History and Lore
The historical narrative of ruby is as ancient and multifaceted as the gemstone itself. For thousands of years, rubies have fascinated humanity, adorning royalty, warriors, and spiritual leaders across the globe. In ancient India, ruby was revered as the “king of precious stones,” a designation that highlights its perceived superiority in terms of rarity, hardness, and mystical power. Ancient Hindu beliefs held that rubies could predict misfortune or danger, and some cultures even attributed the ability to cure inflammatory diseases and soothe anger to this fiery gem. This association with the life force of blood further reinforced its significance as a symbol of vitality and strength.
Burmese warriors, in particular, held ruby in the highest esteem, believing it made them invincible in battle. The gemstone’s color, evocative of blood and fire, naturally linked it to courage, valor, and leadership. This martial association is a recurring theme in ruby’s history, where it was often integrated into armor and weaponry as a talisman for protection and strength. In medieval Europe, rubies were believed to bring health, wealth, and wisdom. The deep red hues made rubies legendary among gemstones, leading to their integration into the most coveted jewels, crowns, and ceremonial regalia around the world.
Beyond its martial and regal associations, ruby has also been deeply connected to romantic love and passion in Western cultures. The rich red shade of ruby has led to centuries of association with romance, love, and the heart. In many traditions, rubies are given as tokens of passionate affection or as symbols in engagement and anniversary jewelry. The color is thought to ignite passion and nurture strong bonds between loved ones. This romantic symbolism is so potent that ruby is often used in jewelry to symbolize enduring love and devotion, making it a popular choice for engagement rings and other pieces meant to convey deep emotional commitment.
The journey of ruby to its status as a modern birthstone is rooted in these ancient traditions. The concept of birthstones, as we know it today, evolved from various historical and cultural practices, including the breastplates of ancient priests and the twelve stones of the New Jerusalem. The modern list of birthstones was standardized in 1912 by the American National Association of Jewelers, with ruby officially designated for the month of July. This designation solidified ruby’s role as a unique symbol for individuals born in this month, who are believed to enjoy the gemstone’s associated qualities of protection, love, and happiness. The ruby’s strong symbolism has also made it a favored anniversary stone, particularly for the 15th and 40th wedding anniversaries, expressing enduring love and commitment.
Geological Formation and Sources
Rubies belong to the corundum mineral family, the same family as sapphires, but derive their red color from traces of chromium. The formation of ruby is a geological marvel, requiring specific conditions of high temperature and pressure. Corundum forms in metamorphic rocks, typically in marble or in mafic and ultramafic rocks. The presence of chromium is the critical factor that imparts the red color; if no chromium is present, the corundum is classified as a sapphire. The intensity and hue of the red are directly related to the concentration of chromium and other trace elements like iron and titanium, which can influence the color’s saturation and tone.
The primary sources of high-quality rubies are geographically concentrated in a few key regions. Historically, the most prized rubies have come from Myanmar (formerly Burma), specifically from the Mogok region. Burmese rubies are renowned for their vivid, “pigeon’s blood” red color, a term used to describe the most desirable hue—a deep, vivid red with a slight bluish undertone. The geological conditions in Myanmar have produced rubies of exceptional color and clarity, making them highly sought after in the gem market.
Other significant ruby sources include Sri Lanka, Thailand, Madagascar, and Mozambique. Sri Lankan rubies, while often lighter in color than their Burmese counterparts, are prized for their clarity and brilliance. Thai rubies, historically sourced from the Chanthaburi and Trat provinces, often exhibit a darker, more brownish-red hue due to higher iron content. Recent discoveries in Madagascar and Mozambique have added to the global supply, offering rubies with varying color characteristics that can be comparable to traditional sources. The geographic distribution of ruby deposits is limited, contributing to the gemstone’s rarity and high value.
The mining of ruby is often a labor-intensive process, frequently involving small-scale artisanal operations, particularly in regions like Myanmar and Madagascar. These operations can be challenging due to the remote locations and difficult terrain. The ethical sourcing of ruby has become an increasingly important consideration in the modern gem trade, with a growing emphasis on transparency and fair labor practices. Consumers and jewelers alike are encouraged to seek out rubies from reputable suppliers who can provide information on the gem’s origin and the conditions under which it was mined.
Gemological Properties
The gemological properties of ruby are what make it one of the most durable and visually stunning natural minerals. Its key characteristics are defined by its chemical composition, crystal structure, and physical attributes.
Chemical Composition and Crystal Structure: Ruby is a variety of the mineral corundum, with a chemical formula of Al₂O₃ (aluminum oxide). The red color is caused by trace amounts of chromium (Cr³⁺) substituting for aluminum in the crystal lattice. The presence of chromium is essential; without it, the gemstone would be a sapphire. Ruby crystallizes in the trigonal system, forming hexagonal prismatic crystals. This crystal structure contributes to its hardness and durability.
Hardness and Durability: On the Mohs hardness scale, ruby ranks 9, making it one of the hardest natural minerals, second only to diamond. This exceptional hardness means ruby is highly resistant to scratching and abrasion, making it an excellent choice for jewelry that is worn daily, such as rings and bracelets. However, despite its hardness, ruby can still be subject to chipping or breaking if struck with sufficient force, particularly along its cleavage planes. While corundum has no distinct cleavage, it has parting in some directions, which can be a point of weakness.
Color: The color of ruby is its most defining feature. The most desirable rubies display a deep, vivid red, often referred to as “pigeon’s blood red.” This term, traditionally associated with Burmese rubies, describes a pure, vibrant red with a slight bluish undertone. The color is caused by chromium, while iron and titanium can influence the hue, adding brownish or purplish tones. The saturation and tone of the color are critical factors in determining a ruby’s value, with the most prized stones exhibiting intense, even coloration.
Clarity and Luster: While inclusions are common in natural rubies, high-quality stones are relatively clear with minimal visible imperfections. Inclusions can provide information about the gem’s origin and natural formation. For example, silk inclusions (fine needles of rutile) are often seen in rubies from certain localities and can enhance the stone’s color through light scattering. A fine-quality ruby exhibits a bright, glassy, and vitreous luster, which contributes to its brilliance and appeal.
Cut and Carat Weight: Rubies are cut into various shapes to maximize their color and minimize the visibility of inclusions. Common cuts include oval, cushion, and round brilliant, with faceted styles that enhance light return. The carat weight of a ruby is a significant factor in its value, with larger stones being exponentially rarer and more valuable. However, color is often a more critical determinant of value than size; a smaller stone with exceptional color can be more valuable than a larger, paler one.
