VS diamonds have a better clarity grade than SI diamonds with fewer inclusions (imperfections and flaws) on the surface and internally. VS stands for ‘very slightly’ included while SI stands for ‘slightly included’, indicating that VS diamonds are of better overall quality when it comes to clarity.
