History and Lore: The Enduring Reign of the King of Gems
The ruby's claim to the title "King of Gemstones" is deeply rooted in history. Its reign is not a recent development but a legacy built over millennia. In the ancient world, the ruby was more than an ornament; it was an emblem of power and a talisman of protection. Historical accounts, as referenced in the provided materials, consistently highlight its use in royal courts, where it was believed to safeguard its wearer from harm and attract fortune. This historical significance is a key factor in its selection as the primary July birthstone, a position it solidified in the modern era.
Prior to the standardization of birthstones in the 20th century, the gemstones associated with July were more varied. The provided sources indicate that before 1912, when the Jewelers of America officially adopted ruby as the July birthstone, both onyx and turquoise were considered appropriate gemstones for this month. This historical context is crucial for understanding the evolution of birthstone lists. While ruby has always been a prominent choice, its official designation as the July birthstone is a relatively modern convention, cementing its status in contemporary jewelry and culture.
Beyond its official designation, the ruby's lore is rich with symbolism. It has been consistently associated with passion, love, and vitality across different cultures. This is not merely a matter of color association; the stone's intensity is believed to mirror the intensity of human emotion and life force. In spiritual practices, the ruby is linked to the heart chakra, the energy center associated with love and compassion. It is believed to energize and open this chakra, promoting feelings of love, compassion, and vitality while helping to clear emotional blockages. This deep connection to the heart and to emotional strength makes it a powerful stone for motivation and for fostering a stronger sense of purpose in life.
The ruby's historical journey also includes its role in ancient calendars and religious texts. Some traditions, such as the Hindu calendar, also recognize other gemstones for July, like sapphire, but the ruby's prominence in Western and global gemology remains unmatched. Its historical narrative is one of unwavering prestige, a gemstone that has been coveted by emperors, warriors, and lovers alike for its perceived ability to imbue the wearer with courage and an indomitable spirit.
Geological Formation and Sources
The ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). Its iconic red color is caused by trace amounts of the element chromium (Cr) replacing a small portion of the aluminum in the crystal lattice. The presence of chromium is what distinguishes a ruby from other colored corundum varieties, most notably sapphire. The formation of ruby requires specific and extreme geological conditions. It is typically found in metamorphic rocks, such as marble, and in certain igneous rocks like basalt. The process involves the recrystallization of aluminum and oxygen-rich minerals under high temperatures and pressures, with chromium being introduced into the environment.
While the provided sources do not list specific modern mining locations, they acknowledge the gem's rarity. The formation of high-quality, transparent rubies with intense color saturation is a rare geological event, making natural rubies among the most valuable gemstones in the world. Historically, some of the most famous ruby deposits have been located in Southeast Asia, particularly in Myanmar (Burma), which is renowned for producing rubies with a rich, "pigeon's blood" red hue. Other notable sources have included areas in Thailand, Sri Lanka, and parts of Africa. The rarity of large, gem-quality crystals contributes significantly to the ruby's high market value, often surpassing that of other colored gemstones.
The mining process for rubies is typically labor-intensive, often involving artisanal methods due to the nature of the deposits. The rough crystals are then carefully cut and polished to maximize their color and clarity. The value of a ruby is determined by a combination of factors, including its color, which is the most critical attribute, followed by clarity, cut, and carat weight. The most prized rubies exhibit a vivid, medium to medium-dark red to purplish-red hue with strong saturation. Any secondary hues, such as orange or purple, can affect the value, with pure red being the most desirable.
Gemological Properties
The ruby is celebrated not only for its color but also for its exceptional physical properties, which make it both durable and brilliant. The following table summarizes the key gemological characteristics of ruby, based on its classification as a variety of corundum.
| Property | Description |
|---|---|
| Mineral Family | Corundum |
| Chemical Formula | Al₂O₃ (Aluminum Oxide) |
| Color | Red to reddish-brown; the presence of chromium (Cr) causes the red color. |
| Hardness (Mohs Scale) | 9 |
| Crystal System | Trigonal |
| Refractive Index | 1.76 - 1.77 |
| Specific Gravity | 3.95 - 4.10 |
| Luster | Vitreous (glass-like) |
| Transparency | Transparent to translucent |
Hardness and Durability: One of the most significant attributes of the ruby is its hardness. Ranking a 9 on the Mohs scale of mineral hardness, it is second only to diamond (which is a 10). This exceptional hardness makes the ruby an excellent choice for jewelry that is worn daily, such as engagement rings and pendants, as it is highly resistant to scratching and abrasion. However, like all gemstones, it can still be chipped or broken if struck with sufficient force against a hard surface.
