What is Ruby?
Ruby is one of the most sought after gemstones in the world, renowned for its vibrant red color and exceptional brilliance. It belongs to the corundum family of minerals, which also includes sapphire. The red color of ruby is due to the presence of chromium within its crystal structure. With a hardness of 9 on the Mohs scale, ruby is second only to diamond in terms of hardness, making it an excellent choice for all types of jewelry, including rings and bracelets that receive daily wear.
Uses of Ruby
Ruby is a highly prized gemstone that has been cherished for centuries. Its primary use is in jewelry, where it is fashioned into rings, necklaces, earrings, and bracelets. Its striking red color makes it a popular choice for high-end and statement pieces. Beyond adornment, ruby is also used in metaphysical practices. It is believed to promote vitality, enhance passion, and provide protection against negative energies. Additionally, ruby is used in industrial applications, such as in lasers and watch bearings, due to its hardness and durability.
The Origin of Ruby
Ruby is found in various parts of the world, with significant deposits in Myanmar (formerly Burma), which is renowned for producing some of the finest rubies. Other notable sources include Thailand, Sri Lanka, Madagascar, and Mozambique. In Myanmar, the Mogok Valley is particularly famous for its high-quality stones. The gemstone forms in metamorphic rocks, often in areas that have undergone significant geological activity. Rubies are also found in alluvial deposits where they have been eroded from their original location.

Properties of Ruby
Ruby is not only beautiful but also possesses several intriguing properties. It has a high refractive index, which contributes to its brilliance and sparkle. The gemstone is also known for its fluorescence, which can enhance its red color under ultraviolet light. Ruby is extremely durable, making it resistant to scratches and everyday wear. Its vibrant red color and unique appearance make it a favorite among jewelers and gem enthusiasts alike.
Treatments of Ruby
To enhance its appearance and durability, ruby often undergoes various treatments. One common treatment is heat treatment, which is used to improve the stone's color and clarity. This treatment is generally accepted in the gemstone industry but should be disclosed to buyers. Another method is fracture filling, where the stone is filled with a glass-like substance to improve its appearance. It's important for buyers to be aware of these treatments, as they can affect the gemstone's value. Always purchase ruby from reputable dealers who disclose any treatments the stone has undergone.
