This beautiful heated Montana sapphire is a unique combination of two colors, blue and green. 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. This sapphire appears to be nearly flawless. There are no visible inclusions, even when examined with a 10x loupe.
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 2.43 carats and measures 8.6 x 6.8 x 5.2 mm. It would make an amazing center stone for a beautiful engagement ring!
