This beautiful heated Montana sapphire is a gorgeous teal green, a classic color for the Montana gems. 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. 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 “Helena” brilliant oval design that I’ve created and optimized for sapphire; the result is a glittering beauty of a gemstone. The gem weighs 1.25 carats and measures 6.9 mm x 5.8 mm x 4.2 mm; the perfect size for an engagement ring.
