History and Lore
Ruby has a long and storied history, often linked to power, wealth, and divine favor. Its historical significance is reflected in the many cultures that have cherished it over the centuries.
Ancient Origins
The ruby’s history can be traced back to ancient times. According to sources, rubies were traded along China’s North Silk Road as early as 200 BCE. The Mogok region of Myanmar, now credited with the discovery of rubies around 2500 BCE, has long been a primary source of these gemstones.
In ancient India, ruby was called ratnaraj, meaning "king of gemstones." This title reflects the stone’s esteemed status in Indian culture, where it was believed to bring prosperity and protection. Hindu mythology associates ruby with the sun, a symbol of power and vitality.
The Roman calendar originally named July Quintilis, as it was the fifth month. It was later renamed July in honor of Julius Caesar, who was born in this month. Over time, July acquired a variety of birthstones, including ruby, which has been associated with the month since ancient times.
Ruby in Royalty and Power
Ruby has long been a symbol of royalty and nobility. British monarchs, Chinese emperors, and Asian kings have all valued ruby as a gemstone of power and prestige. In Europe, ruby was believed to offer protection to warriors and was often set into armor and weapons.
In ancient Russia, ruby was one of the birthstones associated with July, and sardonyx—another July birthstone—was regarded as a strong protective stone that radiated optimism and confidence.
Cultural Significance and Symbolism
Ruby is associated with a range of symbolic meanings across different cultures. In general, it is seen as a stone of passion, protection, and vitality. Some sources note that ruby is believed to stimulate the base chakra, promoting a sense of groundedness and energy.
In addition to ruby, other traditional and alternative July birthstones include carnelian, onyx, sardonyx, and sapphire. These stones have also been associated with various properties, such as courage, strength, and spiritual wisdom.
Geological Formation and Sources
Formation Process
Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). The red color of ruby is due to the presence of chromium, which replaces some of the aluminum atoms in the crystal structure. This element is responsible for the gemstone’s intense red hue, often described as "pigeon’s blood" when it achieves the perfect balance of color and clarity.
Ruby forms deep within the Earth’s crust under high pressure and temperature conditions. It is typically found in metamorphic rocks, such as marble, which have undergone intense geological processes. The presence of trace elements like iron and titanium can affect the color and clarity of ruby, resulting in variations in its appearance.
Major Sources
Myanmar (formerly Burma) is the most historically significant source of ruby. The Mogok region, in particular, has been known for producing some of the finest rubies in the world. These gemstones are often characterized by their deep red color and excellent clarity.
In addition to Myanmar, other notable sources of ruby include:
- Madagascar: Known for producing high-quality rubies with vibrant red hues.
- Thailand: Historically a major trading hub for rubies, though the country does not produce its own gemstones.
- Sri Lanka: Produces rubies with a slightly pinkish hue due to lower chromium content.
- Vietnam and Tanzania: Emerging sources of ruby, each with unique characteristics.
Rubies from different regions may vary in color and clarity, depending on the geological conditions in which they formed.
Gemological Properties
Color
The most distinctive feature of ruby is its red color, which is caused by the presence of chromium. The most valuable rubies have a deep, rich red color often described as "pigeon’s blood." This term refers to a specific hue that is both intensely red and slightly bluish in tone, giving the gemstone a vibrant and lively appearance.
The color of ruby can also vary depending on the concentration of chromium and other trace elements. Some rubies may have a pinkish or purplish tint, while others may appear more orange or brownish.
Hardness and Durability
Ruby ranks 9 on the Mohs scale of hardness, making it one of the hardest gemstones after diamond. This high hardness makes ruby highly durable and suitable for use in a wide range of jewelry, including rings and bracelets that are worn daily.
Despite its hardness, ruby is not impervious to damage. It has a cleavage, meaning that it can be fractured along specific planes if struck with enough force. Therefore, it is important to handle ruby jewelry with care, especially when cleaning or setting the gemstone.
Clarity
Rubies are often found with inclusions, which are natural imperfections that form during the gemstone’s growth. These inclusions can range from small needle-like crystals to larger, more visible flaws. In some cases, these inclusions can actually enhance the value of a ruby by proving its authenticity.
