Yet, its rarity and the intense, vibrant color of the finest specimens have commanded the highest value among all colored birthstones. This article delves into the multifaceted world of the July birthstone, exploring its rich history and lore, its geological origins and sources, its precise gemological properties, and the enduring metaphysical beliefs that continue to attract enthusiasts, buyers, and students of gemology to this day.
History and Lore: The King of Precious Stones
The ruby’s esteemed reputation is not a modern invention; it is deeply rooted in ancient civilizations that revered the stone for its perceived mystical powers and regal appearance. In ancient India, ruby was celebrated as the "king of precious stones." This title was bestowed upon it not only for its rarity and exceptional hardness but also for its beauty and the seemingly mystical powers attributed to it. The stone's deep red hue was consistently associated with the life force of blood, making it a powerful symbol of youthful energy and power in Indian jewelry. For centuries, it was believed that wearing a ruby could ward off misfortune and danger, with some even claiming it could cure inflammatory diseases and soothe anger.
This reverence for the ruby was not confined to the East. The stone’s legend traveled across continents, capturing the imagination of various cultures. A notable example comes from the Burmese warriors who held a profound belief in the gemstone's protective powers. They were convinced that embedding rubies into their flesh or carrying them into battle would render them invincible. This practice underscores the deep-seated belief in the ruby as a talisman for protection and strength, a theme that resonates throughout its history.
The journey of ruby through history is also marked by its association with royalty and divine favor. Across many cultures and eras, rubies have been used to decorate royal crowns and jewelry, serving as potent symbols of power and status. This association with the elite further cemented its position as a gemstone of immense value and prestige. The historical narrative of ruby is a testament to its enduring appeal, moving from ancient talismans of protection to cherished adornments of the powerful, all while maintaining its core symbolism of love, passion, and vitality.
The ruby's path to becoming the official July birthstone was solidified in the 20th century. While it has long been associated with the month, its formal adoption was a more recent development. Prior to 1912, when the Jewelers of America officially designated ruby as the birthstone for July, other gems such as onyx and turquoise were also considered appropriate for those born in this month. This historical context highlights the evolution of birthstone lists and the eventual recognition of ruby's preeminence.
Geological Formation and Sources
Ruby is a variety of the mineral corundum, which is a crystalline form of aluminum oxide (Al2O3). What distinguishes ruby from other corundum varieties is its distinctive red color, which is caused by trace amounts of the element chromium. The presence and concentration of chromium are critical; the more chromium present in the mineral's crystal lattice, the stronger and more vibrant the red hue will be. This specific geological condition is relatively rare, contributing to the gem's overall scarcity and value. While corundum occurs in many colors, only the red variety is classified as ruby. All other colors of corundum are considered sapphires, with blue sapphire being the most common and well-known gem variety besides ruby.
The formation of ruby requires specific and intense geological conditions, typically involving the metamorphism of aluminum-rich rocks under high temperatures and pressures. These processes occur deep within the Earth's crust over millions of years. The resulting crystals are then brought to the surface through geological events and are subsequently mined from alluvial deposits or primary rock formations.
While the provided sources do not offer an exhaustive list of modern mining locations, they provide a rich historical context for the geographical origins of some of the world's most famous rubies. The lore and history of the gemstone are intrinsically linked to specific regions. For instance, the reverence for ruby in ancient India points to the subcontinent as a historical source of these gems. Similarly, the beliefs of Burmese warriors suggest that the regions of modern-day Myanmar (Burma) were also a significant source of high-quality rubies, known for their exceptional color and were the origin of the "pigeon's blood" color description. These historical sources confirm that the ruby has been sourced and traded from Asia for centuries, forming a key part of the gem's identity and mystique. The geological rarity and the specific locations where these conditions are met continue to make ruby one of the most sought-after gems in the world.
Gemological Properties
Understanding the gemological properties of ruby is essential for appreciating its value and durability. As a member of the corundum family, it shares many characteristics with sapphire but is defined by its red coloration. These properties are what make it not only beautiful but also one of the most practical gemstones for jewelry.
Durability and Hardness One of the most remarkable attributes of ruby is its exceptional durability. It ranks an impressive 9 out of 10 on the Mohs Hardness Scale, making it the second hardest natural mineral after diamond. This remarkable strength means that ruby jewelry is highly resistant to scratching and abrasion, allowing it to handle daily wear without showing signs of damage. This resilience makes it an ideal choice for rings, bracelets, and other pieces that are subject to frequent use, ensuring its beauty endures for generations.
Color Color is the most critical factor in determining a ruby's quality and value. The finest color of the birthstone for July is a deep red with a hint of purple. In the gem trade, this specific, highly prized hue is known as "pigeon's blood." The color originates from trace amounts of chromium within the corundum crystal. The intensity and saturation of the red are directly proportional to the amount of chromium present. This trace element is what transforms what would otherwise be a colorless sapphire into the vibrant, fiery red gem known as ruby.
Chemical Composition As mentioned, ruby is the gem form of crystalline aluminum oxide (Al2O3). Its chemical formula is what gives corundum its inherent hardness. The trace element chromium (Cr) substitutes for some of the aluminum atoms in the crystal structure, which is what gives ruby its red color. This simple yet precise chemical makeup is the foundation of the gem's most prized characteristics.

Symbolism and Metaphysical Beliefs
The ruby's symbolism is as intense and vibrant as its color. Across cultures and through the ages, it has been a powerful emblem of life's most potent forces. The stone's deep red color has long been associated with blood, fire, and passion, making it a universal symbol of life force, vitality, and love. This connection to blood is not merely poetic; it is a fundamental part of the ruby's lore, linking it to the very essence of existence.
In the context of modern metaphysical beliefs, the ruby is believed to bring good fortune, passionate love, and protection to those born in July. It is seen as a stone that can amplify life force energy, making it an excellent tool for motivation and emotional strength. The ruby is associated with the heart chakra, the energy center related to love and compassion. By activating this chakra, it is thought to bring vitality, love, and courage to its wearer.
The historical beliefs surrounding the ruby's protective powers are particularly compelling. As previously noted, Burmese warriors carried rubies into battle, convinced of their invincibility. This ancient belief in the stone's ability to ward off danger and misfortune continues in some modern interpretations. Some historical sources also suggest that rubies were believed to have the power to predict misfortune, acting as a warning system for their owners. Furthermore, the stone was historically thought to have curative properties, with some believing it could cure inflammatory diseases and soothe anger. These metaphysical attributes, from passion and protection to vitality and healing, contribute to the ruby's enduring mystique and its appeal to those seeking not just a beautiful gem, but one with deeper meaning.
Care and Cleaning
Given its exceptional hardness and durability, caring for ruby jewelry is relatively straightforward. A ruby's resistance to scratching and everyday wear makes it a low-maintenance gemstone, but proper care will ensure it retains its brilliance for a lifetime.
The high hardness of ruby (9 on the Mohs scale) means it can be safely cleaned with warm water, a mild soap, and a soft brush. Ultrasonic cleaners are generally safe for ruby jewelry, provided the stone has not been treated or fracture-filled. However, it is always best to consult with a professional jeweler before using such devices, especially if the ruby is set in a piece with other, more delicate gemstones.
While ruby is very tough, it is still important to protect it from hard blows, as any gemstone can be chipped or fractured with sufficient force. It is also advisable to store ruby jewelry separately from other jewelry pieces to prevent it from scratching softer gems. By following these simple care instructions, the owner of a ruby can preserve its fiery beauty and structural integrity.
