This beautiful heated Montana sapphire is a rich blue-green, a classic color for 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. There may be tiny inclusions that you can find with a 10x loupe but that can’t be seen with the naked eye.
This sapphire is faceted in my custom “Testudo” brilliant oval design that I’ve created and optimized for sapphire; the result is a glittering beauty of a gemstone. The gem weighs 3.55 carats and measures 9.9 x 7.5 x 6.2 mm. It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
