It does really depend upon your skin tone as to whether rose or yellow gold is a flattering choice. Let's say they both flatter you. The rose gold ring is my preference because its really goes well with the garnets and it makes the whole ring seem very unique and individual. Even if they have a few of them made it looks like its a one of a kind piece, which I think is an important element of individual style.
They are all pretty--good luck making your choice!
