History and Lore of the July Birthstone
Ruby has been treasured for millennia, with historical records and archaeological evidence pointing to its use in ancient civilizations across the world. One of the earliest known sources of ruby is Myanmar (formerly Burma), where the Mogok region has been a prominent source of high-quality rubies for centuries. The gem has been found in other regions as well, including Thailand, India, and Sri Lanka, often traded along ancient routes that connected the East and the West.
The sources consulted in this article consistently reference the historical significance of ruby in various cultures. In Medieval Europe, ruby was associated with wisdom, wealth, and success in love. It was believed to bring protection and even to predict misfortune or danger. Some historical accounts suggest that rubies could heal blood-related ailments, a belief that may have stemmed from their red color, which is reminiscent of human blood.
In Burmese culture, ruby was considered a stone of invincibility. Warriors would wear ruby in battle, believing that the gemstone granted them strength and protection. This practice reflects the gem’s broader association with courage and vitality, themes that continue to resonate in modern times.
The sources also note that ruby appears explicitly in the Bible, highlighting its ancient significance and the reverence it was afforded by early societies. Additionally, royal families across the globe have prized ruby as a symbol of power and wealth. From the British Crown Jewels to the royal courts of India, ruby has long adorned crowns, scepters, and other regalia, signifying the authority and prestige of the wearer.
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 sapphire is the presence of chromium, which gives it its characteristic red color. The amount of chromium in the stone affects the intensity of the red hue—higher concentrations result in deeper, more saturated colors.
The finest rubies, often referred to as “pigeon blood” rubies, exhibit a deep red with a subtle hint of purple. This term is most commonly associated with Burmese rubies from the Mogok region. The presence of trace elements such as iron and titanium can also influence the secondary hues found in rubies, including pinkish, purplish, and orangish tones.
Ruby is typically found in metamorphic rocks such as marble and in alluvial deposits. These deposits form through geological processes that involve the transformation of limestone and other minerals under high pressure and temperature. Once formed, rubies are often eroded and transported by water, settling in sedimentary layers where they can be mined.
The sources consulted for this article mention several key ruby-producing regions:
- Myanmar (Burma) – Known for producing some of the finest and most valuable rubies in the world.
- Vietnam – Has emerged as a significant source of high-quality rubies in recent decades.
- Mozambique – Discovered in the late 20th century, this region now produces rubies with a distinctive pinkish hue.
- Afghanistan – Known for producing rubies with a slightly more pinkish tone than those from other regions.
- Sri Lanka – While more commonly known for its sapphires, Sri Lanka also produces rubies with a soft, pinkish-red color.
- Tajikistan and Pakistan – These Central Asian countries have also become important ruby sources in recent years.
The geological diversity of ruby sources means that the gemstone can exhibit a wide range of colors and characteristics, depending on its origin. This variation makes ruby not only valuable but also interesting from a gemological and aesthetic perspective.
Gemological Properties of Ruby
Understanding the gemological properties of ruby is essential for both jewelers and collectors. Ruby is a durable gemstone, with a hardness of 9 on the Mohs scale, making it suitable for everyday wear in rings, bracelets, and other types of jewelry. Its durability is one of the reasons it has been so widely used in jewelry throughout history.
The refractive index of ruby ranges from 1.76 to 1.78, and it exhibits strong pleochroism, meaning it can display different colors when viewed from different angles. The most desirable ruby color is a deep red with a slight purplish overtone, often described as “pigeon blood.”
Ruby is also known for its inclusions, which are natural characteristics that can enhance the stone’s beauty and value. These inclusions are often referred to as “silk” and can give ruby a velvety appearance. While some inclusions may reduce the clarity of the gemstone, they are generally considered a positive feature in ruby because they indicate a natural, untreated stone.
The carat weight of ruby also plays a significant role in its value. Large, high-quality rubies are extremely rare, and their prices can reach astronomical levels. The most valuable rubies are those with a deep red color, excellent clarity, and a good cut that maximizes their brilliance and fire.
Symbolism and Metaphysical Beliefs
Throughout history, ruby has been associated with a wide range of symbolic and metaphysical properties. In many cultures, it has been seen as a stone of passion, vitality, and protection. Ancient civilizations believed that ruby could enhance courage, bring good fortune, and ward off negative energies.

Care and Cleaning of Ruby Jewelry
Ruby is a durable gemstone, but it still requires proper care to maintain its beauty and longevity. Due to its high hardness on the Mohs scale, ruby is resistant to scratches and abrasion. However, it can still be damaged by impact or exposure to harsh chemicals.
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 surface of the gemstone. Ultrasonic cleaners are generally safe for ruby, but it is advisable to avoid using them if the stone has any inclusions or fractures that could be affected by the vibrations.
It is also important to avoid exposing ruby to sudden temperature changes, as this can cause the stone to crack or break. When storing ruby jewelry, it is best to keep it in a soft pouch or separate compartment to prevent it from coming into contact with other hard objects that could cause scratches.
For ruby jewelry that has been professionally set in a ring or other piece, it is recommended to have it inspected by a jeweler periodically to ensure that the setting is secure and that the stone remains in good condition.
