Ruby is a variety of corundum, crystallizing in the hexagonal system and typically presenting a red to pinkish-red color due to trace chromium. Crystals commonly show a hexagonal prismatic habit with a vitreous luster and sharp terminations; transparent to translucent specimens are prized in collections. Notable localities include Myanmar, Afghanistan, Tanzania, India, and Pakistan, where both transparent crystals and faceted gemstones have distinguished the species for generations.

Collectors seek Ruby for its classic color, clean crystal faces, and the ability to exhibit a strong red hue when cut or displayed in mineral cabinets. Historically significant pockets have yielded large, well-formed crystals that demonstrate the mineral’s solid durability and striking optic character. While gem-quality material draws attention for jewelry use, fine crystal specimens with rich color and minimal inclusions remain the core appeal for mineral enthusiasts, highlighting Ruby as a cornerstone among corundums.
