I have a pearl that has been sitting in my jewelry box for 10 years now. I received it as a gift undrilled and would like to get it drilled for a ring. Would it be a good idea to store this pearl in salt water in order to remoisten it for drilling? I've searched all over the internet and can't find any information on it. I haven't stored it in plastic or heat. It has sat in my jewelry box since i got it. Any information I can get would be super helpful!
