Its significance is rooted not only in its rarity and beauty but also in the powerful attributes ascribed to it across various cultures and eras. This guide will delve into the multifaceted nature of the July birthstone, offering a comprehensive resource for gemstone enthusiasts, collectors, and anyone born under the influence of this fiery gem.
History and Lore: The King of Precious Stones
The history of the ruby is as vibrant and intense as its color. The name "ruby" itself is derived from the Latin word ruber, meaning "red," a direct reference to the gem's most defining characteristic. For millennia, this gem has been held in the highest esteem, often considered more valuable than diamonds in certain ancient societies. Its rarity, exceptional hardness, and captivating beauty contributed to its legendary status.
In ancient India, the ruby was known as the "king of precious stones," a title that speaks to its perceived superiority over all other gems. This reverence was not based on aesthetics alone; the stone was believed to possess potent mystical powers. It was strongly associated with the life force of blood, symbolizing power, youthful energy, and vitality. Indian lore held that rubies were worn by warriors to grant them invincibility in battle and by royalty as a clear symbol of power and prosperity. This belief in its protective qualities was so strong that some cultures thought the gem could predict misfortune or danger, while others claimed it could cure inflammatory diseases and soothe anger.
This warrior-centric lore was not confined to India. Burmese warriors also held the belief that rubies made them invincible in battle, embedding the stones under their skin for protection. The connection between the ruby's color and the lifeblood of the body made it a powerful talisman across many cultures. Its use in crowns and scepters throughout history further cements its association with royalty and prestige. The gem was not just an ornament but an emblem of authority and divine right, believed to connect the wearer to the earth's powerful energies.
The journey of the ruby from an ancient talisman to a modern birthstone is a testament to its enduring appeal. The establishment of birthstones as we know them today has evolved over centuries, but the ruby's place as the stone for July has remained consistent. Its symbolism has adapted over time, yet core themes of passion, love, and protection persist. Today, the ruby continues to be regarded as a stone of determination and ambition, encouraging individuals to pursue their goals with vigor and resilience, echoing the courage it was once believed to grant to ancient warriors.
Geological Formation and Sources
The ruby is a variety of the mineral corundum, which is aluminum oxide (Al₂O₃). Its formation is a geological marvel, requiring specific and extreme conditions. The presence of trace amounts of the element chromium is what imparts the ruby's signature red color. The intensity of the red is directly proportional to the amount of chromium present in the crystal structure during its formation. This substitution of aluminum atoms by chromium atoms is what differentiates red corundum (ruby) from other colors of corundum, such as sapphire.
The formation of corundum typically occurs in metamorphic rocks, where aluminum-rich, silica-poor rocks are subjected to intense heat and pressure. This process can happen in geological environments such as marble deposits or in aluminum-rich igneous rocks like syenite. The chromium that provides the color is often sourced from the surrounding host rock. The conditions must be just right for the chromium to be incorporated into the corundum lattice without being present in such high concentrations that the crystal's growth is inhibited.
Historically, the most significant and renowned sources of high-quality rubies have been in Southeast Asia. The Mogok Valley in Burma (now Myanmar) is legendary in the gem world, having produced some of the finest "pigeon's blood" rubies for centuries. The rubies from this region are often found in marble deposits, a result of metamorphism of limestone, which gives them a unique character and often a strong fluorescence. Another important historical source is the Mong Hsu region of Burma, which began producing rubies in the 1990s. These rubies are known for their distinct bluish-red core, which is often treated with heat to improve their color.
In addition to Burma, other notable sources have emerged. Thailand has long been a major hub for the ruby trade, particularly for stones from the Chanthaburi and Trat provinces. Thai rubies are often darker and have a more brownish hue compared to their Burmese counterparts, but they are still highly valued. Vietnam has also become an important source of rubies, producing gems with color similar to those from Burma.
More recently, Africa has entered the ruby market with significant discoveries. Countries such as Mozambique, Tanzania, and Madagascar are now producing rubies of considerable quality. African rubies can display a wide range of colors and clarities, and their increased availability has made rubies more accessible to a broader market. Each geographic source imparts subtle characteristics to its rubies, making the origin an important factor for gemologists and collectors in evaluating a stone's value.
Gemological Properties
Understanding the gemological properties of the ruby is essential for appreciating its value and durability. These scientific characteristics define the stone and are used to assess its quality. As a member of the corundum family, the ruby shares many properties with sapphire, but its red color sets it apart.

