What Is a Probate Jewellery Valuation?

---

A probate valuation is a professional assessment of a deceased person's jewellery, carried out to establish the open market value of each item at the date of death. This figure is used to calculate the total value of the estate for inheritance tax purposes and is reported to HMRC on the IHT400 or IHT205 form.

Unlike an insurance valuation.  which gives the cost of replacing an item with a new equivalent, a probate valuation reflects what the piece would realistically sell for on the open market. The distinction matters — using the wrong type of valuation can lead to overpaying inheritance tax or, worse, an HMRC investigation.

As an executor or administrator of an estate, getting jewellery valuations right is one of your legal responsibilities. This guide covers exactly what you need to know.

HMRC requires that all assets in an estate are valued at their open market value at the date of death. This obligation comes from the Inheritance Tax Act 1984, section 160, which defines open market value as the price an item “might reasonably be expected to fetch if sold in the open market at that time.”

For jewellery, this means you cannot simply guess what items are worth. HMRC has district valuers who can — and do — challenge estate valuations they consider too low. If you undervalue jewellery in a probate return, you risk the estate owing additional tax, interest, and potentially penalties.

There is no legal exemption for “costume jewellery” or items of low value — all jewellery in the estate should be accounted for. However, the level of formality required depends on the value of individual items.

The concept of open market value is central to probate valuations. It represents the price a willing buyer would pay a willing seller, assuming both parties are reasonably informed and neither is under pressure to transact.

This is fundamentally different from the replacement value used in insurance valuations, which reflects the retail cost of buying an equivalent new item. The difference can be substantial:

Example: A diamond engagement ring might have an insurance replacement value of £4,500 (the cost of buying an equivalent new ring from a jeweller) but a probate open market value of just £2,800 (what a willing buyer would actually pay for the second-hand ring). Using the insurance figure for probate would overstate the estate by £1,700 — potentially costing the estate hundreds of pounds in unnecessary inheritance tax.

This is why existing insurance valuations cannot be used for probate. A separate valuation is always required, carried out on the correct basis of value.

 If you're unsure whether an item crosses the threshold, err on the side of caution and get a professional opinion. The cost of a valuation is far less than the potential cost of an HMRC challenge. 

As an executor, managing the jewellery in an estate can feel daunting — particularly if the deceased had a large collection or items of significant value. Here is a clear process to follow:

1. Gather and secure all items. Collect all jewellery from the deceased's home, safe deposit boxes, and anywhere else items may be stored. Photograph everything before moving it, and store items securely — ideally in a safe or with your solicitor.
2. Check for existing documentation. Look for previous valuation certificates, purchase receipts, insurance schedules, and any correspondence with jewellers. These provide useful context for the valuer, though they cannot substitute for a fresh probate valuation.
3. Separate high-value from low-value items. Make an initial assessment of which items are likely to exceed the £1,500 threshold. When in doubt, include the item in the professional valuation.
4. Commission a professional valuation. Find a qualified valuer experienced in probate work. Provide them with all items requiring valuation, the date of death, and any supporting documentation you have gathered.
5. Report values to HMRC. Include the jewellery values on the appropriate inheritance tax form (IHT400 for taxable estates, IHT205 for excepted estates). Keep the full valuation report with the estate papers — HMRC may request to see it.

Probate valuation fees vary depending on the number of items, their complexity, and whether the valuer needs to travel.

Valuation fees are a legitimate estate expense and can be deducted from the estate before calculating inheritance tax. Keep receipts for all valuation work. 

The consequences of inaccurate probate valuations depend on whether HMRC considers the error to be innocent, careless, or deliberate. 

The difference between an informal estimate and a professional valuation can be significant:

 Informal / DIY valuation

• No documented methodology for HMRC
• Easily challenged by district valuers
• Estate liable for additional tax plus interest
• Penalties of 30–100% for careless or deliberate errors
• Executor personally liable if negligent

Professional valuation

• Recognised methodology and documented reasoning
• Defence against HMRC challenges
• Professional indemnity insurance as backup
• Demonstrates “reasonable care” by executor
• Valuer accountable for their professional opinion

Even if HMRC adjusts a professional valuation upwards, the fact that you instructed a qualified valuer demonstrates reasonable care — significantly reducing the risk of penalties being levied against the estate or the executor personally. 

Generally no. Each type of valuation uses a different basis of value — replacement value for insurance, open market value for probate, and realisable value for resale. 

A single valuation certificate states one basis of value, and using it for the wrong purpose can result in overpaid tax, rejected insurance claims, or underpriced sales. 

However, a qualified valuer can often prepare multiple reports in the same appointment, which saves time and may reduce the total cost.

Insurance valuations state the replacement value — what it would cost to buy an equivalent new item from a retailer. This includes the jeweller's markup, VAT, and the cost of sourcing matching stones. Probate valuations state the open market value — what a willing buyer would pay on the second-hand market. The difference is typically 30–50%, because second-hand jewellery sells for significantly less than new retail prices.

Not necessarily. If you need more than one type of valuation, a qualified valuer can examine your items once and produce separate reports for each purpose. This is common when someone inherits jewellery and needs both a probate valuation for HMRC and an insurance valuation to cover the items they are keeping. Ask your valuer about combined appointments to save time and cost.

Insurance valuations typically cost £50–£125 per item depending on complexity. Probate valuations range from £25–£75 per item, with discounts for collections. Resale valuations are usually £50–£100 per item. Most valuers offer reduced rates when multiple items are assessed in the same appointment. All valuation fees for probate are deductible as estate expenses.

Yes, provided they are suitably experienced and  qualified. 

Look for valuers who are members of the Gemmological Association (Gem-A),  Jewellery Valuers Association (JVA), as these professionals are trained in all valuation methodologies. 

Not all high-street jewellers have the expertise for probate or resale work, so always check their credentials and experience with the specific type you need.
