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.

Who We Are?
The cut of a diamond determines its brilliance, how much its facets interact with light and sparkle. Cut does not refer to the shape of a diamond, but instead grades how perfectly the stone has been cut into it’s shape.
