Wedding planning

I am having trouble finding a wedding ring. I wanted an old, simple ring. Unfortunately the one I've been most attracted to so far turned out to be from the 1930's and platinum. Therefore unaffordable.

I've thought about having a new ring made. However, I have ethical issues with mining.

Any brillant suggestions?
