This beautiful heated Montana sapphire is a gorgeous aqua blue, bringing to mind the tropical waters of the Caribbean Sea. This sapphire has been subject to traditional heat treatment in Montana to improve the color and clarity, but no other treatments have been applied. The treatment is permanent and stable. The sapphire is slightly included and the inclusions can be seen with the naked eye; that has been factored into the pricing making this a great value for the size.
This sapphire is faceted in my custom “Testudo” brilliant oval design that I’ve created and optimized for sapphire; the result is a glittering beauty of a gemstone. The gem weighs 3.86 carats and measures 10.1 x 7.8 x 6.4 mm. It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
