The ruby, the birthstone of July, is revered not only for its striking beauty but also for its deep historical roots and rich symbolism. Known as the "king of precious stones" in ancient Sanskrit, ruby has captivated humanity for centuries with its vibrant red color and legendary associations with love, vitality, and protection. This article delves into the ruby's gemological properties, historical and cultural significance, geographical sources, and its role in jewelry, particularly in July birthstone rings. Drawing exclusively from the provided sources, we explore how ruby continues to hold a prominent place in both the gemological and cultural worlds.
History and Lore
The ruby, a gemstone of extraordinary allure, has been cherished across civilizations for millennia. In ancient India, ruby was known as ratnaraj, meaning "King of Precious Stones," a title that underscored its esteemed status. It was believed to possess mystical powers and was often worn to protect the wearer from harm and to promote vitality. Ancient Indian texts and traditions associated ruby with the life force, symbolizing youth, strength, and the blood that sustains life.
Burmese warriors, in particular, held a deep reverence for ruby. They believed that wearing a ruby in battle could make them invincible. Some sources suggest that warriors actually embedded rubies into their skin, believing the gem would enhance their physical prowess and courage. This practice, while extreme, reflects the intense faith in ruby’s protective and empowering qualities.
In medieval Europe, ruby was regarded as a gemstone of immense value and significance. It was believed to bestow health, wisdom, wealth, and success in love. Rubies were often set into royal regalia and heirlooms, symbolizing not only status but also divine favor. During the Renaissance, ruby was considered a symbol of Christ’s blood and was often used in religious artifacts and royal insignia.
One of the most famous historical associations of ruby is its mention in the Bible. The ruby is referenced four times in the text, often in the context of wisdom and beauty. In Proverbs 31:10, for example, a noble wife is compared to a ruby, highlighting the stone’s rarity and value. This biblical reference helped cement ruby’s status as a gemstone of divine importance.
In the modern era, ruby remains a symbol of deep emotion and enduring love. It is the traditional birthstone for July and is also associated with the 15th and 40th wedding anniversaries. Its rich red color is often seen as a representation of passion and commitment, making it a popular choice for engagement and anniversary rings.
Geological Formation and Sources
Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). The red color of ruby is due to the presence of trace amounts of the element chromium. The concentration of chromium determines the intensity of the red hue, with the most prized rubies exhibiting a deep, vibrant red with a hint of purple—often referred to in the trade as "pigeon's blood."
The finest rubies in history have been sourced from the Mogok region in Myanmar (formerly Burma). For over 500 years, Mogok has been one of the most renowned sources of high-quality rubies. The area, located in a region of weathered marble and ancient Buddhist temples, is known for producing rubies with a glowing red fluorescence and inclusions that give the stone a unique character.
Vietnam has also become an important source of ruby, particularly in the Luc Yen and Quy Chau districts. These areas produce rubies with a range of red to purplish-red colors. Artisanal miners in these regions work the soil in hopes of uncovering a ruby that could bring them fortune.
In more recent years, Mozambique has emerged as a significant new source of ruby. The Montepuez mines in Mozambique have yielded rubies of exceptional quality, often compared to those from Mogok. These gems are noted for their vivid red color and clarity, making them highly sought after in the global market.
Other notable sources of ruby include Afghanistan, Tajikistan, Pakistan, Sri Lanka, Kenya, Tanzania, and Madagascar. These regions contribute to the global supply of ruby, each producing stones with their own unique characteristics. For example, rubies from Afghanistan tend to have a more purplish tone, while those from Sri Lanka often have a lighter, more orange-red color.
Gemological Properties
The ruby’s gemological properties contribute to its enduring popularity and value. As a variety of corundum, ruby is the second hardest natural gemstone after diamond, with a hardness of 9 on the Mohs scale. This high hardness makes ruby durable and suitable for everyday wear in jewelry.
