This beautiful Montana sapphire is a lovely blue-green color, a classic color for the Montana sapphires. The color was developed by having the sapphire heated in Montana–but that is the only treatment it has had. The heating not only deepened the color, but it also improved the clarity–the gem is bright and lively in the hand. The macro image is similar to the view through a 10x loupe, and shows some tiny inclusions that are not visible in the hand.
This sapphire has been faceted in a modified version of the classic round brilliant design, optimized for sapphire. The result is a sparkling gem weighing 0.99 carats and measuring 6.0 x 3.8 mm. This would make a lovely center stone for an engagement ring.
