0.63 carat Montana Sapphire Blue-Green (Heated)

This Sapphire comes from Montana and carries the distinctive blue-green  naturally found there. It is heated to bring out the depth of color, and as you can see in the photos, is a stunning blend of those rich hues.


I cut this gemstone in a popular design called 'Ruination,' written by our good friend Arya Akhavan.


This gemstone is heat treated only and 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. Sapphire also happens to be the traditional birthstone for those born in September.
