We will also delve into its use in jewelry, care instructions, and the metaphysical beliefs associated with it. The ruby, with its fiery brilliance and storied past, remains a timeless treasure for those who wear it—and especially for those born on July 22nd.
History and Lore of the Ruby
The ruby has long been revered across civilizations, often associated with power, protection, and divine favor. Ancient cultures believed the ruby to be more than a gemstone—it was a source of life force and a guardian against misfortune. In India, for example, the ruby was known as ratnaraj, meaning “king of precious stones.” Indian royalty and warriors adorned themselves with rubies, believing the gemstone enhanced their vitality and strength.
In medieval Europe, rubies were thought to promote health and happiness, and some even believed the ruby could predict danger. This belief led to the practice of wearing rubies in battle or during travel as a protective charm. In Burmese culture, warriors carried rubies into combat, believing the stones made them invincible. These beliefs highlight the ruby’s perceived connection to both physical and spiritual strength.
The ruby’s association with blood and life has also contributed to its symbolic significance. In many cultures, the ruby was seen as a representation of the sun, with its vibrant red color mirroring the warmth and energy of the celestial body. In China, rubies were believed to bring good fortune and were often gifted during important celebrations. These historical uses and beliefs have cemented the ruby’s reputation as a gemstone of passion and power.
Geological Formation and Sources
The 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 the trace element chromium. Chromium is responsible for the ruby’s signature red color. The more chromium present in the corundum, the deeper and richer the red hue becomes. In some cases, a small amount of iron may also influence the color, resulting in secondary shades of pink, orange, or violet.
Geologically, rubies form under high-pressure and high-temperature conditions, typically within metamorphic rocks such as marble. Over time, these conditions cause the corundum to crystallize, and the presence of chromium gives rise to the ruby’s color. Once formed, rubies can be found in various geological environments, including alluvial deposits and gem gravels.
The most renowned sources of ruby are in Southeast Asia, particularly in Myanmar (formerly Burma). Burmese rubies are highly prized for their intense red color, often described as “pigeon’s blood”—a deep, vivid red with a slight purplish tone. Other notable ruby-producing countries include Thailand, Sri Lanka, Vietnam, and Madagascar. Each location produces rubies with distinct characteristics, often indicated by secondary color tones or fluorescence when exposed to sunlight.
The rarity of high-quality rubies, especially those with the ideal “pigeon’s blood” color, contributes to their value. In the gem trade, rubies with large sizes and exceptional color command extraordinary prices. Some of the most famous rubies in history, such as the Timor Ruby and the Black Prince’s Ruby, have been the subject of fascination and admiration for centuries.
Gemological Properties
From a gemological perspective, the ruby is one of the most durable and desirable gemstones available. On the Mohs Hardness Scale, which measures a mineral’s resistance to scratching, the ruby ranks at 9 out of 10. This high hardness makes it suitable for everyday wear in jewelry, as it is resistant to scratches and abrasions. However, while it is hard, the ruby is not completely impervious to damage. It can be susceptible to chipping or cracking if struck with sufficient force, particularly along any cleavage planes that may exist in the crystal structure.
The ruby’s refractive index is approximately 1.76 to 1.78, which means it bends light effectively, contributing to its brilliance and fire. Its specific gravity ranges from 3.95 to 4.03, making it a relatively dense gemstone. The ruby is typically transparent to translucent, and inclusions—small internal features that form during the crystal’s growth—are common. These inclusions can serve as identifying characteristics and are often used by gemologists to determine the origin of a ruby.
In terms of cut, rubies are often fashioned into brilliant cuts, such as the round brilliant or cushion cut, to maximize their sparkle. However, they can also be cut into other shapes, including oval, emerald, and pear shapes, depending on the desired aesthetic. The cut not only affects the gemstone’s appearance but also its value. A well-cut ruby will display optimal color and brilliance, while a poorly cut stone may appear dull or overly dark.