Color: The most critical factor in determining a ruby's value is its color. The most prized color is a deep, vivid red with a slight purplish hue, a shade famously referred to in the trade as "pigeon's blood." This term describes a pure, vibrant red with a subtle blue undertone that is exceptionally rare and commands the highest prices. The color of a ruby is a result of the chromium content; the more chromium present, the more intense the red. Rubies can also exhibit shades of pinkish-red, orangey-red, or brownish-red, with the value decreasing as the stone moves away from the pure, saturated red.
Clarity: Due to the conditions of their formation, most natural rubies contain inclusions. It is often said that a "flawless" ruby is exceptionally rare, and the presence of inclusions can be an indicator of a natural, untreated stone. While inclusions can affect a ruby's clarity and transparency, some inclusions, like fine silk (rutile needles), can be desirable as they may enhance the stone's color through optical phenomena or prove its natural origin.
Hardness and Durability: With a rating of 9 on the Mohs scale of hardness, ruby is an exceptionally durable gemstone, second only to diamond. This remarkable hardness makes it an ideal choice for all types of jewelry, especially for pieces like engagement rings and daily-wear rings that are subject to frequent impact and abrasion. Its durability ensures that a ruby can be passed down through generations with proper care.
Cut and Carat: Rubies are cut into a variety of shapes, including oval, cushion, round, and emerald cuts, to best showcase their color and minimize the visibility of inclusions. The weight of a ruby is measured in carats. As with other gemstones, the price per carat increases exponentially with size, especially for high-quality stones with superior color and clarity.
Symbolism and Metaphysical Beliefs
The ruby's symbolism is deeply intertwined with its fiery color and historical lore. Across cultures and through the ages, it has been regarded as a powerful stone representing a wide spectrum of positive attributes. These beliefs range from ancient protective talismans to modern associations with love and emotional well-being.
Core Symbolism
- Passion and Love: The ruby's intense red has made it a universal symbol of love, passion, and romance. It is often associated with the heart and is believed to inspire deep emotional connections and strengthen romantic relationships. In the July Birthstone Guide, rubies are explicitly linked to these powerful emotions.

- Courage and Confidence: The ruby is thought to inspire courage and confidence, helping individuals to overcome challenges and face adversity with strength. It is a stone of determination, encouraging resilience and a bold pursuit of one's ambitions.
Metaphysical Beliefs
In the realm of crystal healing and metaphysical beliefs, the ruby is considered a highly energetic stone. It is often associated with the root chakra, the energy center located at the base of the spine, which governs feelings of grounding, stability, and physical health. It is believed that wearing a ruby can help balance and activate the root chakra, promoting a sense of security and well-being.
The ruby is also considered a stone of spiritual awakening and integration. It is said to stimulate the flow of life-force energy throughout the body, amplifying personal power and bringing forth positive emotions.

Care and Cleaning
Given its exceptional hardness and durability, the ruby is a relatively easy gemstone to care for, making it an excellent choice for jewelry that is worn regularly. However, proper care is still necessary to maintain its brilliance and ensure its longevity.
Hardness and Durability: With a Mohs hardness of 9, ruby is resistant to scratching by most other materials. It is durable enough to withstand daily wear without significant risk of damage. However, like all gemstones, it is not indestructible and can be chipped or fractured by a hard blow against a hard surface.
Cleaning Instructions: 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 dirt or oils that have accumulated. Rinse thoroughly with clean water to remove any soap residue. It is advisable to avoid harsh chemicals, such as bleach or chlorine, as they can potentially damage the metal settings. Additionally, while ruby is generally stable, it is best to avoid exposing it to extreme temperatures or sudden temperature changes, which could cause fractures in the stone, especially if it has been treated or has existing inclusions. Ultrasonic cleaners are generally safe for untreated and heat-treated rubies, but stones that have been fracture-filled or dyed should not be cleaned with this method.
