Engagement rings? HELP!

Ch

These are the beautiful rings my boyfriend of 4 and a half years has brought me of the last few years.

The second photo is my promise ring set he got me the year after we first got together.

I think we might get engaged this year! He asked me to pick out what type of ring I like, it's soo hard to choose rings that will match these rings.

We are both 22 years old and he is honestly the best man I could ever ask for, we have been together since high school.

Any suggestions?! I only wear gold , so it makes it even harder!!! HELP!
