For those of you with a solitaire setting.........

Is it white gold or platinum?

Im considering changing my setting. I have a round 1.75ct with two baguettes (one on each side)in a white gold setting.
I lost a baguette not too long ago( and I hear very common) and instead of going to a where it was originally made, I went to a local jeweler I deal with who replaced it with but with not an exact match because I freaked and couldnt look at it like that. (I can get it fixed)
Now I am soon going to be looking for wedding bands.
So I figured I may do a change to the solitaire.
I noticed they go with any band.
Would u recommend platinum or white gold?
I hear a solitaire setting makes the diamond appear larger That could work.

TIA!

ETA: Anyone with pics...if you could add, that would be great!
