Sapphire is the gem variety of the mineral Corundum, one of the most priced gems in the world. Their hardness is second only to diamonds and their durability makes them suitable for jewellery use. Sapphires come in all colours with the red stones called "Ruby".
The general colours are blue, green and yellow. The colours can be found together as multi-coloured gems known as "Parti Colours Sapphire".
Sapphires found at the gems fields are commonly water worn and found among water worn rocks, iron stones, zircons and other minerals which looked like old river beds. These old river beds are called "The Wash" which miners look for and get their samples tested for any sapphires deposit. Sometimes 'the wash' can be quite deep. A six sided sapphire is called a "Dog's Tooth".
Another found here is the Star Sapphire, commonly black or bronze in colour.
Inverell, Glen Innes and the surrounding district have been known as a major source of beautiful sapphires for the world market.
