Out of stock


This beautiful unheated Montana sapphire is a gorgeous light sky blue color, reminiscent of the “big skies” of Montana.  The gem has outstanding clarity, appearing flawless with a 10x loupe.  The high clarity makes it a very bright and scintillating gemstone in the hand.

This sapphire is faceted in my custom “Topangle” trillion design; the resulting gem is bright and beautiful in the hand.  It weighs 0.63 carats and measures 5.1 x 3.4 mm.  It would make an amazing center stone for a unique and one-of-a-kind engagement ring or pendant.
