The ruby, a gemstone synonymous with fiery passion and regal splendor, stands as the designated birthstone for individuals born on July 22nd. As a member of the corundum mineral family, this vibrant red stone is distinguished by its exceptional hardness, second only to diamond, and a color that has captivated human imagination for millennia. The ruby is not merely a beautiful gem; it is a vessel of profound historical significance, cultural symbolism, and remarkable geological formation. Its journey from deep within the earth to the crowns of royalty and the settings of modern jewelry is a testament to its enduring allure. This article delves into the multifaceted nature of the ruby, exploring its history and lore, its geological origins and sources, its precise gemological properties, its symbolic meanings across cultures, and the practical considerations for its care and cleaning.
History and Lore
The ruby’s historical narrative is as rich and deep as its color. Revered across continents and epochs, this gemstone has been the subject of myth, legend, and unwavering desire. Ancient Indian texts, for instance, bestowed upon the ruby the title of “king of precious stones,” a moniker that underscores its rarity, hardness, beauty, and the seemingly mystical powers attributed to it. In the cultural tapestry of India, the ruby was intrinsically linked to the life force, symbolizing power, youthful energy, and vitality. It was believed that the stone’s intense red hue mirrored the essence of blood, connecting it to the very core of human existence.
This association with life force and power was not confined to the Indian subcontinent. In medieval Europe, rubies were thought to confer health, wisdom, and success in matters of the heart. The gemstone’s believed protective qualities were put to practical use by Burmese warriors, who carried rubies into battle with the conviction that the stone would render them invincible. This belief in the ruby’s protective and empowering properties has woven it into the fabric of various cultures, transforming it from a mere mineral into an object of spiritual and physical safeguarding.
The ruby’s journey to becoming a modern birthstone is part of a longer tradition of associating specific gems with months of the year, a practice that evolved over centuries. While the formalized lists of birthstones as we know them today have more recent origins, the ruby’s connection to July is deeply rooted in its historical and symbolic alignment with the passions and energies of the summer month. Its fiery red color is often seen as a perfect metaphor for the heat and intensity of July, making it a fitting emblem for those born during this period.
Geological Formation and Sources
The formation of a ruby is a geological marvel, requiring specific and rare conditions within the Earth’s crust. As a variety of the mineral corundum, ruby is essentially crystalline aluminum oxide (Al2O3). Its signature red color is not inherent to the corundum structure but is imparted by trace amounts of the element chromium. The presence of chromium during the crystal’s formation is the critical factor that differentiates red ruby from its blue and other colored sapphire counterparts within the same mineral family. The more chromium present, the more intense the red hue becomes.
Rubies are typically found in metamorphic rocks, where aluminum-rich rocks are subjected to high temperatures and pressures, often in the presence of silica and other minerals. The geological processes that create these conditions are complex and specific, contributing to the gemstone’s rarity. The primary sources of rubies mentioned in the provided materials are concentrated in a few key regions of the world, each known for producing stones with distinct characteristics.
Myanmar, historically known as Burma, is one of the most renowned sources for fine rubies, particularly from the Mogok region. Rubies from this area are often celebrated for their rich, "pigeon's blood" red color, a term used in the trade to describe the most prized hue. Thailand is another significant source, with its mining regions producing rubies that may exhibit slightly different color characteristics, often leaning toward a deeper red with brownish undertones. Additionally, materials indicate that Africa is a source for rubies, contributing to the global supply of this precious gem. The concentration of ruby mining in these specific geographic areas highlights the geological rarity of the gem and the importance of these locations in the global gemstone market.
Gemological Properties
The ruby’s esteemed status is firmly supported by its exceptional gemological properties, which make it one of the most durable and beautiful gemstones available for jewelry. Understanding these properties is essential for appreciating its value and for making informed decisions when purchasing or caring for ruby jewelry.
Color: The defining characteristic of a ruby is its color. The finest rubies exhibit a vibrant, deep red, sometimes with a subtle hint of purple. In the trade, the most coveted color is known as "pigeon’s blood," a term that refers to a pure, vivid red with a slight bluish tint. The color is directly influenced by the chromium content; higher levels of chromium typically produce a stronger and more desirable red. It is important to note that while the term "ruby" is reserved for the red variety of corundum, other colors of corundum are classified as sapphires.
