I like white metals and rose gold worn together the best. I actually love that bracelet in rose gold. However, I think rose gold is the most likely to come and go out of style, and white gold/platinum and yellow gold are the most classic and will stand the test of time. We are in a period right now where yellow gold and rose gold are in favor, but it wasn't long ago that we had a prolonged period where white metals were strongly in favor. Handbag hardware is more often going to be yellow or white metal (I see more yellow metals at the moment). So there are reasons to favor all three metals! I think they all look fine on you. I wear mostly white metals, but I like how the white diamond clovers show up more on the rg and yg. So as others have said, think about what would work for you best. I definitely get why this is a hard decision!
