This lovely heated Montana sapphire is a beautiful deep purple color–an uncommon hue 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. This gem has very good clarity, giving it wonderful brilliance in the hand.
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 0.54 carats and measures 5.2 x 4.3 x 3.1 mm. It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
