My wedding rings are somewhere between. They look white next to yellow and next to white they look golden but not too much.
I picked my rings from some my FIL had cut and set. I love my rings due to that fact alone.
Go find a white wall, not cream or beige but white. Put your arm out like you are going to hitch hike with the elbow towards the wall.
Does your arm look golden or pinkish. Can you see lots of veins that seem to be close to the surface? Is your skin thicker where just the skin shows? Trying to decide if you have a warmer skin tone or a cooler skin tone might be what helps you to decide.
A cooler skin tone looks good in the white or something not so yellow. A warm skin tone looks better in the yellow tones.
If you do find a set you like then don't let the metal in it determine if you get it or not. You may be able to order it in a different tone but it might look just fine the way it is.
