History and Lore
Ruby’s history is as rich and storied as the gemstone itself. Referred to as the "king of gems" in many ancient cultures, ruby has been treasured across continents and eras for its beauty and symbolic power. The gemstone has appeared in the crown jewels of monarchs, adorned sacred artifacts, and been the subject of myth and legend.
The name "ruby" originates from the Latin word ruber, meaning "red." In Sanskrit, ruby is called ratnaraj, or "king of precious stones," and padmaraga, which means "the color of a lotus." These names reflect the deep cultural reverence for ruby in ancient India and South Asia. In medieval Europe, ruby was believed to possess protective and healing properties. It was thought to ward off evil spirits, bring good fortune, and even cure ailments.
One of the earliest references to ruby comes from the Roman naturalist Pliny the Elder, who described the gem in the first century AD. He noted that ruby was believed to be created by fire from the heavens or by lightning strikes, a belief that led to its alternative name in Germany, Donnerkeil, meaning "thunderbolt." In the 19th century, French poet and gemologist Jean-Baptiste Tavernier wrote about ruby in his work Lapidaire en Vers, where he celebrated its divine status and its role in sacred rituals.
In ancient times, ruby was primarily sourced from Burma (modern-day Myanmar), which was the world’s leading producer for centuries. The Burmese monarchy tightly controlled ruby mining, and the gemstone was considered a symbol of royal power. The Burmese king was even referred to as the "Lord of Rubies," and miners were required to surrender large gems to the crown. This monopoly on ruby production contributed to the gem’s mystique and value.
Ruby’s association with royalty and divinity continued into the modern era. The gem has been featured in royal regalia, including the British Crown Jewels and the jewelry of the Mughal emperors of India. In Hindu tradition, ruby is considered a sacred stone, and it is often associated with the zodiac sign Taurus. In some cultures, ruby is believed to represent the sun, a symbol of life, vitality, and energy.
Geological Formation and Sources
Ruby belongs to the corundum family of minerals, which is composed primarily of aluminum oxide (Al₂O₃). What distinguishes ruby from other corundum varieties is the presence of trace amounts of chromium, which gives it its characteristic red color. The intensity of the red hue depends on the concentration of chromium and the presence of other trace elements. The most valuable rubies display a pure red or slightly purplish-red color, often described as "pigeon's blood."
Ruby forms under extreme geological conditions, typically in metamorphic rocks such as marble or in igneous rocks like basalt. The formation process requires high pressure and high temperature, often at depths of several kilometers within the Earth's crust. Ruby is often found in association with other gemstones such as sapphire and zircon, and its formation is closely tied to tectonic activity and the movement of magma.
Historically, the most significant ruby deposits were located in Burma (Myanmar), particularly in the Mogok Valley. This region was the primary source of the world's finest rubies for centuries. The Mogok Valley's ruby deposits are found in metamorphic rocks that formed over millions of years through the collision of tectonic plates. The region’s geological history has contributed to the formation of high-quality rubies with exceptional color and clarity.
In addition to Burma, ruby is also found in other parts of the world, including Thailand, Sri Lanka, Afghanistan, and more recently, Mozambique and Tanzania. In Thailand, ruby deposits are primarily found in the Chanthaburi and Trat provinces, where rubies are often accompanied by other corundum varieties. Sri Lanka has been a significant source of ruby since around 800 BC, with the gemstone being traded along the ancient Silk Road. The Jegdalek mines in Afghanistan have also produced notable ruby specimens, particularly in the 20th century.
The discovery of new ruby deposits in Africa, particularly in Mozambique and Tanzania, has expanded the global supply of ruby in recent decades. These African rubies are often more affordable than their Burmese counterparts, making them more accessible to jewelry consumers. Despite the availability of rubies from these new sources, Burmese rubies remain highly prized for their exceptional color and historical significance.
Lab-grown ruby, first introduced in the early 20th century, has also become a popular alternative to natural ruby. These synthetic rubies are created using advanced techniques such as the flame-fusion and hydrothermal methods, which replicate the natural formation process in a controlled environment. Lab-grown ruby often exhibits better clarity and more consistent color than natural ruby, making it a cost-effective option for jewelry. However, many collectors and connoisseurs still prefer natural ruby for its unique characteristics and geological history.
