This beautiful heated Montana sapphire is a rich blue-green color, a classic color 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 gem has one small feather that just barely visible in the hand; I have factored it into the pricing, making this sapphire a great value for the size and color.
This sapphire is faceted in my custom “Helena” oval brilliant design that has been optimized for sapphire; the result is a glittering beauty of a gemstone. The gem weighs 2.83 carats and measures 8.9 x 7.6 x 5.5 mm. Sapphires this large are very rare from Montana–it would make an amazing center stone for a unique and one-of-a-kind engagement ring!
