0.62-Carat Teal Blue Montana Sapphire


A beautiful teal blue unheated Montana sapphire faceted in my custom Helena brilliant oval design, 0.62 carats.

Out of stock


This beautiful unheated Montana sapphire is a gorgeous teal blue-green color, one of my favorite colors found in the Montana gems. The sapphire has excellent clarity, with just one tiny crystal inclusion, only visible with a 10x loupe.  In the hand, this is 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 0.62 carats and measures 5.4 x 4.6 x 3.3 mm.  It would make a superb center stone for an engagement ring.
