A beautiful teal blue heated Montana sapphire in my custom “Helena” brilliant oval design, 1.52 carats.

In stock


This beautiful heated Montana sapphire is a gorgeous teal blue color, one of my favorite blues to be found in the Montana gems.  The color was developed by heating the gem in Montana, but no other treatments were made to the gem.  The treatment is permanent and stable and not only develops the color, but also improves the clarity.  The gem has one or two tiny inclusions only visible with a 10x loupe, making it very bright and scintillating in the hand.

This sapphire is faceted in my custom “Helena” brilliant oval design that has been optimized for sapphire; the result is a glittering beauty of a gemstone.  The gem weighs 1.52 carats and measures 7.3 x 6.0 x 4.5 mm.  Sapphires this large are very rare from Montana–it would make an amazing center stone for a unique and one-of-a-kind engagement ring!
