In stock


This gorgeous heated Montana sapphire is a rich teal blue, a classic Montana sapphire color and one of my favorites. It is extremely clean, with no inclusions visible even when examined with a loupe.  The high clarity makes it a very bright and scintillating gemstone.

This sapphire is faceted in my custom “Testudo” brilliant oval design. The gem weighs 1.17 carats and measures 6.7 x 5.1 x 4.2 mm.  It would make a beautiful center stone for an engagement ring.
