The birthstone for September and the official fifth wedding anniversary gift, sapphires are perfect for everyday wear.
Registering at 9 on the Mohs hardness scale, sapphire is a remarkably tough gemstone. Only diamonds are harder.
The stones are mined in the USA (mostly in Montana), Australia, India, Cambodia, Madagascar, and Tanzania. For sapphire gemstones Kenya also holds great potential, considering its access to the Mozambique Orogenic Belt.
