This is a midnight blue Sapphire from the Queensland Gemfields of Australia. It's a naturally dark stone with flashes of beautiful royal blue; a remarkable contrast.
I cut this stone in a modified design called “Old Mine, All Mine” written by Arya Akhavan.
There is an inclusion in one corner, visible when the gem is upside down, but difficult to spot face up.
Sapphire has been popular throughout history, and that trend doesn't seem to be changing. Sapphire is a mineral called corundum, and it doesn't only come in the well-known royal blue. Corundum comes in an array of colours and shades, including white. The popular Ruby also belongs to this family as a red corundum. Sapphires and Rubies have a hardness of 9, making it the hardest coloured stone, and is well suited for daily wear.
