History and Lore
The ruby has been treasured for millennia, with its history intertwined with the mythologies and traditions of various ancient civilizations. The gemstone’s vibrant red color has often been associated with life, vitality, and the heart, making it a symbol of love and courage.
Ancient Reverence
Historical sources reveal that the ruby was highly valued in ancient times. One of the earliest known references comes from the biblical Breastplate of Aaron, described in the Book of Exodus. While the exact identification of the gemstones on the Breastplate is debated, the ruby is often cited as one of the twelve stones, representing the tribe of Judah. This association has contributed to the ruby’s enduring spiritual significance.
In India, the ruby has been regarded as a sacred stone for centuries. Ancient Indian texts, such as the Vedas, mention the ruby as a powerful gemstone that brings prosperity and protection. Indian royalty often adorned themselves with rubies, believing that the stones would safeguard them from harm and bring divine favor.
Similarly, in ancient China, the ruby was believed to promote longevity and good fortune. Chinese emperors wore ruby jewelry to symbolize their strength and authority, reinforcing the gemstone’s association with power and leadership.
European and Middle Eastern Traditions
During the Middle Ages in Europe, the ruby was believed to possess mystical properties. It was thought to be a protective stone that could ward off evil spirits and diseases. Nobles and royalty often wore rubies as talismans, especially during times of war or political instability. The gemstone was also associated with the Sun, and was believed to enhance vitality and courage.
In the 18th and 19th centuries, the ruby gained popularity in European courts. It was used extensively in royal jewelry collections, with many notable pieces passing through generations of monarchs. The ruby’s deep red color and brilliance made it a favorite among aristocrats, who saw it as a symbol of passion and nobility.
Modern Significance
In the 20th century, the ruby was officially recognized as the birthstone for July by the American National Retail Jewelers Association. This designation solidified its role in modern jewelry and gave it a broader cultural significance. Today, the ruby is still considered a symbol of love and commitment, often used in engagement rings and anniversary gifts. It is also associated with the 40th wedding anniversary, where it represents enduring love and devotion.
Despite its ancient origins, the ruby continues to inspire contemporary designers and jewelers. Its timeless appeal lies in its ability to bridge the gap between tradition and modernity, making it a gemstone that resonates across generations.
Geological Formation and Sources
The ruby is a type of corundum, a mineral composed primarily of aluminum oxide (Al₂O₃). What distinguishes the ruby from other corundum varieties—such as sapphire—is the presence of chromium or, less commonly, vanadium, which imparts its characteristic red color. The intensity of the red hue depends on the concentration of these trace elements, with the most valuable rubies exhibiting a deep, vivid red known as “pigeon’s blood.”
Formation Process
Rubies form under intense geological conditions, typically in metamorphic rocks that have been subjected to high pressure and temperature. These conditions cause the aluminum oxide to crystallize in a hexagonal structure. When chromium or vanadium is present in the surrounding environment, it becomes incorporated into the crystal lattice, creating the ruby’s red color.
The formation of rubies often occurs in two primary geological settings: metamorphic rocks and alluvial deposits. Metamorphic rubies are formed when existing rocks are altered by heat and pressure, while alluvial rubies are found in riverbeds and other sedimentary deposits. Alluvial rubies are often more highly prized due to their clarity and purity, as the weathering process tends to remove impurities and inclusions.
Major Sources
Several countries are renowned for producing high-quality rubies, with the most famous being:
Myanmar (Burma): Myanmar is the most well-known source of rubies, particularly for stones with the coveted “pigeon’s blood” color. The Mogok region in northern Myanmar has been a major ruby-producing area for centuries. Rubies from Mogok are highly sought after due to their rich color and exceptional clarity.
Sri Lanka: Sri Lanka is another important source of rubies, though the stones tend to have a slightly different coloration compared to Burmese rubies. Sri Lankan rubies are often lighter in tone and may exhibit a more orange or pinkish hue. However, they are still highly valued for their clarity and brilliance.
Madagascar: In recent decades, Madagascar has emerged as a significant ruby producer. The ruby deposits in this island nation are known for producing large stones with a range of colors, from deep red to pinkish-red. The quality of Madagascan rubies has improved significantly, making them a popular choice for jewelry designers.
Thailand and Cambodia: These countries have historically been important in the ruby trade, particularly as centers for cutting and polishing. While they may not produce as many rubies as Myanmar or Sri Lanka, they play a crucial role in the global ruby market.
Vietnam and Tanzania: These countries also have ruby deposits, though they are not as prominent as the aforementioned sources. Vietnamese rubies are known for their vibrant red color, while Tanzanian rubies tend to have a more pinkish hue.
The rarity of high-quality rubies, combined with their intense color and durability, makes them one of the most valuable gemstones in the world. However, the market is also affected by the discovery of ruby deposits in new regions and advancements in gemstone treatments that enhance their appearance.
Gemological Properties
Understanding the gemological properties of the ruby is essential for both collectors and jewelry buyers. These properties determine the stone’s value, durability, and suitability for various types of jewelry.
Physical and Optical Properties
Hardness: The ruby ranks 9 on the Mohs scale of mineral hardness, making it one of the hardest natural gemstones. This high hardness makes it resistant to scratches and ideal for everyday wear in rings and bracelets.
Color: The most prized rubies exhibit a deep red color, often described as “pigeon’s blood.” This color is caused by the presence of chromium in the corundum crystal structure. Rubies with a pure red color and high transparency are the most valuable.
Luster: Rubies have a vitreous (glassy) luster, which gives them a brilliant and sparkling appearance when polished.
Refractive Index: The refractive index of a ruby typically ranges from 1.76 to 1.78. This high refractive index contributes to the gemstone’s brilliance and fire.
Specific Gravity: The specific gravity of a ruby is between 3.95 and 4.10, which is relatively high compared to other gemstones. This density gives the ruby a solid, substantial feel.
Inclusions and Clarity
Like all natural gemstones, rubies often contain inclusions, which are tiny imperfections or impurities within the crystal structure. These inclusions can vary in type and appearance, from small crystals to feathers or clouds. While some inclusions can detract from the stone’s clarity, others can enhance its uniqueness and character. In fact, certain inclusions are considered characteristic of a ruby and can help distinguish it from synthetic or imitated stones.
High-quality rubies typically have minimal inclusions and excellent clarity. However, completely flawless rubies are extremely rare and command high prices in the market.
Cutting and Shape
Rubies are typically cut into brilliant or step cuts, depending on the desired appearance and the shape of the rough stone. The most common shapes include round, oval, cushion, and princess cuts. The goal of the cut is to maximize the stone’s brilliance and color while maintaining its durability.
In some cases, rubies are cut with a slight convex surface to enhance their fire and sparkle. This technique is particularly effective for larger stones, as it helps to minimize the visibility of inclusions and improve the overall appearance.
