From ancient Indian traditions to the royal crowns of Europe, ruby has long been seen as a symbol of power, passion, and divine favor. Understanding its properties and history allows us to appreciate why it remains one of the most prized gemstones in the world.
Historical Significance and Cultural Symbolism
Ruby has held a revered place in human history for thousands of years. In ancient India, ruby was known as the “king of precious stones,” valued for its rarity, hardness, and beauty. Indian jewelers and rulers believed that ruby possessed mystical powers, enhancing vitality and providing protection in battle. Burmese warriors, too, carried rubies into combat, believing they granted invincibility and courage.
In medieval Europe, ruby was associated with the heart and life force. It was often believed that the stone could predict misfortune or danger, and some cultures claimed that it could cure inflammatory diseases and soothe anger. These beliefs contributed to ruby’s popularity among royalty and nobility, who used it in their jewelry and regalia as a symbol of power and divine favor.
The ruby’s symbolic meanings have evolved over time but remain rooted in themes of love, passion, and protection. In modern times, it is seen as a representation of deep affection and emotional strength, making it a popular choice for engagement rings and sentimental gifts. Its fiery red color is also closely tied to the summer season, which is why it has been chosen as the birthstone for July.
In addition to ruby, two other gemstones—onyx and turquoise—have historically been associated with July. These stones offer different energies and meanings, providing alternative choices for those born in this month. However, ruby remains the most widely recognized and celebrated July birthstone.
Geological Formation and Sources
Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). Its deep red color comes from trace amounts of the element chromium. The more chromium present in the crystal structure, the more intense the red coloration becomes. This coloration gives ruby its characteristic fiery hue and sets it apart from other corundum varieties, which are classified as sapphires in all colors except red.
Ruby is one of the hardest naturally occurring minerals, ranking 9 on the Mohs Hardness Scale. This high level of durability makes it well-suited for everyday wear and allows it to retain its brilliance over time. Its toughness also means that it can be cut into various shapes and styles without significant risk of damage.
The finest rubies are often found in Myanmar (formerly Burma), where the most prized "pigeon’s blood" color is found. This term refers to a deep red with a slight purplish secondary hue, a color considered the most valuable in the trade. Other notable ruby-producing regions include Thailand, Sri Lanka, Afghanistan, and Tanzania. Each location produces rubies with slightly different characteristics, such as color intensity, clarity, and inclusions.
The process of forming a ruby is a complex and lengthy one. It begins deep within the Earth’s crust, where high pressure and heat cause the crystallization of aluminum oxide. Trace amounts of chromium then enter the crystal lattice during this process, giving the stone its red color. Over millions of years, geological activity can bring these gems closer to the surface, where they can be mined and cut.
The rarity of ruby, combined with its beauty and durability, makes it one of the most sought-after gemstones in the world. Its value is also influenced by factors such as color, clarity, cut, and carat weight. The most valuable rubies are those with a rich red color, few inclusions, and excellent cut and symmetry.
Gemological Properties
The ruby is a remarkable gemstone in terms of its physical and optical properties. Its deep red color is due to the presence of chromium, which replaces some of the aluminum in the corundum crystal structure. This substitution alters the way light is absorbed and reflected, resulting in the characteristic red hue. The more chromium present, the deeper and more vibrant the red color becomes.
In terms of clarity, rubies often contain inclusions—small internal features that are natural to the gemstone. These inclusions can affect the stone’s appearance and value. Some inclusions are considered desirable by collectors, as they can indicate the ruby’s origin and authenticity. However, inclusions that obstruct the stone’s transparency or create visible flaws are generally undesirable.
The cut of a ruby plays a significant role in its overall appearance and brilliance. Because of its hardness, ruby can be cut into a variety of shapes, including round, oval, cushion, and princess cuts. The most popular cut for ruby is the emerald cut, which enhances the stone’s color and clarity. A well-cut ruby will display excellent light performance, with a balance between brilliance and color saturation.
Ruby’s refractive index is approximately 1.76–1.78, which means it bends light at a moderate rate. This contributes to its overall brilliance and sparkle. However, ruby does not exhibit the same level of fire (dispersion of light into spectral colors) as diamond or zircon, which have higher refractive indices and more pronounced dispersion.
In terms of durability, ruby is extremely tough and resistant to scratches and wear. It can withstand daily use in jewelry without significant damage, making it an excellent choice for rings, necklaces, and bracelets. However, it is important to avoid exposing ruby to extreme heat or sudden temperature changes, as this can cause it to crack or fracture.
The value of a ruby is determined by several factors, including color, clarity, cut, and carat weight. The most valuable rubies are those with a rich red color, minimal inclusions, and excellent cut and symmetry. Larger rubies are also more valuable, as large, high-quality stones are rare.
