This sort of concerns me since I'm considering the same Anita Ko bracelet!
My current dilemma is that I only wear white gold/platinum jewelry and I just think this particular piece (and alternatively the Cartier just un clou - nail bracelet) would be better in classic gold. I just don't know if I can mix things up and be ok with that. Also, considering some Ko diamond studded earrings. Sigh.
OT - I think the JUC looks much better in WG whereas the love for me has to be in YG. so I would consider it in WG if I were you (since you prefer WG). I can't say for the Anita Ko bracelet but I think the Cartier has as much staying power as the Love.
as for the actual thread: I love moving pieces along that I just don't use anymore or dont' like. no point in keeping something that I don't want, except if it is passed down from family.
