September Birthstone Color

Sapphires are a form of corundum, the second-hardest mineral. Commonly ranging in color from light to dark blue, they are found chiefly in placer deposits, which are formed when minerals naturally separate from other sediment due to gravity. 

A sapphire may also form in a rainbow of other colors, but red-hued corundum is known as ruby, which is July’s birthstone.
