Jewellery supply stores - Munich

I am going to Munich for the Mineralientage end October. Any locals
who can suggest where to find jewellery supply stores in Munich?

hi eddie its been a few years since i lived in munich, but from memory: there is a place near viktualienmarkt right in the centre. if you walk past the fish stalls at the market towards frauenstrasse you get to a few more shops and a vegetarian cafe if memory serves.right in the corner there in the first floor there is a good place for tools(you need to ring a bell i think). i dont think its particularly cheap. have fun in munich- its a great place. katja
