History and Lore of the Ruby
The historical narrative of the ruby is steeped in reverence and legend, tracing back to some of the world's oldest civilizations. In ancient India, the ruby was revered as the “king of precious stones.” This title was not bestowed lightly; it was a direct result of the gem’s perceived rarity, its formidable hardness, and its captivating color. Indian lore often associated the ruby with the life force of blood, viewing it as a powerful symbol of vitality, power, and youthful energy. It was believed to be a stone of great significance, one that could offer protection and enhance the wearer’s strength. This deep connection to life and power made it a favored gem in Indian jewelry, often worn by royalty and the elite to signify their status and divine favor.
This reverence was not confined to India. In Burmese traditions, the ruby held a similarly esteemed position. Burmese warriors, in particular, placed great faith in the protective powers of the gem. They believed that carrying a ruby into battle would render them invincible, a belief that speaks to the stone’s long-standing association with courage and protection. The ruby’s deep red color, often described in the trade as “pigeon’s blood,” was seen as a visual manifestation of these powerful attributes. This specific hue, a deep red with a hint of purple, is considered the finest color for a ruby and has been a benchmark for quality for centuries.
Beyond the East, the ruby’s symbolism continued to evolve. In past centuries, the gem was attributed with both protective and predictive powers. Some believed it could forewarn of misfortune or danger, acting as a talisman against harm. Others claimed it possessed healing properties, specifically the ability to cure inflammatory diseases and soothe anger. These beliefs, while not supported by modern science, highlight the profound cultural and spiritual weight the ruby carried. Its association with love and passion, derived from its fiery red color, made it a popular choice for romantic jewelry, a tradition that continues to this day. The ruby’s journey through history is one of consistent admiration, from ancient warriors seeking invincibility to modern individuals seeking a symbol of enduring love and passion.
Geological Formation and Sources
The ruby’s creation is a testament to the powerful geological forces that shape our planet. As a variety of the mineral corundum, which is crystalline aluminum oxide (Al₂O₃), the ruby forms under specific and extreme conditions. The presence of trace amounts of the element chromium is what gives the ruby its characteristic red color; the more chromium present, the more intense the red hue. Other impurities, such as iron, can influence the color, sometimes adding brownish or purplish tones. The formation of corundum requires high temperatures and pressures, typically occurring in metamorphic rocks or in certain types of pegmatites.
Significant sources of ruby have been identified in various parts of the world, each producing stones with unique characteristics. Historically, the most prized rubies have come from the Mogok region of Myanmar (formerly Burma). Burmese rubies are renowned for their vibrant, saturated “pigeon’s blood” color, a standard against which other rubies are often judged. Another important source is the Montepuez region in Mozambique, which has become a major producer of high-quality rubies in recent decades. Rubies are also mined in other locations, including Vietnam, Sri Lanka, and parts of Africa and Asia. The United States even has locations where rubies can be found, with some sources noting that there are places where enthusiasts can legally dig for them, adding an element of adventure to the gem’s allure.
The rarity of high-quality rubies cannot be overstated. Fine rubies are significantly rarer than diamonds, which contributes to their high market value. The geological conditions required for the formation of large, clean, and vividly colored rubies are uncommon, making every significant find a notable event in the gemological world. The mining process is often labor-intensive and requires great skill to extract the gems without damaging them. Once mined, the rough ruby must be expertly cut to maximize its color and brilliance, a process that requires an understanding of the stone’s crystal structure and optical properties. The journey from a mineral in the earth to a polished gemstone is a long and complex one, adding to the ruby’s mystique and value.
Gemological Properties
Understanding the gemological properties of the ruby is essential for appreciating its value and ensuring its proper care. The ruby’s physical and optical characteristics are what make it both a durable gemstone for jewelry and a subject of scientific study.
Hardness and Durability: One of the ruby’s most remarkable attributes is its hardness. On the Mohs Hardness Scale, a standard measure of a mineral's scratch resistance, the ruby scores an impressive 9 out of 10. This places it second only to diamond, which is the hardest known natural material (10 on the Mohs scale). This exceptional hardness means that ruby jewelry is highly resistant to scratching and can withstand daily wear with minimal risk of damage. It is this durability, combined with its beauty, that makes the ruby an excellent choice for all types of jewelry, including rings and bracelets that are subject to frequent contact.
