This gorgeous heated Montana sapphire is a wonderful rich royal blue color, a very uncommon shade of blue for the Montana gems. There is one tiny inclusion so small it is difficult to see even with a 10x loupe.  The high clarity makes this gem bright and scintillating in the hand.

This sapphire is faceted in my custom “Stella” square cushion design. The gem weighs 1.54 carats and measures 6.4 x 4.4 mm.  It would make a beautiful center stone for an engagement ring.
