This beautiful heated Montana sapphire is a lovely light sky blue color, one of my favorite hues to be found in the Montana gems. The color was developed by heating the sapphire 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. This sapphire has a few tiny inclusions and a veil that is tucked off near the edge, but they are not visible without a loupe–it’s an eye-clean gemstone.
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 1.78 carats and measures 7.8 x 6.3 x 4.8 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!
