This Montana sapphire is a beautiful sky blue color–one of my favorite colors found in these 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.  It is exceptionally clean!  While the macro photo shows a tiny inclusion, this is not visible face up in the hand without a 10x loupe.

This sapphire has been cut in the classic diamond round brilliant design, optimized for sapphire.  The result is a sparkling gem weighing 1.40 carats and measuring 6.7 x 4.3 mm.  This would make a lovely center stone for an engagement ring.
