Ruby, the birthstone for the month of July, is a gemstone of extraordinary beauty, symbolism, and historical significance. Known as the “king of gemstones,” ruby is a vibrant red variety of the mineral corundum, and its deep, fiery color has captivated people for centuries. Revered across cultures and eras, ruby is not only a symbol of love and passion but also a stone of power and protection. This article explores the rich history, geological properties, cultural significance, and modern relevance of ruby as the July birthstone. By examining its origins, symbolism, and practical care, we uncover why ruby remains one of the most cherished and enduring gemstones in the world.
History and Lore
The ruby's history is as rich and intense as its color. For centuries, ruby has been a gemstone of the elite, often associated with royalty and divine power. Its name comes from the Latin word ruber, meaning "red," a clear reference to the stone's striking hue. In ancient India, ruby was known as ratnaraj, or "king of precious stones," a title that reflects its rarity, hardness, and beauty. This reverence for ruby was not limited to India; in ancient Burma (modern-day Myanmar), ruby was a royal treasure, and large gemstones were considered the exclusive property of the Burmese Crown.
Historical texts and artifacts suggest that ruby has been prized for thousands of years. One notable reference appears in the 19th-century French book Lapidaire en Vers, which mentions that, "by Christ’s command the ruby was placed on Aaron’s neck, the ruby, called the lord of gems." This biblical reference, though debated in authenticity, underscores ruby's association with power and divine favor. In the Roman world, Pliny the Elder, a military commander and philosopher, believed that rubies were of igneous origin—formed by lightning or "fire from heaven." This mythological explanation contributed to ruby's mystique, reinforcing its perceived magical properties.
In medieval Europe, ruby was believed to possess protective qualities. Some thought that the stone could predict danger or misfortune, while others claimed it could cure inflammatory diseases and calm anger. In Burmese culture, warriors wore ruby amulets in battle, believing that the stone would make them invincible. These beliefs, rooted in a blend of superstition and reverence, contributed to ruby's status as a powerful and sacred gemstone.
By the 20th century, ruby had been firmly established as the official July birthstone. Its fiery red color, symbolic of love and passion, made it a fitting representation of the summer month. The association of ruby with July is also supported by its historical use in jewelry and its connection to the summer season. As the hottest month of the year, July’s energy is mirrored by the intense red hue of ruby, a color long associated with warmth, vitality, and life.
Geological Formation and Sources
Ruby is a mineral form of corundum, a crystalline form of aluminum oxide (Al₂O₃). What distinguishes ruby from other corundum varieties—such as sapphire—is the presence of trace amounts of the element chromium. Chromium gives ruby its characteristic red color, with the most valuable stones displaying a deep red with a slight purplish tint, known in the trade as "pigeon’s blood." The more chromium present, the more intense the red color becomes. This chemical composition also contributes to ruby's exceptional hardness and durability.
Ruby forms in metamorphic rocks, particularly in areas where limestone or marl has been subjected to high pressure and temperature. These geological conditions allow the aluminum and oxygen atoms in corundum to crystallize, with chromium acting as a trace element to produce the red color. The formation process can take millions of years, making ruby a truly rare and valuable gemstone.
Historically, ruby has been mined in several key locations around the world. Burma (Myanmar) has long been the most famous source of high-quality ruby. The Mogok Stone Tract in Myanmar has produced some of the finest "pigeon’s blood" rubies, which are highly sought after in the gem trade. Other notable ruby-producing countries include Thailand, Sri Lanka, Afghanistan, and more recently, Mozambique. Each region produces rubies with slightly different color tones and inclusions, which can help gemologists identify the origin of a stone.
In modern times, ruby is still primarily sourced from these traditional locations, though new deposits have been discovered in places such as Madagascar and Vietnam. These new sources have expanded the ruby market, making the gemstone more accessible to consumers while maintaining its status as a precious and valuable stone.
Gemological Properties
Ruby's gemological properties are as impressive as its historical significance. As a corundum variety, ruby ranks 9 on the Mohs Hardness Scale, making it one of the hardest and most durable gemstones available. This high level of hardness allows ruby to resist scratches and wear, making it suitable for daily wear in jewelry such as rings, necklaces, and bracelets. Despite its hardness, ruby can still be damaged by sudden impacts or exposure to extreme temperatures, so proper care is essential.
