Engraved Tankards

I would like to get my wedding ring from her late husband engraved inside. It is a white gold ring. Found several places that engrave trophies, tankards, etc., but not inside a ring. Ideally, I would not want to burn an amount of very long periods. Can anyone help?

Any decent independent jeweler should be able to arrange for you. Do not bother with chains like H Samuels and Ernest Jones.
