This beautiful heated Montana sapphire is a bright lemon yellow color–a relatively uncommon hue for 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 sapphire has some moderate inclusions, but I have factored them into the price, making it a good value.
This sapphire is faceted in my custom “Helena” brilliant oval design that has been optimized for sapphire. The gem weighs 1.00 carats and measures 6.2 x 5.3 x 4.0 mm. It would make an eye-catching center stone for a one-of-a-kind engagement ring.
