History and Lore
Ancient and Cultural Significance
The ruby has captivated civilizations for centuries, earning its place as the "King of Gemstones" in ancient India. Known as Ratnaraj, or "King of Gemstones," ruby was believed to possess mystical powers and was often associated with royalty and warriors. In India, ruby was considered a symbol of life force and vitality, and it was incorporated into jewelry worn by nobility to signify power and status.
Ancient Indian texts also linked ruby to the sun, associating it with solar energy and divine protection. Warriors and rulers wore ruby rings or amulets to harness its protective and invigorating qualities. The belief in ruby's power extended beyond India, with medieval European cultures attributing protective and healing properties to the gemstone. In Europe, ruby was thought to ward off evil, promote good health, and even predict danger.
In the ancient world, ruby was also connected to the life force of blood. This association gave it a powerful symbolic role in matters of the heart and courage. Some historical accounts suggest that warriors believed rubies would make them invincible in battle, while others claimed the stones could cure inflammatory diseases and soothe anger. These beliefs underscored the ruby's role as a gemstone of strength and resilience.
The ruby’s significance is also reflected in religious and literary traditions. It appears in the Bible four times, most notably in the description of the High Priest's breastplate in the Old Testament. This reference highlights the ruby's ancient importance and its perceived sacred value.
The Ruby as a Modern Birthstone
The recognition of ruby as the July birthstone can be traced back to the early 20th century. In 1912, the American National Association of Jewelers (now Jewelers of America) formalized a list of birthstones for each month of the year. Ruby was officially designated as the July birthstone, a decision rooted in long-standing traditions in countries such as India, Poland, and Russia.
This designation has endured, and today, ruby remains a powerful symbol for those born in July. Its fiery red color and deep historical roots make it a fitting emblem for the month, representing passion, vitality, and protection. The ruby’s association with love and courage also makes it a popular choice for romantic and personal jewelry.
Geological Formation and Sources
What Makes Ruby a Unique Gemstone
Ruby belongs to the corundum family, which also includes sapphires. What distinguishes ruby from sapphire is its red color, which is caused by trace amounts of chromium. The more chromium present in the crystal structure, the stronger the red coloration. The finest rubies exhibit a deep red hue with a subtle purplish overtone, a color known in the trade as "pigeon's blood."
Ruby is one of the hardest natural gemstones, ranking 9 on the Mohs scale of mineral hardness. This durability makes it ideal for use in jewelry, particularly in rings and bracelets, where it can withstand daily wear. Despite its hardness, ruby can still be susceptible to damage if struck at an angle or subjected to high heat. Therefore, it requires careful handling and proper care to maintain its brilliance over time.
Where Rubies Are Found
The finest rubies come from specific regions known for producing high-quality stones. Some of the most notable ruby sources include:
Myanmar (formerly Burma): Myanmar is renowned for producing some of the finest "pigeon's blood" rubies in the world. The Mogok region in particular is famous for its rich red stones with a deep, vibrant color. Rubies from Myanmar are highly prized in the gemstone trade and often command high prices.
Tanzania: In the 1960s, ruby deposits were discovered in Tanzania, particularly in the Tanga region. These rubies often have a slightly purplish or pinkish hue and are considered high-quality stones.
Madagascar and Sri Lanka: Both countries are significant producers of ruby. Rubies from these regions tend to have a lighter red or pinkish red color and are more abundant than those from Myanmar. They are often used in jewelry and are more affordable than Burmese rubies.
Vietnam and Afghanistan: These countries also produce ruby, though the quality and color can vary. Vietnamese rubies are often lighter in color, while Afghan rubies tend to be darker and may require treatment to enhance their color.
Rubies are formed under high-pressure and high-temperature conditions deep within the Earth's crust. They typically occur in metamorphic rocks, such as marble, where aluminum-rich minerals combine with trace elements like chromium to create the red coloration. The geological processes that form ruby are complex and rare, which contributes to its scarcity and value.
Gemological Properties
Color
The most defining characteristic of ruby is its intense red color. This coloration is due to the presence of chromium in the crystal structure. The finest rubies display a deep red with a hint of purple, known as "pigeon's blood." This color is highly sought after and is considered the most valuable in the market.
Other factors that influence ruby color include the amount of iron in the crystal and the lighting conditions under which the gemstone is viewed. Rubies with a higher concentration of chromium tend to be darker and may appear black under certain lighting. Conversely, rubies with less chromium may have a lighter, more pinkish hue.
