This gorgeous heated Montana sapphire is a beautiful rich deep blue-green color, one of the finest hues of blue to be found in the Montana gems. The sapphire was heated in Montana to develop the color and improve the clarity; the treatment is permanent and stable. This gem has exceptional clarity, with just one tiny inclusion that is not visible without a loupe. This is an amazing gemstone in the hand, with rich flashes of blue on a glowing blue body color.
This sapphire is faceted in the classic diamond round brilliant design that has been specifically optimized for sapphire and cut to “hearts and arrows” precision; the result is a glittering beauty of a gemstone. The gem weighs 2.21 carats and measures 7.7 x 5.0 mm. It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
