The ruby, a gemstone synonymous with passion, protection, and prosperity, holds a distinguished place in the world of colored stones. As the birthstone for July, it is a gem deeply embedded in history, lore, and the enduring human fascination with beauty and power. This article will delve into the ruby’s origins, geological formation, historical significance, gemological properties, and enduring symbolism, drawing exclusively from available sources.
History and Lore
The ruby’s story stretches back millennia, captivating civilizations across Asia and Europe. Ancient cultures revered the ruby, often associating it with life force and royalty. In Sanskrit, the finest rubies were known as ratnaraj, meaning “king of precious stones,” a testament to their perceived value and power. Ancient Hindus offered rubies to the god Krishna, hoping for reincarnation as an emperor, highlighting the stone’s connection to leadership and divine favor. This association with royalty extends to other cultures; Burmese warriors believed rubies rendered them invincible in battle, while medieval Europeans attributed to the gem the power to bestow health, wisdom, wealth, and success in love.
The ruby’s historical significance is further underscored by its presence in ancient trade routes. Rubies were traveling along the North Silk Road as early as 200 B.C., and were noted by the scholar Pliny in the first century A.D. Mining activities in Sri Lanka date back to 800 B.C., demonstrating a long-standing appreciation for the gem. The ruby’s fiery hue led to myths surrounding its origin, with some believing it to be the petrified blood of dragons, a vivid tale reflecting its intense color and perceived vitality.
Beyond its association with power and protection, the ruby has also been linked to passion and love. The very name “ruby” derives from the Latin word ruber, meaning “red,” a color universally associated with these emotions. This connection is reflected in the modern tradition of gifting rubies for the 15th and 40th wedding anniversaries, symbolizing enduring love and commitment.
Geological Formation and Sources
The ruby is a variety of the mineral corundum, an aluminum oxide (Al₂O₃) known for its exceptional hardness. Its characteristic red color arises from trace amounts of the element chromium within the crystal structure. The more chromium present, the more intense the red hue. The most prized color is a deep, vibrant red with a hint of purple, often referred to as “pigeon’s blood” within the trade.
Historically, Myanmar (formerly Burma), specifically the Mogok area, has been the most significant source of fine rubies. For over five centuries, Mogok has yielded rubies renowned for their vibrant color, softened by light-scattering inclusions and a distinctive red fluorescence. The region’s unique geological setting, characterized by weathered marble and ancient Buddhist temples, contributes to the exceptional quality of its rubies.
In more recent times, Vietnam has emerged as an important source, particularly the Luc Yen region, known for rubies exhibiting red to purplish-red colors. Mozambique is a newer, prolific source, with rubies from the Montepuez mines often compared to those from Mogok. Other notable ruby-producing regions include Thailand, Cambodia, Afghanistan, Tajikistan, Pakistan, Sri Lanka, Kenya, Tanzania, and Madagascar. Deposits along the border between Thailand and Cambodia were major sources in the late 20th century.
Gemological Properties
Rubies are celebrated not only for their color but also for their exceptional physical properties. They rank 9 on the Mohs scale of hardness, second only to diamonds, making them exceptionally durable and suitable for everyday wear. This hardness contributes to their ability to maintain a polish and resist scratching.
While rubies are primarily known for their red color, variations can occur. The intensity and shade of red are determined by the amount of chromium present, as well as other trace elements. Rubies can range from orangey-red to purplish-red, with the most valuable exhibiting a pure, vibrant red hue. All other colors of corundum are classified as sapphires.
Rubies are typically found in a variety of shapes and sizes, making them versatile for jewelry design. Oval and cushion cuts are popular choices for larger gems, enhancing their natural brilliance. Round and emerald cuts are often used for smaller rubies. The gem’s brilliance can be further enhanced by careful cutting and polishing, maximizing light reflection and refraction.
Here's a table summarizing key gemological properties:
| Property | Value |
|---|---|
| Mineral | Corundum (Al₂O₃) |
| Color | Red |
| Hardness (Mohs) | 9 |
| Luster | Adamantine |
| Specific Gravity | 3.97 – 4.05 |
| Refractive Index | 1.762 – 1.778 |
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 courage. Its association with blood has led to beliefs in its power to protect against misfortune and danger, as well as to cure inflammatory diseases and soothe anger. Some cultures believed the July birthstone color, red, gave it the power of life itself.
In modern times, rubies are often associated with vitality, energy, and motivation. They are believed to stimulate the heart chakra, promoting emotional healing and courage. Some modern interpretations suggest rubies can enhance creativity and inspire passion.
Astrological associations also exist, with rubies linked to the zodiac sign Leo, often referred to as the “king of the zodiac.” For those born between July 1st and 22nd, emerald is considered an alternate birthstone, while onyx is associated with those born between July 23rd and 31st.
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 can be safely cleaned using warm, soapy water and a soft brush. Avoid harsh chemicals or abrasive cleaners, as these can damage the gem’s surface. Ultrasonic cleaners are generally safe for rubies, but caution should be exercised if the ruby contains fractures or has been treated. Regular cleaning will help remove dirt and oils, restoring the ruby’s natural luster.
Conclusion
The ruby stands as a testament to the enduring allure of colored gemstones. From its ancient origins as a symbol of power and royalty to its modern status as July’s vibrant birthstone, the ruby continues to captivate and inspire. Its exceptional hardness, brilliant color, and rich history make it a treasured gem for generations to come. The ruby’s enduring appeal lies not only in its physical beauty but also in the powerful symbolism it embodies – a symbol of passion, courage, and enduring love.
