Jewelry Maker’s Marks, hallmarks, inventory marks, sales records, gemological laboratory certificates and fitted jewelry boxes all contribute to jewelry provenance, especially when establishing who made the item and when. Appraisals and letters of authenticity from the jewelry house of manufacture are also valuable in authenticating provenance. Written statements from previous owners, signed and authenticated, can be considered, although weighted as to authenticity.
The origin of a gemstone (i.e. Colombian emerald) and the name of the designer or manufacturer of a jewelry piece (i.e. Tiffany & Co.) are also referenced by some as provenance.
