Comment: Blissfully shaped sapphire in serious size and perfect cornflower blue. Not many stones of such quality, size and elegance are found in Mogok in any given year. The visible water lily, which (like a fine supplement) floats in one corner, is proof of the stones unique natural history and individual character but does not at all disturb its appearance. A crown specimen to any collection of fine untreated sapphire and a kingly stone for a men's ring. See magnified image.
