This beautiful heated Montana sapphire is a unique combination of two colors, blue and green. The colors are in zones, creating a bicolored effect. 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. This sapphire has slight inclusions that are just barely visible to the naked eye. I have factored the inclusions into the price, making this a great value for the size and color.
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 3.71 carats and measures 10.1 x 7.7 x 6.2 mm. It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
