Ruby, the vibrant red gemstone and official birthstone for July, holds a distinguished place in the world of gemology and jewelry. Its deep crimson hue, symbolizing love, vitality, and power, has captivated cultures for millennia. Known as the “king of precious stones” in ancient India and believed to bring invincibility in battle by Burmese and Chinese warriors, ruby is more than just a gem—it is a symbol of strength and enduring beauty.
As a birthstone, ruby is cherished by those born in July, and its historical significance is as rich as its color. This article explores the ruby’s geological origins, its cultural and historical roles, its gemological properties, and the care it requires to preserve its brilliance. Whether you're a gemstone enthusiast, a jewelry buyer, or simply curious about the gemstone of July, this article offers a comprehensive look at the ruby and its enduring legacy.
Rubies are formed deep within the Earth's crust under extreme heat and pressure. They are a variety of the mineral corundum, which also includes sapphires. The red color in rubies is due to trace amounts of the element chromium. The more chromium present, the deeper and richer the red color becomes. The finest rubies exhibit a deep red with a hint of purple, known in the trade as “pigeon’s blood.” This term describes the most valuable and sought-after rubies in the world.
The formation of rubies is a slow and intricate process that can take millions of years. They are typically found in metamorphic rocks, such as marble, and are often discovered in regions with specific geological conditions. The most famous ruby deposits are found in Myanmar (formerly Burma), where the gem has been mined for centuries. Other notable sources include Thailand, Sri Lanka, India, and parts of Africa and South America. These regions provide a diverse range of ruby colors and qualities, each with its own unique characteristics.
The rarity of high-quality rubies contributes to their value and desirability. While corundum is a relatively common mineral, the presence of chromium that gives rubies their distinctive red color is uncommon. This rarity, combined with the gem's hardness and beauty, makes rubies highly prized in the jewelry industry. The geological properties of rubies not only determine their appearance but also influence their durability and suitability for various types of jewelry.
History and Lore
The history of the ruby is as rich and vibrant as its color. This gemstone has been revered for thousands of years, with its allure and symbolism evolving across different cultures and eras. In ancient India, ruby was known as the “king of precious stones” for its rarity, hardness, and beauty. It was believed to possess mystical powers and was often associated with the life force of blood. The gem was a symbol of power and youthful energy in Indian jewelry, and its use in royal regalia and ceremonial ornaments underscored its significance.
In medieval Europe, ruby was associated with health, wisdom, wealth, and success in love. It was believed that rubies could predict misfortune or danger, and some claimed they could cure inflammatory diseases and soothe anger. These beliefs were not unfounded in the context of the time, as many gemstones were thought to have healing and protective properties. The ruby was also a popular choice for signet rings, used to mark documents and seal important agreements.
In ancient China and Burma, ruby was believed to bring invincibility in battle. Warriors would embed rubies into their bodies, believing they would become impervious to harm. This practice highlights the gem’s symbolic power and the deep cultural significance it held in these regions. The ruby was also associated with the sun, a symbol of strength and vitality, further reinforcing its connection to power and energy.
The ruby's journey to becoming the modern birthstone for July is a testament to its enduring appeal. In the early 20th century, the National Association of Jewelers—now known as Jewelers of America—standardized the list of birthstones. While onyx had previously been associated with July, ruby was officially designated as the primary birthstone for the month in 1912. This shift was influenced by the gem's rarity, beauty, and cultural significance, which made it a natural choice for a birthstone. Despite this official designation, onyx has remained an acknowledged alternative for July, reflecting the gem's continued popularity and symbolic value.
The ruby's connection to the zodiac sign Leo, which spans part of July, further cements its symbolic tie to the month. Leo is associated with traits such as strength, confidence, and leadership, qualities that resonate with the ruby's symbolism. This alignment between the gemstone and the zodiac sign adds another layer of cultural significance to the ruby's status as the birthstone for July.
Geological Formation and Sources
Rubies are formed through a complex geological process that involves the transformation of minerals under extreme heat and pressure. They are a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). The red color in rubies is caused by the presence of trace amounts of chromium (Cr), which substitutes for some of the aluminum in the crystal structure. The more chromium present, the deeper and richer the red color becomes. The finest rubies, known as "pigeon's blood" rubies, exhibit a deep red with a hint of purple, a color that is highly prized in the gemstone trade.
The formation of rubies typically occurs in metamorphic rocks, such as marble, which are formed when existing rock is subjected to high temperatures and pressures. This process can take millions of years and is responsible for the unique characteristics of rubies. The conditions required for ruby formation are rare, which contributes to the gem's scarcity and value. The geological properties of rubies not only determine their appearance but also influence their durability and suitability for various types of jewelry.
The most famous ruby deposits are found in Myanmar (formerly Burma), where the gem has been mined for centuries. These rubies are known for their exceptional quality and vivid red color, making them highly sought after in the global market. Other notable sources of rubies include Thailand, Sri Lanka, India, and parts of Africa and South America. Each of these regions produces rubies with unique characteristics, influenced by the specific geological conditions in which they are formed.
The rarity of high-quality rubies is one of the key factors that contribute to their value. While corundum is a relatively common mineral, the presence of chromium that gives rubies their distinctive red color is uncommon. This scarcity, combined with the gem's hardness and beauty, makes rubies highly prized in the jewelry industry. The geological properties of rubies not to only determine their appearance but also influence their durability and suitability for various types of jewelry.