Color: The color of a ruby is its defining feature. The ideal color is a vibrant, saturated red with a slight bluish or purplish undertone. The trace element chromium is responsible for this color, but the presence of other elements like iron can influence the hue, sometimes adding a brownish or orange tint. The most valuable rubies, often from Myanmar, are described as having a "pigeon's blood" red color, a term that signifies a pure, vivid red with a slight bluish undertone.
Clarity: Most natural rubies contain inclusions, which are internal characteristics like tiny crystals, needles, or fingerprint-like patterns. These inclusions are often accepted as evidence of the stone's natural origin. In fact, a completely flawless ruby is exceedingly rare and would command an exceptionally high price. The type and visibility of inclusions affect the stone's clarity grade and, consequently, its value. Some inclusions, like fine silk (minute rutile needles), can even enhance the stone's appearance by scattering light and improving color saturation.
Cut and Carat: Rubies are cut into various shapes to maximize their color and minimize the appearance of inclusions. Common cuts include oval, cushion, and round brilliant. The cut must be precise to ensure the stone's color is evenly distributed and its brilliance is optimized. Carat weight is a straightforward measure of size, but the price per carat for rubies increases exponentially with size, especially for stones over one carat with top-quality color and clarity.
Symbolism and Metaphysical Beliefs
The ruby's symbolism is as intense as its color. For centuries, it has been a powerful symbol of passion, love, and vitality. Its connection to the heart chakra in crystal healing traditions is profound. Practitioners believe that wearing or meditating with a ruby can energize the heart chakra, promoting feelings of love, compassion, and emotional warmth. It is said to help clear emotional blockages, allowing for deeper connections with others and fostering a sense of courage in matters of the heart.
Beyond love, the ruby is also a stone of protection and strength. Historically, it was believed to guard against physical danger and to warn its wearer of impending misfortune by changing color. This lore contributes to its reputation as a talisman for warriors and leaders. In modern metaphysical practices, the ruby is associated with leadership, motivation, and the amplification of life force energy. It is believed to stimulate the root chakra as well, grounding the wearer and providing a sense of stability and security.
The ruby's energetic properties are often described as "hot" or "fiery," mirroring its appearance. This makes it a stone for action, ambition, and overcoming lethargy. It is recommended for individuals seeking to boost their confidence, pursue their goals with vigor, and reignite their passion for life. While these metaphysical beliefs are not scientifically proven, they form a significant part of the ruby's cultural legacy and add a layer of depth to its appeal for those who are spiritually inclined.
Care and Cleaning
Due to its exceptional hardness (9 on the Mohs scale), the ruby is a relatively durable gemstone suitable for everyday wear. However, proper care is essential to maintain its brilliance and structural integrity over a lifetime. The following guidelines are recommended for cleaning and storing ruby jewelry.
Cleaning Methods: - Warm, Soapy Water: The safest and most effective method for cleaning most rubies is to use a solution of warm water and a few drops of mild dish soap. Gently scrub the stone with a soft-bristled toothbrush, paying attention to the back of the setting where dirt and oils can accumulate. Rinse thoroughly with clean water to remove all soap residue. - Ultrasonic Cleaners: Rubies without significant inclusions or fractures can generally be cleaned in an ultrasonic cleaner. However, caution is advised for stones with extensive inclusions or those that have been fracture-filled (a common treatment for rubies). The vibrations could potentially cause damage. It is always best to consult with a professional jeweler before using an ultrasonic cleaner. - Steam Cleaners: Steam cleaning is not recommended for rubies, especially those that have been treated with heat or fracture-filled, as the high temperature and pressure can cause damage.
What to Avoid: - Harsh Chemicals: Avoid exposing rubies to harsh chemicals, including bleach, chlorine, and strong acids, which can damage the stone or its setting. - Abrasive Cleaners: Do not use abrasive cleaners or brushes that could scratch the metal setting or, in rare cases, the stone's surface if it is of lower quality. - Sudden Temperature Changes: Avoid exposing ruby jewelry to extreme and sudden temperature changes, which could cause thermal shock and potentially crack the stone.
Storage: - Separate Storage: Always store ruby jewelry separately from other pieces to prevent scratching. While ruby is hard, it can scratch softer gemstones, and it can be scratched by diamonds and other corundum varieties. - Soft Pouch or Lined Box: Store each piece in a soft cloth pouch or a jewelry box with a soft, padded lining. This protects the stone from dust, scratches, and accidental impacts.
By following these simple care instructions, a ruby can retain its captivating beauty and symbolic power for generations, making it a lasting heirloom and a cherished piece of jewelry.
