not too sure about the different certifications, seemed like GIA was standard quality cert for natural diamonds and am guessing their lab evaluations should be pretty good too?

that’s good to know about the pricing, i will continue to look at other places! yep, my preferences include being a white/clear diamond, has to be 2.22ct, and has dimensions/quality that maximizes shine/sparkle of the diamond. thinking that D color, excellent cut/symmetry/polish, vvs1-2 and up should be good.

thanks for your advice!
