This pretty light blue-green Montana sapphire is completely natural and unheated.  It has a light amount of natural rutile “silk” that is visible in the macro image, but not visible in the hand withoug a loupe or microscope.  The silk softens the brilliance just a tiny bit, but also gives is a nice “glow” in low light.

This sapphire has been faceted in the classic diamond round brilliant cut, optimized for sapphire.  The result is a beautiful gem, perfect for an engagement ring.  It weighs 1.o9 carats and measures 6.1 x 4.1 mm.
