Sapphires, like rubies, are a member of the corundum family and structurally almost identical. The difference between the two stones is the presence of chromium in rubies, which is what gives them their scarlet pigment. For this reason, the only colour a sapphire certainly cannot be is red. Together with rubies, sapphires are one of the hardest gemstones excluding diamonds. Iron and titanium are the principle chromophores that provide sapphires with their blue colour. Although, sapphires are usually desired for their famous blue tone, they are available in a diverse range of other colours, from pink to yellow to green. They have even been found in several shades at once, although such cases are rare. One coveted shade of sunset pink is known as the Padparadscha sapphire.
