History and Lore
The historical narrative of ruby is rich with legend, reverence, and a connection to power and protection. While the provided sources do not detail its earliest known uses in antiquity, they firmly establish its status as a gem of immense cultural weight. Across various eras, the ruby has been more than mere ornamentation; it has been a symbol of the sun, a conduit for spiritual energy, and a marker of high status.
A significant chapter in ruby's lore is its association with nobility and the divine. The sources highlight that in some traditions, the ruby was considered a favorite stone of priests and kings, symbolizing purity and wisdom. This connection to spiritual and temporal authority underscores the gem's perceived value beyond its physical beauty. The belief in its protective powers was also profound. It was thought that a ruby could ward off evil and even influence the natural world. One specific belief, as noted in the sources, was that placing a ruby under a vessel would cause venomous snakes to die, suggesting a powerful association with the destruction of poison and evil. This attribute would have made it a potent talisman for travelers and those in positions of power.
The ruby's journey to becoming a modern birthstone is part of a broader tradition. The concept of birthstones, as discussed in the sources, evolved from ancient beliefs linking gemstones to the twelve tribes of Israel, the twelve apostles, and the twelve signs of the zodiac. This tradition was formalized over time, culminating in standardized lists. The ruby's placement in July solidified its identity as a birthstone, a role it has embraced and amplified in the commercial and cultural spheres. The sources note that the birthstone system, while sometimes viewed by critics as a marketing tool, has successfully facilitated the purchase and personalization of jewelry. For July-born individuals, the ruby offers a connection to this ancient lineage of symbolic gems, blending historical gravitas with personal significance.
Geological Formation and Sources
Rubies are a variety of the mineral corundum (aluminum oxide, Al₂O₃), whose red color is caused by trace amounts of chromium. The formation of natural rubies occurs under specific and extreme geological conditions. They are typically found in metamorphic rocks, such as marble, or in certain igneous rocks like basalt. The presence of chromium in the host rock during the formation process is essential for the development of the red color; without it, the corundum would form a sapphire of another color.
Historically, the most famed sources of fine rubies have been in Asia, particularly the Mogok region of Myanmar (Burma), known for producing rubies with a rich, "pigeon's blood" red color. However, the sources indicate a shift in the market, noting that "recent discoveries in Africa bring many attractive natural rubies into the market at affordable prices." This suggests that while traditional sources remain important, African deposits have become increasingly significant in supplying the global market with natural rubies, potentially increasing accessibility and affecting market values.
In addition to natural stones, the market is flooded with lab-grown alternatives. The sources are explicit that lab-grown rubies are "very common in jewelry stores in the United States," with a history dating back to the early 1900s. Major commercial jewelry chains often feature cases filled with lab-grown ruby items. These synthetic gems, created in controlled environments that mimic natural conditions, are chemically, physically, and optically identical to their natural counterparts. Their prevalence is driven by factors such as affordability, consistent quality, and the ability to produce larger, cleaner stones than might be found in nature. The sources also mention that lab-grown rubies often display superior clarity and color compared to natural rubies of a similar price point, a key consideration for consumers.
Gemological Properties
The ruby's desirability is rooted in its exceptional gemological properties, which make it one of the most durable and visually striking gemstones available. Understanding these properties is crucial for appreciating its value and making informed purchasing decisions.
Color: The color of a ruby is its most defining characteristic. The sources describe the range as from "orangy-red, to red, to slightly purplish-red." The most prized and valuable hues are a pure, vibrant red or a red with a slight purplish undertone. The intensity and saturation of the color are paramount; a vivid, deeply saturated red commands the highest prices in the market.
Durability and Hardness: Ruby is renowned for its outstanding durability, making it an excellent choice for all types of jewelry, including rings that are subject to daily wear. On the Mohs scale of hardness, ruby (corundum) scores a 9, making it second only to diamond (10) in terms of resistance to scratching and abrasion. This high hardness means that a ruby will rarely come into contact with an object that can abrade its surface. The sources explicitly categorize ruby as one of the "most durable birthstones," with "hardness of 9 or 10, excellent durability, and are suitable for any use in jewelry." This places it in the top tier for longevity and wearability.
