This beautiful unheated Montana sapphire is a gorgeous bright medium blue color, representing some of the best blue to be seen in the unheated Montana sapphires. While the macro image shows some minute rutile silk, it is not visible in person without a 10x loupe, except as tiny flashes when the gem is tilted in bright light. In the hand its a beautiful and bright gemstone.
This sapphire is faceted in my modified version of the diamond round brilliant cut, optimized for sapphire and cut to “hearts and arrows” level of precision; the result is a glittering beauty of a gemstone. The gem weighs 0.91 carats and measures 5.8 x 3.8 mm. It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
