History and Lore
The ruby has a long and storied history, with roots that stretch back to ancient civilizations. Its vibrant red color has been associated with life, energy, and vitality, making it a symbol of power and regality across cultures. In ancient India, the ruby was revered as the "king of precious stones." This title reflected not only its rarity and hardness—second only to the diamond—but also its perceived mystical properties. Indian jewelers and warriors believed that the ruby could bring strength and invincibility, making it a treasured adornment for both royalty and soldiers.
In medieval Europe, the ruby was similarly esteemed. It was believed to bestow health, wisdom, and success in love. These associations were rooted in the ruby's deep red color, which was linked to the life force of blood. Some historical accounts even suggest that rubies could predict misfortune or danger, or cure inflammatory diseases and soothe anger. These beliefs, though not scientifically validated, highlight the ruby's powerful symbolic role in the medieval imagination.
The ruby also played a significant role in the beliefs of the Burmese people. Warriors would wear rubies in battle, convinced that the gemstone made them invincible. This belief in the ruby’s protective powers underscores its importance in both spiritual and practical contexts.
The ruby's journey to becoming the official birthstone for July is a reflection of its historical significance and enduring appeal. While the origins of birthstone traditions are often tied to biblical texts, such as the Aaronic breastplate or the foundation of New Jerusalem, the ruby's designation as the July birthstone is a more modern assignment. Nonetheless, it retains the rich symbolism and cultural associations that have made it a cherished gemstone across time.
Geological Formation and Sources
The ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). What distinguishes a ruby from other corundum varieties is the presence of trace amounts of chromium, which imparts its characteristic red color. The more chromium present in the gemstone, the deeper and more intense the red hue. The finest rubies are known in the trade as "pigeon’s blood" for their deep red color with a hint of purple.
Geologically, rubies form under intense heat and pressure in metamorphic rocks. These conditions cause the aluminum oxide to crystallize, with trace elements like chromium altering the color of the gemstone. The formation process is complex and requires specific geological conditions, which is why rubies are relatively rare and highly valued in the gemstone market.
The primary sources of rubies include several countries around the world. Myanmar, formerly known as Burma, is particularly renowned for producing the finest rubies, especially those with the coveted "pigeon’s blood" color. Other notable ruby-producing regions include Thailand, Sri Lanka, Tanzania, and Madagascar. Each of these locations contributes to the global supply of rubies, with variations in color, clarity, and quality depending on the geological conditions of the region.
The rarity of high-quality rubies, combined with their stunning color and durability, makes them one of the most sought-after gemstones in the world. The ruby's position as the July birthstone is thus well-earned, as it represents both the beauty and the enduring legacy of this remarkable gemstone.
Gemological Properties
From a gemological perspective, the ruby is a remarkable gemstone that stands out for its hardness, color, and durability. On the Mohs scale of mineral hardness, which ranges from 1 (softest) to 10 (hardest), the ruby ranks a 9. This makes it second only to the diamond in terms of hardness. Such a high level of hardness means that rubies are highly resistant to scratches and abrasions, making them ideal for use in everyday jewelry. This durability is one of the reasons why rubies have been used in rings, pendants, and other wearable pieces throughout history.
The ruby's color is perhaps its most defining characteristic. As previously mentioned, the red color is due to the presence of chromium. The finest rubies display a deep red with a slight purplish hue, a color known in the trade as "pigeon’s blood." This term refers to the vivid, almost blood-like red that is considered the most valuable and desirable in the market. The intensity of the red color is directly related to the amount of chromium in the gemstone. However, too much chromium can lead to a darker, less desirable color, so the ideal balance is crucial for a high-quality ruby.
In terms of clarity, rubies can vary significantly. Some rubies are nearly flawless, while others may contain inclusions—small internal or surface-reaching features that can affect their appearance and value. These inclusions are often natural and can be used to determine the origin of a ruby, as certain types of inclusions are characteristic of specific geographic regions. For example, rubies from Myanmar often contain silk-like inclusions that give the gemstone a velvety appearance, while those from Thailand may have a different type of internal structure.
The cut of a ruby is also an important factor in its overall appearance and value. Rubies are typically cut in a way that maximizes their color and brilliance. Common cuts include the emerald cut, which emphasizes clarity and color, and the round brilliant cut, which enhances the gemstone's sparkle. The choice of cut can significantly influence the ruby's visual appeal and market value.
Other gemological properties of the ruby include its refractive index and specific gravity. The refractive index measures how light bends as it passes through the gemstone, and for rubies, it typically ranges from 1.76 to 1.78. This high refractive index contributes to the ruby's brilliance and fire. The specific gravity of a ruby, which is the ratio of its weight to that of an equal volume of water, is around 4.00. This relatively high specific gravity is due to the density of the aluminum oxide and the presence of chromium.
These gemological properties collectively define the ruby's unique characteristics and make it one of the most valuable and desirable gemstones in the world. Whether admired for its hardness, color, or clarity, the ruby stands as a testament to the beauty and complexity of natural gemstones.
Symbolism and Metaphysical Beliefs
The ruby has long been associated with a range of symbolic and metaphysical meanings, reflecting its deep red color and perceived mystical properties. Across different cultures and historical periods, the ruby has been regarded as a powerful gemstone that can influence emotions, health, and even destiny.

Care and Cleaning
Given its high hardness and durability, the ruby is a relatively resilient gemstone that can withstand everyday wear. However, proper care and cleaning are essential to maintain its beauty and longevity. The ruby's hardness on the Mohs scale (9) makes it resistant to scratches and abrasions, but it is still susceptible to damage from other sources, such as extreme heat, sudden temperature changes, and exposure to harsh chemicals.
One of the most important considerations in caring for a ruby is to avoid exposing it to high temperatures. While the ruby itself is stable under normal conditions, sudden temperature changes can cause it to crack or fracture. This is particularly important for rubies that may contain inclusions or fractures, as these can be more sensitive to thermal shock. Therefore, it is advisable to avoid subjecting a ruby to extreme heat, such as from a torch or a hot oven, and to allow it to acclimate gradually to temperature changes.
Cleaning a ruby requires a gentle approach to avoid damaging its surface or any surrounding jewelry settings. A mild soap and warm water solution is typically sufficient for cleaning a ruby. The gemstone can be soaked in the solution for a few minutes, after which it can be gently scrubbed with a soft-bristled brush to remove any dirt or debris. It is important to avoid using ultrasonic cleaners or steam cleaners, as these can cause damage to the ruby, especially if it contains inclusions or fractures. Ultrasonic cleaners can also loosen the gemstone's setting, potentially causing it to become dislodged.
When storing a ruby, it is best to keep it in a soft cloth or a lined jewelry box to prevent it from coming into contact with other gemstones or hard surfaces that could cause scratches. If multiple gemstones are stored together, it is advisable to separate them to avoid any potential damage. This is particularly important for rubies, as their high hardness means that they can scratch other gemstones that are softer than them.
For those who wear ruby jewelry regularly, it is a good idea to have it professionally cleaned and inspected periodically. A professional jeweler can check for any signs of wear, such as loose settings or damage to the gemstone, and provide recommendations for proper care and maintenance. This can help ensure that the ruby remains in excellent condition and continues to shine brightly for years to come.
In summary, while the ruby is a durable and resilient gemstone, it still requires thoughtful care and cleaning to preserve its beauty and value. By following these guidelines, ruby owners can enjoy their gemstone's vibrant color and enduring charm for generations to come.
