Rubies are precious gemstones known for their vibrant red color and exceptional hardness. They are classified based on their quality, color, and origin. Here are some common types of rubies:
1. Burmese Ruby
Burmese rubies are highly prized for their deep red color, often described as “pigeon’s blood” red. They are known for their exceptional clarity, brilliance, and strong fluorescence. Burmese rubies are considered some of the finest and most sought-after rubies in the world.
2. Thai Ruby
Thai rubies, also known as Siamese rubies, are mined in Thailand. They exhibit a wide range of red hues, from light pinkish-red to deep red. Thai rubies are generally less expensive than Burmese rubies but still possess good color and clarity.
3. African Ruby
African rubies are sourced from various countries in Africa, including Mozambique, Tanzania, and Madagascar. They display a range of red shades, from vibrant red to purplish-red. African rubies are known for their good color saturation and transparency.
4. Star Ruby
Star rubies exhibit a unique optical phenomenon known as asterism. When light is reflected from needle-like inclusions within the stone, it forms a star-shaped pattern on the surface of the gem. The most common star rubies display a six-rayed star, known as a “star of David” pattern.
5. Synthetic Ruby
Synthetic rubies are laboratory-grown gemstones that possess the same chemical composition and physical properties as natural rubies. They are created through various processes, including the Verneuil method and the Flux method. Synthetic rubies can be produced in a wide range of colors and are often more affordable than natural rubies.
6. Heat-Treated Ruby
Heat treatment is a common practice in the gemstone industry to enhance the color and clarity of rubies. Heat-treated rubies undergo controlled heating to improve their color by removing or reducing undesirable tones and enhancing the red hue. Heat-treated rubies are widely available and more affordable compared to untreated or unheated rubies.
It’s important to note that the value and quality of a ruby depend on multiple factors, including its color, clarity, cut, carat weight, and overall appearance. Additionally, rubies can be found in different sizes, shapes, and cuts, offering a wide range of options to suit personal preferences and jewelry designs.
