Have you tried clear Vinegar ?
Anything you try should be done in a small inconspicuous place and then wait a few days to observe, before proceeding.

Spray bottle of Bleach and water but not too strong for your skin and wear gloves.

It can get complicated with pourous stones like marble. It would help to figure out what caused the stain but if it is not a surface stain you will likely need some sort of poultice to draw out the stain. You may have to do this many times before you get the desired results. Surface cleaners won't work no matter how hard you try of the stain is below the surface (which it likely is). Apply a good sealer if you ever get it clean
