I am 30 years old and my passion is working with ancient techniques
(granulation, filigree, opus interasile, stone carving etc.) using
non-sophisticated tools. I also collect antique books about
goldsmithing and I am also interested in books published in other
countries. I’d like to exchange views, hints, tricks, recipes etc.
about all kinds of jewelry making.
