Ruby, the official birthstone for the entire month of July and a special gem for those born on the 25th, is more than just a jewel. It is a symbol of freedom, passion, and vitality. Historically revered as a stone of nobility and protection, ruby has been cherished across cultures for its beauty and spiritual significance. This article explores the ruby’s rich history, geological properties, cultural meanings, and care requirements, providing a comprehensive overview for gemstone enthusiasts, jewelry buyers, and students of gemology alike.
History and Lore
The ruby’s journey through history is as vibrant as its color. Known as the “king of gems,” ruby has long been associated with power, vitality, and protection. Ancient civilizations, from India to Egypt, revered this gemstone for its deep red hue, which they believed symbolized lifeblood and the sun’s energy.
Ancient and Medieval Associations
Ruby’s allure dates back to antiquity, where it was considered a divine gift. In ancient India, ruby was known as ratnaraj, meaning “king of precious stones.” It was believed to bring prosperity and protection to its wearer, often set into royal regalia and weapons. The Greeks and Romans associated ruby with the planet Mars, the god of war, and believed it could enhance courage and strength in battle. Roman soldiers wore ruby talismans to ensure victory and to shield themselves from harm.
During the Middle Ages, ruby was considered a stone of the heart, believed to promote love and passion. It was also used in religious ceremonies and was often included in the adornments of clergy and nobility. Medieval Europeans believed ruby could purify the blood and protect against poison, a belief that persisted for centuries.
The Modern Era and Birthstone Designation
The ruby’s designation as the July birthstone is relatively modern. The practice of assigning gemstones to months of the year has roots in ancient texts, including the biblical Breastplate of Aaron and the foundation stones of New Jerusalem. However, the contemporary system of birthstones was formalized in the early 20th century by the American National Association of Jewelers (now CBA – formerly Jewelers of America).
Ruby has been the official birthstone for July since 1912, and for those born on July 25th, it holds special significance. It is often paired with other July birthstones, such as carnelian and onyx, which were historically used in alternative traditions. In some cultures, ruby is considered a zodiac gemstone for those born under the sign of Cancer (June 21 – July 22), while carnelian is associated with Leo (July 23 – August 22).
Cultural and Spiritual Significance
Across different cultures, ruby has been imbued with various meanings and powers. In Hindu tradition, ruby is considered a sacred gemstone that represents the sun and is associated with the heart chakra. It is believed to bring energy, vitality, and spiritual awakening. In ancient China, ruby was used to ward off evil spirits and to bring good fortune. In the West, it was thought to bring protection, especially in times of danger or conflict.
The ruby also plays a role in metaphysical practices. It is believed to stimulate the base chakra, promoting grounding and vitality. Many spiritual traditions associate ruby with passion, courage, and emotional strength. Wearing ruby is said to enhance one’s inner fire and to inspire confidence and assertiveness.
Geological Formation and Sources
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 elements—specifically, chromium (Cr) and vanadium (V). These elements give ruby its characteristic red color. Chromium is the primary source of ruby’s red hue, while vanadium can create a slightly pinkish or purplish tone.
Formation Process
Ruby forms in metamorphic rocks, particularly in marble, under high-pressure and high-temperature conditions. The presence of chromium or vanadium in the surrounding environment is essential for the development of ruby’s color. The gemstone is often found in alluvial deposits, where it is eroded from its original formation site and transported by water, settling in gravels and sediments.
The most prized ruby deposits are found in Myanmar (formerly Burma), where the gemstone has been mined for centuries. These rubies are known for their intense red color and excellent fluorescence. Other notable sources include Thailand, Sri Lanka, Tanzania, and Madagascar. Each of these regions produces ruby with slightly different characteristics, influenced by the geological conditions of the area.
Ruby in Jewelry and Industry
Due to its hardness and durability, ruby is highly valued in the jewelry industry. It ranks 9 on the Mohs scale of mineral hardness, second only to diamond. This makes it suitable for use in rings, bracelets, and other pieces that are worn daily. Ruby is often cut into brilliant shapes to maximize its refractive properties and to showcase its deep red color.
