Having jewellery appraised: costs, types, and how it works

On one and the same piece of jewellery, an appraiser can assign three different amounts without anything being wrong. Each amount belongs to a different purpose and a different concept of value. Knowing this helps one consciously choose the appropriate report and understand why an insurance value is higher than a sale value.

The insurance appraisal establishes the replacement value: what does it cost to acquire a comparable piece today from a specialised jeweller or auction house? Because the new price from a specialist includes retail margin, warranty, and time-to-find, the replacement value is generally higher than what a private individual would ever obtain upon sale. Insurers accept this appraisal for inclusion of the jewel in a valuable items clause.

The sale appraisal establishes the private market value: what would the piece realistically fetch in a calm sale between willing parties, without haste. This value is consistently lower than the replacement value — a difference of thirty to fifty percent is normal. The sale appraisal helps in assessing offers and in consignment or auction discussions.

The inheritance appraisal describes the commercial value: the amount the jewel would fetch on the valuation date between arbitrary third parties. This type of appraisal is used for division among heirs and for tax declarations. Important: this paragraph is for informational purposes only, not tax advice — for questions about declarations, threshold amounts, and concrete procedures, we refer to a notary or tax advisor familiar with the current rules.

Why three amounts on one piece is not an error: the appraiser does not measure 'the' value, but the value in a specific context. Replacement from a specialist, sale in a calm market, and transfer in a legal context are three different situations with three different pricing mechanisms. A report that states a single amount without mentioning the purpose is incomplete.

Concrete rates vary per appraiser and region and change annually; this guide deliberately does not state amounts from specific parties. However, the calculation logic can be described, and this helps to weigh a quote without being surprised.

For simple work (a single gold ring, a plain necklace, a brooch without complications), most appraisers charge a fixed fee per piece. For complex work (many gemstones, unusual construction, provenance research, signed work requiring source consultation), an hourly rate or a surcharge on top of the tiered rate applies. For larger collections, the cost per piece often decreases significantly; always request a quote in advance based on photographs.

The rule of thumb: an appraisal is worthwhile primarily when there is a concrete reason. Someone who insures above the household contents sub-maximum, who divides an inheritance, or who suspects significant value (rarity, signed work, unusual gemstone) will recoup the costs in certainty or a more accurate payout. Someone who 'just wants to know what it's worth' is almost always better off with a free value estimate and only appraising if there is reason to do so.

For a larger collection, also factor in travel time or shipping costs. An appraiser who comes to your home, or takes a collection for examination, will include these in the quote. Inquire in advance if photographs can facilitate an initial selection remotely — then you only appraise what truly matters.

In the Netherlands, 'appraiser' is not a legally protected profession, but 'sworn appraiser' or 'certified jewellery appraiser' is — this refers to someone who is affiliated with a professional association, has passed an examination, and adheres to codes of conduct. The primary resource is the Federation TMV (Appraisers, Brokers, and Auctioneers), where you can search by discipline (jewellery). Insurers generally only accept reports from affiliated appraisers.

Jewellers can also have appraisal authority. In such cases, usually one person within the business holds the diploma; not every employee may sign reports. Ask for the name of the appraiser on the report and, if necessary, their affiliation with an association.

The difference with a free estimate: an estimate is a valuation without legal status, an appraisal is a stamped and signed report accepted by insurers, notaries, and the Tax Authorities. An estimate is fine for determining whether further research is needed; it does not replace an appraisal. For the complete distinction: appraisal or estimate.

Beware of conflicts of interest: someone who appraises the same piece and then purchases it has a structural interest in a lower value. For amounts of significant size, it is customary to separate the appraisal and any purchase among different parties — or to explicitly agree that the appraised amount is also the minimum purchase offer.

A good report is self-explanatory: someone who has never seen the piece should be able to precisely deduce its characteristics ten years later. The standard components include a description (type of jewellery, period, style, condition), one or more photographs from top and side views and of any hallmarks, weights in grams and finenesses of the precious metal, gemstone specifications where applicable (colour, clarity, carat weight, cut), the value and purpose (insurance, sale, inheritance) explicitly stated as such, and the date with the appraiser's name and signature.

For special pieces, provenance is appropriate: who owned it, where was it made, what sources were consulted. For signed work, a description of the signature and its location is included. For gemstones above a certain carat weight, appraisers often refer to a laboratory report (e.g., GIA or IGI) instead of assessing the gemstone themselves.

Insurers require a recent appraisal because gold and gemstone prices fluctuate and because the condition of a piece changes. Insurers generally apply a maximum age for the report; this period is not uniform, and with significantly increased precious metal prices, re-appraising earlier is advisable to prevent under-insurance. When entering into the policy, explicitly ask how long the report remains valid with this insurer.

What to check yourself in a report: is the purpose explicitly stated ('replacement value for insurance purposes'), are the hallmarks depicted, does the gemstone carat weight match what you observed upon delivery, and is the signature legible? A report without purpose or without a photo is incomplete, even if it states an amount.

Good preparation saves time and money. Photograph each piece before handing it over (top view, side view, macro shot of hallmarks) — this way you have your own record in case anything goes wrong. The precise method is detailed in photographing jewellery for appraisal. Weigh the pieces on a kitchen scale and note the weight; this is not an appraisal but helps in scanning the quote.

Gather what you know about provenance. Purchase invoices, family stories, old photos showing the piece being worn, previous appraisal reports — anything that provides provenance can influence the value. For unknown pieces, first estimate the age using the dating guide so you can find the right specialisation (art deco requires different knowledge than Dutch regional silver).

Before scheduling an appraisal, consider a free value estimate. This is not just a preliminary step for show but a filter: you only appraise what is worth appraising, and you go to the appropriate appraiser (vintage specialist versus diamond specialist versus silver specialist). For larger collections, this filter can quickly save several hundred euros.
