by allene » Feb 3, 2019 Thank you! Emeralds are my favorite too. Yours is beyond gorgeous!! I love it. To answer your questions, the center stone dimensions are roughly 11 x 7 x 5 mm, rounded. And, I do wear a band with it, just a plain band that is about 1.5 or 2mm wide. It sort of disappears. I've had a couple of people ask "when's the date?" because they don't see the band. I did try a thin 2mm diamond eternity next to it at first; however, my DH prefers the plain band.
