My white gold Cartier has diamonds so it's plated and I have no other so I have no point of reference, BUT! I wanted to just say I have read of others loving the patina of the non plated white gold. Seems to be a personal preference.
Very true! Others do like that warm tone of non-rhodium plated white gold and it looks fine on them but I don't think it looks good on my complexion personally. The rhodium plating on my WG wedding set wore off due to the ring friction against each other and it drove me crazy to see the original WG color that I had to reset everything to platinum since I didn't want to bother with replating ever again. OP if you're able to try both pieces side by side see if you prefer one over another on your skintone. Just know that the non-rhodium plated one will turn even more warm grey over time.
