Probate Jewellery Valuation: A Guide for Executors
When jewellery forms part of an estate, executors need an accurate open market valuation for probate and inheritance tax. Here is what that involves and how it differs from an insurance valuation.

What a probate valuation is
A probate valuation establishes the open market value of an asset at the date of the owner’s death. For jewellery, that means what the piece would realistically have sold for between a willing buyer and a willing seller on that date, not its replacement cost.
Executors need this figure to report the value of the estate to HM Revenue & Customs and to calculate any inheritance tax due. An accurate valuation protects executors, who are personally responsible for getting the estate’s figures right.
Open market value, not insurance value
This is the single most important point for executors. A probate valuation uses open market (resale) value, which is typically far lower than an insurance replacement valuation the deceased may have held.
Using an old insurance valuation for probate can significantly overstate the estate and the inheritance tax due. The two figures answer different questions and should never be used interchangeably.
Who should carry it out
For valuable or complex pieces, HMRC expects a professional valuation by a suitably qualified valuer, for example a member of a recognised professional body, or a specialist at an auction house. The valuation should be itemised, dated to the date of death, and based on comparable market evidence.
For significant diamonds and coloured stones, grading and origin reports (GIA, IGI, Gübelin, SSEF) strengthen the valuation and support the figure if HMRC queries it.
Releasing funds during probate
Estates are often asset rich but cash poor before assets are sold or distributed, yet inheritance tax can fall due before probate is granted, and estates incur costs along the way.
Where beneficiaries wish to keep jewellery rather than sell it, a short-term loan secured against the pieces can provide liquidity to meet a tax bill or estate costs, with the option to redeem the jewellery once funds become available. This keeps treasured pieces in the family while solving the timing problem.