Color: Color is the most critical factor in determining a ruby’s value. The finest rubies exhibit a deep, vibrant red with a slight purples undertone, known in the trade as “pigeon’s blood.” This specific color is highly coveted and commands the highest prices. The red coloration is caused by chromium, as previously mentioned. Rubies can also display a range of red hues, from light pinkish red to a deep, almost brownish red. The presence of other trace elements, like iron, can affect the saturation and undertone of the red. It is important to note that the term “ruby” is strictly applied to the red variety of corundum; all other colors of corundum are classified as sapphires.
Clarity and Inclusions: Like most natural gemstones, rubies almost always contain inclusions—internal characteristics such as minerals, feathers, or tiny fractures. In fact, a completely flawless ruby is exceptionally rare. The type, size, and location of these inclusions affect the stone’s clarity grade and, consequently, its value. While some inclusions can diminish a ruby’s beauty, others can be accepted if they do not significantly impact the stone’s overall appearance or durability. Certain types of inclusions, like fine silk (tiny rutile needles), can even be desirable as they may soften the color and provide evidence of the stone’s natural origin.
Cut and Carat Weight: The cut of a ruby is crucial for showcasing its color. Gem cutters must skillfully shape the rough stone to maximize its color saturation and brilliance. Common cuts for rubies include oval, cushion, and round brilliant cuts, which are chosen to best display the stone’s hue. Carat weight refers to the ruby’s size; as with other gemstones, larger rubies are exponentially rarer and more valuable per carat than smaller ones. However, color remains the primary driver of value; a smaller ruby with an exceptional “pigeon’s blood” color can be worth more than a larger stone with a less desirable hue.

In many traditions, the ruby is seen as a stone that can rekindle love and maintain the spark in long-term relationships.
Power and Protection: Historically, the ruby has been a talisman of power and protection. From the ancient Indian kings to the Burmese warriors, the stone was worn as a shield against harm and a source of strength. It was thought to guard against negative energies and physical danger. This protective quality is still valued today, with many people wearing rubies as amulets for personal safety and to ward off misfortune. The belief in the ruby’s power to grant invincibility and divine favor underscores its role as a stone of courage and authority.
Vitality and Health: The ruby’s connection to blood and life force extends to metaphysical beliefs about health and vitality. It is often associated with stimulating the body’s energy, boosting circulation, and enhancing overall vitality. Some traditions hold that the ruby can purify the body and blood, and its red color is linked to the root chakra, which governs grounding, survival, and physical energy. While these are metaphysical beliefs and not scientifically proven, they contribute to the ruby’s enduring appeal in holistic and spiritual practices.
Alternative Birthstones for July: While the ruby is the primary birthstone for July, some frameworks recognize other stones for this month, particularly for specific dates like July 20th. These alternatives offer different symbolic meanings: - Onyx: A black or banded chalcedony associated with protection, strength, and grounding. It provides a sense of balance and stability. - Turquoise: A blue-green gemstone known for its calming properties, believed to promote healing and emotional balance. - Sardonyx: A type of onyx with reddish-brown bands, linked to courage and determination. - Sapphire: While primarily associated with September, some traditions include it for July. It is linked to wisdom, clarity, and spiritual insight.
These alternative stones provide a diverse range of choices for individuals born in July, each with its own unique energy and history.
Care and Cleaning
The ruby’s exceptional hardness makes it one of the most durable gemstones for jewelry, but it still requires proper care to maintain its brilliance and integrity. While resistant to scratching, rubies can be damaged by sharp blows or extreme temperature changes, which could cause fractures.
Cleaning: The safest way to clean ruby jewelry is with warm, soapy water and a soft brush, such as a toothbrush. Gently scrub the stone and its setting to remove dirt and oils. Rinse thoroughly with clean water and dry with a soft, lint-free cloth. It is important to avoid harsh chemicals, such as bleach or ammonia, which can damage the metal settings or, in rare cases, affect certain treatments. Ultrasonic cleaners are generally safe for untreated rubies but should be used with caution for stones that have been fracture-filled or treated, as vibrations could potentially loosen the filler. Steam cleaning is not recommended for rubies with significant inclusions or fractures, as the heat and pressure could exacerbate them.
Storage: When not being worn, ruby jewelry should be stored separately from other pieces to prevent scratching. A soft pouch or a compartmentalized jewelry box is ideal. Avoid exposing rubies to extreme temperatures, such as leaving them in direct sunlight for prolonged periods or placing them near heat sources, as this could potentially affect the stone’s color or cause damage over time.
Professional Inspection: It is advisable to have ruby jewelry professionally inspected by a qualified jeweler at least once a year. The jeweler can check the security of the setting, clean the piece thoroughly, and identify any potential issues with the stone or its mounting. This proactive care helps ensure that the jewelry remains safe and beautiful for years to come.
