This beautiful – and very unusual – heated Montana sapphire is a unique combination of three colors: violet, teal, and yellow. The colors are in zones, creating a tricolored 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 has very slight inclusions that are just barely visible to the naked eye. The inclusions have been factored into the price, making this a great value for the size and color.
This sapphire is faceted in a custom radiant rectangle design I call “Fourth of July.” The result is a glittering beauty of a gemstone. The gem weighs 2.64 carats and measures 8.5 x 6.3 x 5.0 mm; the perfect size for an engagement ring.
