The best-graded cubic zirconia is the diamond CZ or the 6A cubic zirconia. It features the very best elements in terms of the cut of the stone/ crystal, the clarity, and the color of the stone.

And its qualities are unmatched by those of any other CZ gemstone. This form of CZ is also called the 6A cubic zirconia white diamond.

It boasts a perfect structure, 100% inclusions-free, completely transparent, and has the brightest fire and spark. And like all other stones, the cut, shape, and size of the 6A CZ influence how light is refracted off its surface, which affects the stone’s brilliance.
