History and Lore
The ruby, known for its deep red hue, has long been a symbol of power, passion, and vitality. Its association with July 10th places it among the most revered of birthstones. While ruby is the official birthstone for the entire month of July, it carries special significance for those born on the 10th. Historical records and cultural practices reveal a deep-rooted reverence for this gemstone.
Ancient Beliefs and Cultural Significance
Throughout history, ruby has been regarded as a powerful gemstone, often associated with royalty and the divine. In ancient India, ruby was known as the "king of precious stones" due to its rarity and hardness. It was believed to bring wisdom, wealth, and success in love. These beliefs were not isolated to India; in medieval Europe, ruby was similarly prized. It was thought to predict misfortune or danger, and some even believed it could heal blood disorders. Such associations highlight the ruby's role as not only a decorative gem but also a protective talisman.
In Burmese culture, warriors would wear rubies into battle, believing the stone made them invincible. This belief in ruby's protective and empowering qualities persisted through many centuries and across various cultures, underscoring its universal appeal and symbolic power.
The Journey to Becoming a Modern Birthstone
The ruby's journey as a birthstone can be traced to historical traditions that connected gemstones with the months of the year. These traditions often had biblical or mythological roots. One such tradition is based on the Aaronic Breastplate mentioned in the Book of Exodus, which lists 12 gemstones. While the exact identification of these stones is debated, ruby is one of the gemstones believed to be represented.
In modern times, the ruby has been officially recognized as the birthstone for July. This designation is supported by authoritative gemological institutions and widely accepted in both the jewelry industry and among gemstone enthusiasts. The ruby's selection as the July birthstone is a testament to its enduring beauty and symbolic significance.
Geological Formation and Sources
The ruby's allure is not only in its appearance but also in the geological processes that create it. Understanding the ruby's formation and the regions where it is found provides insight into its rarity and value.
Formation and Composition
Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). The deep red color of ruby is due to trace amounts of the element chromium. The more chromium present, the stronger and richer the red hue. This unique coloration sets ruby apart from other corundum varieties, such as sapphire, which gets its blue color from trace amounts of iron and titanium.
Ruby forms under high-pressure, high-temperature conditions in metamorphic rocks. It is often found in marble and in alluvial deposits. The presence of chromium is crucial to its color, but other elements can also influence the stone's appearance. For example, secondary shades of pink, orange, and violet can indicate the ruby's origin, as different geographical regions produce rubies with distinct color variations.
Notable Sources of Ruby
The most well-known and highly regarded ruby deposits are in Myanmar (formerly Burma), where rubies have an exceptional color and a glowing fluorescence. Burmese rubies are often referred to as "pigeon's blood" for their vivid red hue with a slight purple overtone. These rubies are considered the finest in the world and are highly sought after by collectors and jewelers.
Other notable ruby sources include Thailand, Sri Lanka, Vietnam, and Madagascar. Each of these regions produces rubies with unique characteristics, but the Burmese varieties are the most prized. The geological conditions in these areas allow for the formation of rubies with varying colors and qualities, contributing to the diversity of this gemstone in the market.
Gemological Properties
Understanding the gemological properties of ruby provides insight into its durability, appearance, and value. These properties are essential for anyone interested in purchasing or caring for ruby jewelry.
Hardness and Durability
Ruby ranks a 9 on the Mohs scale of mineral hardness, just below diamond, which is the hardest mineral at 10. This high hardness makes ruby suitable for use in a variety of jewelry pieces, including rings, necklaces, and bracelets. However, it is important to note that ruby can have cleavage, which means it can be fractured along certain planes if struck with sufficient force. Therefore, while ruby is durable, it should be handled with care, especially in settings where it is exposed to potential impact.
Color and Appearance
The most defining feature of ruby is its color, which ranges from deep red to pinkish red. The term "pigeon's blood" is used to describe the most desirable ruby color—a vivid red with a slight purple overtone. This color is primarily found in Burmese rubies and is considered the benchmark for ruby quality. The presence of inclusions, or internal characteristics, can also affect the appearance of a ruby. While some inclusions are visible to the naked eye, others are microscopic and do not detract from the stone's beauty or value.
Optical Properties
Ruby exhibits strong pleochroism, meaning it can display different colors when viewed from different angles. This effect is more pronounced in rubies with certain inclusions or color zoning. Additionally, ruby can have a glassy to vitreous luster, which enhances its brilliance when cut and polished. The refractive index of ruby ranges from 1.76 to 1.78, contributing to its ability to refract light and create a sparkling appearance.
Symbolism and Metaphysical Beliefs
Beyond its physical properties, ruby has been associated with a range of symbolic and metaphysical meanings. These beliefs have been passed down through generations and continue to influence the way people perceive and use this gemstone.
Cultural Symbolism
Ruby has long been associated with love, passion, and vitality. In many cultures, it is seen as a symbol of devotion and courage. The deep red color of ruby is often linked to the heart, making it a popular choice for love and commitment-related jewelry. In ancient India, ruby was believed to bring success in love and was often used in engagement rings and wedding jewelry.
In medieval Europe, ruby was thought to bring wisdom, wealth, and success. It was also believed to protect the wearer from harm and predict danger. These beliefs contributed to its popularity among royalty and the elite, who wore ruby as a symbol of power and protection.
Metaphysical Properties
In the realm of metaphysical beliefs, ruby is associated with the root chakra, which is responsible for grounding and stability. It is believed to enhance vitality, courage, and motivation, helping individuals to overcome obstacles and achieve their goals. Ruby is also thought to promote a sense of security and confidence, making it a powerful stone for those seeking to build self-esteem.
Modern practitioners of gemstone therapy often use ruby to stimulate the heart chakra, promoting emotional healing and balance. It is also believed to enhance physical energy and endurance, making it a popular choice for athletes and individuals seeking to boost their physical performance.
Care and Cleaning
Like all gemstones, ruby requires proper care to maintain its beauty and longevity. Understanding the best practices for cleaning and storing ruby ensures that it remains in excellent condition for years to come.
Cleaning Ruby
Ruby can be cleaned with warm, soapy water and a soft cloth or brush. A mild detergent can be used to remove dirt and grime, but harsh chemicals should be avoided as they can damage the stone or its setting. Ultrasonic cleaners are generally safe for ruby, but it is important to ensure that the stone does not have any fractures or inclusions that could be worsened by the vibrations.
Steam cleaning is another effective method for cleaning ruby, but it should be used with caution. The high heat can potentially affect the stone's fluorescence or cause thermal shock if the ruby is not properly acclimated.
Storage and Handling
To prevent scratches and damage, ruby should be stored separately from other gemstones, especially those that are softer. It is best to store ruby in a soft cloth or a padded jewelry box to protect it from impact. When handling ruby jewelry, it is important to avoid exposing it to extreme temperatures or sudden temperature changes, which can cause the stone to crack or fracture.
Ruby should also be kept away from harsh chemicals, such as household cleaners and perfumes, as these can dull its surface and affect its appearance. By following these care and cleaning guidelines, ruby can be enjoyed for generations, maintaining its brilliance and beauty.
