History and Lore
Ruby’s history is as rich and vivid as its color. Known for centuries as the "King of Gemstones," ruby has been cherished by royalty, warriors, and jewelers alike. Its deep red hue was often associated with life force, power, and vitality, making it a prized possession in many ancient societies.
Ancient Beliefs and Cultural Significance
In ancient India, ruby was called the “king of precious stones” due to its rarity, hardness (second only to diamond), and beauty. It was believed to possess mystical properties that could protect the wearer and enhance their vitality. Indian rulers often wore ruby in their jewelry, believing it would grant them courage and success in battle. The gem was also thought to have the power to predict danger or misfortune and even to cure inflammatory diseases and soothe anger.
In Burmese culture, ruby held an even greater significance. Large gemstones were once a monopoly of the Burmese Crown, and Burmese warriors believed that wearing a ruby made them invincible in battle. The gem was so highly valued that it was often set into the hilt of swords or worn in amulets for protection. These beliefs reflect the deep reverence that ruby commanded in ancient times.
The Gemstone of Royalty and Nobility
Throughout history, ruby has been closely associated with royalty. In medieval Europe, ruby was considered one of the most precious stones and was often included in royal regalia. It was believed to bring good fortune, protect against poison, and enhance the wearer’s wisdom and eloquence. Nobles and monarchs would commission ruby-studded crowns, scepters, and rings, not only as symbols of wealth but also as talismans for divine favor.
The gem’s association with power and nobility continued into the modern era. During the 19th century, ruby was still regarded as a stone of exceptional value and beauty. French literature of the time praised ruby as the "lord of gems," emphasizing its deep red color and its perceived divine origin. The Roman philosopher Pliny the Elder theorized that rubies were formed by lightning strikes, giving rise to the German name for ruby, “Donnerkeil,” meaning “thunderbolt.”
Ruby as a Birthstone
The tradition of assigning gemstones to specific months of the year dates back to ancient times, with early references found in biblical and Greek texts. The practice of linking gemstones to months and zodiac signs became more formalized in the 20th century. Ruby was officially recognized as the birthstone for July in 1912 by the American National Retail Jewelers Association and later reaffirmed by the Jewelers of America.
The choice of ruby as July’s birthstone is fitting given its vibrant color and its associations with energy, passion, and vitality. In many cultures, July is a time of growth and renewal, and ruby’s red color symbolizes the warmth of summer and the strength of life.
Geological Formation and Sources
Ruby is a variety of the mineral corundum, which also includes sapphires. While sapphires are typically blue, ruby gets its characteristic red color from trace amounts of the element chromium. The more chromium present, the deeper and more intense the red color becomes. The finest rubies exhibit a deep red with a slight purplish hue, known in the trade as “pigeon’s blood.”
Formation and Composition
Corundum forms under high-pressure and high-temperature conditions, typically in metamorphic rock environments. The presence of chromium during the formation process gives corundum its ruby hue. The chemical formula for ruby is Al₂O₃ (aluminum oxide) with trace amounts of chromium. This composition gives ruby its hardness and durability, making it one of the toughest gemstones after diamond.
Ruby’s hardness is rated at 9 on the Mohs scale, making it suitable for everyday wear in jewelry. Its refractive index ranges between 1.76 and 1.78, contributing to its brilliance and fire. In terms of clarity, rubies can vary from eye-clean to containing inclusions, which are natural features formed during the gem’s growth. These inclusions are often referred to as “silk” and can enhance the gem’s beauty and value.
Major Sources
Historically, Burma (now Myanmar) was the primary source of high-quality rubies. The Mogok region in central Myanmar has been known for producing some of the finest rubies in the world, particularly those with the coveted “pigeon’s blood” color. These rubies were once a monopoly of the Burmese Crown and were highly prized for their exceptional color and clarity.
Other notable sources of ruby include Thailand, Sri Lanka, and Madagascar. In recent decades, rubies have also been found in Afghanistan, Vietnam, and Tanzania. While these sources can produce high-quality stones, the finest rubies with the richest color and clarity are still considered to come from Myanmar.
