This Montana sapphire is a beautiful bright sky blue color. 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. While the macro image shows some banding/zoning of the color, this is not easily visible in the hand; the general appearance of the gem is a uniform medium sky blue color.
This sapphire was faceted in a classic emerald cut, optimized for sapphire. The result is a sparkling gem weighing 1.30 carats and measuring 6.7 x 4.7 x 3.9 mm. This would make a lovely center stone for an engagement ring.
