History and Lore: The King of Gems
The history of ruby is steeped in mythology and royal patronage, tracing back to some of the world's oldest civilizations. In ancient India, ruby was held in the highest esteem, earning the title “king of gems.” It was believed to possess a divine power that could protect its wearer from evil and misfortune. This belief was so deeply ingrained that warriors would embed rubies in their armor and skin, trusting in the stone's ability to safeguard them in battle. The gem was seen as a physical embodiment of life force, its blood-red color symbolizing the very essence of vitality and courage.
Across different cultures, ruby has been a consistent symbol of passion, love, and power. Its deep red color has long been associated with the heart and blood, making it a potent emblem of intense emotion. In European history, rubies adorned the crowns and regalia of monarchs, signifying wealth and authority. The gem's rarity and beauty made it a favorite among royalty and the aristocracy, further cementing its status as a gem of immense prestige.
The journey to becoming a modern birthstone is a more recent development, standardized through lists created by the National Association of Jewelers in the early 20th century. These lists aimed to provide a clear and consistent guide for consumers. Ruby was officially designated as the birthstone for July, a role it has fulfilled with distinction. This modern association builds upon its ancient lore, connecting those born in this month to a legacy of protection and passion. The ruby's historical narrative is not just a story of a gemstone but a reflection of humanity's enduring fascination with color, power, and the natural world's extraordinary creations. Its transformation from a mystical protector to a celebrated birthstone highlights its timeless appeal and cultural adaptability.
Geological Formation and Sources
Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). Its iconic red color is the result of trace amounts of chromium substituting for aluminum in the crystal lattice. The presence and concentration of chromium are critical; too little chromium yields a pale pink sapphire, while too much can cause the crystal to become opaque. The formation of ruby requires specific and intense geological conditions. It is typically found in metamorphic rocks, such as marble, and in alluvial deposits, where it has been eroded from its host rock and transported by water.
Historically, the most famous source of rubies was the Mogok region of Myanmar (formerly Burma), which has been producing gems of exceptional quality for centuries. These Burmese rubies are renowned for their rich, vibrant "pigeon's blood" red, a term used to describe the most desirable color. However, the political situation in Myanmar has made sourcing from this region challenging at times. In recent decades, significant new deposits have been discovered, diversifying the global supply. Mozambique, particularly the Montepuez area, has emerged as a major producer of high-quality rubies. Other important sources include Thailand, which has long been a central hub for ruby cutting and trading, as well as Sri Lanka, Vietnam, and Afghanistan.
The discovery of new deposits in Africa has had a profound impact on the ruby market. As noted in the sources, these discoveries have brought many attractive natural rubies into the market at more affordable prices. This increased availability has made ruby jewelry more accessible to a wider audience, democratizing a gem that was once exclusively reserved for the wealthy. While the allure of Burmese rubies remains strong, the modern gemologist must consider the diverse geographic origins of these stones, each offering a unique character and quality profile. The ongoing exploration and mining in these regions continue to shape the supply, pricing, and availability of this coveted July birthstone.
Gemological Properties: The Science of a Ruby
Understanding the gemological properties of ruby is essential for appreciating its value and durability. As a member of the corundum family, it shares characteristics with sapphire, its close mineralogical relative. The key properties that define a ruby are its color, hardness, clarity, and chemical composition.
Color: This is the single most important factor in determining a ruby's value. The finest rubies exhibit a pure, vibrant red to slightly purplish-red hue. The color must be neither too orangey nor too purplish, as these deviations lower the value. Saturation is also critical; the color should be vivid and intense, not washed out or overly dark. The sources mention that rubies range in color from "orangy-red, to red, to slightly purplish-red," with the most desirable being "pure red and slightly purplish red."
Hardness and Durability: Ruby is one of the hardest minerals on Earth, rating a 9 on the Mohs scale of hardness. This exceptional hardness means it is highly resistant to scratching and abrasion, making it an excellent choice for all types of jewelry, including rings and bracelets that are subject to daily wear. Only diamond (10) and moissanite (9.25) are harder. However, like all gemstones, it is not indestructible and can be chipped or fractured by a hard blow due to its cleavage properties.
Clarity: Most natural rubies contain inclusions, which are internal features that distinguish them from lab-grown specimens. 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 be detrimental, others, like fine silk (tiny rutile needles), can sometimes enhance the stone's color by scattering light and may even be a telltale sign of natural origin.
Chemical Composition: As noted, ruby is aluminum oxide (Al₂O₃) with chromium as the chromophore element responsible for its color. The specific trace element chemistry is what separates ruby from other corundum varieties.

Symbolism and Metaphysical Beliefs
The symbolism associated with ruby is as intense and vibrant as its color. Across ages and cultures, it has been imbued with powerful meanings, ranging from protection and prosperity to love and passion. These beliefs have contributed to its enduring mystique and its status as a gem of profound significance.
