History and Lore
The history of the ruby is steeped in myth, royalty, and a reverence for its fiery color, which has long been associated with the life force of blood. Its name is derived from the Latin word ruber, meaning "red," a direct reference to its most defining characteristic. For millennia, this gemstone has been more than mere ornamentation; it has been a talisman of power, a symbol of love, and even a tool for divination.
In ancient India, the ruby was esteemed so highly that it was dubbed the "king of precious stones." Its rarity, combined with a hardness second only to the diamond and a beauty that seemed to possess mystical powers, cemented its regal status. The stone was deeply connected to the concept of life force and blood, symbolizing power and youthful energy in Indian jewelry. Ancient beliefs attributed to the ruby the ability to predict misfortune or danger and to cure inflammatory diseases and soothe anger. This connection to vitality and protection was not limited to the Indian subcontinent.
Burmese warriors held a particularly potent belief in the ruby's power. They were convinced that embedding a ruby into their flesh would render them invincible in battle, a testament to the stone's perceived strength and protective qualities. This belief underscores the historical perception of the ruby as a gem of courage and power, a theme that resonates through its modern association with the bold sign of Leo.
The journey of the ruby from a mystical talisman to a formal birthstone is a more recent development, rooted in the 19th-century tradition of modern birthstone lists. While the specific assignment of ruby to July is a convention of this era, the stone's connection to the summer month is ancient and intuitive. The bond between July, the hottest month of the summer season, and the fiery red ruby dates back to antiquity. In ancient times, people chose stones to match a month’s spirit, and the ruby, with its color mirroring the heat of July days, was a natural and perfect fit. Its selection as July's birthstone formalized a long-standing cultural association between the gem's vibrant energy and the peak of summer.
Geological Formation and Sources
The ruby is a variety of the mineral corundum, which is crystalline aluminum oxide (Al₂O₃). Its red color is the result of trace amounts of chromium replacing some of the aluminum atoms in the crystal lattice. The more chromium present, the more intense the red hue. This specific chemical composition must occur under precise geological conditions: high pressure and temperature, typically within metamorphic rocks.
The formation of ruby is a rare event in the geological process, which contributes significantly to its value and scarcity. The chromium needed for its color is not abundant in most rock-forming environments, and the conditions must be just right to produce gem-quality crystals of sufficient size and clarity.
The most historically significant and renowned source of rubies is Myanmar (formerly Burma), particularly the Mogok region. Rubies from this area are celebrated for their exceptional color and quality, often described as a "pigeon's blood" red—a deep, vibrant red with a slight bluish hue. This specific origin is so associated with top-tier quality that "Burmese ruby" is often used as a benchmark for the finest color in the trade.
Other notable sources of rubies include Thailand, which is another major commercial producer. However, rubies from Thailand often exhibit a darker, more brownish-red color compared to the vibrant reds of Myanmar. Other sources around the world, such as those in Afghanistan, Vietnam, and parts of Africa, also contribute to the global supply, each with slight variations in color and quality influenced by their specific geological conditions.
Gemological Properties
The ruby is distinguished by a set of gemological properties that make it both beautiful and exceptionally durable, suitable for a wide range of jewelry applications.
Color: The defining characteristic of the ruby is its intense red color. The ideal ruby color is a pure, vivid red with even saturation, graded based on hue, tone, and saturation. The most prized variety exhibits a deep red with a hint of purple, known in the trade as "pigeon's blood." Other color variations include pinkish reds, which are generally less valuable than the deeper reds, and brownish reds, which are less desirable and typically command lower market values. The influence of origin is notable; for instance, Burmese rubies are renowned for their superior color, while Thai rubies often present a darker hue.
Hardness and Durability: The ruby ranks an impressive 9 out of 10 on the Mohs Hardness Scale, making it second only to diamond in terms of hardness. This remarkable strength means ruby jewelry can handle daily wear without showing signs of damage, as it resists scratching and common wear and tear. This exceptional hardness makes ruby rings, in particular, perfect for daily wear, and its durability ensures it can stand the test of time as an heirloom piece.
Chemical Composition: As a variety of corundum, ruby's chemical formula is aluminum oxide (Al₂O₃), with chromium as the trace element responsible for its red color.

Symbolism and Metaphysical Beliefs
Beyond its physical attributes, the ruby carries a profound weight of symbolism and metaphysical belief. Its color, evocative of passion and life, has made it a powerful emblem across cultures.
Love and Passion: The ruby's deep red is universally recognized as the color of love and passion. This association is so strong that it is often considered a gemstone for romantic milestones, such as anniversaries. Its fiery energy is said to ignite feelings of love and desire, making it a popular choice for engagement rings and romantic jewelry.
Protection and Power: Historically, the ruby has been a talisman for protection. The belief that it could ward off danger and misfortune is ancient, as is the conviction that it could enhance courage and vitality. The Burmese warriors' faith in its invincibility is a direct example of this symbolism. In modern metaphysical beliefs, the ruby is still considered a stone of courage, power, and leadership, aligning perfectly with the bold and creative energy of the zodiac sign Leo.
Prosperity and Vitality: The ruby is also linked to prosperity and vitality. Its connection to the life force, or blood, makes it a symbol of energy, health, and a vibrant life. In some traditions, it is believed to stimulate circulation and boost energy levels, both physically and emotionally. The stone's ability to "shine in midsummer" is a reflection of its association with peak energy and abundance.
Cultural Significance: The ruby's symbolic power is not confined to a single culture. It has decorated royal crowns and jewelry across the world, often as a symbol of power and divine favor. Its status as the "king of precious stones" in India and its revered place in Burmese lore highlight a global recognition of its exceptional significance.
Care and Cleaning
Given its exceptional hardness and durability, ruby is a relatively low-maintenance gemstone, ideal for jewelry intended for regular wear. However, proper care will ensure it retains its brilliance for generations.
Daily Wear Considerations: Thanks to its 9 on the Mohs scale, ruby is highly resistant to scratching from everyday materials. This makes it an excellent choice for rings, bracelets, and other pieces that might encounter abrasion. Its durability means it can withstand the rigors of daily life without significant risk of damage.
Cleaning Methods: Rubies can be safely cleaned using warm water, mild soap, and a soft brush. Ultrasonic cleaners are generally considered safe for rubies, as they are durable and can withstand the vibrations. However, it is always best to consult a professional jeweler for specific care instructions, especially if the ruby is set in a delicate or antique piece of jewelry. Avoid harsh chemicals and extreme temperature changes, which could potentially damage the stone or its setting over time.
Storage: When not being worn, ruby jewelry should be stored separately from other gems and metals to prevent scratching. A soft cloth pouch or a compartmentalized jewelry box is ideal.
