As a member of the corundum mineral family, ruby is second only to diamond in hardness, making it exceptionally durable for fine jewelry. The gem's significance extends far beyond its physical properties; it is deeply woven into cultural lore, historical narratives, and modern symbolism, representing love, power, vitality, and protection. This article explores the multifaceted nature of the ruby, from its geological origins and gemological characteristics to its storied past and enduring role as July's premier birthstone.
The journey of the ruby from a mystical talisman to a modern symbol of July is a testament to its timeless appeal. While the official birthstone list has evolved, the ruby’s status has remained steadfast in contemporary times, largely solidified by the Jewelers of America's adoption in 1912. However, historical traditions offer a richer, more complex tapestry, where alternative stones like carnelian and onyx also held significance for the month. Understanding this context is essential for appreciating the full scope of July’s symbolic language, which also includes specific colors, flowers, and natural elements that together create a unique identity for those born in this vibrant summer month. This article will delve into the ruby’s historical journey, its formation and sources, its scientific properties, its metaphysical beliefs, and practical guidance for its care and maintenance.
History and Lore
The ruby’s history is as deep and intense as its color. It has been known and cherished since ancient times, earning titles such as the "king of precious stones" in India and the "King of Gems" in the Western world. In ancient India, the ruby was revered not only for its beauty and rarity but for its perceived mystical powers. It was closely associated with the life force of blood, symbolizing power, youthful energy, and vitality. The stone was believed to possess the ability to predict misfortune or danger, and it was also credited with curing inflammatory diseases and soothing anger. Burmese warriors held a particularly strong belief in the ruby's protective powers, embedding them in their flesh or believing that the stone made them invincible in battle.
This protective and life-affirming symbolism was not confined to Asia. In various cultures, the ruby was seen as a stone of passion and love, its red hue evoking the deepest emotions. Its connection to the heart and blood made it a powerful amulet for health and courage. The lore surrounding the ruby often linked its color to the essence of life itself, making it a gemstone of profound significance beyond mere adornment.
The ruby's association with the month of July is a more modern development, though its roots are in older traditions. Prior to the standardized birthstone lists of the 20th century, various cultures and historical periods assigned different stones to July. For instance, some older traditions, such as those found in 15th-century Polish and Russian lists, considered onyx an appropriate gemstone for July. Onyx, with its black surface, represented grounding and self-control, offering a stark contrast to the passionate red of the ruby. Another alternative, carnelian, a warm, orange-red stone, was widely used in ancient Egyptian jewelry and symbolized vitality and renewal—qualities that align well with the summer month.
The official modern designation of ruby as July's primary birthstone was solidified in 1912 when the Jewelers of America adopted a standardized list. This list was created to provide a consistent guide for the jewelry trade and consumers. Prior to this, the selection of a birthstone was more fluid and often based on regional or historical preferences. The 1912 list, which also included onyx and turquoise as secondary stones for July, has been updated over time, but the ruby’s position has remained unchallenged. This official adoption helped cement the ruby’s status, ensuring its continued prominence in the market and in cultural consciousness as the quintessential gem for July birthdays.
Geological Formation and Sources
Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). Its signature red color is caused by trace amounts of the element chromium substituting for aluminum in the crystal lattice. The more chromium present, the more intense the red hue. The presence of chromium is also what differentiates ruby from its close cousin, sapphire, which is also corundum but derives its color from other trace elements like iron and titanium, resulting in a spectrum of colors excluding red.
The formation of ruby requires specific and extreme geological conditions. Corundum forms in metamorphic rocks, typically aluminum-rich, silica-poor rocks that have been subjected to high temperatures and pressures. The chromium necessary for the red color must also be present in the original rock, which is a relatively rare occurrence. This combination of required elements and conditions makes fine-quality ruby an exceptionally rare gemstone, contributing to its high value.
While rubies are found in several locations worldwide, certain regions are renowned for producing stones of exceptional quality. Historically, the most prized rubies have come from the Mogok region of Myanmar (formerly Burma). Burmese rubies are famous for their "pigeon's blood" red, a term used in the trade to describe the finest color—a deep red with a slight hint of purple. The historical significance of Burmese rubies is immense, and they continue to be highly sought after in the gem market.
Other notable sources include: * Thailand: Thai rubies often have a slightly darker, brownish-red hue compared to Burmese stones. The country has been a major trading center for rubies for centuries. * Sri Lanka: Rubies from Sri Lanka are known for their lighter, more pinkish-red tones. The island has a long history of producing a wide variety of gemstones. * Vietnam: Vietnamese rubies, particularly from the Luc Yen and Quy Chau districts, can exhibit colors similar to those from Myanmar and are gaining recognition in the market. * Tanzania and Madagascar: These African nations have become important sources for rubies in recent decades, producing stones that can vary in color but often offer good clarity and size.
The geographic distribution of ruby deposits is limited, and finding new sources of high-quality material is challenging. This scarcity, combined with the gem's enduring popularity, underpins its status as one of the most valuable colored gemstones in the world.
