I assume you are asking because they are ultra small. You might ask Hisano Shepherd of little h if she is interested in tiny natural pearls for her jewelry line.
Those look pretty small, around 2mm. I'd look at old victorian jewelry (seed pearls, example below) to get some ideas. You could split them in half and set them in an array of styles. Or you could set them whole. I'd be interested in buying some if you offer any for sale, for my natural pearl collection. Good luck!
The first photo, mid-top left pearl that looks like an eye...I'd seriously keep that and set it as an evil eye pendant or charm. But what an impressive lot of pearls you have. I too would love the back story!
