Ruby, the vibrant red gemstone, holds a revered place in the world of birthstones as the official birthstone for July. Known for its intense red color, symbolic significance, and historical prestige, ruby has captivated humans for centuries. As the "king of precious stones" in ancient India and a gem of choice for warriors and royalty, ruby is not only a symbol of vitality and love but also a gem of remarkable geological and cultural importance.
This article explores the ruby birthstone in depth, covering its historical significance, geological properties, symbolic meaning, and practical considerations for care and use. Drawing from reliable sources, including the Gemological Institute of America and modern birthstone guides, we will uncover the enduring allure of this precious gemstone.
History and Lore of the Ruby Birthstone
The ruby has long been cherished for its striking red color and association with power, vitality, and love. Its name comes from the Latin word ruber, meaning "red," and in ancient times, the gem was often referred to as the "king of precious stones." In India, ruby was believed to bring protection, health, and prosperity to the wearer, and it was highly valued for its rarity and hardness—second only to diamond.
The ruby's association with July as a birthstone dates back to the early 20th century. While many months have only one official birthstone, July is unique in that it has two: ruby and onyx. This dual designation reflects the historical evolution of birthstone traditions. Modern birthstones, as we know them today, were officially recognized by the Jewelers of America in the 1950s. However, traditional birthstones, which were widely accepted in earlier centuries, include a broader range of gems. Onyx, for example, has been associated with July for centuries in various cultures, including Roman and European traditions.
The ruby’s red color has been linked to blood, vitality, and passion since ancient times. In some cultures, warriors carried rubies into battle, believing the gem would make them invincible. In medieval Europe, rubies were thought to bring health, wisdom, and success in love. These beliefs have contributed to the gem's enduring appeal and its designation as a meaningful birthstone.
While the ruby’s role as a birthstone is relatively modern, its historical significance is profound. The gem has been used in jewelry and ceremonial objects for millennia, and its association with strength, power, and love continues to this day.
Geological Formation and Sources of Ruby
Rubies are 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 the element chromium. The more chromium present, the deeper and more intense the red color. The finest rubies exhibit a deep red with a hint of purple, a color known in the trade as “pigeon’s blood.”
The formation of rubies requires specific geological conditions. Corundum typically forms in metamorphic rocks, where high pressure and temperature cause minerals to recrystallize. In the case of rubies, the presence of chromium during this process gives the gem its characteristic red hue. The most highly prized rubies are found in specific regions around the world, including:
- Myanmar (Burma): Known for producing some of the finest rubies in the world, particularly those with the coveted "pigeon’s blood" color.
- Madagascar: A significant source of high-quality rubies in recent decades, with large deposits discovered in the 1990s.
- India, Sri Lanka, Thailand, and Vietnam: These countries also produce rubies, though their quality and color can vary.
Rubies are generally found in alluvial deposits, where they have been transported by water from their original rock formations. This makes them easier to mine compared to rubies still embedded in their host rock. The rarity of fine-quality rubies contributes to their high value in the gemstone market.
Gemological Properties of Ruby
Ruby is a remarkable gemstone not only for its beauty but also for its physical and optical properties. Here are some key gemological characteristics of ruby:
- Chemical Composition: Aluminum oxide (Al₂O₃) with trace amounts of chromium (Cr) responsible for its red color.
- Hardness: 9 on the Mohs scale, second only to diamond. This makes ruby a durable gemstone suitable for everyday wear.
- Refractive Index: 1.76–1.78, with strong double refraction (birefringence), which can be observed under magnification.
- Specific Gravity: 3.99–4.05, meaning it is relatively dense for its size.
- Luster: Vitreous (glassy), with a brilliant sparkle when properly cut.
- Color: Ranges from pinkish red to deep crimson, with the most valuable being the "pigeon’s blood" color, a deep red with a slight purple undertone.
- Clarity: High-quality rubies can be nearly flawless, but inclusions are common and often accepted as part of their natural beauty.
- Cut: Rubies are typically cut in round, oval, or cushion shapes to maximize brilliance and color. The "pigeon’s blood" color is most vivid in these cuts.
Ruby's hardness and durability make it suitable for a variety of jewelry, including rings, earrings, and pendants. However, due to its refractive properties, ruby can exhibit color zoning—areas of varying color intensity—especially in larger stones. Skilled gem cutters can enhance the color and brilliance of a ruby by carefully orienting the stone during cutting.
Symbolism and Metaphysical Beliefs
Rubies have long been associated with powerful symbolism and metaphysical properties. Across cultures and centuries, the gem has been linked to love, passion, vitality, and protection.
In ancient India, ruby was considered a powerful talisman. It was believed to bring health, strength, and prosperity to the wearer, and it was often worn by warriors for protection in battle. In medieval Europe, rubies were thought to bring health, wisdom, and success in love. Some believed the gem could predict danger or misfortune and even cure inflammatory diseases.
The ruby is also associated with the heart chakra in modern metaphysical practices. It is believed to open the heart, enhance emotional energy, and promote compassion and love. Some people wear rubies to boost confidence, vitality, and courage.
In addition to its emotional and spiritual properties, ruby is often given as a gift for special occasions. It is the traditional gemstone for 15th and 40th wedding anniversaries, symbolizing enduring love and commitment. As the birthstone for July, ruby is also a meaningful gift for those born in this month, representing their vitality, passion, and inner strength.
Ruby Birthstone Jewelry and Care
Ruby is a popular choice for fine jewelry due to its beauty, durability, and symbolic meaning. It can be found in a wide range of jewelry pieces, including rings, necklaces, earrings, and bracelets. Each design highlights the gemstone's deep red color and brilliance.

Due to its hardness and durability, ruby can be worn daily in jewelry. However, it is important to take proper care of the gemstone to maintain its beauty over time. Rubies should be cleaned with mild soap and warm water, using a soft brush to remove dirt and debris. Ultrasonic and steam cleaners can also be used, but care should be taken to avoid exposing the gem to harsh chemicals or extreme temperatures.
Rubies can be damaged by impact, so it is important to store them separately from other gemstones to prevent scratches. When wearing ruby jewelry, it is also advisable to avoid activities that could cause physical damage, such as heavy lifting or contact with rough surfaces.
If a ruby becomes loose or damaged in a piece of jewelry, it is important to have it inspected and repaired by a professional jeweler. Regular inspections can help identify and address any issues before they become more serious.
