This beautiful heated Montana sapphire is a unique combination of deep blue and green. The gem shows flashes of the two colors, creating a “particolored” 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. This sapphire is nearly flawless; there appears to be no visible inclusions, even when examined with a 10x loupe
This sapphire is faceted in a modified version of the classic diamond round brilliant design that is optimized for sapphire and cut to “hearts and arrows” precision; the result is a glittering beauty of a gemstone. The gem weighs 1.69 carats and measures 7.1 mm x 4.7 mm.
