Sapphires are a gem variety of corundum, a mineral composed of aluminium oxide. Corundum is the second-hardest mineral on the Mohs scale, which is why it is an excellent choice for jewellery. And for other items that will be subject to wear and tear. Its incredible strength and durability also makes it a popular choice for a wide range of industrial applications. Watchmaking and the production of laser components are two examples.

You can find sapphires in creeks and rivers in many parts of eastern Australia. They weather out of igneous rocks that bring them to the surface of the earth, and concentrate in alluvial deposits.
