Introduction
The ruby, a member of the corundum family, is one of the most coveted gemstones in the world. Known as the "king of gemstones" in ancient India and revered by royalty and warriors alike, ruby has been cherished for its beauty and symbolic power. Its vibrant red color, derived from trace amounts of chromium, has made it a favorite in jewelry for millennia. As a birthstone for July, ruby is associated with strength, protection, and emotional balance. This article delves into the multifaceted nature of ruby, covering its historical significance, geological formation, gemological properties, metaphysical beliefs, and practical care tips.
History and Lore
Ruby has a long and storied history, with references dating back to ancient civilizations. In Sanskrit, ruby is called "ratnaraj," meaning "king of precious stones," a title that reflects its esteemed status in the ancient world. Ancient Hindus offered rubies to the god Krishna in the hopes of being reincarnated as an emperor, underscoring its association with royalty and divine favor. In ancient India, ruby was believed to possess mystical powers, including the ability to predict misfortune, cure diseases, and bestow invincibility in battle.
The name "ruby" itself originates from the Latin word "ruber," meaning red, a fitting description for a gemstone so deeply associated with the color. In medieval Europe, ruby was thought to bring protection against evil and harm, and it was often worn by nobility and warriors. Burmese warriors believed that wearing rubies made them invincible in battle, highlighting the stone's historical connection with power and strength.
Ruby's allure has also made it a popular choice in jewelry across cultures and eras. From British monarchs to Chinese emperors, ruby has been a symbol of regal authority and prestige. In ancient China, ruby was known as the "jade of fire," a metaphor for its fiery red hue and the warmth it radiated. The Mogok region of Myanmar (formerly Burma) is credited with the discovery of rubies around 2500 BC, making it one of the oldest known sources of this precious gemstone.
In addition to its historical significance, ruby has played a role in various cultural traditions and beliefs. In some cultures, it is believed that ruby can attract good fortune, prosperity, and love. Some early cultures even associated the red color of ruby with the power of life itself, linking it to vitality and energy. These beliefs have endured over time, contributing to ruby's enduring appeal and symbolic value.
Geological Formation and Sources
Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃) with trace amounts of chromium that give it its characteristic red color. The presence of chromium determines the intensity of the red hue, with higher concentrations resulting in deeper, more vibrant colors. The most valuable rubies exhibit a medium to medium-dark red color with little to no purple or orange undertones.
Ruby forms under high-pressure and high-temperature conditions, typically in metamorphic rocks such as marble. The process of metamorphism, which involves the transformation of existing rock through heat and pressure, is crucial for the formation of ruby. Over millions of years, geological activity and tectonic movements create the right conditions for ruby to crystallize. The presence of chromium in the surrounding rock is essential for the development of its red color.
The primary sources of ruby include Myanmar (formerly Burma), which is known for producing some of the finest rubies in the world. The Mogok region in Myanmar has been a renowned source of high-quality ruby for centuries. Other significant sources include Thailand, Cambodia, Vietnam, Sri Lanka, and Madagascar. Each of these regions produces rubies with slightly different characteristics, influenced by the local geological conditions and mineral composition.
Mining ruby is a challenging and labor-intensive process. Due to its formation in metamorphic rocks, ruby is often found in complex geological settings that require specialized techniques for extraction. Traditional mining methods, such as alluvial mining, are still used in some areas, while modern techniques involve advanced geological surveys and drilling. The rarity of high-quality ruby, combined with the difficulty of mining, contributes to its high market value.
Gemological Properties
Ruby is one of the hardest gemstones, ranking 9 on the Mohs scale of mineral hardness. This high hardness makes it resistant to scratches and abrasions, making it an excellent choice for everyday jewelry. However, while ruby is hard, it is also brittle, meaning it can chip or crack if struck with sufficient force. This brittleness is an important consideration when handling and caring for ruby jewelry.
The refractive index of ruby is approximately 1.76 to 1.78, which means it can display a high degree of brilliance and fire when cut properly. The best ruby cuts are those that maximize the stone's natural color and brilliance, such as the round brilliant cut and the emerald cut. The size of the ruby also affects its value, with larger, high-quality stones commanding significantly higher prices.
In terms of clarity, the most valuable rubies are those with minimal inclusions. However, some inclusions are natural and can even be used to identify the origin of the stone. For example, the presence of silk-like inclusions is often associated with Burmese rubies. These inclusions are not considered flaws but rather natural features that can enhance the stone's character and authenticity.
The color of ruby is one of its most defining characteristics. The ideal ruby color is a deep, vibrant red known as "pigeon blood," a term that originated in the 1930s to describe the finest Burmese rubies. Pigeon blood ruby is highly prized for its intense color and is considered one of the most valuable gemstones in the world. Other color variations, such as purplish red or orangy red, are also available but are generally less valuable.
Symbolism and Metaphysical Beliefs
Ruby has long been associated with a range of symbolic meanings and metaphysical properties. In ancient times, it was believed to bring protection against evil and harm, a belief that was particularly popular in medieval Europe. Warriors and nobles often wore ruby as a talisman for strength and invincibility. In some cultures, it was also thought to enhance vitality and energy, making it a popular choice for those seeking physical and emotional strength.
In modern times, ruby continues to be associated with passion, love, and courage. It is often given as a gift to symbolize deep affection and enduring love. Ruby is also the gemstone for the 15th and 40th wedding anniversaries, making it a meaningful choice for celebrating long-term relationships. The vibrant red color of ruby is believed to stimulate the heart and promote emotional balance, making it a popular stone for those seeking to enhance their emotional well-being.
In the realm of astrology, ruby is associated with the zodiac signs of Cancer and Leo. For Cancer, ruby is believed to enhance intuition and emotional stability, while for Leo, it is said to amplify confidence and creativity. These associations reflect the stone's symbolic power and its ability to influence different aspects of a person's life.
Care and Cleaning
Proper care is essential for maintaining the beauty and longevity of ruby jewelry. Despite its high hardness, ruby is still susceptible to damage from harsh chemicals and extreme temperatures. It is important to avoid exposing ruby to substances such as household cleaners, perfumes, and cosmetics, as these can dull its brilliance or cause surface damage.
Cleaning ruby jewelry should be done with care to avoid any potential harm. A simple and effective method involves using lukewarm, soapy water and a soft-bristled toothbrush to gently remove dirt and debris. After cleaning, the jewelry should be rinsed thoroughly and dried with a soft, lint-free cloth. It is important to avoid using ultrasonic cleaners or steam cleaners, as these can cause thermal shock or damage to the gemstone.
Storage is another important aspect of ruby care. To prevent scratches and damage, ruby jewelry should be stored separately from other gemstones and metals. A soft cloth or fabric-lined jewelry box is ideal for keeping ruby protected. It is also advisable to avoid exposing ruby to direct sunlight for extended periods, as this can cause the color to fade over time.
Handling ruby jewelry with care is crucial to prevent accidental damage. It is best to remove ruby jewelry before engaging in activities that involve physical contact or exposure to harsh environments. By following these simple care guidelines, ruby jewelry can remain beautiful and valuable for generations.
