Hi,

I have a wedding ring my grandma left to me and was wondering what the hallmarks can tell me.

Any help would be greatly appreciated.

It appears your ring is marked "TD", which is likely the maker's mark, not a hallmark. Hallmarks designate metal purity and country/city of origin generally, trademarks are to identify the maker. I do not know who the maker is.
