This beautiful heated Montana sapphire is a unique combination of two colors, blue and green. The colors are in zones, creating a bicolored effect. 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 a classic emerald cut, optimized for sapphire and cut to high precision; the result is a glittering beauty of a gemstone. The gem weighs 0.63 carats and measures 4.9 x 4.1 x 3.2 mm; the perfect size for an engagement ring.
