My boyfriend found these on the bottom of the lake while fishing this past weekend. 84 pearls, hand knotted, blemishes, indents, and chipping. They have an orangish [/ATTACH] [/ATTACH] tint on some of them. All diff looking, and some have started to chip, one has no top layer on it, and is still shiny, and when I rub them together it leaves a white mark and I can wipe it off. They do feel gritty along my tooth. It has a barrel clasp and is heavy. Not sure if they are fake or real, and how long they have been sitting on the lake floor. Can a real pearl loose its top layer? The one that is missing all of it, is whitish and looks like it has a rough surface, but is has an earadesance? shiny layer. HELP...........can anyone help with these pictures and have any ideas on wether or not they are real?
