This beautiful unheated Montana sapphire is lovely pale blue color, like a blue diamond. Apart from a tiny amount of rutile silk, it has exceptional clarity. The silk is not visible except with a 10x loupe, and even then its difficult to find. In the hand this gem is bright and scintillating.
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 0.74 carats and measures 5.3 x 3.5 mm. It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
