History and Lore
The name "ruby" is derived from the Latin word ruber, meaning "red," a simple yet direct testament to the gemstone's defining characteristic. Historical references to this gem appear in the writings of ancient Greeks and Romans, indicating its early recognition and value. For centuries, ruby has been revered as one of the most precious gemstones in human history, its deep red color earning it a place in the adornments of royalty, warriors, and spiritual leaders across diverse cultures and eras.
In ancient times, the ruby was believed to possess extraordinary protective powers. Warriors would often carry rubies into battle, convinced that the stone would grant them courage and shield them from harm. The stone's association with blood and the heart fueled beliefs in its life-giving properties. In various cultures, rubies were thought to embody the essence of life itself, symbolizing vitality, health, and the very force of existence. This connection to the heart also positioned the ruby as a stone of harmony, believed to promote peace and contentment within relationships. It was often given as a gift to express deep emotions and unwavering commitment.
The historical significance of the ruby is further cemented by its frequent appearances in royal regalia. Many ancient and medieval crowns were decorated with rubies, symbolizing power, divine favor, and wealth. The gemstone’s rarity and beauty made it a fitting emblem for monarchs, who believed it offered protection and enhanced their authority. This royal legacy continues to this day, with rubies remaining a centerpiece in many state jewels and high-end jewelry collections.
It is important to note that while the modern birthstone calendar uniformly assigns ruby to the month of July, historical variations existed. Sources indicate that other stones, such as onyx, sapphire, and sardonyx, were associated with July in different cultures and time periods. For instance, the ancient Russian calendar listed sardonyx as the July birthstone, while the Hindu calendar assigned sapphire to this month. In the Arabic tradition, carnelian held the role. Despite these historical alternatives, ruby has emerged as the dominant and most widely recognized July birthstone in contemporary times, solidifying its status as the primary gem for those born in the summer month, including the specific date of July 5.
Geological Formation and Sources
Rubies belong to the corundum family of minerals, a group that also includes sapphires. The fundamental chemical composition of corundum is aluminum oxide (Al₂O₃). The gemstone’s brilliant red color is not inherent to the mineral itself but is caused by trace impurities. Specifically, the presence of chromium (and less commonly, vanadium) during its formation is what gives ruby its characteristic and coveted red hue. The intensity and quality of the red color are directly related to the concentration of these trace elements.
The formation of ruby is a remarkable geological process that occurs deep within the Earth's crust under conditions of extreme temperature and pressure. These gemstones typically form in metamorphic rocks, such as marbles and gneisses, where aluminum and silica-rich rocks are subjected to intense heat and pressure over millions of years. The specific geological environment must also contain the necessary chromium for the color to develop, making the formation of gem-quality ruby a relatively rare event.
Significant ruby deposits have been discovered in various locations around the world, each producing stones with unique characteristics. Historically, the most prized rubies have come from the Mogok region of Myanmar (formerly Burma), known for producing rubies with a rich, "pigeon's blood" red color. Other notable sources include Thailand, which has been a major trading center for rubies for centuries, and Sri Lanka, which produces lighter-toned rubies. More recently, deposits in Mozambique and Tanzania have gained prominence in the global market. The geographical origin of a ruby can influence its value, with Burmese rubies traditionally commanding the highest prices due to their superior color and clarity.
Gemological Properties
The ruby is celebrated not only for its beauty but also for its exceptional physical properties, which make it one of the most durable gemstones available for jewelry. Its key gemological characteristics are as follows:
- Hardness: On the Mohs scale of mineral hardness, ruby scores an impressive 9 out of 10. This makes it second only to diamond in hardness, meaning it is highly resistant to scratching and abrasion. This remarkable durability ensures that ruby jewelry can withstand daily wear without significant damage, making it an ideal choice for rings, bracelets, and other pieces subject to frequent use.
- Chemical Composition: As a variety of corundum, ruby has a chemical formula of Al₂O₃. The red coloration is attributed to trace amounts of chromium (Cr³⁺) replacing aluminum in the crystal lattice.
- Crystal System: Ruby crystallizes in the trigonal system, forming hexagonal prisms that can be cut into various shapes to maximize their brilliance and color.
- Refractive Index: Ruby has a refractive index ranging from approximately 1.762 to 1.770, contributing to its excellent light performance and sparkle when properly cut.
- Specific Gravity: The specific gravity of ruby typically falls between 3.99 and 4.01, a measure of its density.
- Clarity and Inclusions: Natural rubies often contain inclusions, which are internal characteristics such as silk (fine rutile needles) or fingerprint-like fluid inclusions. While flawless rubies are extremely rare and valuable, some inclusions are accepted and even expected in natural stones. The presence and type of inclusions can be used to determine a ruby's origin and natural status.
- Color: The most valued ruby color is a vivid, pure red with a slight bluish undertone, often described as "pigeon's blood." Colors can range from orangey-red to purplish-red, with the most desirable hue being a medium to medium-dark tone of intense saturation.
The following table summarizes the key gemological properties of ruby:

Care and Cleaning
Due to its exceptional hardness, the ruby is relatively easy to care for and maintain. However, proper handling and cleaning are essential to preserve its beauty and longevity, especially when set in jewelry.
General Care Tips: * Storage: Store ruby jewelry separately from other jewelry to prevent scratches, even though ruby is very hard. A soft-lined jewelry box or individual pouches are ideal. * Avoid Harsh Chemicals: While ruby is resistant to most chemicals, prolonged exposure to harsh substances like bleach or chlorine can damage the setting or affect the stone's polish. It is advisable to remove ruby jewelry before swimming or cleaning with strong chemicals. * Physical Impact: Although ruby is durable, a hard blow against a solid object could potentially cause chipping or fracture, particularly if the stone has pre-existing inclusions. It is best to remove ruby rings during heavy manual work or sports.
Cleaning Instructions: The most effective and safe method to clean ruby jewelry is using warm water, mild dish soap, and a soft brush (such as a toothbrush). Gently scrub the stone and its setting to remove any dirt or oils. Rinse thoroughly with clean water to ensure no soap residue remains. Dry the jewelry with a soft, lint-free cloth. Avoid using ultrasonic cleaners or steam cleaners, especially if the ruby has been fracture-filled or if the jewelry has a delicate setting, as these methods can cause damage.
For professional cleaning or if the jewelry requires inspection for loose stones or worn settings, it is recommended to consult a trusted jeweler or gemologist.
