This beautiful heated Montana sapphire is a gorgeous deep blue color. 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 does have several inclusions that are visible in the hand with the naked eye. 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 2.31 carats and measures 8.3 x 7.0 x 5.2 mm. Sapphires this large are very rare from Montana–it would make an eye-catching center stone for a unique and one-of-a-kind engagement ring!
