Hey everyone, I ordered a 18k rose gold solitaire from white flash, as recommended on this forum and then I ordered a 18k diamond wedding band from blue Nile on sale. However I just received the wedding band today and comparing it to my white flash engagement ring there is a bit of a color difference in the gold. Is this normal? The white flash band actually looks more yellow gold than the blue Nile one. Should I be concerned as both are supposed to be 18k rose gold? or is this normal?
