The birthstone for July is the ruby, and for those born under the Cancer zodiac sign (June 21 – July 22), it holds a special place in both symbolism and historical tradition. As one of the most revered gemstones in the world, the ruby has long been associated with passion, power, and protection—qualities that align closely with the nurturing and emotional nature of Cancer.
This article delves into the rich history, gemological properties, cultural significance, and practical care of the ruby. Drawing from authoritative sources and historical records, it provides a comprehensive overview of why the ruby is not only a July birthstone but also a deeply meaningful gem for Cancer individuals.
History and Lore
The ruby has captivated humans for thousands of years, with evidence of its use dating back to ancient civilizations. The name "ruby" comes from the Latin word ruber, meaning "red," a fitting name for a gemstone renowned for its intense red hue. In ancient India, rubies were so highly valued that they were often referred to as the "king of precious stones." This title reflects not only their rarity and hardness—second only to the diamond—but also their deep cultural and spiritual significance.
In medieval Europe, the ruby was believed to symbolize the heart and was often associated with love, wisdom, and success. It was thought to bring good fortune and even to predict danger. Some legends suggested that if a ruby cracked or changed color, it was a sign of impending misfortune. In Burmese culture, warriors would wear rubies into battle, believing the stones made them invincible. These beliefs speak to the ruby’s enduring allure and its role as a powerful protective talisman.
For Cancer, the ruby is particularly meaningful. As a water sign ruled by the moon, Cancer is often described as emotional, intuitive, and nurturing. The ruby, with its vibrant red color and fiery energy, is believed to help Cancers connect with their emotional depth while also providing a sense of strength and stability. Ancient astrologers also associated the ruby with the sun, a celestial body that symbolizes vitality and life force—both of which are important for Cancers, who often seek emotional and physical comfort.
The ruby's role as a Cancer birthstone was officially recognized in the 20th century. The Jewelry Industry Council of America updated its birthstone list in 1952, adding the ruby as the official July birthstone. This decision was based on the gem's historical significance, its association with the sun, and its alignment with the traits of those born under the Cancer sign.
Geological Formation and Sources
Rubies are a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). What distinguishes a ruby from other corundum gems is the presence of the element chromium, which gives the gemstone its characteristic red color. The more chromium present in the crystal structure, the deeper and richer the red hue. The finest rubies, known as "pigeon blood" rubies, have a deep red color with a subtle hint of purple.
The formation of rubies occurs under high-pressure and high-temperature conditions deep within the Earth's crust. These conditions cause the aluminum oxide to crystallize into corundum. When trace amounts of chromium are present, the resulting gemstone becomes a ruby. The process can take millions of years, making natural rubies rare and highly valuable.
Ruby deposits are found in several parts of the world, but the most famous sources are in Myanmar (formerly Burma). Burmese rubies, particularly those from the Mogok region, are considered the finest in the world due to their exceptional color and clarity. Other notable ruby sources include Thailand, Sri Lanka, Tanzania, and Afghanistan. Each of these locations produces rubies with slightly different characteristics, such as variations in color tone and clarity.
The mining of rubies is a labor-intensive and often challenging process. Because of their formation in metamorphic rocks, ruby deposits are typically found in remote and difficult-to-reach areas. Miners must carefully extract the gemstones by hand to avoid damaging them. In recent years, synthetic rubies have been produced in laboratories, but natural rubies remain the most sought after for their rarity and beauty.
Gemological Properties
The ruby is one of the hardest gemstones, with a rating of 9 on the Mohs scale of mineral hardness. This high hardness makes it extremely durable and suitable for use in a variety of jewelry, including rings, bracelets, and pendants. However, like all corundum gems, rubies can have inclusions—tiny imperfections within the crystal structure. These inclusions are natural and often add character to the gemstone, but they can also affect its clarity and value.
One of the most remarkable features of the ruby is its color. The presence of chromium gives the gemstone a vibrant red hue, but the exact shade can vary depending on the concentration of chromium and the presence of other trace elements. The most prized rubies have a deep red color with a slight purplish tone, known as the "pigeon blood" color. This color is highly sought after in the gemstone market and commands premium prices.
Rubies also have a high refractive index, which contributes to their brilliance and fire. When cut properly, a ruby can display a dazzling sparkle that is both captivating and elegant. The most common cut for rubies is the emerald cut, which enhances the gemstone's color and clarity. However, other cuts such as round, oval, and cushion cuts are also used depending on the shape and size of the rough stone.
In terms of carat weight, rubies can range from small melee stones to large, over 100-carat gems. The largest ruby in the world is the "Timberline Ruby," which weighs 13,125 carats (2.625 carats). However, the value of a ruby is not solely determined by its size. Color, clarity, and origin are equally important factors in assessing a ruby's worth.
Symbolism and Metaphysical Beliefs
Throughout history, the ruby has been associated with a wide range of symbolic meanings. In many cultures, it is seen as a symbol of love, passion, and vitality. The deep red color of the ruby is often linked to the heart, and the gemstone is believed to promote emotional warmth and connection. For Cancers, who are known for their emotional sensitivity and nurturing nature, the ruby can serve as a powerful ally in expressing and embracing their feelings.
In addition to its associations with love, the ruby is also considered a stone of protection. Ancient warriors believed that wearing a ruby in battle would make them invincible, while medieval Europeans thought that the gemstone could predict danger and ward off misfortune. In Feng Shui, rubies are used to enhance personal power and confidence, making them particularly beneficial for those who may struggle with self-esteem or assertiveness.
From a metaphysical perspective, the ruby is believed to stimulate the root chakra, which is associated with grounding, stability, and a sense of security. This makes the ruby an excellent gemstone for Cancers, who often seek comfort and emotional safety. It is also thought to enhance vitality and energy, helping individuals to feel more empowered and motivated in their daily lives.
Modern crystal healers recommend rubies for their ability to balance emotions and promote a sense of inner strength. They believe that the ruby can help individuals overcome fear and anxiety, making it a valuable tool for those who are going through difficult times. For Cancers, who are often deeply emotional and sensitive, the ruby can provide a sense of emotional balance and resilience.
Care and Cleaning
Due to its high hardness and durability, the ruby is a relatively easy gemstone to care for. However, like all gemstones, it requires proper maintenance to ensure its beauty and longevity. Because rubies can have inclusions, it is important to avoid using harsh chemicals or abrasive materials when cleaning them. These can damage the surface of the gemstone or cause microfractures to widen over time.
The best way to clean a ruby is with warm, soapy water and a soft cloth or brush. A mild dish soap is usually sufficient for removing dirt and grime. After cleaning, the gemstone should be rinsed thoroughly with warm water and dried with a soft, lint-free cloth. For more stubborn stains, a professional jeweler can provide a steam or ultrasonic cleaning service, which is safe for most ruby jewelry.
When storing ruby jewelry, it is important to keep it in a cool, dry place away from direct sunlight. Prolonged exposure to sunlight can cause the gemstone to fade or lose its luster over time. Rubies should also be stored separately from other gemstones to prevent scratches, as even the hardest gemstones can be damaged by contact with harder materials.
For Cancers who wear ruby jewelry regularly, it is also a good idea to periodically have the gemstone inspected by a professional jeweler. This can help to identify any potential issues such as loose settings or damage to the gemstone. Regular inspections can also help to ensure that the ruby remains in excellent condition for many years to come.
