Ruby is the red variety of the mineral corundum when it is colored by chromium. Chromium gives ruby its red color and also causes a condition called fluorescence. Florescence causes the fiery red gemstone to glow from within. Although garnets have often been confused for rubies, even with royalty, Garnets, however, do not have the ruby’s quality of an inner glow.

The finest color is a vibrant purplish red. Rubies that range towards brown, orange, or pink are considered less valuable.
