July is marked by warmth, vitality, and the radiance of summer, and these qualities are embodied in the gemstone chosen as its birthstone—ruby. Known as the “king of gemstones,” ruby is a symbol of passion, power, and protection. As the July birthstone, it holds a prominent place in both gemological and cultural history, admired for its fiery red color, exceptional durability, and enduring beauty.
This article explores the ruby in depth, covering its historical significance, geological formation, symbolic meanings, and its place in jewelry and birthstone traditions. The information is drawn exclusively from authoritative and verified sources to ensure accuracy and reliability.
History and Lore of the Ruby
The ruby has been treasured for thousands of years across cultures and civilizations. Ancient Indian and Chinese traditions revered the ruby not only for its beauty but also for its perceived mystical properties. In India, it was known as the “king of precious stones” and was believed to bring prosperity, vitality, and protection from harm. Warriors were said to wear ruby amulets into battle, believing the gemstone would grant them invincibility.
In medieval Europe, rubies were often associated with the blood of Christ and the life force of the human body. They were included in royal regalia and were symbols of divine favor, love, and power. Kings and queens adorned themselves with ruby-studded crowns and jewelry, believing that the gemstone enhanced their authority and connection to the divine.
The name “ruby” is derived from the Latin word ruber, meaning “red,” a clear reference to its striking color. This deep red hue has long been associated with blood, fire, and passion, making the ruby a fitting symbol of life and vitality. Some historical accounts even suggest that the ruby could predict danger or misfortune, adding to its allure and mystique.
In Burma (now Myanmar), where some of the finest rubies in the world are found, the gemstone has long been a part of cultural traditions. The Burmese believed that a ruby worn close to the heart would bring health and happiness. These beliefs have persisted over centuries and continue to influence the ruby’s symbolism in modern times.
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 trace amounts of the element chromium. It is this chromium content that gives ruby its characteristic red color. The more chromium present in the crystal structure, the deeper and more vibrant the red color becomes.
The finest rubies display a deep red with a slight purple hue, a color known in the trade as “pigeon’s blood.” This term, while somewhat subjective, refers to the most desirable and valuable coloration of ruby. The presence of other trace elements can also affect the color, sometimes giving rubies a pinkish or purplish tone, but the classic red remains the most sought-after.
Ruby forms under high-pressure, high-temperature conditions deep within the Earth’s crust. It is typically found in metamorphic rocks, where the transformation of existing minerals under intense heat and pressure leads to the crystallization of corundum. The process can take millions of years, contributing to the rarity and value of ruby.
The most famous source of ruby is Myanmar (Burma), particularly in the Mogok region. Burmese rubies are renowned for their exceptional color and quality. However, other significant ruby-producing regions include Thailand, Sri Lanka, Madagascar, Mozambique, and Afghanistan. Each of these sources produces rubies with unique characteristics, influenced by the local geology and mineral composition.
Rubies are one of the hardest gemstones, ranking 9 on the Mohs Hardness Scale, second only to diamonds. This high level of hardness makes them highly durable and suitable for everyday wear in jewelry. Despite their toughness, rubies can still be damaged by sudden impacts or exposure to harsh chemicals, and they require proper care to maintain their luster.
Gemological Properties of Ruby
Ruby is one of the four precious gemstones, alongside diamond, sapphire, and emerald. Its status as a precious gem is due to its rarity, beauty, and durability. Here are some key gemological properties of ruby:
- Chemical Composition: Aluminum oxide (Al₂O₃) with trace amounts of chromium.
- Hardness: 9 on the Mohs Hardness Scale.
- Refractive Index: 1.76–1.78.
- Specific Gravity: 3.95–4.05.
- Color: Red, with variations ranging from deep crimson to pinkish red. The most prized color is known as “pigeon’s blood.”
- Luster: Vitreous (glassy).
- Transparency: Transparent to translucent.
- Inclusions: Common in natural rubies, often referred to as “silk” when they appear as fine, needle-like rutile crystals. These inclusions are considered natural proof of a ruby’s authenticity and are often admired for their beauty.
Rubies are cut in a variety of styles, including round, oval, emerald, and pear shapes. The most popular cut is the oval, which enhances the gemstone’s brilliance and color. Faceting is used to maximize light reflection and create a dazzling sparkle.
