Sapphire refers to the color “blue.” Sapphires are one form of the mineral corundum, and although they occur in several colors, the name sapphire usually refers to the blue stone. The stone is most valuable when the color is cornflower blue. Sapphires, along with rubies, are the second hardest stones on the Mohs scale after diamonds.
