This is a truly gorgeous Montana Sapphire in a deep, midnight blue. It's size is truly breathtaking along with the flashes of royal blue when the light strikes it.
 
I cut this Sapphire in a design I wrote called "Étoile", a cut I chose to help bring out its inner color.
 
There are no visible inclusions and the stone has been subjected to a standard heat treatment.
 
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.