Gemological Properties
Ruby is one of the hardest and most durable gemstones, second only to diamond on the Mohs Hardness Scale. With a rating of 9, ruby is well-suited for everyday wear and can withstand the rigors of daily use. This durability makes ruby an excellent choice for rings, necklaces, and other types of fine jewelry. However, while ruby is hard, it can still be damaged if exposed to extreme heat or subjected to a hard impact. Careful handling and proper cleaning are essential for maintaining the gemstone’s brilliance and longevity.
In addition to its hardness, ruby is known for its high refractive index, which gives it a brilliant sparkle. The gemstone exhibits strong pleochroism, meaning it can display different colors when viewed from different angles. This property is particularly noticeable in rubies with a purplish or orangish hue. The most valuable rubies are those with a pure red or slightly purplish-red color, often referred to as "pigeon's blood." This color is considered the ideal ruby hue and is highly sought after by collectors and jewelry connoisseurs.
Ruby’s chemical composition is primarily aluminum oxide, with trace amounts of chromium responsible for its red color. The presence of other trace elements can affect the gemstone’s color and clarity. For example, rubies with a higher concentration of iron may appear more orangish, while those with a higher concentration of vanadium may have a slightly purplish hue. The clarity of ruby can vary significantly, ranging from transparent to translucent. High-quality rubies with excellent clarity and color are rare and command high prices in the market.
Ruby is also known for its excellent luster, which is often described as vitreous or glassy. This luster enhances the gemstone’s brilliance and makes it a popular choice for jewelry. The way a ruby is cut also plays a crucial role in its appearance. The most common cuts for ruby include the emerald cut, round brilliant cut, and cushion cut. Each cut is designed to maximize the gemstone’s color and sparkle, ensuring that it looks its best in jewelry.
Symbolism and Metaphysical Beliefs
Ruby has long been associated with powerful symbolism and metaphysical properties. Across cultures and historical periods, ruby has been seen as a symbol of love, passion, protection, and vitality. In ancient times, ruby was believed to bring good fortune, ward off evil spirits, and even cure ailments. In medieval Europe, ruby was considered a protective stone that could shield the wearer from danger and illness. It was also believed to enhance courage, strength, and vitality.
In many cultures, ruby has been associated with the sun, a symbol of life, energy, and power. In Hindu tradition, ruby is considered a sacred stone and is often linked to the zodiac sign Taurus. It is believed to enhance confidence, assertiveness, and leadership qualities. In Chinese culture, ruby is associated with good luck and prosperity. It is often given as a gift to celebrate important life events, such as weddings and anniversaries.
Ruby is also deeply connected to the heart chakra in metaphysical traditions. It is believed to promote love, compassion, and emotional healing. Some modern sources suggest that ruby can help stimulate the circulatory system and increase vitality, though these claims are not widely accepted in formal gemology. Despite the lack of scientific evidence, many people continue to believe in the gemstone’s healing and metaphysical properties.
As a birthstone, ruby is often associated with those born in July. It is believed to bring protection, strength, and vitality to individuals born in this month. In some cultures, ruby is also used in jewelry as a symbol of commitment and enduring love. Engagement rings and wedding bands set with ruby are believed to promote lasting love and harmony in relationships.
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 handle ruby jewelry with care to prevent damage. Ruby should be protected from sudden temperature changes, as this can cause the gemstone to crack or fracture. It is also important to avoid exposing ruby to harsh chemicals, as these can dull its luster or cause damage to the gemstone.
To clean ruby jewelry, it is recommended to use a soft, lint-free cloth and warm, soapy water. A mild detergent such as dish soap can be used to gently clean the gemstone. After cleaning, the jewelry should be rinsed thoroughly with warm water and dried with a soft cloth. For more thorough cleaning, a professional jeweler can use an ultrasonic cleaner or steam cleaner, which are safe for ruby and can help restore its brilliance.
When storing ruby jewelry, it is best to keep it in a soft, padded pouch or a jewelry box with individual compartments to prevent scratches and damage. Ruby should be stored separately from other gemstones, particularly those with lower hardness, to avoid abrasion. It is also important to avoid exposing ruby to direct sunlight or heat sources for extended periods, as this can cause the gemstone to fade or become brittle.
For those who wear ruby jewelry regularly, it is a good idea to have it inspected by a professional jeweler periodically. This can help ensure that the gemstone remains secure in its setting and that the jewelry continues to look its best. Regular inspections can also help identify any potential issues, such as loose stones or wear on the metal setting.
