This beautiful heated Montana sapphire is a gorgeous spruce green, bringing to mind the evergreen forests of Montana. 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 flawless. I don’t see any inclusions, even with a 10x loupe.
This sapphire is faceted in my custom “Eureka” brilliant rectangle cushion design that I’ve created and optimized for sapphire. The result is a glittering beauty of a gemstone. The gem weighs 1.65 carats and measures 7.5 x 5.7 x 4.6 mm; the perfect size for an engagement ring.
