This beautiful heated Montana sapphire is a gorgeous deep blue-green, a classic color for 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. This sapphire has slight inclusions that are just barely visible to the naked eye, and has a slightly hazy quality due to undissolved rutile silk. The inclusions have been factored into the price, making this a great value for the size and color.
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 1.89 carats and measures 7.4 x 4.9 mm; the perfect size for an engagement ring.
