This article explores the ruby as the July birthstone in detail, covering its historical significance, geological properties, cultural symbolism, and care instructions.
July is unique in that it has two traditional birthstones—ruby and onyx—but ruby is the most widely recognized and celebrated of the two. This vibrant gemstone has captivated civilizations for centuries, symbolizing passion, power, and protection. Its rarity and brilliance make it one of the most valuable gemstones in the world.
The ruby’s name is derived from the Latin word ruber, meaning “red.” This fiery hue is not just visually striking but also deeply symbolic, representing love, vitality, and energy. Rubies are among the most sought-after gems due to their combination of beauty, rarity, and historical prestige.
This article will explore the ruby in depth, covering its geological formation, historical and cultural significance, gemological properties, and practical care tips. It will also touch on the ruby’s role as both a modern and traditional birthstone and its use in jewelry and spiritual practices.
History and Lore
The ruby has a storied history that dates back thousands of years. Ancient civilizations revered it for its beauty and believed it possessed mystical powers. In ancient India, ruby was known as ratnaraj, meaning "king of precious stones." It was considered a symbol of power, vitality, and protection. Indian royalty often adorned themselves with rubies, believing they brought good fortune and ensured a long and prosperous life.
In Medieval Europe, rubies were associated with health, wisdom, wealth, and success in love. Some believed that these gems could predict misfortune or danger, while others claimed they could cure inflammatory diseases and soothe anger. These beliefs were passed down through generations and contributed to the ruby's enduring popularity.
Burmese warriors, in particular, believed that wearing a ruby in battle made them invincible. This belief was rooted in the stone's vibrant red color, which was associated with life and vitality. Rubies were often worn as talismans, thought to provide protection and strength in times of conflict.
The ruby's association with royalty and power is also evident in various cultures. In ancient Hindu traditions, rubies were offered to the god Krishna in hopes of being reincarnated as an emperor. This practice reflected the belief that the ruby had the power to elevate one's status and bring divine favor.
In modern times, the ruby has been designated as the official birthstone for July by the Jewelers of America in the 1950s. It is also a traditional birthstone, with roots in ancient Greek and Roman philosophies. The ruby’s enduring appeal is due in part to its rich history and the many meanings attributed to it across different cultures.
Geological Formation and Sources
Rubies are a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). What sets rubies apart from other corundum varieties, such as sapphires, is the trace element chromium, which gives them their distinctive red color. The more chromium present, the stronger the red hue. The finest rubies are known as "pigeon's blood" rubies, characterized by a deep red with a hint of purple.
The formation of rubies occurs under extreme heat and pressure deep within the Earth's crust. They are typically found in metamorphic rocks, where they form in association with other gemstones like sapphires and emeralds. Over millions of years, these gemstones are brought to the surface through geological processes such as tectonic activity and volcanic eruptions.
Rubies are primarily found in a few key locations around the world. Myanmar (formerly Burma) is the most famous source of high-quality rubies, particularly the "pigeon's blood" variety. Other notable ruby-producing regions include Thailand, Sri Lanka, Afghanistan, Tanzania, and Vietnam. Each of these locations produces rubies with slightly different characteristics, influenced by the local geology and mineral composition.
The rarity of high-quality rubies contributes to their value. Only a small percentage of corundum crystals contain enough chromium to qualify as rubies, and even fewer meet the criteria for top-grade gems. This scarcity, combined with their beauty and historical significance, makes rubies one of the most valuable gemstones in the world.
Gemological Properties
Rubies are among the hardest gemstones, ranking 9 on the Mohs scale of mineral hardness. This high hardness makes them durable and suitable for everyday wear, although they can still be scratched by diamonds and other gems with the same or higher hardness. Their toughness is also notable, as they are resistant to chipping and breaking, though they can have cleavage planes that make them vulnerable to fractures under certain conditions.
The refractive index of ruby ranges from 1.76 to 1.78, giving it a brilliant luster when cut and polished. This luster, combined with its deep red color, makes ruby one of the most visually striking gemstones. The finest rubies exhibit a "pigeon's blood" color, which is a vivid red with a slight purplish undertone. This color is highly sought after and can command premium prices in the market.
Ruby is a uniaxial gemstone, meaning it has one optic axis. This property affects how light travels through the stone, contributing to its unique optical characteristics. The presence of inclusions, or internal features, is common in rubies and can help gemologists identify their origin. These inclusions are often referred to as "silk" and can enhance the stone's beauty by giving it a velvety appearance.
The carat weight of a ruby significantly affects its value. Larger rubies are rarer and more valuable, especially if they are of high quality. A ruby weighing just one carat can be worth thousands of dollars, depending on its color, clarity, and origin. The most valuable rubies are those that are large, of high quality, and from renowned sources like Myanmar.
Symbolism and Metaphysical Beliefs
Throughout history, rubies have been attributed with various symbolic and metaphysical properties. In many cultures, they are seen as symbols of love, passion, and vitality. The ruby’s deep red color is often associated with the life force and is believed to bring energy and warmth to those who wear it.
In ancient times, rubies were thought to have protective qualities. They were often used as talismans to ward off evil and bring good fortune. Some believed that rubies could predict danger or misfortune, serving as a warning to those who wore them. Others claimed that rubies had healing properties, particularly for blood-related ailments, due to their red color and association with life.
The ruby is also a symbol of power and strength. In ancient India, it was believed to grant the wearer the ability to rule and make wise decisions. This belief was reflected in the stone's association with royalty, as it was often worn by kings and emperors to signify their authority and divine favor.
Modern metaphysical beliefs also attribute certain properties to rubies. They are said to enhance confidence, stimulate courage, and promote a sense of well-being. Rubies are often used in meditation and energy healing practices to open the heart chakra and encourage emotional balance.
Care and Cleaning
Proper care and cleaning are essential for maintaining the beauty and longevity of a ruby. While rubies are durable, they can still be damaged by harsh chemicals, extreme temperatures, and physical impacts. To keep a ruby in excellent condition, it is recommended to avoid exposing it to abrasive materials, which can scratch its surface.
Cleaning a ruby can be done using a soft cloth and a mild detergent. A soft-bristled brush can be used to gently remove dirt and debris from the stone. It is important to rinse the gem thoroughly with water and dry it with a clean cloth to prevent any residue from remaining on its surface.
For more thorough cleaning, a professional jeweler can use an ultrasonic cleaner or steam cleaner. These methods are effective in removing stubborn dirt and grime without damaging the gemstone. However, it is important to consult with a professional before using these methods, as some rubies may have treatments or inclusions that could be affected by the cleaning process.
When storing a ruby, it is best to keep it in a soft pouch or a lined jewelry box to prevent scratches and damage. Rubies should also be kept away from direct sunlight and extreme temperatures to avoid any potential discoloration or structural damage.
