The ruby, a gemstone steeped in history and symbolism, holds a prominent position as a July birthstone, particularly resonant with those born under the sign of Cancer. Revered for its captivating red hue and association with passion, vitality, and courage, the ruby has captivated civilizations for centuries. While July also encompasses the astrological sign of Leo, for whom peridot is a celebrated birthstone, the ruby maintains a strong connection to those born within the earlier portion of the month, specifically those falling under the Cancer zodiac. This article will delve into the ruby’s historical significance, geological origins, gemological properties, cultural symbolism, and considerations for its care.
History and Lore
The ruby’s history is a long and vibrant one, stretching back millennia. The very name “ruby” originates from the Latin word ruber, meaning red, a testament to the gem’s most defining characteristic. For over five centuries, the Mogok area of Myanmar (Burma) has been a primary source of highly prized rubies, renowned for their exceptional color and clarity. Vietnam also boasts significant ruby deposits, and more recently, Mozambique, Afghanistan, Tajikistan, Pakistan, Sri Lanka, Kenya, Tanzania, and Madagascar have emerged as important sources.
Ancient cultures attributed numerous powers to the ruby. Some believed it possessed protective qualities, warding off evil and ensuring health and prosperity. In ancient times, people thought that Carnelian connects to the sacral chakra, which is responsible for boosting a person’s self-confidence. It is also empowering and stimulating. Hindu mythology even associates moonstone with solidified moonbeams, highlighting the mystical reverence surrounding gemstones. Ancient Incas utilized emeralds, another gem sometimes associated with July, in religious ceremonies for centuries. The ruby’s association with royalty and power is also deeply rooted in history, often adorning crowns and jewelry of kings and queens.
Geological Formation and Sources
Rubies are a variety of the mineral corundum (aluminum oxide). Their characteristic red color is derived from the presence of the element chromium. The intensity of the red hue is directly proportional to the amount of chromium present; the most desirable rubies exhibit a deep, vivid red, sometimes with hints of purple, often referred to as “pigeon’s blood.”
The formation of rubies is a complex geological process, typically occurring in metamorphic rocks. These gems are formed under conditions of intense heat and pressure, often associated with the collision of tectonic plates. The ruby crystals grow slowly over time, requiring specific geological conditions to develop their characteristic color and clarity.
As previously mentioned, Myanmar’s Mogok area has historically been the most significant source of high-quality rubies. However, in recent years, Mozambique has become a major producer, yielding rubies that rival those from Myanmar in color and clarity. Other notable sources include Vietnam, Afghanistan, Tajikistan, Pakistan, Sri Lanka, Kenya, Tanzania, and Madagascar.
Gemological Properties
The ruby possesses a unique set of gemological properties that contribute to its value and desirability.
| Property | Value |
|---|---|
| Chemical Formula | Al₂O₃ |
| Hardness (Mohs) | 9 |
| Refractive Index | 1.762 – 1.778 |
| Specific Gravity | 3.97 – 4.05 |
| Crystal System | Trigonal |
| Color | Red |
The ruby’s hardness of 9 on the Mohs scale makes it exceptionally durable, second only to diamond. This durability makes it suitable for everyday wear in jewelry. The refractive index, ranging from 1.762 to 1.778, contributes to the ruby’s brilliance and fire. The specific gravity, between 3.97 and 4.05, is relatively high, giving the stone a substantial feel.
Inclusions, or internal imperfections, are common in rubies. While excessive inclusions can detract from a ruby’s clarity and value, some inclusions can serve as a “fingerprint,” confirming the gem’s natural origin. The structure of rubies is hexagonal.
Symbolism and Metaphysical Beliefs
Throughout history, the ruby has been imbued with rich symbolism. It is widely regarded as a symbol of love, passion, and courage. The deep red color is often associated with the heart and emotions, representing intense feelings and vitality. Rubies are also believed to promote strength, energy, and protection.
For those born under the Cancer zodiac sign (June 21st to July 22nd), the ruby is considered a primary birthstone. It is believed to harmonize with Cancer’s sensitive and nurturing nature, bringing balance and emotional strength. The ruby’s fiery energy is thought to counteract Cancer’s tendency towards moodiness, fostering confidence and resilience. Carnelian, with its fiery orange energy, is also believed to have a grounding effect on Cancer, boosting motivation and creativity. Moonstone, the traditional gemstone for Cancer, strengthens intuition and balances emotions.
The ruby is also associated with celebrity and status, often worn by those in positions of power and influence. It is believed to inspire leadership qualities and attract success.
Care and Cleaning
Due to its exceptional hardness, the ruby is a relatively durable gemstone. However, proper care is essential to maintain its brilliance and beauty. Rubies should be cleaned regularly with warm, soapy water and a soft brush. Avoid harsh chemicals, ultrasonic cleaners, and steam cleaners, as these can damage the stone.
It is also important to protect rubies from scratches and impacts. While highly durable, a sharp blow can still cause chipping or fracturing. Store rubies separately from other jewelry to prevent scratches. Regular inspection of settings is recommended to ensure the ruby is securely mounted.
Conclusion
The ruby stands as a testament to the enduring allure of gemstones. Its rich history, captivating color, and potent symbolism have cemented its place as a treasured gem for centuries. As the birthstone for July, and particularly resonant with those born under the Cancer zodiac, the ruby embodies passion, vitality, and courage. Its durability and brilliance ensure it will continue to be cherished and admired for generations to come. The ruby is more than just a beautiful stone; it is a symbol of love, strength, and the enduring power of nature.
