This beautiful heated Montana sapphire is a gorgeous teal blue, one of the finest shades of blue found in 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. This sapphire appears to be flawless. I don’t see any inclusions, even with a 10x loupe.
This sapphire is faceted in my “Stella” custom square cushion design that is optimized for sapphire; the result is a glittering beauty of a gemstone. The gem weighs 0.66 carats and measures 4.9 x 3.3 mm; the perfect size for an engagement ring.
