Hi, my fiance's mom recently gave me a set of pearls for Christmas. She says they are freshwater pearls. I am just interested to know more about them, like where they are from, and in particular, you can see many of the pearls have these rings etched in their sides - I don't mind it, but I am just wondering what causes that. I don't care about the value because I am going to wear them, I just want to learn everything I can.
Thanks!
Thanks!
