This gorgeous unheated Montana sapphire is a rich royal blue color–representing the finest of the blues to be found in 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 is extremely clean, with only one tiny feather, not visible without a 10x loupe. This is a very bright and flashy gem in the hand!
This sapphire is faceted in my modified version of the classic diamond round brilliant cut, optimized for sapphire and cut to “hearts and arrows” precision. The gem weighs 1.24 carats and measures 6.1 x 4.2 mm. It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
