This beautiful heated Montana sapphire is a gorgeous deep 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 rutile did not completely dissolve in this gem, leaving it with a slight softened brilliance that gives it a lovely “glow” in person.
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 2.35 carats and measures 7.0 x 5.1 mm. It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
