July is the month of summer’s peak, and its birthstone is as vibrant and dynamic as the season itself. The birthstone for July is the ruby, a gemstone that has captivated humanity for centuries with its deep red hue and rich symbolism. Revered as a symbol of passion, vitality, and nobility, ruby holds a unique place in the world of gemstones. It is one of the few gemstones to be designated as both a precious and a birthstone, alongside its companion, the onyx. While onyx is also associated with July, ruby remains the primary and most celebrated gemstone of the month.
This article explores the ruby in depth, drawing from historical accounts, gemological properties, and cultural significance. We will examine its geological formation, its role in different civilizations, and the reasons behind its enduring popularity in jewelry and spiritual traditions. In doing so, we aim to provide a comprehensive understanding of this extraordinary gemstone.
History and Lore
The ruby has a storied history that spans continents and centuries. Known as the "king of precious stones," ruby has been cherished for its rarity, beauty, and supposed mystical properties. In ancient India, ruby was believed to be the king of gemstones, a belief rooted in both its hardness and its vibrant red color. In medieval Europe, ruby was associated with wisdom, wealth, and success in love. It was also thought to predict misfortune or danger, a belief echoed in several ancient texts.
One of the earliest historical accounts of ruby comes from Burmese warriors, who believed that wearing rubies in battle made them invincible. This belief underscores the gemstone’s association with courage and power. Ruby was also believed to heal blood-related disorders, a property that made it a valuable asset in ancient medicine.
The ruby’s association with July dates back to ancient times, and it has remained a steadfast symbol for the month. In some historical traditions, ruby was considered to be the stone of nobility, a gem reserved for royalty and those of high status. The deep red color of ruby was seen as a reflection of lifeblood, energy, and vitality—qualities that were highly valued in many cultures.
Geological Formation and Sources
Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). What distinguishes ruby from other corundum varieties is the presence of the element chromium, which gives it its signature red color. The intensity of the red hue depends on the amount of chromium in the stone. The finest rubies, often referred to as "pigeon’s blood" rubies, are deep red with a slight purplish tint and are considered the most valuable.
Ruby is formed deep within the Earth's crust under high pressure and temperature conditions. It typically forms in metamorphic rocks, particularly in regions where limestone and other minerals have been subjected to intense heat and pressure. The process of ruby formation can take millions of years, resulting in a gemstone that is both durable and rare.
Historically, the most famous ruby deposits have been found in Burma (now Myanmar). Burmese rubies are highly prized for their exceptional color and clarity. Other significant sources include Thailand, Sri Lanka, Afghanistan, and more recently, Mozambique. Each of these regions produces rubies with distinct characteristics, influenced by the geological conditions in which they formed.
Ruby is a relatively hard gemstone, ranking 9 on the Mohs scale of mineral hardness, second only to diamond. This hardness makes ruby suitable for use in a variety of jewelry pieces, including rings, necklaces, and bracelets. However, despite its hardness, ruby can still be susceptible to damage if exposed to hard knocks or sudden temperature changes. Careful handling and proper setting are essential to preserving the beauty of a ruby.
Gemological Properties
Ruby is one of the most valuable gemstones in the world, and its worth is determined by a combination of factors including color, clarity, cut, and carat weight. The most valuable rubies are those with a rich red color, often described as "pigeon's blood," and excellent clarity. Clarity refers to the presence of inclusions or imperfections within the stone. While some inclusions are common and can even add to a ruby's character, too many or too large can detract from its value.
The cut of a ruby also plays a crucial role in its appearance and value. A well-cut ruby will maximize the stone's brilliance and color, while a poorly cut ruby can appear dull or washed out. The most common cuts for ruby include the emerald cut, round cut, and cushion cut. Each cut is chosen based on the shape and quality of the rough stone.
Ruby is also known for its refractive index, which measures how much light bends as it passes through the stone. The refractive index of ruby ranges from 1.76 to 1.78, giving it a brilliant sparkle that is highly desirable in jewelry. Additionally, ruby has a high dispersion, meaning it can refract light into a spectrum of colors, although this effect is not as pronounced as in other gemstones like diamond.
In terms of carat weight, ruby is available in a wide range of sizes, from small melee stones to large, impressive specimens. The value of a ruby increases exponentially with carat weight, especially for high-quality stones. Larger rubies are extremely rare, making them highly sought after by collectors and connoisseurs.
Symbolism and Metaphysical Beliefs
Ruby has long been associated with powerful symbolism and metaphysical properties. Across different cultures and time periods, ruby has been regarded as a stone of passion, protection, and vitality. In ancient times, ruby was believed to bring good fortune and prosperity to the wearer, while also providing protection from harm.
In medieval Europe, ruby was considered a symbol of love and was often used in romantic jewelry. It was also believed to enhance wisdom and bring clarity to the mind. The red color of ruby was associated with the heart chakra, the center of love, compassion, and emotional balance. Wearing a ruby was thought to stimulate the heart chakra, promoting emotional healing and a deeper connection to one's inner self.
In Eastern traditions, ruby is associated with the root chakra, which is the foundation of physical and emotional stability. It was believed that ruby could help ground the wearer and increase their sense of security and confidence. This belief aligns with ruby’s historical association with power and courage.
Ruby is also believed to have protective qualities. In some cultures, it was used as a talisman to ward off evil spirits and negative energies. Warriors and leaders would often wear ruby to boost their courage and ensure success in battle. This belief in ruby’s protective powers has persisted through the centuries, with many people still using ruby as a protective stone today.
In modern metaphysical practices, ruby is considered a stone of vitality and energy. It is believed to help increase energy levels, enhance motivation, and promote a sense of passion and enthusiasm for life. Ruby is also thought to be beneficial for those who struggle with fatigue or low energy, as it is believed to stimulate the body and mind.
Care and Cleaning
Given its hardness and durability, ruby is a relatively easy gemstone to care for. However, proper maintenance is essential to preserving its beauty and longevity. Because ruby is a hard gemstone, it can be cleaned with standard jewelry cleaning methods. A soft cloth and warm, soapy water are sufficient for most cleaning needs. A gentle jewelry brush can also be used to remove dirt from the stone’s surface and surrounding metal.
It is important to avoid using harsh chemicals or ultrasonic cleaners for ruby, as these can damage the stone or the setting. Acidic solutions can etch the surface of ruby, while ultrasonic cleaners may cause damage if the stone has inclusions or is set in a delicate metal. Steam cleaners are also not recommended for ruby, as the heat can cause thermal shock and potentially crack the stone.
When storing ruby jewelry, it is best to keep it in a soft, padded container or a jewelry box with separate compartments to prevent scratches. Ruby can scratch softer gemstones like topaz or emerald, so it should be stored separately from these stones. Avoid exposing ruby to extreme temperatures or sudden temperature changes, as this can cause the stone to crack or chip.
If ruby is set in a piece of jewelry, it is important to ensure that the setting is secure and free from damage. Over time, the prongs or settings can wear down, which can put the stone at risk of falling out. Regular inspections by a qualified jeweler can help identify any potential issues and ensure that the ruby remains safely set.
Ruby is also sensitive to impact, so it should be handled with care. Avoid wearing ruby jewelry during activities that may subject it to knocks or abrasions. While ruby is a durable gemstone, it is not indestructible, and proper care is essential for maintaining its beauty and value.
