Next to the Hotel Bayrischer Hof on Promenadenplatz there is a great
crafts gallery. They usually do special exhibitions as well as have
a large stock of german designer jewelry, of which they have some in
the shop window. Some of the small galleries in Schwabing might have
some jewely on show. Also in Schwabing on Hohenzollernstrasse there
is a nice jewelry shop selling interesting designs. The fine arts
academy have a jewelry program ( Otto Kuenzli) they might have
something on too.
Munich is a beatiful place to visit, even in winter; so enjoy!
