All the pieces came in a original hoof type box with all the various attachments. The main piece has the sissi emblem design & the gold bracelet woven in fine gold mesh looks a work of art in itself.
All sounded OK to me, with a very genuine owner & correct provenance. I'm not sure its their job on the show to authenticate, but the expert was really drooling over this bracelet & so was I.
Having said all that I would like to point out I know absolutely nothing about jewelry.
