This beautiful heated Montana sapphire is a gorgeous rich teal blue color–blue with a touch of green. 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 gem has incredibly high clarity, making it bright and scintillating in the hand. There is one tiny crystal inclusion that is difficult to find without a 10x loupe–the gem is very clean.
This sapphire is faceted in my custom “Aurora” brilliant square cushion design that I’ve created and optimized for sapphire; the result is a glittering beauty of a gemstone. The gem weighs 2.59 carats and measures 7.3 x 5.3 mm–large for a Montana sapphire. It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
