This beautiful heated Montana sapphire is a gorgeous combination of blue at the ends and green in the middle, creating a bicolored gem. 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 sapphire has very good clarity with just one tiny inclusion tucked off in the corner where it can be hidden under a prong when set.
This sapphire is faceted in my custom “Helena” brilliant oval design that has been optimized for sapphire. The gem weighs 1.29 carats and measures 6.8 x 5.8 x 4.4 mm. It would make an eye-catching center stone for a one-of-a-kind engagement ring.
