Help me decide metal color!

My boyfriend and I went ring shopping and settled on a 3.69ct radiant lab diamond (which I am obsessed with, first picture). We are going for a solitaire, no pavè. I just can’t decide on a metal color. I wear both gold and silver, but would love opinions on what is more flattering on me. I know I could always have it reset in the future if my preferences change. I got some cheap CZ rings just to test metal color. Please let me know what you think!
