22CTW round cut full circle lab grown diamond necklace in 18K white gold

Hi, I’m very interested in this necklace and had a couple of quick questions.

Could you please send one clear close-up photo of the center front section and one of the clasp area laid flat in good lighting?

Also, do you have this same necklace style with the same spacing between the stones in a version that is not graduated, with the stones remaining the same size all the way around?

If there is certification for the necklace, would you mind sending that as well?

Thank you very much.
