A valuation built for a real decision
A signed jewel can carry value beyond the diamonds and metal. Reference, age, condition, service history and paperwork matter.
The first review studies hallmarks, serial numbers, clasp details, invoices and boxes when available.
This helps decide whether the piece should be positioned as jewellery, as a diamond dossier or as a collectible maison object.