The refractive index of ruby ranges between 1.76 and 1.78, which gives it a brilliant luster when properly cut and polished. Ruby is also known for its strong pleochroism, meaning it can display different colors when viewed from different angles. This effect is particularly noticeable in rubies with a purplish or orange undertone.
Clarity in ruby can vary, with some stones being nearly flawless while others contain inclusions. These inclusions, often referred to as "silk," are composed of tiny rutile needles that can enhance the stone’s visual appeal by giving it a velvety texture. In the trade, these inclusions are sometimes considered characteristic of a natural ruby rather than a flaw.
Ruby is typically cut into a variety of shapes, including oval, round, cushion, and emerald cuts. The most common cut is the oval, which helps to maximize the stone’s brilliance and minimize the appearance of inclusions. The weight of a ruby is measured in carats, with the most valuable rubies being those that are large and of exceptional color.
Symbolism and Metaphysical Beliefs
Throughout history, ruby has been associated with a range of symbolic meanings and metaphysical properties. In many cultures, it has been seen as a stone of love and passion. Its deep red color is often linked to the heart chakra and is believed to promote emotional healing and vitality. In modern metaphysical practices, ruby is said to enhance courage, confidence, and energy, making it a popular choice for those seeking motivation or protection.
Ancient beliefs about ruby varied by culture but often centered on its protective and empowering qualities. In India, ruby was thought to enable peaceful coexistence with enemies and to bring success in endeavors. In Burma, warriors believed that rubies would grant them invincibility in battle. European royalty and nobles believed that rubies could bestow health, wisdom, and success in love.
In some traditions, ruby was also believed to have healing properties. It was thought to cure inflammatory diseases and soothe anger. These beliefs, while not supported by modern science, reflect the deep cultural and emotional significance that ruby has held across centuries.
Today, ruby is still regarded as a stone of power and passion. It is often chosen for engagement rings, anniversary gifts, and other meaningful jewelry, symbolizing enduring love and commitment. In the world of gemology, ruby remains one of the most coveted and valuable gems, prized not only for its beauty but also for its rich history and symbolism.
Care and Cleaning
Given its hardness and durability, ruby is a relatively easy gemstone to maintain. However, like all natural gemstones, it requires proper care to preserve its beauty and longevity. The following guidelines, drawn from the sources, provide practical advice for cleaning and maintaining ruby jewelry:
Cleaning: Rubies can be cleaned using warm water and mild soap. A soft, damp cloth can be used to gently wipe the stone and remove any dirt or debris. It is important to avoid using harsh chemicals, abrasive materials, or ultrasonic cleaners, as these can potentially damage the gemstone or its setting.
Storage: To prevent scratches and damage, ruby jewelry should be stored separately from other gemstones and jewelry. Soft cloth pouches or individual compartments in a jewelry box are ideal for storing ruby rings, pendants, and other pieces.
Avoiding Chemicals: Ruby should be kept away from perfumes, hairsprays, and other chemicals, as these can dull the stone’s luster over time. It is best to apply such products before putting on ruby jewelry.
Professional Cleaning: For deep cleaning or to restore the gemstone’s brilliance, it is recommended to have ruby jewelry professionally cleaned by a jeweler. This is especially important for pieces with intricate settings or those that have been worn frequently.
Resizing and Repairs: Ruby rings, particularly those with unique or intricate designs, should be resized with caution. As noted in the sources, some rings are not resizable due to the design or the setting of the stone. It is best to have any resizing or repairs performed by a professional jeweler to avoid damaging the stone or the setting.
Metal Considerations: Ruby rings are often set in 14k gold, as highlighted in one of the sources. This type of gold is durable and suitable for everyday wear. It is also important to ensure that the ring is sized correctly by a professional jeweler to avoid issues with fit or comfort.
By following these care and cleaning tips, ruby jewelry can maintain its beauty and value for generations, making it a cherished heirloom or a treasured personal piece.