Beyond its use in jewelry, ruby has also been used in industrial applications. Its hardness and resistance to wear make it useful in precision instruments and as a material for laser crystals. Ruby lasers, for example, were among the first lasers developed in the 20th century and are still used in certain specialized applications.
Gemological Properties
Ruby’s allure is not only due to its beauty but also its unique gemological properties. These properties define its value, durability, and suitability for different uses.
Color and Clarity
The most defining characteristic of ruby is its color. The finest rubies display a deep, vivid red known as "pigeon’s blood," a term used to describe a specific hue that is both intense and slightly purplish. This color is highly prized in the gem trade and commands premium prices. The presence of inclusions, or internal flaws, is also a factor in ruby’s value. While some inclusions are natural and can indicate the stone’s origin, excessive inclusions can reduce clarity and, therefore, the stone’s value.
Hardness and Durability
Ruby’s hardness of 9 on the Mohs scale makes it one of the hardest naturally occurring gemstones. This hardness contributes to its durability and makes it suitable for use in everyday jewelry. However, ruby has a perfect cleavage, meaning it can be split along specific planes if struck with sufficient force. This characteristic makes it important to handle ruby with care, especially when setting it into jewelry.
Cut and Shape
Ruby is typically cut in brilliant or step cuts to enhance its color and sparkle. The brilliant cut is used to maximize the stone’s refractive properties and to create the illusion of greater size. Step cuts, on the other hand, are used to showcase the gemstone’s color and to create a more elegant appearance. The choice of cut depends on the stone’s natural shape and the desired effect.
Carat Weight and Market Value
The value of a ruby is determined by several factors, including its color, clarity, cut, and carat weight. Larger rubies are more rare and, therefore, more valuable. However, the most expensive rubies are those with the finest color and minimal inclusions. The price of ruby can vary widely, with high-quality stones commanding prices in the thousands of dollars per carat.
Symbolism and Metaphysical Beliefs
Ruby is more than just a gemstone; it is a symbol of power, passion, and vitality. Across cultures and eras, ruby has been associated with various meanings and metaphysical properties.
Passion and Vitality
Ruby is often associated with passion and vitality. Its deep red color is reminiscent of the lifeblood and the energy of the heart. In many traditions, ruby is believed to enhance one’s vitality and to stimulate the body’s natural energy. It is said to bring courage and strength, especially in times of challenge or adversity.
Protection and Strength
Ruby is also considered a protective stone. It is believed to shield the wearer from negative energies and to provide a sense of security and confidence. In some cultures, ruby was used to protect against poison and illness. It was also worn by warriors and leaders to enhance their strength and to ensure victory in battle.
Love and Devotion
Ruby is often associated with love and devotion. It is considered a symbol of deep, enduring love and is frequently used in engagement and wedding rings. In many traditions, ruby is believed to promote harmony in relationships and to strengthen bonds between lovers.
Spiritual Awakening
Ruby is also linked to spiritual awakening. In some spiritual traditions, it is believed to stimulate the heart chakra and to bring about a sense of emotional balance and well-being. It is said to promote self-awareness and to help individuals connect with their inner truth.
Care and Cleaning
Due to its hardness and durability, ruby is a relatively easy gemstone to care for. However, there are certain precautions that should be taken to ensure its longevity and beauty.
Cleaning Methods
Ruby can be cleaned with warm, soapy water and a soft brush. It is important to avoid using harsh chemicals or abrasive cleaners, as these can damage the gemstone or its setting. Ultrasonic cleaners can be used with caution, as they may not be suitable for all types of ruby or settings.
Storage and Handling
Ruby should be stored in a soft cloth or a jewelry box to prevent scratches. It is also important to avoid exposing ruby to extreme temperatures or sudden temperature changes, as these can cause the gemstone to crack or fracture.
Professional Maintenance
For more delicate pieces or for stones with inclusions, it is advisable to have ruby professionally cleaned and inspected by a jeweler. Regular maintenance can help ensure that the gemstone remains in excellent condition and that any potential issues are addressed promptly.
