Jewellery Valuations for Insurance: What Independent Jewellers Need to Know

Most jewellers treat the insurance valuation as a favour — a tidy certificate the customer needs for their contents policy, knocked out at the counter as a goodwill gesture with a purchase. That framing is exactly where the risk hides. A valuation is a professional opinion of value, signed in your name, that an insurer and a loss adjuster will rely on years after you've forgotten writing it. The customer reads the number and relaxes. You are the one who has to stand behind it.

Get comfortable with that reframe first, because everything else follows from it. This is not paperwork. It is a piece of expert evidence you author.

"What it's worth" is the wrong question

The single most common lay error is assuming a piece has a value. It has several, all legitimate, and they can differ by a large multiple.

An insurance valuation is prepared on a replacement basis — what it would cost to buy an equivalent item at retail, today, in the open market. For modern jewellery that means new-for-old: the full retail cost of sourcing or remaking a comparable piece new. For antique, period or handmade items that can't sensibly be replaced new, valuers use a secondhand replacement value — the realistic cost of finding a like-for-like previously owned piece.

That figure is deliberately high, because it reflects retail replacement, not what the customer paid and certainly not what they'd get selling it back. Contrast it with:

• Probate / open-market value — what the item would fetch in a sale between willing parties, used for estates and HMRC. Typically far lower than insurance replacement.
• Resale or trade value — what a dealer would actually pay. Lower again.
• Fair-value figures for divorce or division of assets, which have their own conventions.

A customer who sees a £6,000 insurance valuation and expects £6,000 when they sell has misunderstood the document. Part of your job is stating the basis of valuation on the certificate itself, in plain terms, so nobody confuses the number you gave them with a price you'd honour.

"Valuer" is not a protected title

Here is the uncomfortable fact the trade rarely says out loud: in the UK, valuer is not a regulated or protected title. Unlike solicitor, architect or chartered surveyor, anyone can print the word on a business card and type a figure onto a certificate. There is no legal barrier stopping the least experienced person in your shop from producing an insurance valuation this afternoon.

Which is precisely why the professional infrastructure matters. Because the title guarantees nothing, the weight of a valuation comes entirely from the competence and credentials standing behind it. An insurer challenging a claim will ask who valued the item and on what authority. "The Saturday assistant, from the till receipt" is not an answer that survives a loss adjuster.

The competence a proper valuation demands is real and layered: you need to identify metals and their fineness, grade diamonds and coloured stones, distinguish natural from treated or synthetic material, recognise period and maker, and translate all of that into a defensible retail figure. Any one of those going wrong makes the number wrong.

The qualifications and bodies that actually mean something

Because nobody polices the title, the recognised qualifications do the work. The pathway most credible UK valuers follow runs through a few names worth knowing:

• Gem-A (the Gemmological Association of Great Britain) awards the two most respected post-nominals in the trade: FGA (Fellow, the gemmology diploma) and DGA (the diamond diploma). These prove you can actually identify and grade what's in front of you.
• The Institute of Registered Valuers (IRV), run by the National Association of Jewellers, is the long-standing home of the appraisal profession. Its members work to a Code of Practice, commit to continuing professional development, and undergo periodic professional review rather than qualifying once and coasting. The entry step is the Level 3 Foundations of Appraisal Practice certificate; full membership expects gemmology and diamond-grading qualifications, a recognised valuation qualification and several years' hands-on experience.
• The Jewellery Valuers Association (JVA) and the Guild of Valuers and Jewellers serve a similar purpose — bodies run for valuers, with membership gated behind recognised gemmology, diamond-grading and valuation qualifications plus real experience.

The common thread is that a serious valuer is a gemmologist and a trained appraiser, keeps learning, and is accountable to a body that can be pointed to. If nobody in your shop holds those credentials, the honest and safer move is to refer valuation work out rather than improvise it.

The number is a legal opinion, not a guess

A valuation you sign is a professional service, and the law expects it to be carried out with reasonable skill and care. That is the general standard: your work is judged against what a competent, responsible body of opinion within the profession would consider acceptable practice. Fall short of that — misidentify a synthetic as natural, grade a stone carelessly, pull a retail figure out of the air — and you have exposure.

This is exactly why proper valuers carry professional indemnity insurance, and why they qualify their certificates: stating the basis of valuation, the limits of a visual examination without unmounting stones, and the date the opinion was formed. Those are not weasel words. They define the scope of what you're standing behind, which is the difference between a defensible opinion and an open-ended promise.

Treat every certificate as something that could be read out in a dispute, because occasionally one is.

Under-value and over-value both bite

Jewellers instinctively worry about pitching too low. Both directions carry risk.

Under-value, and the customer is quietly underinsured. When they lose the piece, the payout falls short of replacement, and the person who told them what it was worth is the obvious place to point the finger. Many policies also apply an average clause — underinsure the whole schedule and every claim is scaled down proportionately.

Over-value, and you've inflated their premium for years and potentially misled them about what they own. An over-cooked figure that a loss adjuster later marks down looks, at best, like incompetence and, at worst, like you were flattering a sale. Neither reputation is one you want attached to your certificates.

The defensible position sits in the middle: a figure you can evidence from real retail comparables, on a clearly stated basis, that you'd be content to explain to a stranger.

Valuations go stale faster than owners think

A valuation is a snapshot of one day's market. Precious-metal prices have risen sharply this decade — gold in particular — so a certificate written even a few years ago very likely understates today's replacement cost. The customer's policy schedule still shows the old figure; the shortfall only surfaces at the worst possible moment, when they claim.

The broad industry guidance is to revalue roughly every three years, and sooner after a sharp market move. That's a genuine service you can offer existing customers rather than a chore — a periodic review that keeps their cover honest and brings them back through your door. Frame stale valuations as the real exposure they are, and revaluation stops being an upsell and becomes obvious sense.

Charge for it — and never on a percentage

Valuation is skilled, time-consuming, liability-bearing work. Giving it away trains customers to see it as worthless and quietly subsidises the risk you're carrying. Charge for it, openly, as the professional service it is — typically a flat fee per item or an hourly rate, with the going rate for a straightforward piece somewhere in the region of £50 to £150 depending on complexity.

One rule is close to absolute in the profession: never charge a percentage of the valuation figure. Tying your fee to the number you write creates a direct incentive to inflate it — the textbook conflict of interest — and it's the fastest way to make every certificate you've ever signed look compromised. Flat fee or hourly, stated up front, independent of the result. That independence is the whole point.

The bottom line

An insurance valuation is not a receipt, a favour or a sales sweetener. It is a signed professional opinion of replacement value that an insurer will lean on and a court could read, and the liability for the number is yours, not your customer's and not their insurer's. Know which basis you're valuing on, make sure real qualifications sit behind the figure, price the work as skilled work, keep valuations current as prices move, and never let your fee ride on the answer. Do that, and the certificate on your letterhead becomes what it should be — a mark of your authority, not a hostage to it.
