This beautiful heated Montana sapphire is a lovely teal blue, a classic Montana sapphire color and one of my favorites. 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. The sapphire has very good clarity, making 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 0.87 carats and measures 5.6 x 3.7 mm; the perfect size for an engagement ring.