Hardness and Durability: Rubies are among the toughest natural gems, scoring an impressive 9 out of 10 on the Mohs Hardness Scale. This places them second only to diamonds in hardness. This remarkable durability means that ruby jewelry is highly resistant to scratching and can withstand the rigors of daily wear with minimal signs of damage. The exceptional hardness of ruby rings, necklaces, and earrings makes them not only beautiful but also practical for everyday use, ensuring they can be cherished as heirloom pieces for generations.
Chemical Composition: As a variety of corundum, ruby has a chemical formula of Al2O3, with chromium as the trace element responsible for its red color. This simple yet stable composition contributes to its physical resilience and its ability to maintain its polish and luster over time.
Clarity and Cut: While not explicitly detailed in the provided sources, the clarity and cut of a ruby are critical factors in determining its quality and value. Like other gemstones, rubies can contain inclusions, which are natural internal features. The presence, type, and visibility of these inclusions affect the stone’s clarity grade. Similarly, the cut of a ruby—its proportions, symmetry, and polish—directly influences how light interacts with the stone, impacting its brilliance and overall visual appeal.

The ruby’s symbolism is as intense as its color, encompassing themes of love, power, vitality, and protection. Across different cultures and eras, the stone has been attributed with a wide range of metaphysical and spiritual meanings, many of which are rooted in its historical lore.
Love and Passion: The deep red of the ruby has universally been associated with the heart, blood, and intense emotion. It is a symbol of passionate love, making it a popular choice for romantic jewelry such as engagement rings and anniversary gifts. The stone’s connection to love is reinforced by its Latin-derived name, ruber, meaning red.
Power and Vitality: The ruby’s link to the life force is a recurring theme. In ancient India, it was thought to enhance youthful energy and vitality. Its perceived ability to invigorate the wearer is connected to its blood-like color, symbolizing strength and courage. This symbolism aligns with the belief that rubies can help individuals through life’s bold moments, reminding them of their inner power and worth.
Protection and Health: Historically, rubies were believed to possess protective qualities. The Burmese warriors’ faith in the stone’s ability to grant invincibility in battle is a prime example. Other historical beliefs suggested that rubies could predict misfortune or danger, while some claimed they had the power to cure inflammatory diseases and soothe anger. These metaphysical beliefs, while not scientifically verified, contribute to the ruby’s enduring mystique and cultural significance.
For those born on July 22nd, the ruby’s symbolism resonates with the astrological sign of Cancer, which is ruled by the Moon and is often associated with emotional depth, intuition, and nurturing qualities.

Care and Cleaning
Given the ruby’s exceptional hardness and durability, caring for ruby jewelry is relatively straightforward. However, proper maintenance is essential to preserve its beauty and structural integrity over time.
Daily Wear: The ruby’s 9 on the Mohs hardness scale makes it highly resistant to scratching from everyday abrasives. This durability allows ruby jewelry, including rings, bracelets, necklaces, and earrings, to be worn daily without significant risk of surface damage. Its resilience is a key reason why rubies are considered ideal for heirloom pieces that can be passed down through generations.
Cleaning: To clean ruby jewelry, a simple solution of warm water and mild dish soap is sufficient. Using a soft brush, such as a toothbrush with soft bristles, can help gently remove any dirt or oils that have accumulated in settings or on the stone’s surface. It is important to rinse the jewelry thoroughly with clean water and dry it with a soft, lint-free cloth. Avoid using harsh chemicals, ultrasonic cleaners, or steam cleaners unless you are certain that the setting and any other gemstones or materials in the piece can safely withstand such treatments. When in doubt, consulting a professional jeweler is always recommended.
Storage: When not in use, ruby jewelry should be stored separately from other pieces to prevent scratches. A fabric-lined jewelry box with individual compartments or soft pouches is ideal for protecting the gemstone’s polished surface.
