    Unlike the latter, however, which is red, the sapphire is found in an infinite range of colours: sapphires may be pink, yellow, purple, green , orange, pink orange (Padparadscha), colourless... The colour of the sapphire is designated by its accompanying adjective. The word "sapphire" when used alone designates the blue variety of this gem.
