My sister recieved a diamond solitare ring and claims it to be 20 carat stone, but it is smaller than mine and mine is not even 1 carat. It is frustrating, I can’t get to her stubborn head tell convince her that she is wrong, so may be they measure their diamonds in a different way? Does anybody know?
