This beautiful heated Montana sapphire is a bright teal blue, 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 only one tiny inclusion, just barely visible with a 10x loupe. The high clarity makes it bright and scintillating in the hand.
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 1.51 carats and measures 6.7 x 4.4 mm; the perfect size for an engagement ring.
