This beautiful heated Montana sapphire is a golden yellow, bringing to mind the sunny skies 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 has very small inclusions that are quite difficult to see with the naked eye from a normal viewing distance.
This sapphire is faceted in our custom “Testudo” brilliant oval design, created and optimized for sapphire. The result is a glittering beauty of a gemstone. The gem weighs 1.00 carats and measures 6.6 x 5.1 x 4.0 mm.
