July, the vibrant heart of summer, is synonymous with warmth, energy, and color. Among the many symbols that define this month—scorching heat, backyard barbecues, and the deep red of watermelon and ripe tomatoes—one stands out for its enduring beauty and symbolic power: the ruby. As the birthstone for July, the ruby is not just a gem of exceptional rarity and brilliance but also a stone steeped in centuries of cultural significance and historical reverence.
The ruby, with its unmistakable red hue, is the most coveted of gemstones. It is one of the four traditional precious stones, joining the ranks of diamond, emerald, and sapphire. Unlike these others, however, the ruby’s value is defined not by its lack of color, but by the depth and intensity of its red. Known in the trade as "pigeon's blood," the finest rubies display a deep, vivid red with a subtle hint of purple. This color is the result of the presence of chromium, a trace element that imparts the ruby's iconic hue. The more chromium present in the gemstone, the stronger and more vibrant the red.
The ruby’s connection to the month of July is deeply rooted in history and tradition. While the origins of birthstones are often debated, many historians trace their roots to the ancient Israelite tradition of the High Priest’s breastplate, which was adorned with twelve gemstones, each representing one of the twelve tribes of Israel. Over time, these stones became associated with the twelve months of the year, forming the basis of the modern birthstone tradition. The ruby, with its fiery red color and powerful symbolism, became the designated gemstone for July.
Beyond its historical significance, the ruby holds a special place in gemology due to its unique properties. It is a variety of the mineral corundum, the same mineral that forms sapphires when the trace element is aluminum rather than chromium. Rubies are known for their hardness, ranking 9 on the Mohs scale, second only to diamond. This durability, combined with their brilliant color and refractive qualities, makes them ideal for use in fine jewelry.
In this article, we will explore the ruby in depth. We will examine its geological formation and the locations where it is found, discuss its gemological properties, and uncover the rich symbolism and lore that surround it. We will also consider alternative July birthstones and touch on the care and maintenance of ruby jewelry. Whether you are a gemstone enthusiast, a jewelry buyer, or simply curious about the birthstone of July, this article will provide a comprehensive look at one of the most cherished and powerful gemstones in the world.
History and Lore of the Ruby
The ruby has long been regarded as a gemstone of immense value and significance, both culturally and spiritually. Its association with power, vitality, and passion dates back to ancient civilizations, where it was often considered a stone of the gods. In ancient India, the ruby was known as "ratnaraj," which translates to "king of precious stones." This title was not given lightly—rubies were revered for their rarity, hardness, and the deep red color that symbolized life and energy. Indian royalty and priests often wore ruby jewelry, believing the stone to bring protection, wisdom, and prosperity. The gem was also thought to have the ability to predict danger or misfortune, making it a popular talisman for warriors and leaders alike.
In medieval Europe, the ruby's symbolism took on new dimensions. It was believed to bestow health, wisdom, and success in love. During the Middle Ages, rubies were often included in royal regalia and used in elaborate jewelry to signify nobility and power. Some medieval texts even suggest that the ruby had the power to cure inflammatory diseases and soothe anger, reinforcing its role as a stone of balance and vitality. The belief in the ruby's healing properties extended into the 18th and 19th centuries, with some physicians and alchemists using it in their practices.
Perhaps one of the most fascinating historical associations with the ruby comes from the Burmese warriors of the past. According to historical accounts, Burmese soldiers would wear rubies into battle, believing that the gemstone made them invincible. The ruby was thought to absorb the warrior’s blood and protect him from harm. This belief, while not supported by gemological science, speaks to the deep cultural and spiritual significance that the ruby held in ancient societies.
The ruby's connection to the month of July is also steeped in symbolism. The deep red of the ruby mirrors the intense heat and vibrancy of summer, making it a fitting emblem for the month. Its color is associated with passion, love, and strength, reflecting the energy of the summer season. In many cultures, red is a color of power and vitality, and the ruby's red hue reinforces this connection. As a birthstone for July, the ruby is not just a decorative gem—it is a symbol of the month's essence.
Over time, the ruby has also become a symbol of enduring love and commitment. It is traditionally given as a gift for the 15th and 40th wedding anniversaries, representing the strength and passion of a long-lasting relationship. This tradition further cements the ruby's place in cultural and romantic lore, making it a gemstone that is both historically significant and emotionally meaningful.
Geological Formation and Sources of Ruby
Rubies, like other gemstones, are formed through complex geological processes that take place deep within the Earth's crust. These processes occur over millions of years, resulting in the creation of one of the most sought-after and valuable gemstones in the world. Rubies are a variety of the mineral corundum, which is composed primarily of aluminum oxide (Al₂O₃). What distinguishes a ruby from a sapphire is the presence of the trace element chromium, which imparts the characteristic red color. The more chromium present in the corundum, the stronger and more vibrant the red hue becomes.
