It is intended for gemstone enthusiasts, jewelry buyers, and students of gemology who seek to understand the ruby not only as a decorative element in jewelry but as a significant natural phenomenon and cultural icon.
History and Lore
The ruby has long been a symbol of power, protection, and divine favor. Ancient civilizations, including the Greeks, Romans, and Hindus, believed that rubies possessed mystical properties. In India, the ruby was known as the "king of gems" and was believed to bring good fortune, wisdom, and protection from harm. The belief in the ruby's protective qualities was particularly strong in the Middle Ages, when it was often worn as a talisman against disease and misfortune.
The ruby's association with royalty and nobility is well-documented. In the 16th century, the famed French naturalist and mineralogist, Bernard Palissy, described the ruby as a stone of "inestimable value," and it was commonly used in royal regalia and jewelry. The ruby's deep red color, which is attributed to the presence of chromium or vanadium in its crystal structure, was thought to mirror the blood of Christ and thus symbolize life, vitality, and the divine. This symbolism made the ruby a popular choice for religious and ceremonial jewelry.
In the East, particularly in Burma (modern-day Myanmar), rubies were considered sacred and were often set in religious artifacts and imperial regalia. The "Burmese Ruby," a term used to describe the finest quality rubies from this region, was highly prized for its intense color and clarity. The ruby's journey from the mines of Burma to the royal courts of Europe and Asia is a testament to its enduring allure and cultural significance.
Geological Formation and Sources
Rubies are a variety of the mineral corundum (Al₂O₃), which is composed of aluminum oxide. The presence of trace amounts of chromium or vanadium gives rubies their characteristic red color. The most prized rubies exhibit a deep, vivid red with a slight purplish or orange secondary hue, a color known in the trade as "pigeon's blood."
The formation of rubies occurs under high-pressure and high-temperature conditions deep within the Earth's crust, typically in metamorphic rocks such as marble and in igneous rocks such as basalt. Over millions of years, these conditions cause the aluminum oxide to crystallize into corundum, and the presence of chromium impurities results in the formation of ruby. The quality and color of a ruby are influenced by factors such as the concentration of chromium, the presence of other trace elements, and the geological history of the deposit.
Myanmar (formerly Burma) is historically the most famous source of rubies, particularly those found in the Mogok region. These rubies are renowned for their vibrant red color and exceptional quality. Other significant sources include Thailand, Sri Lanka, Afghanistan, and more recently, Madagascar and Tanzania. Each of these locations produces rubies with distinct characteristics, influenced by their geological settings and the specific conditions under which the gems formed.
The ruby's rarity, combined with the specific geological conditions required for its formation, contributes to its high value in the gemstone market. High-quality rubies are among the most expensive gemstones in the world, with prices often exceeding those of diamonds, especially for stones of exceptional color and clarity.
Gemological Properties
Rubies are among the hardest gemstones, second only to diamonds on the Mohs scale of mineral hardness. With a hardness of 9, rubies are durable enough for use in a wide range of jewelry, including rings, earrings, and pendants. This hardness also makes rubies resistant to scratches and abrasions, which is an important consideration for their care and maintenance.
In addition to hardness, rubies are valued for their refractive index, which measures how light is bent as it passes through the gemstone. Rubies have a refractive index of approximately 1.76–1.78, which contributes to their brilliance and fire. The interplay of light within the ruby enhances its color and makes it appear more vibrant when properly cut.
The cut of a ruby is crucial in maximizing its beauty. Rubies are typically cut in the form of brilliant or step cuts, depending on the desired effect. A well-cut ruby will display excellent color saturation, clarity, and light return, making it a visually stunning gemstone. The weight of a ruby is measured in carats, and larger, high-quality rubies are extremely rare and valuable.
Clarity is another important factor in evaluating rubies. While most rubies contain inclusions—small internal or external characteristics that can affect their appearance and value—these inclusions are often considered part of the gem's natural character. In fact, the presence of certain inclusions can be used to determine the origin of a ruby. For example, silk-like inclusions composed of fine rutile needles are commonly found in Burmese rubies and are considered desirable.
Symbolism and Metaphysical Beliefs
Throughout history, rubies have been associated with a wide range of symbolic meanings and metaphysical properties. In ancient times, the ruby was believed to possess protective and healing properties. It was thought to ward off evil spirits, prevent illness, and promote good fortune. In some cultures, rubies were also used in love and fertility rituals, as the gemstone was associated with passion and vitality.
In the realm of metaphysical beliefs, rubies are often considered a stone of courage, strength, and motivation. They are said to enhance confidence, stimulate ambition, and encourage one to pursue their goals with passion and determination. Rubies are also believed to promote a sense of emotional balance and to help individuals overcome fear and anxiety.
In modern times, the ruby continues to be associated with love and romance. As the birthstone for July, it is often given as a gift to symbolize deep affection and enduring love. The ruby's deep red color is often interpreted as a symbol of the heart and the emotions it represents. This symbolism has made the ruby a popular choice for engagement rings, anniversary gifts, and other romantic jewelry.
The ruby's metaphysical properties are also linked to the root chakra, which is associated with grounding, stability, and physical vitality. It is believed that wearing a ruby can help to activate this chakra and promote a sense of security and well-being. Additionally, rubies are thought to enhance one's ability to connect with their inner power and to take action on their desires.
While the metaphysical properties of the ruby are not scientifically validated, they reflect the deep cultural and historical significance of the gemstone. These beliefs have contributed to the ruby's enduring popularity and its continued use in jewelry and spiritual practices.
Care and Cleaning
Due to its high hardness and durability, the ruby is a relatively easy gemstone to care for. However, there are several considerations that should be taken into account to ensure that ruby jewelry remains in good condition over time.
One of the most important aspects of ruby care is avoiding exposure to harsh chemicals. While rubies are resistant to most household chemicals, prolonged exposure to substances such as bleach, ammonia, and acids can cause damage to the gemstone or its setting. It is recommended to remove ruby jewelry before using cleaning products or swimming in chlorinated water.
Another important consideration is the use of ultrasonic and steam cleaners. While these methods are generally safe for most gemstones, they may not be suitable for rubies with inclusions or coatings. In particular, rubies that have been treated with glass or other materials to enhance their appearance may be damaged by ultrasonic cleaning. It is best to consult a professional jeweler before using these methods on ruby jewelry.
When it comes to everyday care, it is advisable to store ruby jewelry separately from other gemstones to prevent scratches. Rubies are hard enough to scratch softer gemstones such as emeralds and sapphires, so they should be stored in a soft cloth or a separate compartment to avoid contact. Regular cleaning with a soft cloth and mild soap can help maintain the gemstone's luster and appearance.
For more thorough cleaning, a professional jeweler can perform a deep clean using specialized tools and solutions. This is particularly recommended for ruby jewelry that is worn frequently or for pieces that have not been cleaned in a while. A professional cleaning can help remove dirt, oils, and other residues that may dull the gemstone's appearance.
