History and Lore
Ancient Origins and Cultural Significance
Ruby has been cherished for millennia, with references dating back to ancient civilizations. The name "ruby" is derived from the Latin word ruber, meaning red. In ancient times, ruby was believed to be the "king of precious stones," a symbol of power, nobility, and vitality. It was revered by various cultures for its perceived ability to bring good fortune, protect against harm, and enhance love and passion.
In India, ruby was considered a sacred stone associated with the sun god Surya. It was believed to bring energy, vitality, and success. Ancient Hindu texts, such as the Vedas, mention ruby as one of the seven sacred gems. In Burma (now Myanmar), ruby was considered the national gemstone and was believed to bring prosperity and protection to the country. The famous "Pigeon's Blood" ruby from Burma is particularly prized for its vivid red color and exceptional clarity.
In Europe, ruby was a symbol of nobility and was often used in royal regalia. Kings and queens adorned themselves with ruby jewelry to signify their power and divine right to rule. During the Middle Ages, ruby was believed to have protective properties and was used in amulets and talismans to ward off evil spirits and diseases.
Modern Recognition as a Birthstone
The designation of ruby as the birthstone for July has historical roots. In the early 20th century, the National Association of Jewelers in the United States standardized a list of birthstones, assigning ruby to July. This list was later revised in 1912 and again in 2019 by the Gemological Institute of America (GIA). The GIA's revision aimed to align the list with modern gemological knowledge and market trends.
Ruby's association with Leo, the zodiac sign from July 23 to August 22, further cements its significance. In zodiac traditions, ruby is believed to enhance the traits of Leo, such as confidence, creativity, and leadership. It is also thought to amplify the positive qualities of other zodiac signs when worn by individuals who are compatible with its energies.
Geological Formation and Sources
Formation of Ruby
Ruby is a variety of the mineral corundum, which is aluminum oxide (Al₂O₃). The red color of ruby is primarily due to the presence of trace amounts of chromium or, less commonly, vanadium. The presence of these elements causes the characteristic red hue, with the most desirable color being a deep, vivid red known as "pigeon's blood."
Ruby forms in metamorphic rocks, particularly in marble and gneiss, which are created through the transformation of existing rock under high pressure and temperature. The formation process involves the interaction of corundum with mineral-rich fluids that introduce trace elements like chromium. The conditions necessary for ruby formation are relatively rare, contributing to the gemstone's scarcity and value.
Major Sources of Ruby
Myanmar (formerly Burma) is the most renowned source of high-quality ruby. The Mogok Stone Tract in Myanmar has been a significant source of ruby for centuries, producing the highly sought-after "pigeon's blood" rubies. These stones are prized for their intense red color and excellent clarity.
Other notable sources of ruby include:
Madagascar: Known for producing rubies with a slightly different hue, often more purplish or orange-red. The rubies from Madagascar are typically found in metamorphic rocks and are often cut in a variety of styles to showcase their color.
Thailand: Historically a major center for ruby trade and treatment. Thai rubies are often heat-treated to enhance their color and clarity, making them more affordable and accessible to a wider market.
Sri Lanka: Produces a range of ruby colors, from deep red to pinkish-red. Sri Lankan rubies are often found in alluvial deposits and are known for their clarity and brilliance.
Vietnam: In recent years, Vietnam has emerged as a significant source of ruby, particularly in the Luc Yen area. Vietnamese rubies are known for their vibrant color and good clarity.
The global ruby market is influenced by the availability and quality of stones from these sources. Factors such as political stability, mining regulations, and environmental concerns also impact the supply and demand of ruby.
Gemological Properties
Physical and Optical Characteristics
Ruby exhibits several distinctive gemological properties that contribute to its desirability and value:
Hardness: Ruby has a hardness of 9 on the Mohs scale, making it one of the hardest gemstones after diamond. This high hardness ensures that ruby is resistant to scratches and abrasion, making it suitable for use in various types of jewelry, including rings and bracelets.
Refractive Index: The refractive index of ruby ranges from 1.76 to 1.78. This means that ruby has a moderate to high refractive index, which contributes to its brilliance and fire. The refractive index is a measure of how light is bent as it passes through the gemstone, and a higher refractive index generally results in greater sparkle.
Specific Gravity: Ruby has a specific gravity of approximately 4.00. This is a measure of the gemstone's density relative to water and is useful in identifying and evaluating the stone. The specific gravity of ruby can vary slightly depending on the presence of other elements and inclusions.
Luster: Ruby has a vitreous (glassy) luster, which gives it a bright, shiny appearance. This luster is enhanced when the stone is properly cut and polished, allowing light to enter and reflect within the gemstone.
Inclusions: Like many gemstones, ruby often contains inclusions. These can include mineral inclusions, feathers, and silk. The presence of inclusions can affect the clarity and value of the stone. However, some inclusions are considered characteristic and can even enhance the beauty of the gemstone by creating a unique appearance.
Color and Treatment
The color of ruby is one of its most defining features. The most desirable ruby color is a deep, vivid red with a slight blue secondary hue, known as "pigeon's blood." This color is highly sought after and commands a premium price. Other ruby colors include pinkish-red, orangy-red, and purplish-red, each with its own appeal and market value.
Ruby is often heat-treated to enhance its color and clarity. Heat treatment is a common and accepted practice in the gemstone industry and can significantly improve the appearance of a ruby. The treatment involves heating the stone to high temperatures to remove impurities and enhance the red color. In some cases, rubies may also be treated with glass fillers to improve their clarity, although this is less common and can affect the value of the stone.
Symbolism and Metaphysical Beliefs

In ancient times, ruby was thought to bring courage, strength, and protection to the wearer.
In medieval Europe, ruby was believed to have protective properties and was used in amulets to ward off evil spirits and diseases.

Care and Cleaning
Maintenance and Cleaning Tips
Due to its high hardness, ruby is relatively easy to care for and can be worn in various types of jewelry. However, it is important to take certain precautions to ensure the longevity and beauty of the gemstone.
Avoid Harsh Chemicals: Ruby should be kept away from harsh chemicals, including household cleaners, perfumes, and cosmetics. These substances can dull the gemstone's surface and potentially damage the setting.
Use Gentle Cleaning Methods: To clean ruby jewelry, use a soft, lint-free cloth and mild soap. Gently wipe the gemstone and jewelry to remove any dirt or grime. Avoid using ultrasonic cleaners or steam cleaners, as these can potentially damage the gemstone or the setting.
Store Properly: When not in use, store ruby jewelry in a separate compartment or pouch to prevent scratches from other gemstones or jewelry. Avoid exposing the gemstone to extreme temperatures or humidity, as this can affect its color and clarity.
Regular Inspection: Have ruby jewelry inspected by a professional jeweler periodically to check for any signs of wear or damage. This is particularly important for rings and other pieces that are worn frequently.
Avoid Impact and Pressure: Although ruby is a durable gemstone, it can still be chipped or cracked if subjected to hard impacts or excessive pressure. Avoid wearing ruby jewelry during activities that involve physical contact or where the gemstone could be exposed to rough handling.