Rubies are available in a range of colors, from deep red to pinkish-red and even slightly purplish tones. The most valuable and sought-after color is the “pigeon’s blood” red, which is associated with Burmese rubies. The presence of a slight purple undertone is often considered a sign of high quality, as it adds depth and complexity to the color.
Symbolism and Metaphysical Beliefs
The ruby’s symbolism is deeply rooted in its color and its historical associations. Across cultures, it has been linked to love, passion, and vitality. In many traditions, rubies were believed to enhance the life force and promote a sense of well-being. Ancient healers and spiritual practitioners used rubies as talismans to ward off negative energies and to encourage courage and strength.
In modern metaphysical beliefs, rubies are often associated with the heart chakra and the root chakra. It is believed that the ruby can stimulate the heart chakra, promoting love and compassion, while also grounding the wearer by strengthening the root chakra. This dual influence makes the ruby a powerful stone for emotional and physical healing.
Ruby is also thought to enhance confidence and assertiveness, making it a popular choice for those seeking to overcome fear or self-doubt. It is said to encourage a sense of purpose and direction, helping individuals to stay focused on their goals. In some traditions, rubies are believed to bring good fortune and to protect against harm. These beliefs, while not scientifically proven, continue to shape the ruby’s appeal as both a gemstone and a symbol of positive energy.
In the context of birthstones, the ruby is particularly significant for those born on July 22nd. As the birthstone for this date, it is believed to offer its wearer the qualities of passion, protection, and vitality. Those who wear ruby jewelry may feel a sense of empowerment and connection to their inner strength, making it a meaningful and powerful choice.
Ruby in Jewelry: Design and Usage
Given its durability and vibrant color, the ruby is a popular choice for a wide range of jewelry designs. It is commonly used in rings, earrings, pendants, and bracelets, and is especially favored for engagement rings and anniversary pieces. The ruby’s deep red color makes it a striking centerpiece in jewelry, and it pairs well with both yellow and white gold, as well as platinum.
When designing ruby jewelry, it is important to consider the gemstone’s properties and potential vulnerabilities. While rubies are hard, they can still be damaged if exposed to sudden impacts or extreme temperatures. Therefore, they are best suited for everyday wear in settings that provide adequate protection. For example, a ruby set in a secure, metal bezel is less likely to be chipped or cracked than one set in a more delicate prong setting.
In addition to traditional jewelry, rubies are also used in more unconventional designs, such as inlays or as accent stones. Their rich color can add depth and contrast to pieces that feature other gemstones or metals. In some cultures, uncut rubies are used as healing crystals or incorporated into decorative objects, such as pendants or amulets.
When selecting ruby jewelry, it is important to consider the quality of the gemstone. Factors such as color, clarity, cut, and carat weight all contribute to the stone’s value and appearance. A well-cut ruby with a deep, even color and minimal inclusions is generally considered the highest quality. It is also important to verify the origin of the ruby, as certain sources—such as Myanmar—are known for producing the finest examples of the gemstone.
Care and Maintenance of Ruby Jewelry
Due to its high hardness, ruby is relatively easy to care for compared to other gemstones. However, proper maintenance is still essential to preserve its beauty and longevity. To clean ruby jewelry, it is recommended to use a soft brush, such as a toothbrush, and warm, soapy water. Gently scrub the gemstone and its setting, then rinse thoroughly and dry with a lint-free cloth.
It is important to avoid using harsh chemicals or ultrasonic cleaners, as these can damage the ruby or its setting. Additionally, rubies should not be exposed to extreme temperatures or sudden temperature changes, as this can cause stress within the crystal structure. Storing ruby jewelry in a separate compartment or pouch can help prevent scratches from other gemstones or metals.
When wearing ruby jewelry, it is advisable to remove it during activities that may subject it to impact or abrasion, such as sports or heavy manual work. While rubies are durable, they can still be chipped or cracked if struck with sufficient force. By following these simple care guidelines, ruby jewelry can remain beautiful and intact for generations.
