History and Lore of the July Birthstone
Ruby has a long and storied history, with its significance stretching back to ancient civilizations. The gemstone has been treasured across cultures for its beauty, rarity, and symbolic power. In ancient India, ruby was known as ratnaraj, meaning "king of precious stones." This title reflected its perceived value and the belief in its mystical properties. Indian royalty and warriors often adorned themselves with rubies, believing the stones brought protection and invincibility in battle.
The earliest known sources of ruby were in the Mogok region of modern-day Myanmar, where high-quality rubies have been mined for thousands of years. These stones were highly prized and often used in royal regalia and sacred jewelry. In medieval Europe, ruby was regarded as a symbol of the heart and was frequently incorporated into religious and royal ornaments. The gemstone was believed to bring good fortune, passionate love, and a connection to the divine.
The recognition of ruby as the July birthstone is a more recent development. In 1912, the American National Association of Jewelers (now known as Jewelers of America) formalized a standardized list of birthstones, including ruby for July. This decision helped to cement ruby’s place in the modern birthstone tradition and reinforced its association with those born in the seventh month.
Across various cultures, ruby has held deep symbolic meaning. In ancient China, it was believed to promote longevity and vitality. In the Middle East, ruby was associated with protection from evil and was often worn as a talisman. In European folklore, ruby was thought to have the power to predict danger and to cure ailments related to the heart and blood. These diverse beliefs highlight ruby’s universal appeal and enduring mystique.
Geological Formation and Sources of Ruby
Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). What distinguishes ruby from other corundum varieties, such as sapphire, is the presence of chromium, which imparts its characteristic red color. The more chromium present in the crystal structure, the deeper the red hue. Other trace elements can influence the tone of ruby, producing subtle variations in color, including shades of pink, orange, and purple.
The formation of ruby occurs under specific geological conditions. Corundum typically forms in metamorphic rocks, such as marble, or in igneous rocks that have undergone high-pressure and high-temperature environments. The presence of chromium in the Earth’s crust is relatively rare, which contributes to the scarcity and value of ruby. The finest quality rubies are often found in alluvial deposits—where the gemstones have been eroded from their original rock formations and transported by water, resulting in well-shaped, gem-quality stones.
Myanmar (formerly Burma) is the most famous source of ruby, particularly the "pigeon’s blood" rubies from the Mogok region. These stones are renowned for their deep red color with a slight purplish hue and are considered the pinnacle of ruby quality. Other notable ruby-producing countries include Thailand, Sri Lanka, Afghanistan, and Vietnam. Each location produces rubies with distinct characteristics, influenced by the geological conditions and trace elements present in the local environment.
The mining of ruby is often labor-intensive and requires careful extraction to preserve the gemstone’s integrity. In many regions, ruby is mined using traditional methods that have been passed down through generations. The rarity of high-quality ruby, combined with the challenges of mining and cutting, contributes to its high market value.
Gemological Properties of Ruby
Ruby is a gemstone of exceptional hardness and brilliance, making it a favorite in fine jewelry. Its physical and optical properties contribute to its durability and visual appeal. Here are some key gemological characteristics of ruby:
Color: Ruby is known for its intense red color, which ranges from deep crimson to vibrant pinkish red. The most prized color is referred to as "pigeon’s blood"—a vivid red with a slight purplish overtone. This color is highly valued in the trade and commands premium prices.
Hardness: Ruby ranks 9 on the Mohs scale of mineral hardness, second only to diamond. This high hardness makes ruby resistant to scratches and suitable for everyday wear in jewelry.
Refractive Index: Ruby has a refractive index of approximately 1.76–1.78. This high refractive index contributes to the gemstone’s brilliance and fire when cut and polished.
Chemical Composition: Ruby is composed of aluminum oxide (Al₂O₃) with trace amounts of chromium, which gives it its red color. Other trace elements can affect the tone and clarity of the stone.
Clarity: High-quality ruby is typically eye-clean, meaning it has few visible inclusions. However, most rubies contain some inclusions, which are natural features that can enhance the stone’s character and authenticity.
Cut: Rubies are often cut into oval, cushion, or round shapes to maximize their brilliance and color. The choice of cut depends on the stone’s shape and inclusions, as well as the desired aesthetic.
Carat Weight: Ruby is available in a range of sizes, from small gemstones used in earrings and rings to larger stones used in pendants and brooches. Larger, high-quality rubies are extremely rare and valuable.
These properties make ruby a highly desirable gemstone for both collectors and jewelry wearers. Its combination of hardness, color, and brilliance ensures that ruby jewelry remains beautiful and durable over time.
Symbolism and Metaphysical Beliefs of Ruby
Ruby has long been associated with powerful symbolism and metaphysical beliefs. Across cultures and centuries, ruby has been regarded as a stone of passion, vitality, and protection. Its deep red color is often linked to the heart, blood, and life force, making it a symbol of love, courage, and energy.
In ancient times, ruby was believed to possess healing and protective properties. Warriors in Burma and China were known to wear rubies in battle, believing that the gemstone would make them invincible. Some historical accounts suggest that rubies were even inserted into the body, such as being sewn into armor or clothing, to provide protection and strength. In medieval Europe, ruby was thought to have the power to predict danger and to cure inflammatory diseases. It was also believed to promote a calm and clear mind, helping to alleviate anger and emotional distress.
In modern times, ruby is often associated with love and commitment. It is a popular choice for engagement rings and anniversary gifts, symbolizing enduring passion and devotion. Ruby is also believed to bring good fortune and prosperity, making it a valuable talisman for those seeking success and abundance.
The metaphysical properties of ruby are further enhanced by its vibrant color and energy.

These symbolic and metaphysical associations have contributed to ruby’s enduring popularity as a gemstone. Whether worn for its beauty, its meaning, or its history, ruby continues to capture the imagination and admiration of people around the world.
Care and Cleaning of Ruby Jewelry
Proper care and cleaning are essential to maintaining the beauty and longevity of ruby jewelry. Due to its high hardness, ruby is relatively durable and can withstand daily wear. However, it is important to follow specific care guidelines to ensure that the gemstone remains in excellent condition.
Ruby is not sensitive to light, heat, or common household chemicals, which makes it suitable for everyday wear. However, it is advisable to avoid exposing ruby to harsh abrasives or extreme temperatures. While ruby is resistant to scratches, it can still be damaged if exposed to other hard materials, such as diamonds.
When cleaning ruby jewelry, it is best to use mild soap and warm water. A soft brush, such as a toothbrush, can be used to gently scrub the gemstone and remove any dirt or debris. Ultrasonic cleaners can also be used to clean ruby, but it is important to check with a professional jeweler to ensure that the stone is suitable for this method, as some inclusions or treatments may be affected.
It is also recommended to store ruby jewelry separately from other gemstones to prevent scratches. Soft pouches or individual compartments in a jewelry box can help protect the gemstone from contact with other stones or metals.
Regular inspections by a professional jeweler can help identify any potential issues, such as loose settings or damage to the gemstone. If ruby jewelry is damaged, it is best to have it repaired by an experienced jeweler to ensure that the gemstone and setting are properly restored.
By following these care and cleaning practices, ruby jewelry can be enjoyed for generations, preserving its beauty and value over time.
