This lovely heated Montana sapphire is a gorgeous deep blue to blue-green color, a classic color for 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 very good clarity, with just one or two tiny inclusions only visible with a 10x loupe.
This sapphire is faceted in the classic diamond round brilliant design that has been specifically optimized for sapphire; the result is a glittering beauty of a gemstone. The gem weighs 0.97 carats and measures 5.8 x 3.8 mm. It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