Clarity
Ruby is a transparent gemstone, and its clarity refers to the presence of inclusions or internal flaws. Most rubies contain some inclusions, which are natural characteristics that form during the gemstone's growth. These inclusions are not necessarily a negative feature; in fact, they often help identify a ruby as natural rather than synthetic.
Clarity is an important factor in determining the value of a ruby. Stones with fewer inclusions and a clear appearance are more valuable. However, some inclusions are common and do not detract from the gemstone's beauty or durability.
Cut
The cut of a ruby plays a crucial role in its appearance and value. The most common cuts for ruby include the emerald cut, oval cut, and round brilliant cut. The emerald cut is particularly popular for showcasing the gemstone's deep red color and clarity.
The cut also affects how light interacts with the ruby. A well-cut ruby will reflect light in a way that enhances its color and brilliance. Poorly cut rubies may appear dull or lifeless, even if they have excellent color and clarity.
Carat Weight
Ruby is available in a wide range of sizes, from small gemstones used in earrings and pendants to large, high-quality stones used in rings and statement jewelry. The carat weight of a ruby is a significant factor in its value, as larger rubies are rarer and more desirable.
The price of a ruby increases exponentially with carat weight, especially for stones that exhibit the finest color and clarity. A ruby with a carat weight of one carat can be significantly more valuable than a ruby of the same quality with a carat weight of half a carat.
Hardness and Durability
Ruby ranks 9 on the Mohs scale of mineral hardness, making it one of the hardest and most durable natural gemstones. This hardness allows ruby to be used in a variety of jewelry designs, including rings and bracelets, where it can withstand daily wear.
Despite its hardness, ruby can still be susceptible to damage if struck at an angle or exposed to high heat. Therefore, it requires careful handling and proper care to maintain its brilliance and durability over time.
Symbolism and Metaphysical Beliefs
Passion and Love
Ruby has long been associated with passion and love. Its deep red color evokes the intensity of emotions, making it a popular choice for romantic jewelry. Ancient cultures believed that wearing ruby could enhance love and relationships. In Hindu traditions, it was recommended to wear a ruby near the heart to boost love and harmony in relationships.
Ruby is also a popular choice for engagement rings and anniversary jewelry. Its vibrant color and enduring brilliance symbolize the enduring fire of love. Many couples choose ruby rings to represent their deep passion and lasting commitment.
Vitality and Courage
Ruby is also a symbol of vitality and courage. Its connection to the life force of blood has made it a powerful emblem of strength and resilience. Ancient warriors wore rubies into battle, believing that the stones would protect them and enhance their courage.
Today, ruby is still associated with bravery and fearlessness. People often choose ruby jewelry to inspire themselves or their loved ones during challenging times. The gemstone's fiery energy serves as a reminder of inner strength and the ability to overcome obstacles.
Protection and Prosperity
In addition to its associations with love and courage, ruby has also been linked to protection and prosperity. Ancient cultures believed that ruby could ward off evil, promote good health, and even predict danger. Some traditions suggest that ruby can bring good fortune and success to its wearer.
Ruby is also associated with prosperity and wealth. In some cultures, it is believed that wearing ruby can attract financial success and abundance. This belief has contributed to ruby's popularity as a gemstone for business and career-related jewelry.
Care and Cleaning
Everyday Care
Due to its high hardness, ruby is suitable for daily wear in jewelry such as rings, necklaces, and bracelets. However, it still requires care to maintain its brilliance and durability. Avoid exposing ruby jewelry to high heat or sudden temperature changes, as this can cause damage to the gemstone.
When wearing ruby jewelry, be mindful of potential impacts or scratches. While ruby is hard, it can still be chipped or fractured if struck at an angle. It is also important to remove ruby jewelry before engaging in activities that may expose it to harsh chemicals or abrasive materials.
Cleaning
Ruby can be cleaned using mild soap and warm water. Gently scrub the gemstone with a soft brush to remove dirt and debris. Avoid using harsh chemicals or ultrasonic cleaners, as these can potentially damage the gemstone or any treatments it may have undergone.
For more thorough cleaning, it is advisable to take ruby jewelry to a professional jeweler or gemstone specialist. They can use appropriate methods to ensure the gemstone's brilliance is preserved without compromising its integrity.
