Introduction
The ruby, a member of the corundum family, is more than just a gemstone; it is a symbol of passion, protection, and prosperity. With a hardness of 9 on the Mohs scale, it is one of the hardest naturally occurring gemstones, second only to diamond. The ruby is found in various parts of the world, with the most prized stones coming from Myanmar (formerly Burma). Historically, the ruby has been associated with power and divine favor, often worn by royalty and leaders. Its deep red hue, often described as "pigeon's blood," is highly sought after in the jewelry market.
This article delves into the ruby's geological formation, historical uses, cultural symbolism, and practical care, providing a comprehensive overview for gemstone enthusiasts, jewelry buyers, and students of gemology.
History and Lore
The ruby has a rich and storied history that spans centuries and civilizations. Ancient cultures revered the ruby for its beauty and believed it possessed mystical properties. In ancient India, the ruby was considered the "King of Precious Stones" and was believed to bring protection and prosperity to its wearer. Indian texts from as early as the 6th century AD describe the ruby as a stone that could ward off evil and bring good fortune.
In medieval Europe, the ruby was associated with the blood of Christ and was believed to have healing properties. It was also thought to enhance vitality and provide protection against disease. European royalty often wore rubies as a symbol of power and divine right. The ruby's red color was seen as a symbol of life and vitality, making it a popular choice for crowns and regalia.
During the 18th and 19th centuries, the ruby's popularity continued to grow, especially with the discovery of new sources in Sri Lanka, Thailand, and Vietnam. These new deposits made the ruby more accessible and affordable, allowing it to become a popular gemstone for both royal and common use.
In modern times, the ruby has been celebrated in literature, art, and film. It is often depicted as a symbol of passion and love, and its deep red color has been associated with romance and desire. The ruby's enduring appeal is a testament to its rich history and the many cultures that have cherished it over the centuries.
Geological Formation and Sources
The ruby is a corundum gemstone, which means it is composed primarily of aluminum oxide (Al₂O₃). What distinguishes a ruby from other corundum varieties, such as sapphires, is the presence of trace amounts of chromium, which gives the ruby its characteristic red color. The more chromium present in the stone, the deeper the red hue becomes.
Rubies are formed deep within the Earth's crust through a process of metamorphism. This occurs when aluminum-rich rocks are subjected to intense heat and pressure, causing the minerals to recrystallize into new forms. In the case of rubies, the presence of chromium during this process is crucial to the development of their red coloration.
The most famous and highly prized rubies come from Myanmar (formerly Burma). Burmese rubies are known for their "pigeon's blood" color, a term used to describe the perfect red hue with a slight blue undertone. These rubies are found in the Mogok Stone Tract, a region that has been a major source of rubies for centuries.
Other significant sources of rubies include Thailand, Vietnam, Sri Lanka, Tanzania, and Madagascar. Each of these regions produces rubies with slightly different characteristics, such as color intensity, clarity, and overall quality. For example, Thai rubies often have a darker red color due to higher iron content, while Sri Lankan rubies tend to have a lighter, more pinkish hue.
The ruby's hardness of 9 on the Mohs scale makes it highly durable and suitable for use in jewelry. However, rubies can have inclusions and may exhibit cleavage, which means they can be prone to chipping if not handled carefully. This is why proper care and handling are essential to preserving the beauty and integrity of a ruby gemstone.
Gemological Properties
The ruby's gemological properties are a key factor in its value and desirability. As a corundum gemstone, the ruby has a hardness of 9 on the Mohs scale, making it one of the hardest naturally occurring gemstones. This high hardness allows rubies to be used in a wide range of jewelry designs, including rings, necklaces, and earrings.
The ruby's refractive index ranges from 1.76 to 1.78, which gives it a brilliant and sparkling appearance when cut and polished. The most valuable rubies are those that exhibit a deep red color with a slight blue undertone, often referred to as "pigeon's blood." This color is a result of the presence of chromium in the stone's composition.
Clarity is another important factor in determining the value of a ruby. High-quality rubies are typically free of visible inclusions, but some inclusions are natural and can be used to distinguish natural rubies from synthetic ones. The presence of inclusions does not necessarily detract from a ruby's beauty, as many collectors and jewelers appreciate the unique character that these inclusions add.
The carat weight of a ruby also affects its value. Larger rubies are rarer and more valuable, but the overall quality of the stone, including color, clarity, and cut, is the most important factor in determining its worth. A well-cut ruby will enhance the stone's color and brilliance, making it more visually appealing and valuable.
Rubies can be found in a variety of colors, although the most prized are the deep red stones with a slight blue undertone. Other colors, such as pinkish red or orangish red, are also available but are generally less valuable. The ruby's versatility in color and its high durability make it a popular choice for both traditional and modern jewelry designs.
Symbolism and Metaphysical Beliefs
Throughout history, the ruby has been associated with a wide range of symbolic meanings and metaphysical beliefs. In many cultures, the ruby has been seen as a symbol of passion, protection, and prosperity. Its deep red color has been linked to the heart and emotions, making it a popular choice for romantic jewelry.

Indian texts describe the ruby as a stone that could ward off evil and bring good fortune. This belief in the ruby's protective properties continued through the centuries and is still held by many today.
In medieval Europe, the ruby was associated with the blood of Christ and was believed to have healing properties. It was also thought to enhance vitality and provide protection against disease. European royalty often wore rubies as a symbol of power and divine right. The ruby's red color was seen as a symbol of life and vitality, making it a popular choice for crowns and regalia.
Modern metaphysical beliefs about the ruby continue to emphasize its protective and energizing properties. Many people believe that rubies can enhance courage, confidence, and vitality.

In addition to its protective and energizing properties, the ruby is also associated with love and passion. It is often given as a gift to express deep affection and commitment. The ruby's deep red color is a powerful symbol of love and desire, making it a popular choice for engagement rings and other romantic jewelry.
Care and Cleaning
Due to its high hardness of 9 on the Mohs scale, the ruby is a durable gemstone that can withstand everyday wear. However, it is still important to take proper care of a ruby to maintain its beauty and longevity. Rubies can have inclusions and may exhibit cleavage, which means they can be prone to chipping if not handled carefully.
To clean a ruby, it is best to use a mild soap and warm water solution. Gently scrub the stone with a soft-bristled brush to remove any dirt or debris. Avoid using harsh chemicals or abrasive materials, as these can damage the stone's surface. After cleaning, rinse the ruby thoroughly with warm water and dry it with a soft, lint-free cloth.
When storing a ruby, it is important to keep it in a cool, dry place away from direct sunlight. Exposure to heat and sunlight can cause the stone to fade or become brittle over time. It is also a good idea to store rubies separately from other gemstones to prevent scratching or chipping.
For more thorough cleaning or if the ruby has been exposed to harsh conditions, it is best to consult a professional jeweler. They can provide a more detailed cleaning and inspection to ensure the ruby remains in excellent condition.
In terms of wearing a ruby, it is generally safe to wear it on a daily basis. However, it is a good idea to avoid wearing it during activities that may expose it to impact or abrasion. This includes sports, heavy manual labor, and other activities that may put the stone at risk of damage.
