As the birthstone for July 18th, the ruby carries a unique resonance for those born on this date, offering not only aesthetic appeal but also a rich tapestry of meaning and lore.
History and Lore
The ruby has long been regarded as one of the most valuable and powerful gemstones in the world. Its history dates back to ancient times, where it was highly prized by royalty and warriors alike. In ancient India, ruby was known as the "king of precious stones," a title that reflected its rarity, hardness (second only to diamond), and mystical properties. It was often incorporated into royal regalia and was believed to bring strength and vitality to its wearer.
Throughout history, rubies have been associated with a wide range of symbolic meanings. In many cultures, the ruby was seen as a symbol of life force, due to its deep red color reminiscent of blood. This association led to its use in jewelry and amulets meant to protect the wearer from harm and bring good fortune. In some traditions, rubies were believed to have the power to predict danger or misfortune, while others claimed they could cure inflammatory diseases and soothe anger. In Burmese culture, warriors wore rubies believing they made them invincible in battle.
The ruby's historical significance is also reflected in its use in royal courts and spiritual practices. It was often considered a stone of the heart, linked to the heart chakra and believed to enhance emotional strength and vitality. These associations have endured into modern times, with the ruby continuing to be a popular choice for jewelry and spiritual practices.
Geological Formation and Sources
The ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). What distinguishes ruby from other corundum varieties, such as sapphire, is the presence of trace amounts of the element chromium. The chromium impurities are responsible for the ruby's characteristic red color. The more chromium present in the stone, the deeper and more intense the red color becomes.
The finest rubies are those with a deep red color that has a hint of purple, known in the trade as "pigeon's blood." This term refers to the most valuable and sought-after rubies, which display a vibrant red with a slight purple undertone. The presence of this secondary hue can affect the value of the stone, with the most desirable rubies having a pure, intense red color with minimal secondary hues.
In addition to its rich red color, ruby is known for its hardness. On the Mohs scale of mineral hardness, ruby ranks at 9, making it one of the hardest gemstones. This high hardness makes it suitable for use in a variety of jewelry pieces, as it is resistant to scratches and abrasions.
Rubies are found in various locations around the world, with some of the most famous sources including Burma (now Myanmar), Sri Lanka, Thailand, and Madagascar. Burmese rubies, particularly those from the Mogok region, are highly prized for their exceptional color and clarity. These rubies have historically been considered the best in the world and have contributed to the ruby's reputation as a gemstone of the highest quality.
Gemological Properties
The ruby's gemological properties are a key factor in its desirability and value. In addition to its hardness, ruby is known for its refractive index, which is the measure of how much light is bent as it passes through the stone. Rubies have a refractive index ranging from 1.76 to 1.78, which contributes to their brilliance and fire. This high refractive index, combined with the deep red color, makes rubies particularly eye-catching and visually appealing.
Another important property of ruby is its fluorescence. Many rubies exhibit fluorescence under ultraviolet light, which enhances their color and makes them appear even more vibrant. This characteristic can add to the allure of the stone, making it appear more glowing and lively under certain lighting conditions.
The cut of a ruby can also significantly affect its appearance. Rubies are typically cut in a way that maximizes their color and brilliance. The most common cut for rubies is the oval cut, which helps to emphasize the stone's color and reduces the risk of chipping. However, other cuts such as emerald, cushion, and round cuts are also used, depending on the desired effect and the shape of the rough stone.
The size of a ruby can also influence its value. While larger rubies are generally more valuable, the color and clarity are the most important factors in determining their worth. A small ruby with a deep, vivid red color can be more valuable than a larger ruby with a less intense color.
Symbolism and Metaphysical Beliefs
The ruby has long been associated with a wide range of symbolic and metaphysical beliefs. Its deep red color has made it a symbol of love, passion, and vitality in many cultures. In ancient times, rubies were believed to have the power to protect the wearer from harm and bring good fortune. These beliefs have persisted into modern times, with the ruby continuing to be associated with strength, courage, and emotional resilience.
In many spiritual traditions, the ruby is considered a stone of the heart chakra. It is believed to enhance emotional strength, promote love, and bring vitality to the wearer. It is often used in meditation and spiritual practices to open the heart and encourage compassion and understanding. The ruby is also thought to amplify life force energy, making it a popular choice for those seeking motivation and emotional strength.
The ruby is also associated with power and protection. In some traditions, it was believed to make the wearer invincible in battle, making it a popular choice among warriors and royalty. In modern times, it is still seen as a symbol of power and confidence, making it a popular choice for those seeking to enhance their personal strength and assertiveness.
The ruby's association with duality and transformation is also reflected in its use in alternative July birthstones such as alexandrite. Alexandrite is a rare gemstone that changes color depending on the lighting conditions, making it a symbol of adaptability and inner balance. While not as common as ruby, alexandrite shares some of the same metaphysical properties and is often used by those seeking personal growth and transformation.
Care and Cleaning
Due to its high hardness and durability, ruby is a relatively easy gemstone to care for. However, it is still important to handle it with care to preserve its beauty and longevity. Rubies should be stored separately from other gemstones to prevent scratches, as even the hardest gemstones can be damaged by contact with other stones.
Cleaning a ruby can be done using mild soap and warm water. The stone can be gently scrubbed with a soft cloth or a soft-bristled brush to remove any dirt or debris. It is important to avoid using harsh chemicals or abrasive materials, as these can damage the surface of the stone. Ultrasonic cleaners are generally safe for ruby, but it is important to check with a professional jeweler to ensure that the stone is suitable for this type of cleaning.
When wearing ruby jewelry, it is important to be mindful of the activities in which it is worn. While ruby is resistant to scratches, it can still be chipped or cracked if subjected to a hard impact. It is advisable to remove ruby jewelry before engaging in activities that may expose it to damage, such as sports or heavy manual work.
