Ruby

Ruby
Ruby is a captivating gemstone renowned for its vibrant red hue and exceptional durability. As a variety of the mineral corundum, rubies owe their rich color to the presence of chromium, which replaces some aluminum atoms in the crystal structure, imparting the characteristic red coloration. The term “ruby” comes from the Latin word “rubber”, meaning red, reflecting its primary color.
Variety and Category
- Mineral Family: Corundum
- Chemical Formula: Al₂O₃ (aluminum oxide)
- Crystal System: Trigonal

Rubies are second only to diamonds in hardness, just like sapphires, making them highly suitable for various types of jewelry that endure daily wear. This exceptional hardness contributes to their lasting appeal and resilience.
Color and Value
The most prized rubies exhibit a vivid, pure red to slightly purplish-red color, often referred to as “pigeon blood” red. This intense coloration, combined with high transparency and minimal inclusions, significantly enhances the gemstone’s value. Rubies with such qualities are exceedingly rare and command premium prices in the market.
Common Cuts and Applications of Ruby

Rubies are typically cut into shapes that maximize their color and brilliance, such as oval, cushion, and round cuts. Their remarkable hardness and vibrant color make them ideal for various types of jewelry, including rings, necklaces, earrings, and bracelets. Rubies are also traditionally associated with love and passion, making them popular choices for engagement rings and anniversary gifts.
Sri Lankan Uniqueness
Sri Lanka, historically known as Ceylon, has been a significant source of high-quality rubies for centuries. The country’s gem-rich regions, particularly around Ratnapura, have yielded rubies renowned for their exceptional clarity and vibrant color. Sri Lankan rubies often display a unique pinkish-red hue, distinguishing them from rubies found in other parts of the world. The combination of superior quality, ethical mining practices, and skilled craftsmanship solidifies Sri Lanka’s reputation as a premier source of exquisite rubies.
