They are quite old, they were my great grandmothers so yes, a couple of the tiny pearls are missing, but I am sure they could be easily replaced and aren't noticeable at all when worn as is. :)
If you look down on this page I have already commented on the pearls. I have no idea of the authenticity of the stones, as I am not a jeweler. I am giving these away on here, not charging money, so obviously they come as is.