Gemological Properties
Understanding the gemological properties of ruby is essential for appreciating its value and ensuring its longevity in jewelry. The key characteristics are outlined in the following table, which synthesizes the data from the provided sources.
| Property | Description | Significance |
|---|---|---|
| Mineral Family | Corundum | Ruby is a variety of corundum (Al₂O₃), the same family as sapphire. |
| Chemical Formula | Al₂O₃ (with trace Cr³⁺) | The presence of chromium (Cr³⁺) is what causes the red color. |
| Hardness (Mohs Scale) | 9 | Second only to diamond, making ruby extremely durable and resistant to scratching, ideal for everyday wear in rings and bracelets. |
| Crystal System | Trigonal | Rubies often form in hexagonal or flat tabular shapes. |
| Refractive Index | 1.762 - 1.770 | This high index contributes to ruby's brilliance and sparkle. |
| Specific Gravity | 4.00 | A measure of density, typical for corundum. |
| Color | Red to reddish-brown | The most valued color is a pure, vibrant red with a slight purple hue, known as "pigeon's blood." |
| Clarity | Varies | Natural rubies often contain inclusions. Flawless rubies are exceptionally rare. |
| Cut | Various | Common cuts include brilliant, step, and mixed cuts to maximize color and light return. |
| Carat Weight | Varies | Large rubies are extremely rare, and price per carat increases exponentially with size. |
The hardness of ruby (9 on the Mohs scale) is a critical property. This makes it one of the hardest gemstones, second only to diamond, and exceptionally suitable for all types of jewelry, including engagement rings that are subject to daily wear. Its durability means it is resistant to chipping and breaking, though it can still be damaged by a sharp blow due to its cleavage properties (ruby has no cleavage but can be brittle).
Color is the most important factor in determining a ruby's value. The ideal color is a vibrant, saturated red with a slightly purplish undertone, often described in the trade as "pigeon's blood." This term is specifically associated with the finest rubies from Myanmar. Other hues, such as brownish-red or pinkish-red, are generally less valuable, though they are still classified as ruby if the red is the dominant color. Clarity is also important; while inclusions are common in natural rubies, stones with fewer visible inclusions command higher prices. The presence of certain inclusions can sometimes help identify the stone's origin.
Symbolism and Metaphysical Beliefs
The symbolism of the ruby is deeply rooted in its intense red color, which universally evokes strong emotions and powerful associations. Across cultures and eras, the ruby has been a symbol of passion, love, and vitality. Its connection to the color of blood has linked it to life force, courage, and power. In Indian tradition, it was seen as a stone of power and youthful energy, while in European lore, it was associated with the heart and romantic love.
Metaphysical beliefs, often drawn from historical and cultural traditions rather than modern science, attribute several powers to the ruby: * Protection: Historically, rubies were believed to protect their wearers from harm, illness, and negative energies. Burmese warriors wore them for invincibility in battle, and they were often set in armor or worn as talismans. * Vitality and Health: Due to its blood-like color, the ruby was thought to stimulate circulation, improve heart health, and boost overall energy levels. It was also believed to have anti-inflammatory properties. * Emotional Balance: Some traditions held that the ruby could soothe anger and negative emotions, promoting a more balanced and passionate approach to life. It was also seen as a stone that could enhance confidence and motivation. * Wealth and Success: In some cultures, the ruby is considered a stone of prosperity, believed to attract good fortune and success to its wearer.
It is important to note that these metaphysical beliefs are part of cultural and historical lore. While they add a rich layer of meaning to the stone, they are not supported by scientific evidence. However, for many, these symbolic associations are a significant part of the ruby's appeal, making it a meaningful gift for occasions like anniversaries or birthdays.
The ruby's symbolism is complemented by other July symbols. The month's alternative birthstones—carnelian and onyx—carry their own meanings. Carnelian, with its warm orange-red hue, symbolizes vitality and renewal, while onyx, often black, represents grounding and self-control. These alternatives provide a broader palette of symbolic choices for July birthdays. Furthermore, July's official birth flowers, larkspur and water lily, add to the month's symbolism: larkspur represents levity and lightness, while water lily signifies purity and enlightenment. The combination of these symbols creates a multifaceted identity for July, centered on the passionate red of the ruby but enriched by the colors, flowers, and stones of summer.
Care and Cleaning
Given its exceptional hardness and durability, ruby jewelry is relatively easy to care for, making it an excellent choice for everyday wear. However, proper maintenance is essential to preserve its beauty and brilliance over time. The following guidelines are based on ruby's gemological properties.
Cleaning Methods: * Ultrasonic Cleaners: Ruby is generally safe to clean using an ultrasonic cleaner, as its hardness and lack of cleavage make it resistant to the vibrations. However, caution is advised if the ruby is set in a delicate piece of jewelry or if it has significant surface-reaching fractures, as the vibrations could potentially damage the setting or exacerbate existing inclusions. * Steam Cleaning: Steam cleaning is also typically safe for ruby due to its high hardness and stability. The high temperature and pressure of steam can effectively remove dirt and oil from the stone's surface. * Warm, Soapy Water: The safest and most recommended method for cleaning ruby jewelry is using warm water with a mild dish soap and a soft brush (like a soft-bristled toothbrush). Gently scrub the stone and its setting to remove any buildup. Rinse thoroughly with clean water and dry with a soft, lint-free cloth. * Avoid Harsh Chemicals: Ruby is resistant to most chemicals, but it is still best to avoid exposing it to harsh substances like bleach, chlorine, or strong acids, which could damage the metal setting or, in rare cases, affect the stone's surface over time.
Storage and Handling: * Separate Storage: To prevent scratching, store ruby jewelry separately from other jewelry pieces. Diamonds and other hard gemstones can scratch ruby, and ruby can scratch softer stones. Using individual jewelry pouches or compartments in a jewelry box is ideal. * Avoid Impacts: Although ruby is very hard, it can still be chipped or damaged by a sharp blow, especially if it has large inclusions. It is advisable to remove ruby jewelry during activities that could subject it to physical impact, such as heavy manual work or sports. * Regular Inspections: Periodically inspect ruby jewelry for loose settings, worn prongs, or other damage. A professional jeweler can check the security of the stone and perform any necessary maintenance to ensure it remains safely set.
By following these simple care instructions, a ruby can remain a stunning and vibrant gemstone for generations, serving as a lasting symbol of passion and vitality.
