AnuClub3mm Eternity Moissanite Wedding Band Ring, 2.3ctw D Color Lab Diamond 18K Gold Plated Silver Ring for Women With Certificate

Can someone tell me if you have to size up... I normally wear a 6?

I did not get Certificate for the mossiante band. Why not when advertised. Also came with no box.

I bought a 5ct Solitaire ring also here in ANU Club just wondering if this ring will be a great pair w/ it & is it still comfortable & not bulky?

I have very small fingers. I need a 4.25 size ring in this style. Is that possible to order?
