Gemological overview

Technical and gemological information about this gemstone variety.

Gemological profile

Ruby is the red variety of the mineral corundum, valued for its rich color, durability, and long-standing historical significance. Its color ranges from pinkish red to deep red, with hue, tone, and saturation playing a key role in its visual character and overall appeal.
Chemically composed of aluminum oxide (Al₂O₃), ruby crystallizes in the trigonal crystal system and belongs to the oxide mineral group. In gem-quality material, ruby typically displays a vitreous luster with transparent to translucent clarity.
The refractive index of ruby generally ranges from approximately 1.76 to 1.77, producing a restrained brilliance that emphasizes depth of color rather than strong sparkle. Rubies are found in several regions worldwide, with notable sources including Myanmar, Mozambique, Thailand, Sri Lanka, and Madagascar, each associated with distinct visual characteristics.

Durability & suitability

With a hardness of 9 on the Mohs scale, ruby offers excellent durability suitable for everyday jewelry when properly set and worn with standard care. Its high resistance to scratching and lack of cleavage make it one of the most robust colored gemstones used in jewelry.
Ruby performs exceptionally well in rings, pendants, earrings, and bracelets, including designs intended for frequent wear. While natural inclusions are common and expected in ruby, thoughtful setting design can help protect the stone and preserve its appearance over time.
