This lovely unheated Montana sapphire is a beautiful rich blue-green color–green tinted with blue. The color can shift with the lighting, looking more blue or more green depending on the color of the lighting. The sapphire is very clean with just a few tiny inclusions visible in the macro image, but not visible in the hand without a 10x loupe. It has a light amount of very fine natural rutile silk, softening the brilliance just a tiny bit, but it is much less noticeable than the photo makes it appear. In the hand its a gorgeous and scintillating gemstone.
This sapphire is faceted in my custom “Helena” oval brilliant design that I’ve designed and optimized for sapphire; the result is a glittering beauty of a gemstone. The gem weighs 1.70 carats and measures 7.3 x 6.1 x 4.9 mm. It would make an beautiful center stone for a unique and one-of-a-kind engagement ring.
