This gorgeous Sapphire was sourced in Montana, and is the blue-green color that Montana Sapphires are known for.
 
I cut this Sapphire in my design "Stormlight", a modified Round Brilliant.
 
It is heated and the stone is eye-clean.
 
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.
