0.83 carat Montana Sapphire Royal Blue (Heated)

This gorgeous royal blue is a rare color for Montana Sapphires. The most common color for a Montana Sapphire is a blue-green, but there is no green in this one. At .83 carats and 5.5x3.7, it is a lovely size to be set as the centre stone in a ring - engagement or not.


I cut this Sapphire in a simple step-cut rectangle to emphasize this truly remarkable color.


There is an inclusion, visible in some lighting, and shown in the photos. The stone has been heated to enrich the color.


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.