The mining and trade of rubies have been subject to ethical and environmental concerns. Due to the gem’s high value and the remote locations of many ruby deposits, the industry has faced criticism for labor practices and environmental impact. Ethical sourcing and transparency have become increasingly important in the ruby trade.
Gemological Properties
Understanding the gemological properties of ruby is essential for appreciating its value and beauty. Ruby’s unique characteristics, including its color, hardness, and durability, make it one of the most desirable gemstones in the world.
Color and Clarity
The most distinguishing feature of ruby is its rich red color. The term “pigeon’s blood” refers to the finest ruby color, characterized by a deep red with a slight purplish hue. This color is caused by the presence of chromium in the gem. The intensity of the red color depends on the concentration of chromium, with higher concentrations producing a more vibrant hue.
Clarity in ruby can vary. Some rubies are nearly eye-clean, while others contain inclusions that are visible to the naked eye. These inclusions are natural features and can add character to the gem. In some cases, inclusions can also affect the gem’s durability, so it is important to consider the cut and setting when designing ruby jewelry.
Hardness and Durability
Ruby ranks 9 on the Mohs scale of hardness, just below diamond. This high hardness makes ruby one of the most durable gemstones, suitable for use in a variety of jewelry settings. Despite its hardness, ruby can be brittle and may have cleavage, which means it can be fractured under the right angle of impact. Therefore, ruby should be handled with care, especially in jewelry that is worn frequently.
Ruby’s durability also depends on its treatment. Many rubies undergo heat treatment to enhance their color and clarity. While this treatment is widely accepted in the gemstone industry, it is important for consumers to be aware of any treatments when purchasing ruby jewelry.
Symbolism and Metaphysical Beliefs
Ruby has been associated with a wide range of symbolic meanings and metaphysical properties across cultures and historical periods. Its deep red color has made it a symbol of life, love, and vitality, while its rarity and beauty have contributed to its status as a gemstone of power and protection.
Emotional and Spiritual Symbolism
Ruby is often linked to emotions such as love, passion, and courage. In many cultures, ruby was believed to enhance the wearer’s vitality and energy, making it a popular choice for those seeking to boost their confidence and strength. It was also associated with the heart chakra, believed to promote emotional balance and healing.
The gemstone was also thought to enhance one’s ability to communicate effectively and express emotions. In medieval Europe, ruby was believed to grant the wearer eloquence and wisdom, making it a popular choice for nobles and scholars.
Protective and Healing Properties
Ruby has long been considered a protective gemstone. In ancient times, warriors believed that wearing a ruby would make them invincible in battle. It was also thought to protect the wearer from poison, disease, and misfortune. Some cultures believed that ruby could predict danger or misfortune, acting as a warning to the wearer.
In traditional medicine, ruby was believed to have healing properties, particularly in treating inflammatory conditions and calming anger. Some sources suggest that ruby could help soothe the mind and promote a sense of calm and well-being.
Ruby in Modern Metaphysical Beliefs
While the scientific community does not support the metaphysical properties of gemstones, many modern practitioners and crystal healers continue to use ruby for its symbolic and energetic properties. Ruby is often recommended for those seeking to enhance their vitality, confidence, and emotional resilience. It is also used in meditation and spiritual practices to promote courage and strength.
Care and Cleaning
Due to its high hardness and durability, ruby is a suitable gemstone for everyday wear. However, to maintain its beauty and longevity, it is important to care for ruby jewelry properly.
Cleaning Methods
Ruby can be cleaned using mild soap and warm water. A soft brush can be used to gently remove dirt and debris from the gem’s surface. It is important to avoid harsh chemicals or abrasive cleaners, as these can damage the gem or its setting.
Ultrasonic and steam cleaners can also be used for ruby, but it is recommended to consult a professional jeweler before using these methods, especially if the gem has inclusions or has been treated.
Storage and Handling
When not in use, ruby jewelry should be stored in a soft, lined jewelry box to prevent scratches and damage. It is also advisable to store ruby separately from other gemstones, as even the hardest stones can cause scratches over time.
When handling ruby jewelry, it is important to avoid dropping it or exposing it to sudden temperature changes, as this can cause the gem to fracture. It is also advisable to remove ruby jewelry before engaging in activities that could cause impact or abrasion.
