Hi everybody, I recently found this small old case of what looks to me like some type of pearl but I am not sure because I'm no to familiar with gems and pearls. They were left in my basement hidden away by the previous owner. As you can see some of them have brown dust on them but it seems like it will come right off with some proper cleaning. I have taken some pictures and I was wondering what all of you think, and if you guys could help me to distinguish what these things actually are and if the have any value? Thanks so much!
