Please help me here. I'm trying to choose between two diamonds (same cut, same colour, same clarity) 1.11ct and 1.22ct. The bigger one is $1k more. I know the visual difference between 1.1 and 1.2ct is very small, but similarly the difference between 1 and 1.1 is small too. I wish to have a diamond that is visually bigger than 1ct. Would the 1.1ct be mistaken as 1ct? Is the $1k worthwhile?
