This beautiful Montana sapphire is a lovely sky blue 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.  This is an extremely gemstone, making it bright and scintillating 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 0.81 carats and measuring 5.5 x 3.5 mm.  This would make a lovely center stone for an engagement ring.
