Ruby, a variety of corundum classified as a precious stone, is one of the world's most valuable gemstones. With its hardness and durability, ruby is an excellent choice for all types of jewelry. The color of a ruby is due to a trace of chromium in the stone; the amount of this substance determines the depth of color. Through the ages, ruby has been considered to be a gem of nobility, credited with engendering sensuality and vitality.
