While corundum consists of pure alumina, sapphires always contain an admixture of other elements (iron, chromium, copper, magnesium, etc.) which give it a blue, red, yellow, pink, purple, orange or greenish color. Sapphires include all gemstones that are varieties of corundum except red, also called ruby.
