For those born on July 31st, the ruby holds a special place as their birthstone. Known as the “king of gemstones,” the ruby is celebrated for its intense red hue and remarkable durability. As the birthstone for this date, it carries deep symbolic meaning and historical significance, making it a treasured gemstone for centuries. This article explores the geological properties, cultural lore, symbolism, and care requirements of the ruby, offering a comprehensive understanding of this extraordinary stone.
Historical Significance and Lore
The ruby has a rich and storied history that spans across cultures and civilizations. In ancient India, the ruby was known as “ratnaraj,” which means “king of precious stones.” This name was not chosen lightly, as the ruby was believed to possess mystical powers that could confer invincibility to those who carried it. Noblemen would often incorporate rubies into their armor, convinced that these gems would protect them in battle. The belief in the ruby’s protective powers was not limited to India. In ancient Burma (now Myanmar), warriors would insert rubies into their flesh, believing they would become invincible in combat.
The ruby’s association with power and protection extended beyond the battlefield. In medieval Europe, rubies were often worn as talismans to ward off danger and bring good fortune. They were also believed to have the ability to predict misfortune or danger, making them highly sought after by rulers and aristocrats. This belief in the ruby's prophetic powers highlights its importance in both personal and political spheres during these times.
Throughout history, the ruby has been revered for its beauty and symbolic meaning. Its deep red color has been associated with life, vitality, and passion, making it a popular gemstone for jewelry that symbolizes love and commitment. The ruby’s enduring appeal is a testament to its ability to capture the imagination and inspire awe in those who encounter it.
Geological Formation and Sources
The ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). What distinguishes the ruby from other corundum varieties, such as sapphires, is the presence of trace amounts of chromium, which gives the gemstone its characteristic red color. The more chromium present in the corundum, the stronger and deeper the red hue. The finest rubies exhibit a deep red color with a hint of purple, known in the trade as “pigeon’s blood.”
Rubies are formed under extreme heat and pressure deep within the Earth’s crust. Over millions of years, the combination of these geological conditions and the presence of chromium results in the creation of this precious gemstone. The most renowned sources of high-quality rubies are in Myanmar (formerly Burma), where the gemstone has been mined for centuries. Other notable sources include Thailand, Sri Lanka, Madagascar, and parts of Africa and Southeast Asia.
The process of forming a ruby is a slow and intricate one. The mineral corundum is already one of the hardest substances on Earth, ranking at 9 on the Mohs scale of mineral hardness (with a diamond being 10). This hardness, combined with the ruby’s deep red color, makes it a highly desirable gemstone for jewelry and other applications.
Gemological Properties
The ruby’s gemological properties contribute to its status as a highly valued gemstone. Its hardness of 9 on the Mohs scale means that it is extremely durable and resistant to scratches, making it suitable for everyday wear in jewelry. However, despite its hardness, rubies can still be damaged if struck with sufficient force, especially along cleavage planes or if they contain inclusions that weaken the stone.
One of the most distinctive features of the ruby is its color. The deep red hue is caused by the presence of chromium, which gives the gemstone its vibrant and intense appearance. The finest rubies exhibit a color known as “pigeon’s blood,” a term used to describe a deep red color with a slight purple undertone. This color is highly prized in the gemstone trade and can significantly impact the value of a ruby.
In addition to its color and hardness, the ruby also exhibits a refractive index of approximately 1.76–1.78, which contributes to its brilliance and fire when properly cut. The gemstone is typically cut into shapes such as emerald, round brilliant, and cushion cuts, each of which enhances the ruby’s natural beauty in a different way.
Another notable feature of rubies is the presence of inclusions, which are small imperfections within the stone. While these inclusions can affect the clarity and value of a ruby, they are often considered to be a natural part of the gemstone’s character. In some cases, inclusions can create interesting visual effects, such as asterism, which is a star-like pattern caused by the alignment of needle-like inclusions within the stone. These star rubies are particularly sought after and can command high prices in the market.
Symbolism and Metaphysical Beliefs
The ruby has long been associated with powerful symbolism and metaphysical beliefs. Its deep red color has been linked to the heart and blood, symbolizing life, vitality, and passion. In many cultures, the ruby is seen as a symbol of love and commitment, making it a popular gemstone for engagement rings and other romantic jewelry. The ruby’s association with the heart also makes it a powerful stone for promoting emotional strength and resilience.
In addition to its symbolism of love and passion, the ruby is also believed to confer power and protection. In ancient times, it was thought that carrying a ruby could provide invincibility in battle, as seen in the practices of Indian and Burmese warriors. This belief in the ruby’s protective properties has persisted over time, with many people believing that the gemstone can ward off danger and bring good fortune.
The ruby is also associated with courage and confidence. Its vibrant red color is often seen as a symbol of boldness and determination, making it a powerful stone for those who wish to enhance their self-esteem and assertiveness. In metaphysical practices, the ruby is often used to stimulate the heart chakra and promote emotional healing, helping individuals to connect with their emotions and express them more freely.
Care and Maintenance
Given its hardness and durability, the ruby is a relatively easy gemstone to care for. However, to maintain its brilliance and longevity, it is important to follow some basic care and cleaning guidelines. Because rubies are hard and resistant to scratches, they can be cleaned using a soft cloth and warm, soapy water. A mild detergent can be used to remove dirt and grime, and the gemstone can then be rinsed with warm water and dried with a soft cloth.
It is important to avoid exposing rubies to harsh chemicals, as these can damage the stone or its setting. Acidic substances, such as lemon juice or vinegar, should be avoided, as they can erode the surface of the gemstone. Similarly, strong detergents and abrasive cleaners should not be used, as they can scratch the surface of the ruby or its setting.
In addition to chemical exposure, rubies should also be protected from extreme temperatures. Rapid temperature changes can cause the gemstone to crack or chip, so it is best to avoid exposing rubies to extreme heat or cold. This is especially important for rubies that contain inclusions or have been treated to enhance their color.
For more thorough cleaning, a professional jeweler can provide ultrasonic cleaning, which uses high-frequency sound waves to remove dirt and debris from the gemstone and its setting. This method is generally safe for rubies, but it is always a good idea to consult with a jeweler before using this or any other cleaning method.
Ruby in Jewelry
The ruby’s beauty and durability make it an excellent choice for a wide range of jewelry designs. Its deep red color is particularly striking in rings, pendants, and earrings, where it can serve as a focal point or be paired with other gemstones for a more intricate design. The ruby’s hardness makes it suitable for everyday wear, and its vibrant color ensures that it will stand out in any setting.
When choosing ruby jewelry, it is important to consider the cut and clarity of the gemstone, as these factors can significantly impact its appearance and value. A well-cut ruby will exhibit excellent brilliance and fire, while a poorly cut ruby may appear dull or lifeless. Clarity is also an important consideration, as inclusions can affect the gemstone’s transparency and overall beauty.
In addition to traditional ruby jewelry, the gemstone can also be used in more modern and unconventional designs. For example, rubies can be incorporated into minimalist jewelry designs, where their deep red color serves as a bold and eye-catching accent. They can also be paired with other gemstones, such as diamonds or sapphires, to create unique and sophisticated pieces.
