This beautiful heated Montana sapphire is one of the most desirable shades of blue. 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 is nearly flawless; there appears to be no visible inclusions, even when examined with a 10x loupe.
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 5.0 x 4.0 mm.
