Go to panjiayuan Panjiayuan does a lot of jewelry processing. I saw on Beijing Financial Channel that someone made a ring with filigree craft. It's convenient to take the subway. In the summer, I also saw a company called Laoxijin at the jewelry exhibition of the Old National Exhibition. Their filigree inlay and cloisonne are very beautiful. The flagship store is in Badai, Sanlitun. I haven't been there. If you want to buy finished products, you must ask around there.
