellent choice for engraved jewelry, as the contrast between the sard and onyx layers enhances the detail of the carvings. Sardonyx has a refractive index of 1.48 to 1.53, which gives it a smooth, glassy luster.
Sapphire, another July birthstone, is also a type of corundum and shares the same hardness as ruby. It has a refractive index of 1.76 to 1.78, similar to ruby, and is available in a range of colors, including blue, yellow, green, and pink. The most valuable sapphires are the deep blue stones from Kashmir, but other colors are also highly prized. Sapphire's durability and brilliance make it a popular choice for engagement rings and other fine jewelry.
Onyx, a form of chalcedony, has a hardness of 6.5 to 7 on the Mohs scale. It is often dyed to enhance its color and is used in a variety of jewelry styles, including rings, bracelets, and earrings. Onyx has a refractive index of 1.48 to 1.53 and is known for its smooth, polished surface and deep black color.
Carnelian, another July birthstone, has a hardness of 6.5 to 7 on the Mohs scale and is a type of chalcedony with a warm, reddish-orange color. It has a refractive index of 1.48 to 1.53 and is often used in beads, pendants, and other jewelry pieces. Carnelian is known for its affordability and durability, making it a popular choice for everyday wear.
The gemological properties of July's birthstones highlight their versatility and appeal. Whether it's the hardness and brilliance of ruby, the banded patterns of sardonyx, or the warm tones of carnelian, these gemstones offer a range of options for jewelry and personal adornment.