The formation of rubies typically occurs in metamorphic rock environments, where existing minerals are subjected to intense heat and pressure. These conditions cause the minerals to recrystallize and form new structures. In the case of rubies, the transformation of corundum into ruby occurs when chromium is introduced into the crystal lattice during the metamorphic process. This process is often associated with the presence of marble, a metamorphic rock that forms from the transformation of limestone under high heat and pressure. The presence of chromium in the surrounding rock is crucial, as it determines the color and quality of the resulting ruby.
Rubies are found in various parts of the world, but some locations are particularly renowned for producing high-quality stones. Myanmar, formerly known as Burma, is one of the most famous sources of rubies. Burmese rubies, especially those from the Mogok region, are highly prized for their deep red color and exceptional clarity. These stones are often described as "pigeon's blood" rubies, a term used to denote the finest quality of rubies with a deep red hue and a slight purplish overtone. Other notable sources of rubies include Thailand, Cambodia, Vietnam, and parts of Africa such as Mozambique and Madagascar. Each of these regions produces rubies with distinct characteristics, influenced by the specific geological conditions and mineral composition of the area.
In addition to natural occurrences, rubies can also be synthesized in laboratory settings. These synthetic rubies, created through processes such as flame fusion or the Czochralski method, have the same chemical composition and physical properties as their natural counterparts. However, they are generally less valuable than natural rubies due to their controlled and predictable formation. The ability to create synthetic rubies has expanded the availability of the gemstone, making it more accessible to a wider audience while preserving the allure and prestige of naturally occurring rubies.
The rarity of high-quality rubies is one of the factors that contribute to their value. Natural rubies with the ideal "pigeon's blood" color and minimal inclusions are extremely rare, making them highly sought after by collectors and jewelers alike. The presence of inclusions, known as "needle-like rutile," can indicate whether a ruby has been treated to enhance its color or clarity. Untreated rubies are particularly valuable, as they retain their natural characteristics without the need for artificial enhancement.
Gemological Properties of the Ruby
Ruby, as a gemstone, possesses a unique set of properties that make it one of the most desirable and valuable gems in the world. These properties are not only important from a scientific and gemological perspective but also play a significant role in determining the stone’s value, durability, and suitability for use in jewelry. Understanding these properties is essential for anyone interested in ruby as a gemstone, whether for investment, collection, or personal adornment.
One of the most defining characteristics of ruby is its color. As mentioned earlier, the gemstone's red color is due to the presence of chromium within its corundum structure. The intensity and tone of the red can vary depending on the concentration of chromium and other trace elements. The most prized rubies exhibit a deep, rich red known as "pigeon's blood," a term used to describe a color that is both vivid and slightly purplish. This color is highly sought after and is often associated with the finest rubies from Myanmar. The color of a ruby is one of the primary factors that determine its value, with the most intensely colored stones commanding the highest prices.
In addition to color, the clarity of a ruby is another important factor. Like all gemstones, rubies can contain inclusions, which are natural imperfections or internal characteristics that formed during the stone’s creation. These inclusions can range from small, barely visible specks to larger features that affect the gemstone's transparency. While some inclusions are considered natural and can even be used to determine the origin of a ruby, others can detract from the stone’s beauty and value. The presence of needle-like inclusions, known as "silk," is common in rubies and can give the gemstone a velvety appearance. However, excessive inclusions or those that are particularly noticeable can reduce the stone’s clarity and, consequently, its value.
The hardness of a ruby is another key property that contributes to its durability and practicality in jewelry. On the Mohs scale of mineral hardness, ruby ranks a 9, making it one of the hardest gemstones after diamond, which ranks a 10. This high level of hardness means that rubies are resistant to scratches and abrasions, making them suitable for use in a variety of jewelry settings, including rings, bracelets, and earrings. However, despite its hardness, ruby is not completely immune to damage. The gemstone can be brittle and may chip or crack if struck with sufficient force. Therefore, it is important to handle ruby jewelry with care and to avoid subjecting it to extreme impacts.
The cut of a ruby is also a crucial factor in determining its overall appearance and value. The way a ruby is cut can affect how light interacts with the stone, influencing its brilliance and color. A well-cut ruby will allow light to enter the stone, reflect off its internal surfaces, and exit through the top, creating a beautiful and vibrant display of color. The most common cuts for rubies include the brilliant cut, which is designed to maximize the stone’s sparkle, and the step cut, which is used to highlight the gemstone's color and clarity. The choice of cut often depends on the shape and size of the rough stone, as well as the preferences of the jeweler and the client.
