Valuing an estate’s contents means putting a figure on everything a person owned, from the furniture and the paintings down to the watch on the bedside table. Most of it can be worked out with care, patience and the right evidence. Jewellery is the category that tends to stop an executor in their tracks. A ring with a stone in it feels like something you could get badly wrong, and the instinct is to find someone qualified, pay them, and be safe.

It is worth considering exactly what HMRC requires of an executor. What it asks you to provide is a value. It does not ask for a valuer. The two are not the same thing, and the gap between them is where estates tend to overspend.

The Real Question Is What the Jewellery Is Made Of

Whether you need to see anyone depends almost entirely on the materials, not on the number of pieces.

Gold is weighable and hallmarked. A clear photograph of the hallmark and a reading off a set of scales captures the same information an assessor would capture in the room, because the value of a gold piece with no significant stones is largely the metal it contains.

Gemstones are where the received wisdom kicks in. Everything you read online will tell you that a diamond or a coloured stone needs the eye and instruments of a gemmologist to judge cut, clarity, colour and carat, and that no photograph can replace that. It is true, but only above a certain size. On the small, modest stones found in most jewellery boxes in the UK, the difference between a fine grade and a poor one is only a matter of pounds, and paying for that scrutiny buys the estate nothing.

Once a stone is large enough for the grading to swing the value, a gemmologist earns the fee. Below that, it does not change the answer.

Typical jewellery boxes comprise gold for the most part: chains, bands, odd earrings and worn pieces, with a handful of stone-set items among them and fewer still that clear that threshold. So most of the value in a typical estate can be assessed without a house call, and the effort concentrates on the few pieces where the stones are genuinely significant.

Who Values Jewellery for Probate, and How They Charge

You have five realistic routes, and each has a legitimate case.

1. High street jewellers will usually take the items in over the counter and charge per item, which suits a small number of pieces you can carry in. Quite often their valuations are insurance valuations (in terms of level of detail) so you will often pay over the odds all things considered. Expect to pay £75-100 per item.
2. Freelance valuers and dealers tend to come to you, which is convenient when there is a lot to look at or the items should not leave the house, and they generally charge by the hour rather than by the piece. Expect to pay £300-500 per hour.
3. Auctioneers also tend to charge by the hour, sometimes sending someone out and sometimes assessing what is brought in, and many offer the service as part of their wider business. Auctioneers often charge around £150-500 per hour.
4. Online photo-based valuation, which is what we do, works from good photographs, hallmarks and weights. At Swift Values we offer jewellery valuations from £30 for a single item and £60 for multiple items. We also offer home/office visits from £298 per hour.
5. Self-declaration, the executor arriving at their own figure, is what most people actually do. None of these is wrong in principle. The right one depends on what is in the box and what the estate needs the figure for.

Cost Versus Value: When Seeing Someone Is Worth It

An in-person valuation running to several hundred pounds is proportionate for a collection worth tens of thousands, and out of proportion for one worth around £2,000. We regularly see bills for a face-to-face jewellery valuation that run into the hundreds on a collection worth roughly £2,000, because of the paperwork produced and the people involved. It can cost more to value the jewellery than to value the entire house it sat in.

Auctioneers have historically offered valuations partly as a route to future sales, which is a perfectly sound business model when a family intends to sell. It is not aligned with an executor who is keeping everything.

Where inheritance tax is due, the estate pays 40% of whatever it declares, and that shifts the whole calculation. A valuation that corrects an inflated figure does not just cost less than an expensive alternative, it pays for itself. A £300 in-person valuation covers its cost the moment it knocks £750 off the declared value, and a £60 online valuation only has to find £150. Estates routinely overvalue their contents by far more than that, usually by confusing an insurance replacement figure with open market value, so in practice the cheaper the valuation, the smaller the correction it needs to make to have already paid for itself.

What IHT407 Actually Asks For

IHT407 asks for details of any individual items of jewellery valued at £1,500 or more, with a professional valuation enclosed if you have one, as set out in HMRC’s internal guidance on IHT407.

Lower-value and costume pieces can be grouped together on a single line rather than listed one by one.

Our Honest Opinion

Our online service suits the majority of UK estates, and for most executors it is far better than attempting the figure yourself. It has its limits, though, and where a piece warrants proper examination in person, we say so and escalate it rather than putting a speculative figure on it.

If you are an executor working out whether your parent’s jewellery justifies a valuer at all, our jewellery probate valuation is a sensible first step, and if what you send us needs a specialist in the room, we will tell you.