Gemological Properties
Rubies are among the most valuable and sought-after gemstones in the world, and their desirability is largely due to their unique gemological properties. As a variety of corundum, rubies are composed of aluminum oxide (Al₂O₃) with trace amounts of chromium responsible for their red color. The gem's hardness, clarity, and color are key factors that determine its value and quality.
The hardness of a ruby is measured on the Mohs scale, which ranges from 1 (softest) to 10 (hardest). Rubies rank at 9 on this scale, making them second only to diamonds in hardness. This high hardness makes rubies extremely durable and suitable for use in various types of jewelry, including rings, bracelets, and earrings. The gem's toughness, or resistance to breakage, is also high, which means that it can withstand normal wear and tear without chipping or cracking.
The clarity of a ruby refers to the presence of inclusions or internal flaws. While most rubies contain some inclusions, these can often enhance the gem's character and uniqueness. Inclusions in rubies can include small crystals, feathers, or silk-like patterns that are visible under magnification. The presence of these inclusions is generally accepted as natural and can even be used to identify the origin of the ruby. For example, rubies from Myanmar often contain inclusions that resemble needle-like silk, while those from Thailand may have a different appearance.
The color of a ruby is perhaps the most important factor in determining its value. The finest rubies exhibit a deep red with a hint of purple, known in the trade as "pigeon's blood." This term describes the most valuable and sought-after rubies in the world. The intensity of the red color is influenced by the amount of chromium present in the gem. The more chromium, the deeper and richer the red color becomes. However, an excess of chromium can result in a brownish or blackish tint, which reduces the gem's value.
The cut of a ruby is also crucial in showcasing its beauty. Rubies are often cut in a variety of styles, including emerald, oval, cushion, and round cuts. The goal of the cut is to maximize the gem's brilliance and color. A well-cut ruby will reflect light in a way that enhances its red color and creates a sense of depth and dimension. The cut can also influence the gem's durability, as certain cuts may be more prone to chipping or breaking.
The carat weight of a ruby refers to its size and is measured in carats, with one carat equal to 200 milligrams. Larger rubies are generally more valuable, but the price per carat can vary depending on the gem's color, clarity, and cut. Exceptionally large rubies, especially those with a "pigeon's blood" color, can command extremely high prices in the market.
Overall, the gemological properties of rubies—hardness, clarity, color, cut, and carat weight—contribute to their value and desirability. These properties not only determine the gem's appearance but also influence its durability and suitability for various types of jewelry. Whether used in a simple ring or a grand piece of jewelry, rubies are prized for their beauty, rarity, and enduring appeal.

Care and Cleaning
Maintaining the brilliance and longevity of a ruby requires proper care and cleaning practices. Due to its hardness and durability, rubies are relatively easy to maintain compared to other gemstones. However, there are specific steps that should be followed to ensure that the gem remains in optimal condition.
First and foremost, it is important to store rubies in a way that prevents them from coming into contact with other gemstones or hard surfaces. Rubies are rated at 9 on the Mohs scale of hardness, making them one of the hardest gemstones. However, they can still scratch other gemstones or become scratched themselves if not stored properly. A soft, lined jewelry box or a separate compartment is ideal for storing rubies to prevent damage.
Cleaning a ruby is a straightforward process, but it is important to use the right methods. A mild soap solution and a soft cloth are typically sufficient for cleaning a ruby. The gem can be soaked in the solution for a few minutes and then gently scrubbed with a soft-bristled brush to remove any dirt or debris. It is important to avoid using harsh chemicals or abrasive materials, as these can damage the gem's surface or affect its color.
For more thorough cleaning, ultrasonic cleaners can be used, but it is important to ensure that the ruby is free of any inclusions that could be damaged by the vibrations. Inclusions in rubies are common and can include small crystals, feathers, or silk-like patterns. These inclusions are generally accepted as natural and can even be used to identify the origin of the ruby. However, if a ruby has large or fragile inclusions, it is best to avoid using an ultrasonic cleaner to prevent any potential damage.
Steam cleaning is another effective method for cleaning rubies, but it should be used with caution. The high heat and pressure of steam can affect the gem's color or cause any inclusions to expand. It is generally recommended to use steam cleaning only if the ruby is known to be free of inclusions or if the gem has been treated in a way that makes it more resistant to heat.
When it comes to polishing a ruby, it is best to have it professionally done. While a soft cloth can be used to wipe the gem and remove any excess water or dirt, polishing should be left to a jeweler with the appropriate tools and expertise. Over-polishing can wear down the gem's surface and reduce its brilliance, so it is important to avoid using any abrasive materials or techniques.
Regular inspection of the ruby is also important to ensure that it remains in good condition. This includes checking for any loose settings, damaged prongs, or signs of wear. If any issues are detected, it is best to have the jewelry repaired by a professional jeweler. Loose stones can become lost or damaged if not addressed promptly, and damaged prongs can lead to further complications.
By following these care and cleaning practices, the ruby can maintain its brilliance and beauty for many years. Whether used in a simple ring or a grand piece of jewelry, proper care ensures that the ruby remains a cherished and valuable gemstone.
