Our lab-grown diamond quality

Our leading technology means our lab-grown diamonds are among the highest quality you can find. All Lightbox lab-grown diamonds over 0.20 carats are inscribed within the stone with our mark of quality. This laser inscription is invisible to the naked eye, but signifies that each Lightbox stone has met the internationally recognized standards of the '4 C's' as described below.
