Jewellery in Europe

A recent post made me think I could ask Ganoksin members about
exhibitions and museums in Europe. I am travelling next May/June and
would like to see jewellery specific exhibitions and museums if
possible. I will be visiting Denmark, Germany, France, Italy and
Turkey. Capital cities and smaller towns so planning around what is
available would be okay. I am travelling to Pforzheim as I know of
one museum there but also many interesting tool manufacturers.

Thanks in advance
