This beautiful heated Montana sapphire is a lovely blue-green color, reminding me of the color of the sea. 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 tiny inclusion visible in the macro image, but it’s not visible in the hand without a 10x loupe–its eye clean. Sapphires over three carats from Montana are very uncommon!
This sapphire is faceted in my custom “Helena” oval brilliant design that has been optimized for sapphire; the result is a glittering beauty of a gemstone. The gem weighs 3.22 carats and measures 9.5 x 7.7 x 5.9 mm. It would make an amazing center stone for a unique and one-of-a-kind engagement ring!
