Introduction
Ruby, the July 21st birthstone, is a variety of the mineral corundum and is celebrated for its deep red color and exceptional hardness. It has been treasured across cultures and epochs for its beauty and symbolic meaning. While other gemstones like Onyx and Turquoise are also associated with July, Ruby stands out as the most historically and culturally significant. This article explores the origins of Ruby’s use as a birthstone, its geological properties, its symbolic and metaphysical beliefs, and how to care for this precious gem. By examining these facets, we uncover why Ruby remains one of the most coveted gemstones in the world.
History and Lore
Ancient Reverence and Cultural Significance
Ruby has long been regarded as the "king of gemstones" due to its deep red color and historical associations with power and vitality. Its use dates back to ancient times, with civilizations such as the Greeks and Romans attributing magical properties to the gem. The Greeks believed that Rubies protected against poison and danger, while the Romans associated it with the goddess of love, Venus. In ancient India, Ruby was considered the "King of Precious Stones" and was often worn by royalty to ensure good fortune and success in battle.
The name "Ruby" is derived from the Latin word ruber, meaning "red." This vibrant color has made Ruby a symbol of love, courage, and passion in many cultures. In Sanskrit texts, Ruby is referred to as Lalith, and it was believed to bring prosperity and happiness to its wearer. These historical associations have contributed to Ruby’s enduring popularity as a gemstone, especially as a birthstone.
Ruby as a Birthstone
While the exact origins of birthstones are somewhat unclear, many modern lists are based on biblical references, particularly the twelve gemstones mentioned on the High Priest Aaron's breastplate in the Old Testament. Over time, these associations were adapted and expanded to align with the twelve months of the year.
Ruby is the primary birthstone for July, and more specifically, for those born on July 21st. It is also considered a secondary birthstone for other dates in July, alongside Onyx and Turquoise. This triad of gemstones reflects the rich diversity of July’s symbolic and spiritual offerings. However, Ruby’s prominence is due in large part to its rarity, beauty, and the deep cultural significance it carries.
Geological Formation and Sources
The Science Behind Ruby
Ruby is a variety of the mineral corundum, which has the chemical formula Al₂O₃ (aluminum oxide). What distinguishes Ruby from sapphire is the presence of trace amounts of chromium (Cr³⁺), which imparts its signature red color. The intensity of the red hue can vary depending on the concentration of chromium and the presence of other trace elements such as iron.
Ruby has a hardness of 9 on the Mohs scale, making it one of the hardest naturally occurring minerals, second only to diamond. This durability is one of the reasons Ruby has been used in fine jewelry for centuries. Its refractive index ranges from 1.76 to 1.78, and it exhibits strong pleochroism, meaning it can display different colors when viewed from different angles—usually red and deep red or brown.
Ruby typically forms in metamorphic rocks, particularly in marble that has been subjected to high temperatures and pressures. The gemstone is often found in association with other minerals such as corundum, beryl, and tourmaline. The formation of Ruby is a complex process that requires specific geological conditions, which contributes to its rarity.
Major Sources of Ruby
Historically, the most famous source of high-quality Ruby has been the Mogok region in Myanmar (Burma). Known as the "Ruby Valley," this area has produced some of the finest Rubies in the world, including the famous "Pigeon’s Blood" variety. These stones are characterized by their intense red color and high clarity.
Other significant sources of Ruby include:
- India and Sri Lanka: These regions have long been known for their Ruby deposits, though the stones from these areas tend to be more pinkish in hue compared to the deep red of Burmese Rubies.
- Tanzania: A relatively new source of high-quality Ruby, with stones from the Umba region known for their vibrant red to pink color.
- Vietnam and Cambodia: These countries produce Rubies with a range of colors, from deep red to pinkish red.
- Madagascar and Afghanistan: These regions have also become important sources of Ruby in recent decades.
Each of these sources contributes to the global supply of Ruby, but the most prized stones continue to come from Myanmar. The scarcity of high-quality Ruby, combined with its historical and cultural significance, has made it one of the most valuable gemstones in the world.
Gemological Properties
Color and Clarity
Ruby is known for its intense red color, which is caused by the presence of chromium. The most desirable Rubies exhibit a "pigeon’s blood" color—a deep, rich red with a slight blue undertone. This color is particularly associated with Burmese Rubies and is considered the most valuable in the gem trade.
Clarity in Ruby can vary, but the most valuable stones are those with good transparency and minimal inclusions. While some inclusions are natural and can be used to identify a Ruby, excessive inclusions can reduce the stone’s value. The presence of silk-like inclusions, which are fine needle-like structures, is common in Rubies and can enhance the stone’s appearance by creating a soft, velvety sheen.
Cut and Carat
Ruby is typically cut into various shapes, including oval, round, cushion, and emerald cuts. The choice of cut depends on the shape and clarity of the rough stone, as well as the desired aesthetic. The most common cut for Ruby is the oval, which helps to maximize the stone’s color and brilliance.
In terms of carat weight, Ruby is available in a wide range, from small accent stones to large, impressive centerpieces. However, large, high-quality Rubies are extremely rare, and their value increases significantly with size. A 1-carat Ruby in fine quality can be worth several thousand dollars, while a larger, gem-quality Ruby can command a price in the tens of thousands.
Symbolism and Metaphysical Beliefs
Ruby in Ancient and Modern Traditions
Ruby has long been associated with powerful and positive symbolism. In ancient cultures, it was believed to bring protection, strength, and vitality. The gemstone was often worn by warriors and rulers to ensure success in battle and leadership. In medieval Europe, Ruby was considered a symbol of the heart and was used in love charms and talismans.
In modern times, Ruby continues to be associated with love, passion, and energy. It is often given as a gift to celebrate romantic milestones such as anniversaries and engagements. The gemstone is also believed to enhance confidence, courage, and motivation, making it a popular choice for those seeking inspiration and strength.
Metaphysical Properties
Beyond its historical and cultural significance, Ruby is also valued in the world of metaphysical gemstones. It is considered a powerful stone for the heart and root chakras, promoting emotional healing and grounding. Ruby is believed to stimulate the flow of life energy, enhance vitality, and awaken the passion and desire within the individual.
In some traditions, Ruby is also associated with the planet Mars, which governs energy, action, and willpower. This planetary association reinforces its role as a stone of action and determination, making it a popular choice for those seeking to overcome challenges and achieve their goals.
Care and Cleaning
Protecting Ruby’s Beauty
Due to its high hardness and durability, Ruby is a relatively easy gemstone to care for. However, like all gemstones, it requires proper handling and cleaning to maintain its beauty and longevity. Ruby should be cleaned with warm, soapy water and a soft cloth or brush. Avoid using harsh chemicals or ultrasonic cleaners, as these can damage the stone or its setting.
When storing Ruby jewelry, it is best to keep the pieces separate from other gemstones to prevent scratches. Soft cloth pouches or individual compartments in a jewelry box can help protect the stones from contact with other jewelry.
Handling and Wearing
Ruby is suitable for everyday wear, but it should be removed during activities that may cause physical impact or exposure to harsh chemicals. While Ruby is one of the hardest gemstones, it can still be chipped or cracked if subjected to a strong blow or force. Therefore, it is best to remove Ruby jewelry before engaging in strenuous activities such as sports or housework.
