This beautiful heated Montana sapphire is a rich blue-green, 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. This sapphire has very slight inclusions that are just barely visible to the naked eye. The inclusions have been factored into the price, making this a great value for the size and color.
This sapphire is faceted in my custom “Helena” brilliant oval design that I’ve created and optimized for sapphire; the result is a glittering beauty of a gemstone. The gem weighs 4.10 carats and measures 10.0 mm x 8.5 mm x 6.3 mm; the perfect size for an engagement ring.
