Those born in September born enjoy the sapphire as their birthstone.

Similar to a ruby, a sapphire is a variety of corundum that adorns a deep blue color. The name sapphire comes from the Latin word for "blue stone," sapphirus. The sapphire is a strong and sturdy gemstone, registering a 9 on the Mohs hardness scale (diamond is a 10). Thanks to this hardness, your sapphire birthstone is unlikely to get scratched, it also means this gem is useful for industrial that take heavy wear and tear.

You can find deep blue sapphires from Kashmir in India, which is known for producing some of the best sapphires in the world. Sapphires can also be found in Australia and Madagascar. The corundum takes on the blue coloring from trace amounts of both titanium and iron.
