The offer of the author's jewelry auction on July 1, 2021, contains objects with a very special provenance.

The collection includes selected works by Yasuki Hiramatsu, Hubertus von Skal, Friedrich Becker and many other author's jewelry artists from a period of almost 40 years. n the second part of the catalog, another 60 works from other provenances complete the offer. Here, too, important representatives of the author's jewelry scene can be found, such as Giampaolo Babetto, Erico Nagai and Hermann Jünger himself.
