For centuries, the ruby has captivated humanity with its fiery brilliance and rich symbolism. As the traditional birthstone for July, this gemstone embodies passion, protection, and prosperity. Its deep red hue, often described as “pigeon’s blood” when possessing the most desirable shade, has linked it to royalty, courage, and enduring love across numerous cultures. This article delves into the history, geological origins, gemological properties, and cultural significance of the ruby, offering a comprehensive overview of this remarkable gem.
History and Lore
The ruby’s history is deeply intertwined with ancient civilizations. In ancient India, the ruby was revered as the “king of precious stones,” known as ratnaraj in Sanskrit. This title reflected not only its rarity and beauty but also the perceived mystical powers attributed to it. Rubies were offered to the god Krishna, with the hope of reincarnation as an emperor, highlighting the stone’s association with power and status.
Ancient Hindus believed rubies held the power to protect against misfortune and even cure inflammatory diseases, while Burmese warriors inserted rubies under their skin, believing they rendered them invincible in battle. Medieval Europeans similarly ascribed protective qualities to the ruby, believing it bestowed health, wisdom, wealth, and success in love. The association with life force, stemming from its blood-red color, was prevalent in many early cultures.
The ruby’s connection to royalty extends beyond ancient times. Throughout history, rubies have adorned the crowns and jewelry of kings and queens, symbolizing their power and authority. Today, the ruby remains the traditional gift for the 15th and 40th wedding anniversaries, signifying enduring passion and commitment.
Geological Formation and Sources
Rubies are a variety of the mineral corundum, an aluminum oxide (Al₂O₃) mineral. Their characteristic red color arises from trace amounts of the element chromium present during the stone’s formation. The more chromium present, the more intense the red hue.
Rubies form in metamorphic and igneous rocks. Metamorphic rubies are created when existing rocks are subjected to intense heat and pressure, while igneous rubies crystallize from magma. These conditions are relatively rare, contributing to the ruby’s scarcity and value.
While rubies have been sourced from various locations globally, certain regions are particularly renowned for their production. Historically, Burma (now Myanmar) was considered the source of the finest rubies, particularly those exhibiting the coveted “pigeon’s blood” color. Other significant sources include Thailand, Sri Lanka, and more recently, Mozambique and Madagascar.
Gemological Properties
The ruby’s exceptional qualities make it a highly prized gemstone. Its hardness, ranking 9 on the Mohs scale (second only to diamond), ensures durability and resistance to scratching, making it suitable for everyday wear.
Here's a summary of key gemological properties:
| Property | Description |
|---|---|
| Mineral | Corundum (Aluminum Oxide) |
| Chemical Formula | Al₂O₃ |
| Color | Red (varying shades, best is “pigeon’s blood”) |
| Hardness (Mohs) | 9 |
| Luster | Vitreous (glass-like) |
| Crystal System | Trigonal |
| Refractive Index | 1.762 – 1.778 |
The name “ruby” itself originates from the Latin word ruber, meaning “red.” The most desirable rubies exhibit a vibrant, pure red color with a slight hint of purple, known as “pigeon’s blood.” However, rubies can also occur in shades of pinkish-red, orangish-red, and even brownish-red. Clarity also plays a role in a ruby’s value, with fewer inclusions generally commanding higher prices.
Symbolism and Metaphysical Beliefs
Throughout history, the ruby has been imbued with a wealth of symbolic meaning. As previously mentioned, it represents passion, love, and vitality. Its association with blood has also linked it to courage, energy, and life force.
In some cultures, the ruby was believed to possess protective powers, warding off evil and ensuring safety during travel. Others attributed the ability to predict misfortune or danger to the stone. Beyond protection, rubies were thought to promote good health, wisdom, and success in love.
The connection to the zodiac sign Leo, one of the sun signs affiliated with July, further reinforces the ruby’s association with royalty and leadership. The ruby is often seen as a stone of empowerment, inspiring confidence and encouraging action.
Wearing and Caring for Rubies
Rubies are versatile gemstones suitable for a wide range of jewelry styles. They are frequently featured in rings, earrings, bracelets, and necklaces. Modern designs often incorporate rubies alongside diamonds, creating stunning and sophisticated pieces. Roberto Coin, for example, crafts ruby and diamond bangles with a playful elegance.
Due to their hardness, rubies are relatively durable, but they still require proper care to maintain their brilliance. It is recommended to clean rubies with warm, soapy water and a soft brush. Avoid harsh chemicals, ultrasonic cleaners, and steam cleaners, as these can damage the stone. Storing rubies separately from other jewelry will prevent scratches. Regular inspection of settings is also advisable to ensure the ruby remains securely mounted.
Conclusion
The ruby stands as a testament to the enduring allure of gemstones. From its ancient origins as a symbol of power and protection to its modern status as a coveted birthstone and jewelry staple, the ruby continues to captivate and inspire. Its vibrant color, exceptional durability, and rich history make it a truly remarkable gem, worthy of its title as the “king of precious stones.” For those born in July, or simply drawn to its fiery beauty, the ruby offers a timeless connection to passion, prosperity, and enduring love.