Clarity: Like other gemstones, rubies can contain inclusions. The type, size, and location of these inclusions affect the stone's clarity and, consequently, its value. Natural rubies often have inclusions, and while some are accepted as evidence of their natural origin, large or detrimental inclusions can reduce transparency and brilliance. The sources note that lab-grown rubies frequently offer better clarity than natural stones of a comparable price, as the controlled growth environment minimizes the formation of inclusions.
Cut and Carat Weight: The cut of a ruby is designed to maximize its color and brilliance. Common cuts for rubies include oval, cushion, and round brilliant cuts. The carat weight, or size of the stone, significantly influences its value. Larger rubies of high quality are exceptionally rare and command premium prices per carat.

Symbolism and Metaphysical Beliefs
The symbolism of the ruby is deeply intertwined with its intense color and historical lore, often representing powerful, passionate, and protective qualities. While the sources do not provide an extensive list of metaphysical beliefs for every gemstone, they do highlight significant symbolic meanings for ruby and other stones, which provide context for its perceived powers.
The primary symbolism associated with the ruby is that of passion, love, and vitality. Its fiery red hue naturally evokes emotions of intense love and courage. Historically, as mentioned, it was linked to purity and wisdom, particularly among priests and kings, suggesting a dual symbolism of spiritual integrity and regal authority. The belief that a ruby could neutralize poison or ward off evil, as indicated by the snake legend, points to a powerful protective symbolism. This made it a popular talisman for safety and health.
In the broader context of birthstone symbolism, the sources show that gems are often ascribed with attributes intended to benefit the wearer. For example, the October birthstone, opal, is said to symbolize faithfulness and confidence, while the December birthstone, turquoise, is regarded as a love charm and a symbol of good fortune. While the specific metaphysical claims for ruby are not listed in the provided sources beyond its historical associations, its status as a "precious jewel" and a favorite of royalty inherently ties it to concepts of power, wealth, and divine favor. For individuals born in July, wearing a ruby is often seen as a way to harness these energies, fostering confidence, passion, and protection.
Care and Cleaning
Given its exceptional hardness and durability, caring for a ruby is relatively straightforward, making it a practical choice for everyday jewelry. However, proper care ensures that the gem retains its brilliance and structural integrity over a lifetime.
Durability Considerations: As a member of the "Excellent" durability category, ruby is highly resistant to scratching and chipping. Its hardness of 9 on the Mohs scale means it can withstand daily wear without significant risk of surface abrasion from common materials. However, like all gemstones, it can be damaged by a sharp, hard blow, so caution is advised during activities that could subject the jewelry to impact.
Cleaning Instructions: Cleaning ruby jewelry is simple. The safest method is to use warm water, a mild dish soap, and a soft brush (such as a toothbrush with soft bristles). Gently scrub the gemstone and its setting to remove oils, lotions, and dirt. Rinse thoroughly with clean water and dry with a soft, lint-free cloth. It is important to avoid harsh chemicals, such as bleach or chlorine, which can damage the metal setting or, in rare cases, affect certain treatments (though most rubies are not treated with heat or chemicals that would be vulnerable to household cleaners). Ultrasonic cleaners and steam cleaners are generally safe for ruby, but it is always advisable to consult with a professional jeweler before using these methods, especially if the ruby is set in a delicate or older piece of jewelry.
Storage: When not worn, ruby jewelry should be stored separately from other pieces to prevent scratching. A fabric-lined jewelry box or a soft pouch is ideal. Given its hardness, a ruby can scratch softer gemstones like opal or pearl, so keeping it isolated is important.
Considerations for Treatments and Synthetics: The care for a lab-grown ruby is identical to that of a natural ruby, as they are chemically identical. However, the sources emphasize the importance of disclosure. When purchasing a ruby, it is crucial to know whether it is natural or lab-grown, as this significantly affects value. Reputable jewelers will provide this information, as required by industry guidelines. For natural rubies that have undergone treatments (such as heat to improve color and clarity), the cleaning process is still the same, but knowing the treatment history is part of the gem's provenance.
