History and Lore
Ruby’s history stretches back thousands of years, with its earliest references found in ancient Indian texts. In ancient India, ruby was known as the "king of precious stones," a title that reflected its rarity, hardness (second only to diamond), and its symbolic connection to life force and energy. It was believed to possess mystical powers, including the ability to predict misfortune or danger and to cure inflammatory diseases. Burmese warriors, in particular, carried rubies into battle, believing they made them invincible.
In medieval Europe, ruby was associated with health, wisdom, and success in love. It was considered a talisman of vitality and youthful energy, often worn by royalty and nobility. Ruby’s deep red color was linked to the life-giving properties of blood and was thought to embody the essence of life itself.
Ruby has also held a special place in various cultural traditions. In some Hindu traditions, ruby is the birthstone for July and is associated with wisdom and spiritual truth. It is seen as a reminder of the purity and innocence of the soul, helping bring peace of mind to the wearer.
Ruby’s association with July dates back centuries, with its status as a birthstone evolving over time. While ruby is now the modern birthstone for July, the month originally had several historical birthstones, including carnelian, onyx, sardonyx, and sapphire. These stones were believed to offer a range of benefits, from courage and strength to protection and spiritual insight.
Geological Formation and Sources
Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). What gives ruby its signature red color is the presence of trace amounts of chromium, which replaces some of the aluminum in the crystal structure. The more chromium present, the stronger the red hue. A particularly desirable shade known as "pigeon’s blood" is a deep red with a hint of purple, often considered the finest ruby color.
Ruby forms under intense geological conditions, typically in metamorphic rocks such as marble or in igneous rocks like basalt. The presence of chromium and the right environmental conditions are crucial for the development of ruby’s vibrant color. These conditions are rare, making ruby a relatively scarce gemstone.
Historically, ruby has been found in several key locations around the world. Myanmar (formerly Burma) is one of the most famous sources of high-quality ruby, particularly the "pigeon’s blood" variety. Other significant ruby-producing regions include Thailand, Sri Lanka, Afghanistan, and parts of Africa such as Tanzania and Madagascar. Each source produces rubies with distinct characteristics, influenced by the local geology and trace elements present in the earth.
The process of extracting ruby involves careful mining techniques to avoid damaging the delicate crystals. Once extracted, rubies are often heat-treated to enhance their color and clarity. This treatment is widely accepted in the gem trade and is used to bring out the best in the stone’s natural beauty.
Gemological Properties
Ruby is a gemstone of exceptional hardness, ranking a 9 on the Mohs scale of mineral hardness, second only to diamond. This hardness makes ruby highly durable and suitable for everyday wear in jewelry. Its refractive index ranges from 1.76 to 1.78, giving it a brilliant luster that is further enhanced by its deep red color.
The most valuable rubies are those with a vivid red color, often described as "pigeon’s blood." This color is caused by the presence of chromium and the right balance of other elements. Rubies with a more orange or purplish hue are also highly prized, depending on their overall appearance and quality.
Clarity is another important factor in evaluating ruby. High-quality rubies are typically free from visible inclusions, although some inclusions are natural and can add to the stone's character. These inclusions are often referred to as "silk" and can create a star-like effect when the ruby is cut en cabochon.
Ruby is a uniaxial gemstone, meaning it has one optic axis. This property affects how light is refracted through the stone, contributing to its brilliance and fire. The best ruby cuts are designed to maximize these optical properties, ensuring the stone’s beauty is fully displayed.
Ruby is also known for its pleochroism, the ability to display different colors when viewed from different angles. This effect is most noticeable in rubies with a strong purplish or orange undertone. Skilled gem cutters take this into account when designing ruby jewelry, ensuring the stone's most attractive color is emphasized.
Symbolism and Metaphysical Beliefs
Throughout history, ruby has been associated with a wide range of symbolic meanings and metaphysical properties. In ancient times, ruby was believed to possess protective powers, shielding the wearer from harm and danger. It was also seen as a stone of vitality and youthful energy, often worn by warriors and nobility.
In many cultures, ruby is associated with passion and love. Its deep red color is symbolic of the heart and is often used in romantic jewelry. Ruby is considered a stone of courage and strength, helping the wearer to face challenges with confidence and resilience. It is also believed to promote self-awareness and a sense of empowerment, encouraging the wearer to take control of their life.
Ruby is associated with the root chakra, the energy center located at the base of the spine. This chakra is linked to grounding, stability, and a sense of security. Wearing ruby is believed to stimulate the root chakra, promoting a feeling of being grounded and connected to the earth. This can help reduce stress and anxiety, fostering a sense of calm and balance.
In metaphysical practices, ruby is also used to enhance one's personal power and assertiveness. It is believed to help the wearer overcome obstacles and achieve their goals with determination and focus. Ruby is also associated with creativity and inspiration, making it a popular stone for artists and writers.
Modern crystal healers also use ruby for its energizing properties. It is believed to help clear the body of negative energy and promote a sense of vitality and enthusiasm. Ruby is often recommended for those who feel drained or lacking motivation, as it is said to restore energy and encourage a positive outlook.
Care and Cleaning
Due to its high hardness and durability, ruby is a relatively easy gemstone to care for. However, proper maintenance is essential to preserve its beauty and longevity. Ruby should be cleaned regularly to remove dirt and oils that can dull its appearance.
The best way to clean ruby is with warm, soapy water and a soft cloth or brush. Gently scrub the stone to remove any surface dirt, then rinse it with lukewarm water and dry it with a soft cloth. Avoid using harsh chemicals or abrasive cleaners, as these can damage the stone or its setting.
Ruby can also be cleaned using ultrasonic cleaners, which use high-frequency sound waves to remove dirt and debris. This method is generally safe for ruby, but it is always advisable to consult a professional jeweler before using an ultrasonic cleaner, especially if the stone has any inclusions or is mounted in a delicate setting.
It is also important to store ruby jewelry properly to prevent damage. Store ruby in a soft pouch or a jewelry box lined with a soft material to prevent scratches and abrasions. Avoid storing ruby with other gemstones, especially those with a lower hardness, as this can lead to scratches.
When handling ruby jewelry, it is best to remove it before engaging in activities that could cause damage, such as sports, gardening, or cleaning. This helps protect both the stone and its setting from potential harm.