The clarity of a ruby is graded based on the size, number, and visibility of these inclusions. A ruby with high clarity is considered more valuable, as it appears more transparent and "clean."
Cut and Shape
Ruby is commonly cut into various shapes, including round, oval, cushion, and emerald cuts. The choice of cut depends on the gemstone’s natural shape and the desired effect. A well-cut ruby will display maximum brilliance and color saturation.
The most popular cut for ruby is the round brilliant cut, which is designed to maximize the gemstone’s sparkle and color. However, step cuts like the emerald cut are also used to highlight the gemstone’s clarity and depth.
Carat Weight
Ruby is available in a wide range of carat weights, from small, delicate stones to large, statement pieces. The price of a ruby increases with carat weight, but the value also depends on other factors such as color, clarity, and cut.
Rubies weighing more than one carat are considered rare and valuable, especially if they have a deep red color and high clarity. Large rubies are often used in royal jewelry and high-end collections.
Chemical Composition
Ruby is composed primarily of aluminum oxide (Al₂O₃), with chromium (Cr) as the primary coloring agent. Trace amounts of other elements, such as iron and titanium, can also be present and may affect the gemstone’s color and appearance.
Refractive Index
The refractive index of ruby ranges from 1.76 to 1.78, which is relatively high compared to other gemstones. This high refractive index contributes to ruby’s brilliance and sparkle, making it a visually striking gemstone.
Symbolism and Metaphysical Beliefs
Ruby has long been associated with a range of symbolic and metaphysical meanings. Across cultures and centuries, it has been regarded as a stone of power, vitality, and protection.
Passion and Energy
Ruby is often linked to passion and energy. It is believed to ignite a sense of vitality and courage in the wearer, making it a popular choice for those seeking motivation and inspiration. In many cultures, ruby is associated with love and is considered a symbol of deep affection and devotion.
Protection and Strength
Historically, ruby has been used as a protective talisman. Warriors and royalty often wore ruby to ward off negative energies and ensure strength and success in battle. Some sources mention that ruby was believed to provide protection and enhance one’s sense of power and confidence.
Spiritual and Healing Properties
In metaphysical practices, ruby is associated with the base chakra, which is linked to grounding and stability. It is believed to promote vitality and energy, helping the wearer feel more connected to the physical world. Some sources also suggest that ruby can enhance emotional balance and bring a sense of inner strength.
In Hindu mythology, ruby is considered a divine gemstone that brings prosperity and spiritual wisdom. It is also believed to have healing properties, particularly for the heart and circulatory system.
Care and Cleaning
Due to its high hardness and durability, ruby is relatively easy to care for compared to other gemstones. However, it is still important to follow proper cleaning and maintenance practices to preserve its beauty and longevity.
Cleaning Methods
Ruby can be cleaned using warm, soapy water and a soft brush. Gently scrub the gemstone to remove dirt and debris, then rinse it thoroughly with water. Avoid using harsh chemicals or abrasive materials, as they can damage the gemstone’s surface.
Steam cleaning and ultrasonic cleaning are also safe methods for cleaning ruby, provided that the gemstone does not have any inclusions that could be affected by high heat or vibration.
Storage and Handling
When not being worn, ruby jewelry should be stored in a soft cloth or a jewelry box to prevent scratches and damage. It is best to store ruby separately from other gemstones, as harder stones can scratch the surface of ruby.
Avoid exposing ruby to extreme temperatures or sudden temperature changes, as this can cause the gemstone to crack or fracture. It is also advisable to remove ruby jewelry before engaging in activities that could subject it to impact or pressure.
Repair and Maintenance
If ruby jewelry requires repair or re-setting, it should be handled by a professional jeweler. Due to ruby’s hardness and potential for cleavage, it is important to use proper techniques and tools to avoid damaging the gemstone.
Conclusion
The ruby, with its deep red color and rich history, remains one of the most cherished gemstones in the world. As the birthstone for July, it symbolizes passion, vitality, and protection.
