A collection of eight rough Sapphire crystals displaying deep blue-gray, smoky green, and dark olive coloration.

Sapphire is the gem variety of Corundum, an aluminum oxide mineral renowned for its exceptional hardness of 9 on the Mohs scale, second only to diamond among common natural minerals. New South Wales, Australia, has a long history of sapphire production, particularly from alluvial deposits associated with ancient volcanic activity. These deposits have produced sapphires in a range of blue, green, yellow, and darker tones, making the region an important locality in Australian gem mineralogy.
