I just purchased this pearls, the seller said it comes from Burma. It's the drilled natural pearls. I need to tell story more but my English is not good.
The colors are lovely in your newly acquired pearls. They'd make up into a neat set or cluster of flowers on a pendant because of their uniform sizes.
It was fun to see so many photos. Any more details you could provide would be of interest...details like freshwater, saltwater, cultured, non-cultured, etc.
