This beautiful unheated Montana sapphire is a classic color for Montana sapphires–a beautiful teal blue-green hue. The gem is extremely clean, with just a few tiny lines of boehmite and a tiny feather near one edge. None of these are visible without a 10x loupe–this macro image is very similar to the view through a loupe–its a stunning eye clean gemstone, brilliant and scintillating in the hand.
This sapphire has been faceted in my own modified version of the diamond round brilliant cut, one that I’ve specifically optimized for sapphire to produce the desired “hearts and arrows” effect. The result is a scintillating gem, perfect for an engagement ring. It weighs 1.17 carats and measures 6.3 x 4.0 mm.
