This beautiful heated Montana sapphire is a gorgeous sky blue color, a classic color for the Montana gems. This sapphire has been subject to traditional heat treatment in Montana to improve the color and clarity, but no other treatments have been applied. The treatment is permanent and stable. This sapphire has outstanding clarity, with just a few tiny inclusions only visible with a 10x loupe.  The high clarity makes it very bright and scintillating in the hand.

This sapphire is faceted in my custom “Testudo” brilliant oval design that I’ve created and optimized for sapphire; the result is a glittering beauty of a gemstone.  The gem weighs 1.95 carats and measures 8.1 x 6.0 x 5.0 mm.  It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
