This article will examine the geological properties, historical use, and cultural symbolism of these stones, while also providing practical advice for caring for ruby and carnelian jewelry.
History and Lore
The ruby and carnelian have been cherished for thousands of years, each with its own rich historical narrative. These gemstones were highly valued in ancient civilizations and have been used in royal regalia, sacred objects, and personal adornment.
The ruby, often referred to as the "King of Gemstones," has been treasured since antiquity. Ancient cultures, including the Greeks, Romans, and Chinese, believed in its protective and healing properties. In India, ruby was associated with the sun and was believed to bring vitality and prosperity. It was also a symbol of passion, courage, and divine power. Historical records show that ruby was used in royal crowns and scepters, often as a symbol of nobility and strength.
Carnelian, on the other hand, was a popular stone in ancient Egypt, Greece, and Rome. The Egyptians believed that carnelian could provide protection and was often used in amulets and seals. In ancient Greece and Rome, it was associated with vitality and was believed to enhance energy and courage. Carnelian was also used in signet rings, which were used to stamp wax seals on documents, a practice that dates back to the ancient world.
The association of ruby and carnelian with July as birthstones is a more modern concept, though both stones have been recognized for their symbolic significance for centuries. The tradition of birthstones can be traced back to the biblical Breastplate of Aaron, which is mentioned in the Book of Exodus. This sacred artifact contained twelve gemstones, each representing one of the twelve tribes of Israel. While the exact identities of these stones remain debated, the practice of associating gemstones with specific months and their symbolic meanings has endured.
In the modern era, the American National Association of Jewelers (now the Jewelers of America) standardized the list of birthstones in the early 20th century. Since then, ruby and carnelian have been recognized as the official birthstones for July. This dual designation is relatively rare and highlights the unique connection between the two gemstones and the month of July.
Geological Formation and Sources
Understanding the geological properties of ruby and carnelian is essential for appreciating their beauty and durability. Both gemstones are formed through distinct geological processes and are found in various parts of the world.
The ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). What distinguishes ruby from other corundum varieties is the presence of trace amounts of chromium, which gives it its characteristic red color. The most valuable rubies are those that display a deep, intense red known as "pigeon's blood." These stones are typically found in metamorphic rocks, where they form under high-pressure and high-temperature conditions over millions of years.
The primary sources of ruby include Myanmar (Burma), Thailand, Sri Lanka, and Madagascar. Myanmar is particularly famous for producing high-quality rubies, especially those from the Mogok region. These rubies are renowned for their rich color and clarity. The geological conditions in these regions create the perfect environment for ruby formation, with the stones often found in alluvial deposits where they have been naturally concentrated by water over time.
Carnelian, in contrast, is a type of chalcedony, which is a microcrystalline variety of quartz. It is composed of silicon dioxide (SiO₂) and owes its color to iron impurities. Carnelian typically forms in sedimentary rocks, where it is often found in nodules or veins. It is also commonly found in volcanic rocks, where it can be formed through the interaction of silica-rich fluids with iron-bearing minerals.
The primary sources of carnelian include India, Brazil, Uruguay, and the United States. India has been a major source of carnelian for centuries, with the stone being mined in regions such as Rajasthan and Madhya Pradesh. Brazil and Uruguay are also known for producing high-quality carnelian, which is often used in jewelry and decorative objects. The availability of carnelian in these regions has made it a popular and accessible gemstone, contributing to its widespread use in jewelry design.
Both ruby and carnelian are relatively durable gemstones, though they have different hardness levels on the Mohs scale. Ruby has a hardness of 9, making it one of the hardest gemstones after diamond. This durability makes it suitable for use in everyday jewelry, including earrings. Carnelian, with a hardness of 6.5 to 7, is also durable but less so than ruby. While it can be used in earrings, it requires more careful handling to avoid scratches and damage.
The availability of these gemstones in various parts of the world has contributed to their popularity in jewelry design. Ruby and carnelian are often used in earrings due to their vibrant colors and durability, making them ideal for both everyday wear and special occasions.
Gemological Properties
To fully appreciate ruby and carnelian, it is essential to understand their gemological properties, including their chemical composition, hardness, refractive index, and color characteristics. These properties not only determine the appearance of the gemstones but also influence their use in jewelry.
Ruby, as a variety of corundum, has a chemical composition of aluminum oxide (Al₂O₃) with trace amounts of chromium responsible for its red color. Its hardness on the Mohs scale is 9, making it one of the hardest gemstones and highly resistant to scratches. This durability makes it an excellent choice for use in jewelry, including earrings, where it can withstand daily wear. The refractive index of ruby ranges from 1.76 to 1.78, which contributes to its brilliance and fire. The most desirable rubies display a deep red color with slight blue undertones, a quality known as "pigeon's blood." These stones are often found in alluvial deposits and are cut in a variety of shapes, including oval, round, and emerald cuts.
Carnelian, a type of chalcedony, has a chemical composition of silicon dioxide (SiO₂) with iron impurities responsible for its warm orange-red color. Its hardness on the Mohs scale is 6.5 to 7, making it less durable than ruby but still suitable for use in jewelry. Carnelian has a refractive index of 1.53 to 1.54, which gives it a subtle luster. The color of carnelian can vary from a pale yellowish orange to a deep red, depending on the concentration of iron. It is often found in sedimentary and volcanic rocks and is cut in various shapes, including cabochons, ovals, and rounds.
Both ruby and carnelian are popular choices for use in earrings due to their vibrant colors and durability. Ruby’s intense red color and high hardness make it a luxurious and long-lasting option, while carnelian’s warm tones and moderate hardness make it a versatile and accessible gemstone. The availability of these gemstones in different sizes and shapes allows for a wide range of jewelry designs, from simple stud earrings to more intricate bar and hoop designs.
