History and Lore of the July Birthstones
The historical journey of the July birthstones is one of ancient reverence and modern standardization. Ruby, in particular, has been a cornerstone of gemstone lore for millennia. Its deep red hue, reminiscent of blood and fire, has made it a powerful symbol across diverse cultures. In ancient times, rubies were believed to hold protective powers. Warriors in various civilizations wore rubies into battle, convinced the stones would grant them courage and shield them from harm. The stone’s color was associated with life force and vitality, making it a potent talisman for health and strength.
Beyond the battlefield, rubies have long been linked to matters of the heart. They are classic symbols of passionate love, desire, and emotional depth. In many cultures, rubies were thought to inspire love and ensure fidelity, making them a popular choice for romantic gifts and betrothal jewelry. Their connection to the heart is so profound that they were often believed to glow with an inner fire when worn by someone who was truly in love. This symbolism has persisted through the ages, cementing ruby’s status as the ultimate gem of passion.
The historical significance of ruby is also tied to its rarity and value. For centuries, fine rubies were considered as valuable, if not more so, than diamonds. Their intense color and durability made them a preferred choice for crowns, scepters, and other symbols of power and authority in royal courts from Asia to Europe. The stone’s association with the sun and its life-giving energy further elevated its status, often linking it to divine right and imperial rule.
Onyx, while less flamboyant than ruby, carries its own deep historical weight. As a traditional birthstone for July, onyx has been valued since antiquity for its unique appearance and metaphysical properties. Its name is derived from the Greek word for "claw" or "fingernail," stemming from a myth in which Cupid cut the fingernails of the sleeping Venus with his arrow, and the clippings that fell to the ground were transformed into onyx. This origin story, while mythological, speaks to the stone’s association with the goddess of love, albeit in a more somber, protective context.
Historically, onyx was primarily used for cameos and intaglios, where its layered structure could be carved to create striking relief designs. Its protective qualities were highly regarded; it was believed to guard against negative energy and to absorb and transform it. Onyx was also associated with strength, determination, and steadfastness, making it a favored stone for those in need of emotional stability and resilience. While ruby’s lore is one of outward passion, onyx’s history is one of inward fortification and protection.
The modern list of birthstones, which solidified ruby as the primary stone for July, has its roots in the 19th century. The American National Jewelers Association (now Jewelers of America) standardized a birthstone list in 1912, which has been updated periodically. This list formally recognized ruby as the July birthstone. Onyx, along with other stones like carnelian, has been listed as an alternative or traditional birthstone in various historical and alternative lists, reflecting its long-standing cultural association with the month. The duality for July 4th, featuring both ruby and onyx, highlights the richness of these historical traditions and offers a choice between a stone of fiery passion and one of grounding strength.
Geological Formation and Global Sources
Understanding the geological origins of these gemstones reveals why they possess their distinct characteristics and where they are found in the world.
Ruby: The Corundum King Ruby is the red variety of the mineral corundum, which is crystalline aluminum oxide (Al2O3). The presence of trace elements, specifically chromium (Cr), is what gives ruby its captivating red color. The intensity of the red hue is directly related to the chromium content; higher levels of chromium result in a more vibrant, saturated red. When chromium is present in lower concentrations or when other elements like iron or titanium are involved, the corundum may exhibit other colors, and it is then classified as a sapphire.
The formation of ruby requires specific and extreme geological conditions. Corundum forms in metamorphic rocks, typically in marble, pegmatites, and certain types of skarn. The most significant ruby deposits are found in a handful of locations known for producing gems of exceptional quality. Myanmar (formerly Burma) is historically the most renowned source, particularly the Mogok region, which has produced some of the finest "pigeon's blood" rubies for centuries. These Burmese rubies are prized for their vivid, pure red hue with a subtle bluish undertone.
