Whether you are a gemstone enthusiast, a jewelry buyer, or simply curious about the July birthstone, this article will provide a comprehensive overview of ruby's enduring appeal.
History and Lore
Ruby has captivated human imagination for centuries, often associated with power, passion, and protection. In ancient India, ruby was known as "ratnaraj," meaning "king of precious stones," a title that reflects its esteemed status. The gemstone's deep red color was linked to the life force of blood and was believed to bring vitality and energy to the wearer. Indian royalty and warriors adorned themselves with ruby, believing it would grant them invincibility in battle.
In medieval Europe, ruby was thought to possess miraculous properties. It was believed to predict danger, cure inflammatory diseases, and bring wisdom, health, and success in love. Some historical accounts suggest that rubies were embedded in the armor of knights and warriors to provide protection and courage. The gemstone was also associated with the sun, symbolizing warmth, strength, and regal authority.
In Burmese culture, ruby was considered a symbol of prosperity and good fortune. Burmese warriors believed that carrying a ruby would make them invincible, and the gemstone was often included in royal regalia. The association between ruby and royalty continued through the centuries, with many monarchs incorporating rubies into their crowns and jewelry.
The modern designation of ruby as the July birthstone was officially recognized in the 1950s by the Jewelers of America. However, ruby has long been a traditional birthstone for the month, with its significance dating back to ancient times. The gemstone's enduring appeal is reflected in its continued use in high-end jewelry and its designation as a symbol for the 15th and 40th wedding anniversaries.
Geological Formation and Sources
Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). The gemstone's distinctive red color is due to the presence of trace amounts of chromium, which imparts a deep red hue. The most prized rubies exhibit a color known as "pigeon's blood," a term used in the trade to describe a vivid red with a slight purplish undertone. The amount of chromium in the stone determines the intensity of the red color, with higher chromium content resulting in a stronger hue.
Rubies are formed deep within the Earth's crust under high-pressure and high-temperature conditions. They typically occur in metamorphic rocks, such as marble, and are often found in association with other gemstones like sapphires. The geological processes that form ruby are complex and require specific conditions to produce the gemstone's characteristic color and clarity.
Myanmar (formerly Burma) is the most famous source of high-quality rubies. The Mogok region in northern Myanmar has been a renowned ruby-producing area for over 500 years. The rubies from this region are known for their exceptional color and are considered some of the finest in the world. In addition to Myanmar, ruby deposits have been found in several other countries, including Thailand, Vietnam, Cambodia, and Sri Lanka. Each of these regions produces rubies with slightly different characteristics, influenced by the local geology and trace elements.
In Vietnam, ruby deposits are found in the northern regions, where the gemstones are known for their deep red to purplish-red hues. Thai rubies, particularly those from the Chanthaburi region, are also highly valued, though they often have a slightly different coloration due to variations in the mineral composition. These global sources contribute to the diverse availability of ruby, allowing for a range of colors and qualities in the gemstone market.
Gemological Properties
Ruby is one of the hardest gemstones, second only to diamond on the Mohs scale of mineral hardness. With a hardness rating of 9, ruby is highly durable and resistant to scratches, making it an excellent choice for everyday jewelry. However, it is important to note that ruby can have cleavage planes, which are natural weaknesses in the crystal structure. These cleavage planes can make the gemstone more susceptible to chipping if struck in the wrong direction.
In terms of refractive index, ruby typically ranges between 1.76 and 1.78, which contributes to its brilliance and fire. The gemstone's refractive properties, combined with its deep red color, create a captivating visual effect that enhances its beauty. Ruby is also known for its pleochroism, a phenomenon in which the gemstone can display different colors when viewed from different angles. This property is particularly noticeable in rubies with higher chromium content.
The clarity of ruby can vary, with some specimens exhibiting excellent transparency and others containing inclusions that are visible to the naked eye. Inclusions in ruby are often referred to as "silk," and they can contribute to the gemstone's character and value. In some cases, inclusions are considered desirable as they can indicate the natural origin of the ruby and provide insight into its geological history.
Ruby is available in a range of sizes, from small melee stones used in jewelry settings to large, faceted gems that can weigh several carats. The carat weight of a ruby significantly impacts its value, with larger stones being rarer and more valuable. However, the color and quality of the ruby are equally important factors in determining its worth.
Symbolism and Metaphysical Beliefs
Throughout history, ruby has been associated with a wide range of symbolic meanings and metaphysical properties. In many cultures, ruby is considered a stone of passion, love, and vitality. Its deep red color is often linked to the heart and is believed to enhance emotional well-being and strengthen relationships. Ruby is thought to stimulate the heart chakra, promoting love, compassion, and emotional healing.
In addition to its associations with love, ruby is also regarded as a protective stone. Ancient cultures believed that wearing a ruby could shield the wearer from harm and bring good fortune. This protective quality was particularly valued by warriors and royalty, who often incorporated rubies into their armor and regalia. Some historical accounts suggest that rubies were used as talismans to ward off evil spirits and negative energies.
Ruby is also associated with courage and confidence. It is believed to instill a sense of strength and determination in the wearer, helping them to overcome challenges and pursue their goals. This property makes ruby a popular choice for those seeking motivation and inspiration. The gemstone is also thought to enhance vitality and energy, making it a symbol of youth and vigor.
In modern times, ruby continues to be cherished for its symbolic significance. It is often given as a gift to celebrate love, friendship, and important milestones. The gemstone's enduring appeal is reflected in its use in engagement rings, wedding bands, and other meaningful jewelry pieces. Whether worn for its beauty or its symbolic meaning, ruby remains a powerful and captivating gemstone.
Care and Cleaning
Due to its high hardness and durability, ruby is well-suited for everyday wear. However, proper care and maintenance are essential to preserve its beauty and longevity. Ruby should be cleaned regularly to remove dirt, oils, and other debris that can dull its appearance. A gentle cleaning solution of warm water and mild dish soap is typically effective for cleaning ruby. The gemstone should be soaked in the solution for a few minutes before being rinsed with lukewarm water and dried with a soft, lint-free cloth.
It is important to avoid using harsh chemicals, abrasive materials, or ultrasonic cleaners when cleaning ruby, as these can damage the gemstone or its setting. Ultrasonic cleaners may not be suitable for rubies with certain inclusions or treatments, as the vibrations can potentially cause micro-fractures or damage to the stone. Similarly, steam cleaners should be used with caution, as the high heat can be detrimental to the gemstone.
When storing ruby jewelry, it is advisable to keep the pieces in a soft, padded container or a separate compartment to prevent scratches and abrasions. Ruby should be stored away from harder gemstones like diamonds, which can cause scratches if they come into contact. Additionally, it is important to avoid exposing ruby to extreme temperatures or sudden temperature changes, as this can cause the gemstone to crack or become damaged.
For more extensive cleaning or repairs, it is recommended to consult a professional jeweler who specializes in gemstone care. A jeweler can perform a thorough inspection of the ruby and its setting, checking for any loose stones, bent prongs, or other issues that may require repair. Regular maintenance, including inspections and cleanings, can help ensure that ruby jewelry remains in excellent condition for years to come.