Symbolism and Metaphysical Beliefs
Ruby has long been associated with powerful symbolism and metaphysical properties. In many cultures, it has been seen as a stone of vitality, courage, and protection. Ancient civilizations believed that ruby could enhance physical strength and ward off negative energy. It was also thought to bring good fortune and success to those who wore it.
In modern times, ruby is often associated with love and passion. It is considered a stone of deep emotional connection and is frequently used in engagement rings and romantic gifts. Its red color is symbolic of the heart and is believed to stimulate feelings of love and devotion.
Ruby is also linked to the heart chakra, the energy center associated with love, compassion, and emotional balance. It is believed to help open the heart chakra, allowing for greater emotional expression and deeper connections with others. Some practitioners use ruby in meditation to enhance feelings of love and inner strength.
In addition to its emotional symbolism, ruby is also considered a protective stone. It is believed to shield the wearer from harm and negative influences. Some cultures have used ruby in amulets and talismans to provide protection in battle or during travel.
Ruby is also associated with transformation and inner strength. It is said to help individuals overcome fear and build confidence. Its fiery red color is symbolic of passion and determination, making it a powerful stone for those seeking to achieve their goals.
While these beliefs are not scientifically proven, they reflect the deep cultural and historical significance of ruby. Whether used for its beauty, symbolism, or spiritual properties, ruby continues to be a cherished gemstone around the world.
Ruby as a July Birthstone
Ruby has been recognized as the official July birthstone since 1912, when the Jewelers of America officially adopted it for this month. Prior to this, both onyx and turquoise were also considered appropriate gemstones for July. However, ruby’s rich red color and historical significance made it the preferred choice.
The connection between ruby and July is rooted in the symbolism of the stone. Its deep red color is associated with the heat of summer and the warmth of love. In ancient times, people believed that the gemstone should reflect the spirit of the month, and ruby’s fiery hue made it an ideal match for July.
Ruby is also a popular choice for July birthdays because of its association with vitality, passion, and protection. Those born in July are often described as warm, passionate, and emotionally expressive, and ruby is seen as a stone that enhances these traits. It is believed to bring energy, motivation, and a sense of inner strength to those who wear it.
In addition to its symbolic meaning, ruby is also a durable and versatile gemstone, making it suitable for a wide range of jewelry styles. It can be set in rings, necklaces, earrings, and bracelets, and it pairs well with various metals and gemstones. Its hardness and brilliance make it an excellent choice for everyday wear.
While ruby is the primary July birthstone, onyx and turquoise are also recognized as secondary birthstones for this month. Onyx is associated with protection and strength, while turquoise is believed to promote healing and spiritual growth. These stones offer alternative options for those who prefer different colors or energies.
Ruby’s status as the July birthstone is a testament to its enduring appeal and cultural significance. Whether worn for its beauty, symbolism, or historical connection, it remains a cherished gemstone for those born in this month.
Care and Cleaning
Proper care is essential to maintaining the beauty and brilliance of ruby. Although it is one of the hardest gemstones, second only to diamond, it can still be damaged by certain conditions. Understanding how to care for ruby ensures that it remains in excellent condition for years to come.
Ruby is resistant to scratches and abrasions, making it suitable for daily wear. However, it is important to avoid exposing it to sudden temperature changes, as this can cause it to crack or fracture. For example, moving a ruby from a hot environment to a cold one, or vice versa, can stress the stone and lead to damage.
Cleaning ruby should be done carefully to avoid using harsh chemicals or abrasive materials. A mild soap solution and a soft brush are recommended for cleaning ruby jewelry. Simply mix a few drops of mild dish soap with warm water, gently scrub the stone with a soft-bristled brush, and rinse thoroughly with clean water.
Ultrasonic cleaners can be used for ruby, but they should be used with caution. While ruby is generally safe to clean with ultrasonic methods, there are exceptions. Rubies that have been treated with oil or other substances should not be cleaned with ultrasonic cleaners, as the vibrations can cause the treatment to be removed or damaged.
Steam cleaners are generally not recommended for ruby, as the high heat can cause the stone to crack or become discolored. If steam cleaning is necessary, it should be done with a low-temperature setting and for a short duration.
Ruby should also be stored separately from other gemstones to prevent scratching. Because of its hardness, ruby can scratch softer stones such as emeralds, topaz, and sapphires. Storing it in a soft pouch or individual compartment helps prevent damage.
Avoid exposing ruby to prolonged sunlight or artificial light, as this can cause the color to fade over time. While ruby is generally stable, some treatments or inclusions may be sensitive to light exposure. Storing ruby in a dark, cool place when not in use helps preserve its color and brilliance.
By following these care and cleaning guidelines, ruby can be enjoyed for generations to come. Its durability and beauty make it a timeless gemstone, and with proper care, it will continue to shine with its fiery red brilliance.
