Jewellery in Budapest, Hungary and Vienna, Austria

Hi all,

I am lucky enough to be going to Hungary and Vienna in late-July to
early-August and I was wondering if anyone out there in computerland
knew of:

a) Good/cheap jewellery tool suppliers in the region. I am
especially interested in a rolling mill.

b) Interesting jeweller’s shops in the region.

c) Good gem suppliers in the region.

d) Any exhibitions that may be on at that time in the region.

Thanks
(crossed fingers)