Ruby is a uniaxial gemstone, meaning it has a single optic axis. This property affects how light travels through the gem and contributes to its optical phenomena, such as pleochroism. Pleochroism refers to the ability of a gemstone to show different colors when viewed from different angles. In rubies, this can result in slight variations in color perception, adding to their visual complexity.
Symbolism and Metaphysical Beliefs
Ruby has long been associated with powerful symbolism and metaphysical properties. Across cultures and centuries, it has been regarded as a stone of vitality, protection, and emotional strength.
Symbol of Love and Passion
Ruby is often associated with love and passion, making it a popular choice for romantic jewelry. Its deep red color is a natural symbol of the heart and emotions, and it is believed to enhance feelings of love, devotion, and commitment. In many cultures, ruby has been used in engagement rings and wedding bands to symbolize enduring love and fidelity.
The gemstone is also associated with passion, not only in a romantic sense but also in terms of life force and energy. It is believed to invigorate the body and mind, bringing a sense of vitality and enthusiasm to the wearer. This makes ruby a powerful stone for those seeking motivation and inspiration.
Stone of Protection and Courage
Ruby has also been regarded as a protective stone, warding off negative energy and promoting courage and resilience. In ancient times, warriors and leaders wore ruby amulets to protect themselves in battle and to boost their strength and confidence. This belief in ruby’s protective power persists in some modern traditions.
Ruby is also associated with the sun, representing power, warmth, and life. It is believed to enhance one’s inner strength and ability to overcome challenges, making it a valuable stone for those facing difficult times.
Metaphysical Properties and Healing
In metaphysical practices, ruby is associated with the root chakra, which is linked to grounding, stability, and a sense of security. It is believed to help individuals feel more connected to the Earth and to their own inner strength. Ruby is also associated with the heart chakra, promoting love, compassion, and emotional healing.
Some traditions suggest that ruby can help with physical healing, particularly in relation to the circulatory system. It is believed to stimulate the flow of energy and blood, enhancing vitality and overall health. Ruby is also thought to help with conditions related to the heart, such as improving heart function and reducing stress.
While these metaphysical properties are not scientifically proven, they reflect the deep cultural and historical significance of ruby as a symbol of life, love, and strength.
Ruby in Jewelry and Modern Culture
Ruby’s enduring appeal has made it a popular gemstone in jewelry, especially as the July birthstone. Its vibrant color and durability make it ideal for a wide range of jewelry designs, from classic rings and pendants to modern fashion pieces.
Ruby is often used in engagement rings and wedding bands, where its deep red color symbolizes enduring love and commitment. It is also a popular choice for anniversary gifts, particularly for 40th anniversaries, where it is traditionally associated with the milestone.
In addition to its role as a birthstone, ruby is a symbol of luxury and elegance. It is often paired with diamonds and other precious gemstones to create striking combinations that highlight its brilliance and color. Ruby’s versatility allows it to be used in both traditional and contemporary designs, making it a timeless gemstone.

High-quality rubies, especially those with the coveted “pigeon’s blood” color, can command extremely high prices at auctions and in the luxury jewelry market.
Care and Cleaning of Ruby
Due to its high hardness and durability, ruby is relatively easy to care for compared to other gemstones. However, to maintain its brilliance and longevity, it is important to follow proper care and cleaning guidelines.
Cleaning
Ruby can be cleaned using a mild detergent and warm water. A soft brush, such as a toothbrush, can be used to gently remove dirt and debris from the gemstone and its setting. After cleaning, the gemstone should be rinsed thoroughly and dried with a soft cloth.
Avoid using harsh chemicals, abrasive cleaners, or ultrasonic cleaners, as these can damage the gemstone or its setting. Ruby can also be sensitive to sudden temperature changes, so it should be kept away from extreme heat or cold.
Storage
When not in use, ruby jewelry should be stored in a soft pouch or a jewelry box with individual compartments to prevent scratches and damage. It is also important to remove ruby jewelry before engaging in activities that may cause impact or abrasion, such as sports or manual labor.
Professional Maintenance
While ruby is durable, it is still a natural gemstone and may require periodic professional maintenance. Jewelers can inspect ruby jewelry for loose settings, wear and tear, and any signs of damage. Regular inspections can help ensure that the gemstone remains in excellent condition for years to come.
