This beautiful heated Montana sapphire is a gorgeous dark blue-green, a classic color for the Montana gems 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 one very slight inclusion on the side that is just barely visible to the naked eye. The inclusion has been factored into the price, making this a great value for the size and color. The sapphire has undissolved rutile silk that softens the brilliance, giving it a hazy glow.
This sapphire is faceted in a custom trillion design optimized for sapphire; the result is a glittering beauty of a gemstone. It weighs 1.61 carats and measures 6.7 x 4.8 mm; it would make a beautiful and unusual pendant or ring.
