Introduction
Ruby, a precious gemstone belonging to the corundum family, is widely recognized as the birthstone for those born in July. Known for its striking red color, ruby is one of the most coveted and valuable gemstones in the world. Its fiery hue, derived from trace amounts of chromium, has made it a symbol of love, power, and energy across cultures and eras.
This article will explore ruby in detail, drawing on historical accounts, gemological data, and cultural beliefs. We will examine its geological formation, the locations where it is found, its symbolic meaning, and how it is cared for. Additionally, we will touch upon the significance of ruby in jewelry and its role as a birthstone.
History and Lore
Ruby has a long and storied history that spans continents and centuries. In ancient India, ruby was referred to as "ratnaraj," which translates to "king of precious stones," a testament to its esteemed status. Its association with life force and vitality made it a prized possession among royalty and warriors alike. In medieval Europe, ruby was believed to bring health, wisdom, and success in love, while Burmese warriors carried it into battle, believing it would grant them invincibility.
Ruby's significance also extends to the world of literature and the arts. Shakespeare, for instance, frequently referenced rubies in his works, highlighting their beauty and symbolic power. In 1998, the Nebraska Gem and Mineral Club even used a line from A Midsummer Night’s Dream—"Those be rubies, fairy favors"—as the theme for their 40th anniversary show.
In various cultures, ruby has been regarded as more than just a gemstone. It has been seen as a protective talisman, a symbol of divine power, and even a stone of spiritual transformation. In Hindu tradition, ruby was one of the gems in the magical necklace of Vishnu, one of the most revered deities in Hinduism. The Persians, too, regarded ruby as a symbol of dignity, charity, and divine power.
Ruby is also associated with important life milestones. It is traditionally given as a gift for the 15th and 40th wedding anniversaries, further cementing its role in human history and sentiment.
Geological Formation and Sources
Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). The gem's vivid red color is due to the presence of trace amounts of chromium, which replaces some of the aluminum atoms in the crystal structure. The more chromium present, the deeper the red color. The most prized rubies exhibit a rich red hue with a slight purplish tone, known in the trade as "pigeon's blood."
The formation of ruby requires specific geological conditions. It typically forms in metamorphic rocks, particularly in marble, and is also found in igneous rocks like basalt. The process involves high heat and pressure over millions of years, allowing the aluminum and oxygen atoms to bond and form the corundum crystal structure.
Rubies are found in several parts of the world, including:
- Myanmar (Burma): The most famous source of high-quality rubies, particularly the "pigeon's blood" variety.
- India: Known for producing fine rubies, especially from the Kollur mine in Golconda.
- Sri Lanka: Produces smaller but vibrant rubies.
- Madagascar: A more recent source of ruby, with increasing production.
- Vietnam, Thailand, and Afghanistan: Also contribute to the global ruby market.
Rubies are rare, especially in the finest colors and qualities. As a result, they are among the most valuable gemstones in the world. Unlike diamonds, which are found in many locations and in relatively large quantities, fine rubies are scarce, making them highly sought after by collectors and jewelers.
Gemological Properties
Understanding the gemological properties of ruby is essential for anyone interested in its beauty, value, and care. Here are some key properties of ruby:
- Color: Ruby is known for its red to orange-red to purple-red hues. The most valuable and desirable color is a deep red with a hint of purple, known as "pigeon's blood."
- Hardness: Ruby ranks 9 on the Mohs scale of mineral hardness, making it second only to diamond. This high hardness makes ruby durable and suitable for everyday wear.
- Chemical Composition: Ruby is a variety of corundum, with the chemical formula Al₂O₃. The red color is caused by the presence of chromium.
- Refractive Index: Ruby has a refractive index of 1.76–1.78, which contributes to its brilliance and fire.
- Luster: It has a vitreous (glassy) luster, which enhances its visual appeal.
- Inclusions: Rubies often contain inclusions, which are natural imperfections that can add to their uniqueness. These can include needle-like rutile inclusions, known as "silk," and other mineral crystals.
- Cut: Rubies are commonly cut into traditional shapes such as round, oval, cushion, and emerald. The cut is chosen to maximize color, brilliance, and clarity.
- Carat Weight: Rubies can be found in a wide range of sizes, from small melee stones to large, valuable gems. The price per carat increases exponentially with size, especially for high-quality rubies.
- Treatment: Many rubies are heat-treated to enhance their color and clarity. This is a common and accepted practice in the gemstone industry.
These properties make ruby not only a beautiful gemstone but also a durable one, suitable for a wide range of jewelry applications.
Symbolism and Metaphysical Beliefs
Ruby has long been associated with powerful symbolism and metaphysical beliefs. Across cultures and eras, it has been regarded as a stone of vitality, protection, and spiritual significance.
- Power and Vitality: Ruby is often associated with strength, energy, and passion. It is believed to enhance physical vitality and stimulate the life force within the body.
- Love and Passion: As a symbol of deep emotions, ruby is often used in engagement rings and love tokens. It represents enduring love, commitment, and emotional depth.

While these metaphysical beliefs are not scientifically validated, they continue to hold cultural and emotional significance for many people who wear or collect ruby.
Care and Cleaning
Due to its high hardness and durability, ruby is relatively easy to care for compared to other gemstones. However, proper care is essential to preserve its beauty and value over time.
- Cleaning: Ruby can be cleaned with warm, soapy water and a soft brush. It is also safe to use ultrasonic and steam cleaners, provided the gemstone is free of fractures or treatments that might be affected by heat or vibration.
- Avoiding Damage: Although ruby is hard, it can still chip or crack if subjected to sudden impacts. Avoid exposing it to extreme temperatures or harsh chemicals, which can damage the stone or its setting.
- Storage: Store ruby jewelry separately from other jewelry to prevent scratches. Soft fabric pouches or jewelry boxes with compartments are ideal for storage.
- Professional Inspection: Have ruby jewelry professionally inspected and cleaned periodically, especially if it is set in a delicate or intricate design.
By following these simple guidelines, ruby jewelry can remain beautiful and valuable for generations.