Other major sources include: * Thailand and Cambodia: These countries are known for producing rubies that often have a darker, brownish-red hue due to higher iron content. They are a major commercial source for high-quality rubies. * Mozambique: In recent decades, Mozambique has emerged as a significant source of high-quality rubies, often with a vibrant red color. * Afghanistan: The mines in the Panjshir Valley produce rubies that can rival the finest Burmese stones in color. * Tanzania and Sri Lanka: These countries also contribute to the global ruby market, though often with stones of slightly different characteristics.
The formation process is slow and requires immense heat and pressure, making natural ruby a relatively rare and valuable commodity. The finest rubies are often found in alluvial deposits, where they have been eroded from their host rock and transported by water, concentrating them in riverbeds and gravel plains.
Onyx: A Layered Chalcedony Onyx is a variety of banded chalcedony, which itself is a microcrystalline form of quartz (silicon dioxide, SiO2). Unlike ruby, which forms under high-pressure metamorphic conditions, onyx forms in volcanic rock cavities. It is a cryptocrystalline mineral, meaning its crystals are too small to be seen with the naked eye. The distinctive black color of onyx is typically due to the presence of iron and carbon inclusions, while the bands are formed by alternating layers of chalcedony and quartz.
Onyx deposits are more widespread than those of ruby. Significant sources include: * Brazil: A leading producer of onyx and other chalcedony varieties. * India: Known for producing high-quality onyx with well-defined banding. * United States: Onyx is found in several states, including Arizona, Nevada, and Oregon. * Other countries: Onyx is also mined in Uruguay, Australia, and parts of Africa.
The geological formation of onyx is generally less complex and more common than that of ruby, which contributes to its more accessible price point. However, fine specimens with sharp, contrasting bands and a deep, even black color are still valued.
Gemological Properties: A Scientific Comparison
The physical and chemical properties of ruby and onyx are vastly different, which directly impacts their use in jewelry, durability, and value.
Ruby: * Mineral Family: Corundum * Chemical Formula: Al2O3 (Aluminum Oxide) * Hardness: 9 on the Mohs scale. This makes ruby one of the hardest natural substances, second only to diamond. Its exceptional hardness means it is highly resistant to scratching and abrasion, making it an excellent choice for jewelry that will be worn daily, such as engagement rings and pendants. * Crystal System: Trigonal * Refractive Index: 1.762 - 1.770 * Specific Gravity: 4.00 * Luster: Vitreous (glass-like) * Transparency: Transparent to translucent. Fine rubies are transparent, allowing light to pass through and create brilliance. * Color: The most critical factor for ruby value. The ideal color is a vibrant, pure red with a slight bluish undertone. The color must be vivid and saturated. Brownish or orangey hues are less desirable. Clarity is also important; while inclusions are common in natural rubies, the goal is to have inclusions that do not significantly detract from the stone's beauty or durability. A completely flawless ruby is exceptionally rare. * Cut: Rubies are cut into a variety of shapes to maximize their color and brilliance. Common cuts include oval, cushion, round, and pear. The cut must be executed precisely to ensure the stone's color is evenly distributed and its potential for light return is optimized.
Onyx: * Mineral Family: Chalcedony (Quartz variety) * Chemical Formula: SiO2 (Silicon Dioxide) * Hardness: 6.5 - 7 on the Mohs scale. While still relatively durable, onyx is softer than ruby and more susceptible to scratches and chips. It is not recommended for rings that may experience hard knocks, such as men's signet rings, but is perfectly suitable for earrings, pendants, and bracelets. * Crystal System: Microcrystalline (Quartz is trigonal, but chalcedony is often considered amorphous) * Refractive Index: 1.53 - 1.54 * Specific Gravity: 2.65 * Luster: Vitreous to waxy * Transparency: Translucent to opaque. Black onyx is typically opaque. * Color: True black onyx is a uniform, deep black. It is important to note that much of the "black onyx" in the market is actually dyed agate, which has banded layers. Natural black onyx is rarer. The value is determined by the depth and evenness of the black color and the precision of any banding in banded varieties. * Cut: Onyx is often cut into cabochons (domed, polished surfaces) to showcase its color and banding. It is also frequently carved into cameos, intaglios, and beads due to its relative softness and workability.
