Introduction
The ruby is the July birthstone, revered for its deep red color and associations with passion, vitality, and protection.

As a variety of corundum, the ruby ranks among the hardest and most durable gemstones, making it ideal for jewelry. This article explores the ruby's geological formation, historical significance, gemological characteristics, and its role in both traditional and modern contexts. Additionally, it provides insights into how to care for ruby jewelry, ensuring its longevity and brilliance.
History and Lore
The ruby has a rich and varied history, with mentions dating back to ancient civilizations. In ancient India, the ruby was known as the "king of precious stones," a title that reflects its esteemed status. Indian jewelers and nobles prized the ruby for its beauty and perceived mystical properties, often incorporating it into royal regalia and sacred artifacts. The gemstone was believed to possess the power to enhance vitality and bring good fortune to its wearer.
In medieval Europe, rubies were associated with life and vitality. They were thought to be capable of predicting misfortune or danger, a belief that led many to carry ruby stones for protection. Warriors, particularly in Burma (now Myanmar), wore rubies into battle, believing they would make them invincible. These cultural associations highlight the ruby's enduring symbolic power across different societies.
The ruby's presence in religious texts, such as the Bible, further underscores its historical significance. It is mentioned four times in the Bible, often in contexts that emphasize its rarity and value. These references contributed to the ruby's perception as a sacred and powerful gemstone.
In the 20th century, the ruby was officially designated as the modern July birthstone by the Jewelers of America in the 1950s. This designation solidified its place in the modern birthstone tradition, making it a popular choice for jewelry and gifts. Additionally, the ruby is traditionally associated with the 15th and 40th wedding anniversaries, symbolizing enduring love and passion.
Geological Formation and Sources
The ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). What distinguishes rubies from sapphires, another corundum variety, is the presence of trace amounts of chromium, which imparts the characteristic red color. The more chromium present, the deeper and more intense the red hue. The finest rubies exhibit a deep red with a hint of purple, a color known in the trade as "pigeon's blood."
Rubies form under high-pressure and high-temperature conditions, typically in metamorphic rocks. The most famous ruby deposits are found in Myanmar (formerly Burma), where the gemstone has been mined for centuries. Other notable sources include Thailand, Sri Lanka, Tanzania, and Afghanistan. Each of these regions produces rubies with unique characteristics, influenced by the geological conditions of their respective locations.
The process of ruby formation is a slow and intricate one. Over millions of years, aluminum and oxygen combine to form corundum. The introduction of chromium during this process leads to the development of ruby. The presence of other trace elements can also influence the color and clarity of the gemstone. For example, rubies with a pinkish hue are often referred to as "pink sapphires," a term used when the chromium content is lower than that of traditional rubies.
Mining rubies is a complex and often labor-intensive process. In Myanmar, rubies are typically extracted from alluvial deposits, where they have been transported by water over long distances. These deposits are found in areas with a history of ruby production, making them highly sought after by miners and gemologists alike. The quality of rubies from these regions is renowned, with Burmese rubies often considered the most valuable in the world.
Gemological Properties
The ruby is one of the hardest and most durable gemstones, with a hardness of 9 on the Mohs scale. This high hardness makes it suitable for everyday wear, particularly in rings and other jewelry that may be subject to frequent use. Its durability is due to the strong atomic structure of corundum, which resists scratching and abrasion.
The refractive index of ruby typically ranges from 1.76 to 1.78, allowing it to display a brilliant and lively appearance when cut and polished. The gemstone's color is one of its most defining features, with the most valuable rubies exhibiting a deep red to purplish red hue. The term "pigeon's blood" is often used to describe the finest ruby color, a vivid red with a slight blue or purple undertone that enhances its brilliance.
Clarity in rubies can vary, with some stones exhibiting a high degree of transparency and others containing inclusions. Inclusions are natural imperfections that form during the gemstone's creation and can be used to determine its origin and authenticity. While inclusions can affect the value of a ruby, they are also considered by some to add character and individuality to the gemstone.
The cut of a ruby plays a crucial role in its appearance and value. The most common cuts for rubies include the emerald cut, round brilliant cut, and pear cut. Each cut is designed to maximize the gemstone's brilliance and color. The emerald cut, for example, is known for its ability to enhance the ruby's color and clarity, while the round brilliant cut is favored for its ability to reflect light and create a sparkling effect.
Carat weight is another important factor in determining the value of a ruby. Larger rubies are generally more valuable, especially if they exhibit a high degree of color and clarity. However, the price per carat can vary significantly depending on the gemstone's quality and origin. For example, a 1-carat Burmese ruby in the pigeon's blood color can command a much higher price than a similar-sized ruby from another region.
Symbolism and Metaphysical Beliefs
The ruby has long been associated with symbolism and metaphysical beliefs, reflecting its cultural and historical significance. In many cultures, the ruby is seen as a symbol of love, passion, and vitality. Its deep red color is often linked to the life force and the heart, making it a powerful gemstone for those seeking emotional and physical energy.
In ancient times, rubies were believed to possess protective and healing properties. Warriors in Burma and other regions wore rubies into battle, believing they would grant them invincibility and strength. These beliefs persisted through the ages, with many cultures attributing the ruby with the ability to ward off danger and bring good fortune to its wearer.
The ruby's association with love and romance has made it a popular choice for engagement rings and other romantic jewelry. Its vibrant red color is often seen as a symbol of deep affection and devotion, making it a meaningful gift for significant occasions. In some traditions, the ruby is also believed to enhance one's confidence and courage, making it a valuable gemstone for those seeking to boost their self-esteem.
Metaphysical properties attributed to the ruby include the ability to stimulate the heart chakra and promote a sense of well-being. It is believed to enhance vitality and energy, making it a popular choice for those seeking to increase their physical and emotional strength. Some practitioners of crystal healing use rubies to address issues related to the heart and circulatory system, believing that the gemstone can help improve blood flow and overall health.
Care and Cleaning
Proper care and cleaning are essential to maintaining the beauty and durability of ruby jewelry. Given its high hardness and durability, the ruby is well-suited for everyday wear. However, it is still important to handle ruby jewelry with care to prevent damage and ensure its longevity.
One of the most effective ways to clean ruby jewelry is to use a soft, lint-free cloth and warm, soapy water. Gently wipe the gemstone and surrounding metal to remove dirt and oils. It is important to avoid using harsh chemicals or abrasive materials, as these can scratch the surface of the gemstone or damage the metal setting.
Ultrasonic cleaners can be used to clean ruby jewelry, but it is advisable to consult with a professional jeweler before doing so. Some inclusions within the ruby may be sensitive to ultrasonic vibrations, and prolonged exposure can potentially cause damage. Steam cleaning is generally not recommended for rubies, as the high heat and moisture can affect the gemstone's clarity and color.
When storing ruby jewelry, it is best to keep it in a soft, protective pouch or a jewelry box with individual compartments to prevent scratches. Avoid storing rubies with other gemstones or metals that may scratch the surface of the ruby. Additionally, it is important to remove ruby jewelry before engaging in activities that may expose it to impact or abrasion, such as sports or heavy lifting.
Regular inspections by a professional jeweler can help identify any potential issues with the setting or the gemstone itself. Loose settings or damaged prongs can be repaired to ensure the ruby remains securely in place. By following these care and cleaning guidelines, ruby jewelry can retain its brilliance and beauty for generations.
