This beautiful heated Montana sapphire is a deep teal blue, a classic Montana sapphire color and one of my favorites. 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 a significant inclusion in the center that is visible in hand. I have factored this into the pricing, making it a good value for the size.
This sapphire is faceted in my custom “Helena” brilliant oval design that has been optimized for sapphire. The gem weighs 1.67 carats and measures 7.5 x 6.3 x 4.7 mm. It would make an eye-catching center stone for a one-of-a-kind engagement ring, at an affordable price.
