This beautiful heated Montana sapphire is a gorgeous rich 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. The sapphire has excellent clarity, making it bright and scintillating in the hand. 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 version of the classic Old European cut that I have optimized for sapphire; the result is a glittering beauty of a gemstone. It weighs 0.85 carats and measures 5.5 x 3.6 mm; the perfect size for an engagement ring.