In ancient Hindu tradition, ruby was believed to be the "king of gems," a title that speaks to its perceived supremacy. It was thought to protect its wearer from evil, danger, and negative energies. This protective quality was not limited to the spiritual realm; it was believed that wearing a ruby could safeguard one's physical well-being, making it a popular talisman for soldiers and travelers. The stone was also associated with wealth and prosperity, thought to bring good fortune and success to its owner.
The connection between ruby and matters of the heart is a powerful and persistent theme. Its deep red color has made it a universal symbol of love, passion, and romance. Today, the deep red color of the ruby is widely understood to signify love and passion, making it a popular choice for engagement rings and anniversary gifts. This symbolism transcends simple aesthetics, representing a deep emotional connection and enduring commitment. The gem is seen as a reflection of the heart's most powerful emotions, a stone that embodies the fire of desire and the strength of true affection.
Beyond these core beliefs, some traditions have also linked ruby to vitality and life force. Its color, reminiscent of blood, has led to associations with energy, courage, and overcoming exhaustion. For those born in July, the ruby is said to bestow these qualities upon its wearer, acting as a source of strength and motivation. This rich tapestry of symbolism and metaphysical belief adds a layer of intangible value to the ruby, making it much more than just a beautiful stone.
The Rise of Lab-Grown Ruby
In recent decades, the market for ruby has been significantly transformed by the advent of advanced lab-grown technology. Lab-grown, or synthetic, ruby is chemically, physically, and optically identical to its natural counterpart. The only difference lies in its origin: one is created deep within the Earth over millions of years, while the other is produced in a controlled environment in a matter of weeks. This technological advancement has made ruby more accessible than ever before.
Lab-grown rubies have been a presence in the United States jewelry market since the early 1900s. Initially, they were a novelty, but today, they are a common sight in major jewelry retail chains. As the sources point out, if one were to visit a mall jewelry store, it is highly likely that a large assortment of ruby jewelry would be synthetic. These lab-grown gems often possess superior clarity and color when compared to natural rubies of a similar price point. This is because scientists can control the growth process to minimize inclusions and produce a more consistent, vibrant red hue.
The primary advantage of lab-grown ruby is affordability. Natural rubies of high quality are exceptionally rare and command very high prices. Lab-grown alternatives, however, can be purchased for a fraction of the cost, making a beautiful red gemstone accessible to a much broader audience. This has allowed more people to enjoy the beauty and symbolism of ruby without the significant financial investment required for a natural stone.
However, the rise of lab-grown gems also brings with it an important ethical and commercial responsibility: disclosure. It is crucial that the origin of the gemstone is clearly communicated to the buyer. The sources emphasize that selling synthetic gems without clearly disclosing their man-made origin is a violation of industry regulations and ethical practices. Consumers who prefer natural gems must be able to make an informed choice. For many, the lower cost and flawless appearance of a lab-grown ruby are perfect, but transparency is paramount to maintaining trust and integrity within the jewelry market.
Care and Cleaning: Preserving the King's Brilliance
Given its exceptional hardness and durability, ruby is a relatively easy gemstone to care for, but it still requires proper attention to maintain its beauty. Its 9 on the Mohs scale makes it resistant to everyday scratches and wear, making it suitable for rings, earrings, and bracelets. However, proper cleaning and storage are essential to ensure it remains in pristine condition.
Cleaning: The best way to clean a ruby is with warm, soapy water and a soft brush, such as a toothbrush. Gently scrub the back and front of the stone, as well as the setting, to remove any accumulated oils, dirt, or dust. Rinse thoroughly with clean water to remove any soap residue. It is also safe to use commercial jewelry cleaning solutions that are specifically designed for hard gemstones. Ultrasonic cleaners are generally safe for untreated and heat-treated rubies, but caution should be exercised if the stone has been fracture-filled or if the jewelry has a delicate setting. Steam cleaning is also typically safe, but again, avoid it if the stone has been treated with fillers.
Storage: When not being worn, ruby jewelry should be stored carefully to prevent it from scratching other, softer gemstones or being scratched itself. While ruby is very hard, it can still be damaged by harder materials like diamond or moissanite. It is best to store ruby pieces in a soft cloth pouch or in a separate compartment of a jewelry box. This simple step can prevent accidental damage and keep the stone's polish looking its best.
Considerations for Settings: While the ruby itself is tough, the setting can be a point of vulnerability. It is important to have the setting checked periodically by a professional jeweler to ensure the prongs are secure. A loose setting can lead to the stone falling out and being lost or damaged. Additionally, while ruby is durable, a sharp, hard blow can cause it to chip or fracture, so it is wise to remove ruby jewelry during activities that could subject it to impact.
By following these simple care guidelines, the owner of a ruby can ensure that this "king of gems" will retain its fiery brilliance and protective symbolism for generations to come.
