This lovely heated Montana sapphire is a gorgeous bright medium blue color, one of the finest blues 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 good clarity, with just one small feather only visible with a 10x loupe.
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 0.84 carats and measures 5.6 x 3.6 mm. It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
