History and Lore
The ruby has a storied history that spans millennia, with evidence of its use in ancient civilizations such as Egypt, India, and China. Known as the "king of gemstones," ruby has been revered for its beauty, rarity, and symbolic power. In ancient India, ruby was believed to bring good fortune and protection, and it was often worn by royalty and warriors. The gem was thought to possess divine properties and was considered a talisman of courage and strength.
In medieval Europe, ruby was associated with the blood of Christ and was used in religious and royal jewelry. It was believed to protect the wearer from harm and to bring vitality and energy. During the Renaissance, ruby jewelry became a symbol of wealth and status, with European nobles commissioning elaborate ruby pieces for their courts.
The ruby’s association with love and passion has also endured through the centuries. In ancient Greece and Rome, ruby was believed to stimulate the heart and promote romantic feelings. It was often given as a token of love, much like diamond rings are today. In many cultures, ruby has also been considered a gem of protection, warding off evil spirits and bringing good fortune.
As the birthstone for July, ruby continues to carry this rich legacy of symbolism and meaning. It represents not only the fiery energy and passion of those born in July but also the enduring strength and courage that ruby has always been associated with.
Geological Formation and Sources
Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). What distinguishes ruby from other corundum varieties, such as sapphire, is the presence of chromium, which gives ruby its characteristic red color. The most prized rubies exhibit a deep, intense red hue known as "pigeon blood red," a term used to describe the rarest and most valuable ruby coloration.
Rubies form under intense heat and pressure deep within the Earth’s crust, typically in metamorphic rock environments. They are often found in association with marble and other metamorphic rocks that have been subjected to high temperatures and pressures. Over time, these conditions cause the aluminum oxide to crystallize into corundum, with trace amounts of chromium giving the gem its red color.
The most famous ruby-producing regions in the world include:
- Myanmar (Burma): Known for producing the finest "pigeon blood red" rubies, Myanmar has been a major source of high-quality ruby for centuries. The rubies from this region are highly sought after for their vivid color and exceptional clarity.
- Madagascar: Madagascar is another significant ruby producer, with rubies that often display a slightly lighter, more pinkish red color than Burmese rubies. These rubies are known for their vibrant color and affordability.
- Tanzania: Tanzanian rubies are relatively new to the market and are known for their rich red color and excellent clarity. They are often compared to Burmese rubies in terms of quality.
- Vietnam, Thailand, and Sri Lanka: These countries also produce rubies, though they are generally less valuable than those from Myanmar and Madagascar. The rubies from these regions may exhibit a range of colors, from deep red to pinkish red.
Ruby is typically mined using traditional methods, including alluvial and hard rock mining. Alluvial mining involves sifting through riverbeds and sediment to find loose ruby crystals, while hard rock mining requires excavating deep into the Earth's crust to extract ruby-bearing rocks.
Once extracted, rubies are often heat-treated to enhance their color and clarity. This process can improve the gem’s appearance and increase its value, though it is important to disclose any treatments when selling ruby jewelry.
Gemological Properties
Ruby is one of the hardest natural gemstones, ranking 9 on the Mohs scale of hardness. This makes it highly durable and suitable for everyday wear, particularly in rings and other jewelry that may be subjected to frequent contact with surfaces. Its toughness and resistance to scratching make it an excellent choice for engagement rings and other pieces that are worn regularly.
The chemical composition of ruby is aluminum oxide (Al₂O₃), with trace amounts of chromium responsible for its red color. The more chromium present in the gem, the deeper and more intense the red color. The most valuable rubies exhibit a deep, rich red with a slight bluish undertone, a color known as "pigeon blood red."
In terms of clarity, natural rubies often contain inclusions, which are internal features that can affect the gem’s appearance and value. These inclusions are typically microscopic and do not detract from the gem’s beauty or durability. When selecting a ruby, it is important to look for stones that are "eye-clean," meaning that any inclusions are not visible to the naked eye.
The cut of a ruby is also crucial to its overall appearance and value. A well-cut ruby will reflect light beautifully, enhancing its color and brilliance. Common ruby cuts include the brilliant cut, emerald cut, and pear cut, each of which can highlight different aspects of the gem’s beauty.
Ruby is typically found in a range of red hues, from deep red to pinkish red, depending on the concentration of chromium and the presence of other trace elements. The most valuable rubies are those with a deep, uniform red color and minimal inclusions.
When choosing ruby jewelry, it is important to consider the gem’s carat weight, color, clarity, and cut. Larger rubies are rarer and more valuable, especially those with a deep red color and excellent clarity. A ruby with a high color saturation and a well-executed cut will command a higher price than a similar-sized ruby with a lighter color or a poorly cut gem.
Symbolism and Metaphysical Beliefs
Ruby has long been associated with powerful symbolism and metaphysical properties. As the birthstone for July, it is believed to carry the qualities of passion, love, vitality, and protection. In many cultures, ruby has been considered a gem of strength and courage, often worn by warriors and leaders for protection and inspiration.
In ancient times, ruby was believed to have healing properties, particularly for the heart and circulatory system. It was thought to stimulate the heart, improve energy levels, and promote overall vitality. Some cultures also believed that ruby could enhance courage and confidence, making it a popular gem for those in positions of power or leadership.
Ruby is also associated with love and romance. In many traditions, ruby was considered a symbol of true love and was often given as a token of affection. It was believed to strengthen romantic relationships and promote deep emotional connections between partners. This symbolism continues today, with ruby rings being popular choices for engagement and anniversary jewelry.
In addition to its association with love and vitality, ruby is also believed to bring good fortune and success. In many cultures, ruby was considered a lucky gem that could attract wealth and prosperity. It was often worn by businesspeople, politicians, and other individuals seeking success and recognition.
For those born in July, ruby is more than just a gemstone—it is a symbol of identity and inner strength. Wearing a ruby ring or other ruby jewelry is thought to enhance personal power, confidence, and emotional resilience. This makes ruby a meaningful and powerful birthstone for July-born individuals.
Care and Cleaning
Due to its high hardness and durability, ruby is relatively easy to care for and maintain. However, like all gemstones, it requires proper care to preserve its beauty and longevity. Ruby jewelry should be stored in a soft, padded container to prevent scratches and damage from other jewelry pieces. Avoid exposing ruby to harsh chemicals or abrasive materials, as these can dull its surface and affect its appearance.
When cleaning ruby jewelry, it is best to use a soft, lint-free cloth and a mild detergent solution. Avoid using ultrasonic cleaners or steam cleaners, as these can potentially damage the gemstone or the setting. If a ruby is heat-treated, it may be more sensitive to extreme temperatures and should be cleaned with extra care.
For ruby rings, it is important to avoid excessive exposure to impact or pressure, as this can potentially damage the stone or the setting. If a ruby becomes loose or damaged, it should be inspected by a professional jeweler to ensure that it is properly secured and maintained.
Proper care and maintenance will help ensure that ruby jewelry remains beautiful and valuable for generations to come. With its durability and timeless appeal, ruby is an excellent investment in both beauty and meaning.
