Ruby is a red variety of corundum, valued for its rich pinkish-red to deep red color caused by traces of chromium. It typically occurs in crystalline or massive form with a bright vitreous luster.
Composed of aluminum oxide (Al₂O₃), ruby has a hardness of 9 on the Mohs scale, making it one of the hardest natural gemstones and suitable for jewelry and decorative use. It is commonly sourced from regions such as Mozambique, Myanmar, and India.
Each piece displays natural variations in color, clarity, and internal inclusions, making every specimen unique.
