This beautiful heated Montana sapphire is a gorgeous 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 inclusions that are visible in the hand and has undissolved rutile silk that softens the brilliance, giving it a hazy glow. It looks better in person than the photo implies. 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 “Eureka” brilliant rectangle cushion design that I’ve created and optimized for sapphire. The result is a glittering beauty of a gemstone. The gem weighs 4.56 carats and measures 10.3 x 7.8 x 6.5 mm; the perfect size for an engagement ring.
