A ruby is a variety of corundum mineral which is primarily composed of aluminum oxide. The gemstone is typically blood-red to pink in color. Ruby derives its name from 鈥渞uber鈥� which in Latin means red. It is one of the cardinal gems, a group of gemstones that are regarded as more precious than others. The presence of the element chromium in a ruby lends the red color to the gemstone.
