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.

Our Mission

Lightbox's cut quality

Every Lightbox lab-grown diamond has been measured as 'Very Good', and our Lightbox Finest™ stones are ‘Excellent’, offering exceptional brilliance and fire.
