A gorgeous sky blue unheated Montana sapphire faceted in my custom Helena brilliant oval design, 1.04 carats.

In stock


This beautiful unheated Montana sapphire is a gorgeous sky blue color, like the “Big Skies” of Montana.  The gem has excellent clarity, with just a tiny amount of natural rutile silk and one tiny inclusion, only visible with a 10x loupe.  The high clarity makes this a bright and scintillating gemstone.

This sapphire is faceted in my custom oval brilliant design I created just for Montana sapphire.  The design is called “Helena” in honor of the capital of Montana, located near the sapphire mines on the Missouri River in Montana. The gem weighs 1.04 carats and measures 6.3 x 5.3 x 4.0 mm.  It would make a superb center stone for an engagement ring.
