Hi Isaac
To do
anything online, you are going to need pictures.
There are natural pearl people who check in here regularly. De Beers is diamonds right? Most jewelers and/or diamond people do not know much about pearls. Do you know when your Gt G-mo got the pearls? or When was she born?
I don't think anyone will venture much of an opinion without close up photos. You need to find a friend with a digital camera that has a macro setting. Close up is what we need.
