Comment: This may well be the only round certified Burmese sapphire above 5 carat currently in the market. It comes in a bright sky blue which supports the high brilliancy but is obviously not the classical deep Burma blue but a more pale hue. There is one silky area in the outer edge visible to the trained eye, but other than that the stone is remarkably free of inclusions. Perfect proportions, well cut. Unique blue sapphire in rare shape and of best pedigree. Not too big for a ring even in a small size.
