All kinds of books in several languages ??on the subject; antique jewelry

We are a clearing our house.. When I was at my stack of books in all subject antique jewelry, I actually had to laugh. Just like my jewelry collection is this collection of books about run out of control. But ... of course very interesting and good to advise and very instructive.
The two books that I have on a separate photograph I most learned and are therefore highly recommended. If you have questions you know to find me !!
