How big will a 1 carat black diamond be?

I want to get these 1 carat black diamond earring studs. I know that black diamonds are heavier then regular diamonds so a 1 carat black diamond will be smaller then a 1 carat regular diamond, but what can I compare it to? Will it be the size of a 1/2 carat regular diamond? Smaller? Larger?
Thanks!

Black diamonds are actually lighter; they have a higher coal content, which is less dense than true diamonds. But its not really noticeable.
