About lightbox finest™

To create a Lightbox Finest™ stone, we start with an already great stone -- our classic Lightbox lab-grown diamond.

Our new Lightbox Finest™ technology then fuses our leading patented CVD growth method with a secondary refinement. Unique to Lightbox in its blend of technologies, each stone is once more subjected to extreme heat and pressure in our lab until it emerges VVS clarity, and Colorless D,E,F - the highest color grades a stone can be.

This same integrated process applied to our color stones refines the saturation and consistency of our sparkling signature pink and blue hues.

Each stone is then cut for exceptional brilliance, to the highest industry cut standard of ‘Excellent’. Your Lightbox Finest™ solitaire is then meticulously hand-set into its 18k gold setting.
