This stunning Montana sapphire is a unique combination of green and yellow. The gem shows flashes of the two colors, creating a “particolored” 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 excellent clarity, making it bright and scintillating in the hand. There may be tiny inclusions that are visible only with a 10x loupe.
This sapphire is faceted in our custom “Aurora” brilliant square cushion design, created and optimized for sapphire; the resulting gemstone is bright and scintillating in the hand. The gem weighs 0.61 carats and measures 4.5 x 4.5 mm. It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
