This beautiful heated Montana sapphire is a unique combination of two colors, orange and yellow. The colors are in zones, creating a bicolored effect. The color was developed by heating the gem in Montana, but no other treatments were made to the gem. The treatment is permanent and stable and not only develops the color, but also improves the clarity. The sapphire has excellent clarity, making it bright and scintillating in the hand, and looks even better in person than the photos imply. There may be tiny inclusions that are visible with a 10x loupe that can’t be seen with the naked eye.
This sapphire is faceted in my custom “Orion” brilliant oval design that I’ve created and optimized for sapphire; the result is a glittering beauty of a gemstone. It weighs 1.60 carats and measures 7.8 x 6.3 x 4.4 mm. It would make an amazing center stone for a beautiful engagement ring!
