This pretty little unheated Montana sapphire is a classic color for Montana sapphires–a medium-light blue-green with a touch of gray tone.  The gray tone comes from a very light amount of natural rutile “silk” present in the gemstone, just barely visible in the macro image.  The macro image is like the view through a 10x loupe, and also shows one feather inclusion and a cluster of tiny black spinel crystals, or possibly they are larger rutile crystals.  In the hand these tiny crystals and the feather are impossible to see unless you use a loupe, so its an eye clean gemstone, and quite bright and lively.  Regardless, I’ve factored the inclusions into the price, making this a great value of a gemstone–and a very unique and beautiful one to study for those who love natural gems.

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 0.98 carats and measures 5.8 x 3.8 mm.
