I have two marbles that are badly damaged. One is a large figural one with a rabbit that is so beat up I can barely see inside and it has a large piece missing ... If ground down and polished it could end up just large enough to encase the rabbit well enough. The other is a very large german marble that isn't missing any glass but has lots of dings that cannot be seen through. I would like to enjoy these and wonder what my options are. Is it something I can do myself? Anyone affordable and reliable? I don't have a lot to spend... But its a shame to not be able to see the designs.
