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.
