2.49-Carat Medium Blue-Green Montana Sapphire (Heated)

A beautiful blue to blue-green heated Montana sapphire in my custom Helena brilliant oval design, 2.49 carats.

This beautiful heated Montana sapphire is a lovely medium blue-green color, the classic Montana sapphire color.  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.  This gem has a large feather near the center that slightly reduces the brilliance, although the gem is still quite beautiful and flashy in the hand.  I have priced it accordingly, making it a great value for the size.

This sapphire is faceted in my custom “Helena” oval brilliant design that I’ve designed and optimized for sapphire; the result is a glittering beauty of a gemstone.  The gem weighs 2.49 carats and measures 8.6 x 7.1 x 5.3 mm.  It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
