Start with the purpose of the valuation
The same jewel can have several values depending on the question being answered. A current purchase offer is different from the retail price of a comparable new piece, and a formal expert report may use another basis defined by its assignment.
Before arranging a service, decide whether you want to sell, insure, divide or formally document the jewellery. This helps you avoid paying for a report you do not need — or obtaining only a purchase offer when an institution requires a formal document.
A valuation for the purpose of selling
A non-binding valuation at a jewellery buyer answers a practical question: what can be offered for this piece if it is sold now? The assessment considers:
- the type, purity and weight of the precious metal;
- the authenticity and quality of diamonds or other gemstones;
- condition, completeness and workmanship;
- possible antique, branded or collector value;
- the current metal market and real demand for the piece.
The result is an explained purchase offer. Our valuation at Zlato v Praze is free, non-binding and does not oblige you to sell. It is not a formal expert report and should not be presented as an official document.
What is a formal expert report in the Czech Republic?
A formal expert report is prepared for a defined assignment by an authorised expert, expert office or expert institute. The Czech Ministry of Justice maintains a public register of experts where you can verify authorisation and specialisation.
The report is normally written, follows formal requirements and is prepared for the purpose stated by the client. It is paid work; price and timing depend on the number of objects, testing required and scope of the assignment. If a court, notary, insurer or another institution requests a report, ask it which field, specialisation and type of value are required.

When a free valuation is enough
If you want to know whether to sell and what current offer is realistic, a free valuation is usually the appropriate first step. It can cover gold and silver jewellery, diamond rings, antique pieces and damaged items. Once you know the offer, you remain free to accept or decline it.
When to contact an authorised expert
Consider a formal expert if a third party explicitly requires a written document — for example a notary, court, insurer or parties to a property settlement. Confirm the exact requirements with the recipient before commissioning the report. A purchase valuation is not a substitute for such a document.
Why the figures can differ
A difference between a purchase offer, insurance value and original shop receipt is not automatically an error. Retail price includes manufacture, distribution, margin and taxes. A purchase offer reflects the current value and resale potential of the specific used piece. A formal report follows its assignment and selected valuation basis.
What to bring
- the jewellery and any loose parts or stones;
- diamond or gemstone certificates;
- original box, receipt and documentation, if available;
- information about provenance, age or maker;
- valid identification if you later decide to sell.
Avoid aggressive cleaning before the visit. See our guide on preparing jewellery for valuation.
