This lovely heated Montana sapphire is a gorgeous teal blue, one of the finest shades of blue found in the Montana gems. This sapphire has been subject to traditional heat treatment in Montana to improve the color and clarity, but no other treatments have been applied. The treatment is permanent and stable. The sapphire has excellent clarity, making it bright and scintillating in the hand. There may be tiny inclusions that are visible with a 10x loupe that can’t be seen with the naked eye.
This sapphire is faceted in my custom “Aurora” brilliant square cushion design that I’ve created and optimized for sapphire; the resulting gemstone is bright and scintillating in the hand. The gem weighs 1.57 carats and measures 7.6 across the points, 6.2 across the flats, and has a depth of 4.5 mm. It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
