This unusual heated Montana sapphire is deep golden yellow mixed with green, giving it a unique appearance. 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. There are some minor flaws but they are mostly masked by the deep color. I have factored the deep color and flaws into the pricing, making this gem a good value for the size.
This sapphire is faceted in my custom “Aurora” brilliant square cushion design that I’ve created and optimized for sapphire. The gem weighs 2.71 carats and measures 7.5 x 5.3 mm. It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
