History and Lore
Rubies have been revered across cultures and centuries, often associated with power, passion, and protection. The earliest known sources of ruby were in Myanmar (formerly Burma), where the gemstone has been mined for over 600 years. The name "ruby" comes from the Latin word "ruber," meaning "red," a color that has long symbolized vitality, love, and courage. In ancient times, rubies were believed to possess magical properties and were worn as talismans to ward off illness, enhance fertility, and bring good fortune.
The gemstone's association with royalty is particularly notable. Throughout history, rubies have been a favorite among monarchs and aristocrats. The deep red hue of ruby was considered a symbol of nobility and divine favor. In medieval Europe, it was believed that rubies could protect their owners from harm and even prevent poisoning. This belief was so widespread that some rulers carried rubies in their pockets or fastened them to their clothing as a protective measure.
Ruby also holds a prominent place in religious and cultural traditions. In Hindu mythology, ruby is associated with the Sun god, Surya, and was thought to bring energy and vitality. In Chinese culture, ruby symbolizes good luck and prosperity, and it was often used in ceremonial objects and royal jewelry. The gemstone's fiery red color was also linked to the life force, or "chi," in traditional Chinese medicine.
In the modern era, ruby has retained its allure and prestige. It was designated as the official birthstone for July in the 20th century, and its popularity has only grown with time. Today, ruby is not only a symbol of love and passion but also a stunning centerpiece in fine jewelry, from engagement rings to statement necklaces.
Geological Formation and Sources
Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). What distinguishes ruby from other corundum gems is the presence of trace amounts of chromium (Cr³⁺), which imparts its characteristic red color. The intensity of the red hue can vary depending on the concentration of chromium and the presence of other trace elements. The most highly prized rubies exhibit a vibrant, deep red color known as "pigeon's blood," a term often used to describe the finest Burmese rubies.
Rubies are formed under intense heat and pressure deep within the Earth's crust, typically in metamorphic rock environments. These conditions cause the aluminum oxide to crystallize into corundum, and the presence of chromium gives the gemstone its red color. Over time, geological forces bring these gems closer to the surface, where they can be extracted through mining.
The primary sources of ruby include Myanmar, where the gemstone has been historically most famous, as well as Thailand, Vietnam, Cambodia, and other regions. Each source produces rubies with unique characteristics. For example, Burmese rubies are known for their intense red color and excellent clarity, while Thai rubies often have a slightly more pinkish hue. In recent decades, new ruby deposits have been discovered in countries like Mozambique, Madagascar, and Afghanistan, expanding the global supply of this precious gemstone.
Mining ruby is a complex and often labor-intensive process. Traditional methods involve manual extraction from alluvial deposits or hard rock mining. Due to the gemstone's value, ruby mining has also been associated with environmental and ethical concerns. As a result, there is a growing emphasis on responsible sourcing and sustainable mining practices to ensure that ruby remains a symbol of beauty and integrity for future generations.
Gemological Properties
Ruby's beauty and durability are due to its unique gemological properties. As a corundum, ruby has a hardness of 9 on the Mohs scale, making it one of the hardest gemstones, second only to diamond. This high hardness allows ruby to be used in a wide range of jewelry applications, including rings, bracelets, and earrings, where it can withstand daily wear with proper care.
The refractive index of ruby ranges from 1.76 to 1.78, which contributes to its brilliance and fire. When cut and polished, ruby exhibits a luster that is described as vitreous or glassy. The best-cut rubies display excellent light performance, with a balance of brilliance, dispersion, and fire that enhances their visual appeal.
In terms of color, ruby is most highly valued for its deep red to purplish-red hues. The "pigeon's blood" color, which is considered the most desirable, is characterized by a vivid red with a slight blue undertone. This color is typically found in the finest Burmese rubies. The presence of inclusions, or internal characteristics, is also an important factor in ruby's appearance. While some inclusions can affect clarity, they are often seen as a natural part of the gemstone's identity and can even enhance its value when they are small and not visible to the naked eye.
Ruby can also be found in a range of sizes, from small melee stones used in pave settings to large, statement pieces weighing several carats. The most valuable rubies are typically those that are large in size and exhibit excellent color and clarity.
Symbolism and Metaphysical Beliefs
Throughout history, ruby has been associated with a wide range of symbolic meanings and metaphysical properties. In many cultures, ruby has been regarded as a stone of love, passion, and vitality. Its deep red color has long been linked to the heart and blood, making it a powerful symbol of life and energy. In ancient times, ruby was believed to enhance courage, protect against danger, and promote good fortune.
One of the most enduring legends about ruby comes from the Roman naturalist Pliny the Elder, who wrote that the gemstone was "a stone that never fails in its protective qualities." He described ruby as a stone that could absorb the negative energy of poisons and prevent them from causing harm. This belief was so widespread that some rulers carried rubies in their pockets or fastened them to their clothing as a protective measure.
In modern times, ruby continues to be associated with love and passion. It is often used in romantic jewelry, including engagement rings and anniversary gifts, to symbolize enduring love and devotion. Ruby is also believed to promote emotional stability and help individuals express their feelings more openly.
Metaphysically, ruby is considered a stone of the heart chakra, which is associated with love, compassion, and emotional healing. It is believed to stimulate the heart chakra, enhancing feelings of love and reducing fear and anxiety. Ruby is also thought to enhance vitality and energy, making it a popular choice for those seeking to boost their physical and emotional well-being.
In the realm of crystal healing, ruby is used to treat a variety of ailments, including heart conditions, circulatory problems, and hormonal imbalances. It is believed to stimulate the blood and improve circulation, which can help with conditions such as anemia and fatigue. Ruby is also thought to enhance the immune system and promote a sense of vitality and strength.
Care and Cleaning
Due to its high hardness and durability, ruby is a relatively easy gemstone to care for. However, to maintain its beauty and longevity, it is important to follow proper care and cleaning guidelines. Ruby can be cleaned using a soft brush, warm water, and mild dish soap. Gently scrub the gemstone to remove any dirt or debris, then rinse it thoroughly and dry it with a soft cloth.
Avoid using harsh chemicals or ultrasonic cleaners, as these can potentially damage the gemstone or any surrounding settings. Ruby is sensitive to sudden temperature changes, so it is best to avoid exposing it to extreme heat or cold. When storing ruby jewelry, keep it in a separate compartment to prevent scratches from other gemstones or metals.
If your ruby jewelry requires professional cleaning or repair, it is best to take it to a reputable jeweler who specializes in gemstone care. They can provide expert advice on how to maintain the gemstone's appearance and ensure that it remains in excellent condition for years to come.
