This beautiful heated Montana sapphire is a unique combination of three colors: yellow, blue, and green. The gem shows flashes of the three 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 appears to be nearly flawless. There are 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 1.48 carats and measures 6.8 x 4.5 mm; the perfect size for an engagement ring.
