One of four “precious” gemstones (the others being Diamond, Sapphire, and Emerald), Ruby is red Corundum, an aluminum oxide mineral with chromium responsible for its rich, red color.
Considered by many to be the most powerful gemstone in the universe, Ruby ranges from an orangey-red to a purplish or brownish red. The most prized color is “pigeon’s blood,” pure red with a hint of blue.