The color of ruby is its most defining feature. The presence of chromium in the crystal structure imparts a deep red hue, which can vary in intensity and tone depending on the concentration of the element. The most valuable rubies display a "pigeon’s blood" color—named after the deep red of a pigeon’s chest—characterized by a rich red with a subtle purple undertone. This color is highly prized in the gem trade and commands some of the highest prices in the world of fine jewelry.
Clarity in ruby can vary, as the stone often contains natural inclusions. These inclusions, known as "silk," can enhance the stone's beauty by giving it a velvety appearance. While some inclusions may reduce a ruby's clarity grade, they are also indicators of a natural, untreated gemstone. High-quality rubies are typically eye-clean, meaning that inclusions are not visible to the naked eye.
Ruby is also known for its excellent luster and refractive properties. When cut properly, ruby can display a brilliant, fiery luster that enhances its natural beauty. The most common cut for ruby is the emerald cut, which emphasizes the stone's clarity and color. Other popular cuts include round, oval, and cushion cuts, each of which can showcase ruby's unique characteristics.
In terms of size, ruby can be found in a range of carat weights, from small gemstones suitable for everyday jewelry to large, rare specimens that can weigh several carats. The larger the ruby, the rarer it becomes, which significantly increases its value. High-quality, large rubies are extremely rare and can fetch millions of dollars at auction.
Symbolism and Metaphysical Beliefs
Throughout history, ruby has been associated with a wide range of symbolic meanings and metaphysical properties. In many cultures, ruby is seen as a symbol of love, passion, and vitality. Its deep red color is often linked to the heart and life force, making it a popular gemstone for romantic jewelry and sentimental gifts. In ancient India, ruby was believed to embody the life force of blood, representing power and youthful energy. This symbolism made ruby a popular gemstone in Indian jewelry, where it was worn not only for its beauty but also for its perceived ability to enhance strength and vitality.
In medieval Europe, ruby was thought to have protective properties. Some believed that the stone could predict danger or misfortune, serving as a kind of spiritual alarm. Others claimed that ruby could calm anger and soothe inflammation, making it a valuable gemstone for healing and emotional balance. These beliefs contributed to ruby's use in talismans and amulets, particularly among the wealthy and powerful.
In Burmese culture, ruby was considered a stone of invincibility. Warriors wore ruby amulets in battle, believing that the gemstone would protect them and give them an edge in combat. This belief in ruby's protective power extended beyond the battlefield, with the stone also being used in everyday life to ward off negative energy and promote courage.
Modern metaphysical beliefs also attribute ruby with a range of positive properties. It is often considered a stone of passion and motivation, helping individuals to harness their inner strength and pursue their goals with confidence. Ruby is also associated with grounding and emotional stability, making it a popular choice for those seeking to balance their emotions and stay centered. In some traditions, ruby is believed to enhance creativity and inspiration, making it a valuable gemstone for artists, writers, and visionaries.
Care and Cleaning
Due to its exceptional hardness and durability, ruby is a gemstone that can be worn daily without significant risk of damage. However, proper care is essential to maintain the gemstone's beauty and longevity. Ruby can be cleaned using warm, soapy water and a soft cloth or brush. It is important to avoid using harsh chemicals or ultrasonic cleaners, as these can potentially damage the gemstone or its setting.
When handling ruby jewelry, it is advisable to avoid exposing the stone to extreme temperatures or sudden temperature changes. High heat can cause the gemstone to fracture, while rapid temperature shifts can lead to internal stress and potential damage. Additionally, ruby should be stored separately from other gemstones to prevent scratches, as even the hardest gemstones can cause minor abrasions.
For ruby jewelry that is part of a valuable collection or heirloom piece, it is recommended to have the gemstone professionally cleaned and inspected by a qualified gemologist or jeweler. This can help identify any potential issues with the stone or its setting and ensure that the gemstone remains in optimal condition for years to come.