The carat weight of a ruby is another factor that affects its value and desirability. Larger rubies are generally more valuable than smaller ones, especially when they exhibit high color quality and clarity. However, the size of a ruby is not the only determining factor; the overall quality of the stone, including its color, clarity, and cut, must be taken into account. A smaller ruby with excellent color and clarity can be more valuable than a larger ruby with a dull or pale red hue.
Symbolism and Metaphysical Beliefs Associated with the Ruby
The ruby has long been associated with a range of symbolic and metaphysical beliefs across different cultures and historical periods. These beliefs often reflect the gemstone's vibrant red color and its perceived connection to life force, vitality, and passion. In many ancient traditions, rubies were considered to possess powerful energies that could influence both the physical and spiritual well-being of the wearer. These beliefs have persisted through the centuries, with the ruby being regarded as a stone of protection, courage, and emotional strength.
In ancient India, the ruby was not only a symbol of power and royalty but also believed to have the ability to enhance one's vitality and energy. Indian texts from as early as the 6th century AD mention the ruby's association with the sun, which was considered the source of life and energy. The gemstone was often worn by warriors and leaders to instill confidence, strength, and invincibility. According to some Indian traditions, rubies were also used in rituals to ward off negative energies and to bring prosperity and success. The belief in the ruby's protective qualities was so strong that it was often carried as a talisman during battles and important ceremonies.
In medieval Europe, the ruby continued to be revered for its symbolic power. It was believed that rubies could bestow wisdom, health, and success in love.

Care and Maintenance of Ruby Jewelry
Given the ruby's status as one of the hardest gemstones, it is relatively durable and well-suited for everyday wear. However, despite its high ranking on the Mohs scale, rubies can still be damaged if not properly cared for. Proper maintenance is essential to preserving the beauty and longevity of ruby jewelry, ensuring that it remains a cherished possession for generations.
One of the key factors in caring for ruby jewelry is understanding the gemstone's hardness and toughness. While rubies are hard and resistant to scratches, they can be brittle and susceptible to chipping or cracking if subjected to sudden impact or pressure. This is particularly important for ruby jewelry, as the gemstone is often set in rings, bracelets, and other pieces that may be exposed to daily wear and tear. To avoid damage, it is advisable to handle ruby jewelry with care and to avoid exposing it to extreme temperatures or sudden temperature changes, which can cause the gemstone to crack.
Cleaning ruby jewelry should be done with gentle methods to avoid damaging the gemstone or its setting. A mild solution of warm water and a few drops of dish soap is an effective and safe way to clean ruby jewelry. The jewelry can be soaked in this solution for a few minutes before being gently scrubbed with a soft-bristled brush to remove dirt and debris. After cleaning, the jewelry should be rinsed thoroughly with warm water and dried with a soft, lint-free cloth. It is important to avoid using harsh chemicals, abrasive cleaners, or ultrasonic cleaners, as these can potentially damage the ruby or its setting. Ultrasonic cleaners, in particular, can cause stress to the gemstone and may lead to fractures, especially if the ruby has inclusions or has been treated.
Storing ruby jewelry properly is another important aspect of its care. To prevent scratches and damage, ruby jewelry should be stored separately from other gemstones, particularly those that are softer or more abrasive. Soft gemstones like pearls, opals, and emeralds can be scratched by the ruby's hardness, while harder gemstones like diamonds can potentially scratch or damage the ruby's surface. A jewelry box with individual compartments or a soft-lined jewelry pouch is an ideal storage solution. It is also advisable to keep ruby jewelry away from direct sunlight for extended periods, as prolonged exposure can cause the gemstone to fade or lose its luster.
For ruby jewelry that has been treated to enhance its color or clarity, special care should be taken to avoid treatments that could reverse or damage the enhancements. Heat treatments, which are commonly used to improve the color of rubies, can sometimes make the gemstone more fragile. In such cases, it is important to follow the care instructions provided by the jeweler or gemologist who owns the piece. If the ruby has been filled with glass or other substances to improve its clarity, it is especially important to avoid exposure to harsh chemicals or extreme temperatures, as these can cause the filling to dissolve or the gemstone to crack.
Regular inspection of ruby jewelry is also recommended to ensure that the gemstone remains secure in its setting. Over time, the prongs or settings that hold the ruby in place can become loose due to normal wear and tear. If a ruby becomes loose or dislodged, it should be taken to a professional jeweler for repair. A loose ruby can easily fall out and be lost, and attempting to secure it without the proper tools and expertise can result in further damage.
By following these care and maintenance practices, ruby jewelry can be preserved for a lifetime, maintaining its beauty and value. Proper care not only enhances the longevity of the gemstone but also ensures that it remains a treasured heirloom, passed down through generations.
