The ruby, a gemstone steeped in history and revered for its vibrant red hue, holds the distinction of being the July birthstone. Symbolizing passion, love, and vitality, this captivating gem has captivated civilizations for millennia. Its rich color, exceptional durability, and historical associations with power and protection have cemented its status as one of the most coveted gemstones in the world. This article will delve into the ruby’s history, geological origins, gemological properties, symbolism, and care, drawing exclusively from available sources.
History and Lore
Rubies boast a history stretching back to ancient times, with evidence of their use and admiration found in numerous cultures. In ancient India, the ruby was known as the “king of precious stones,” prized for its rarity, hardness – second only to diamond – beauty, and perceived mystical powers. It was believed to possess the power to protect against misfortune and danger, and was often embedded in the armor of Burmese warriors, who believed it rendered them invincible in battle.
Medieval Europeans also held rubies in high esteem, attributing to them the ability to bestow health, wisdom, wealth, and success in love. The gem’s association with blood, the life force, further enhanced its symbolic power, representing vitality and youthful energy. Royal families worldwide have long prized rubies as emblems of power and wealth, adorning themselves with the gem to reflect their status. Beyond its association with royalty and warriors, the ruby was also believed to have healing properties, with some claiming it could cure inflammatory diseases and soothe anger.
The ruby’s significance extends beyond mere adornment; it is traditionally given to celebrate both the 15th and 40th wedding anniversaries, symbolizing enduring passion and commitment. This tradition underscores the ruby’s enduring association with love and lasting relationships.
Geological Formation and Sources
Rubies are a variety of the mineral corundum, an aluminum oxide mineral. Their characteristic red color arises from trace amounts of the element chromium present within the crystal structure. The more chromium present, the stronger and more vivid the red coloration. The presence of chromium also causes rubies to fluoresce under ultraviolet light, creating a distinctive glow that enhances their beauty and value, sometimes visible even in daylight.
While corundum crystals are naturally colorless, the introduction of chromium during their formation transforms them into the prized ruby. The formation of rubies requires specific geological conditions, typically occurring in metamorphic or magmatic environments.
Source materials indicate that rubies are found in various locations around the world, with Myanmar (formerly Burma) historically being the most significant source.
Gemological Properties
The ruby’s appeal lies not only in its color but also in its exceptional physical properties. It registers a 9 on the Mohs hardness scale, making it exceptionally durable and suitable for everyday wear. This hardness is surpassed only by diamond.
The ideal ruby color is a deep, vivid red with a slight hint of purple, a shade often referred to as “pigeon’s blood” in the trade. However, rubies exhibit a range of red hues, from pinkish reds to bold magentas, depending on the concentration and distribution of chromium.
The quality of a ruby’s color is determined by three key factors: hue, tone, and saturation. The most valuable rubies display a pure red hue, a medium to medium-dark tone, and vivid saturation. While a pure red hue is preferred, some purple, pink, or orange undertones are acceptable in fine rubies.
Rubies exceeding one carat in size are considered relatively rare, and prices increase dramatically with carat weight. Exceptional large rubies command premium prices in the market.
Here's a table summarizing key gemological properties:
| Property | Value |
|---|---|
| Mineral | Corundum |
| Chemical Formula | Al₂O₃ |
| Hardness (Mohs) | 9 |
| Color | Red |
| Luster | Adamantine |
| Fluorescence | Often present |
Symbolism and Metaphysical Beliefs
Throughout history, the color red has held profound symbolic meaning across cultures, representing blood, life, and vitality. As the quintessential red gemstone, the ruby has come to symbolize powerful concepts such as strength, protection, healing, and royal status.
Ancient Hindus believed that offering rubies to the god Krishna would result in reincarnation as emperors, highlighting the gem’s association with power and divine favor. The ruby was also thought to promote healing and recovery, with soldiers hoping its red power would aid in overcoming injuries.
Beyond its historical and cultural symbolism, rubies are also associated with emotional qualities. They represent passion, love, and commitment, making them popular choices for engagement rings and anniversary gifts.
Care and Cleaning
Due to its exceptional hardness, the ruby is a relatively durable gemstone. However, like all gemstones, it requires proper care to maintain its brilliance and beauty. Rubies can be safely cleaned using warm, soapy water and a soft brush. Avoid harsh chemicals or abrasive cleaners, as these can damage the stone’s surface.
While rubies are resistant to scratching, they are susceptible to chipping if subjected to a sharp blow. It is advisable to remove ruby jewelry before engaging in strenuous activities or when handling abrasive materials. Regular cleaning and careful handling will ensure that a ruby continues to sparkle for generations.
Alternative Birthstones
While ruby is the traditional July birthstone, garnet and citrine are recognized as alternative birthstones for those born in this month. Garnets, available in a variety of colors including red, green, orange, and yellow, are associated with history, security, and might. They are believed to evoke passion, improve creativity, and offer a form of spirituality. Garnets typically have a Mohs hardness of 6.5 to 7.
Conclusion
The ruby, with its captivating red hue and rich history, remains a highly prized and symbolic gemstone. From its ancient origins as a symbol of power and protection to its modern association with love and passion, the ruby continues to fascinate and inspire. Its exceptional durability, combined with its stunning beauty, ensures its enduring appeal for generations to come. As the July birthstone, the ruby embodies the vibrancy and energy of the summer season, making it a truly remarkable and cherished gem.
