I need some vintage looking jewelry items created

I would like to buy some vintage items for my grandmother, who lost most of her jewelry in a house fire. I think these pieces can only be replaced at a vintage jewelry shop. So far, I have not been able to find anything similar to what my grandmother lost. So now, I am considering the possibility of having someone create these jewelry items from scratch. Do you think this will be possible? And, if so, what would I need to do to make it happen?
