This is so funny--I had the exact same issue with the clou. I tried it on practically every finger and I could not get a comfortable fit. The nail head did the same to my finger and if I went up a size to avoid that, it was too big. I just decided it wasn't the piece for me.
H rose gold is very pink so I do know what you mean about it not being an exact match with the love but that would be okay too--Lol.
As beautiful as the Kelly and CDC are stacked and I agree, they are stunning!, I'm still on the fence about the CDC ring. To stack them, I have to go up a size to 52 in the CDC ring so I don't look like I have a muffin top on my finger. Lol. The only problem with that is I would only be able to wear it stacked, as the 52 cdc is too big to wear alone. This is the only thing that has stopped me from getting the CDC ring as well. I think I'm going to get the chaine d'ancre band and wear it on a different finger. I have been trying for weeks to find a stack that works for me. Lol!!!! I can't wait to see your pieces when you get them!!!
