Jewelry appraisal and insurance in the US

A usable report describes the piece in enough detail that it could be identified and replaced without the physical item in hand: the metal and its standard, the cut, weight and quality of any gemstones with the method used to estimate them, overall measurements, condition, any maker's marks or hallmarks present, a period attribution where one is warranted, and clear photographs.

It should also state plainly who prepared it and on what basis, be dated, and state a single value on a named basis rather than a range with no explanation. A report missing any of these elements is harder for an insurer to rely on and harder to use later if a claim is ever made.

Insurance valuations are almost always written on a retail replacement basis, meaning the cost to acquire a comparable piece at retail within a reasonable time. This figure is deliberately conservative from a shopper's point of view and is usually higher than what the same piece would fetch if sold, because replacement assumes buying rather than selling and does not discount for the time or effort a private sale would take.

Fair market value, by contrast, estimates what a willing buyer would pay a willing seller under no pressure, and is the basis used for purposes such as estate settlement or charitable donation rather than insurance. The same piece can carry two quite different, and both legitimate, figures depending on which basis a report is written for, so it matters that a report states its basis explicitly.

Scheduling means adding a specific, individually described item to an insurance policy at an agreed value, rather than relying on a general limit for jewelry that most homeowners and renters policies include and that is usually far too low to cover a fine vintage piece. Scheduling typically requires the written valuation described above, and many insurers will also want photographs on file.

A specialist jewelry policy is a separate option some owners choose instead of or alongside scheduling on a homeowners policy, and it can offer broader terms for loss, theft or damage. Which route suits a given piece and a given owner is a question for an insurance professional rather than for us, since we do not sell or arrange coverage.

Metal and gemstone markets move, and a valuation written some years ago can understate what it would actually cost to replace a piece today even if the piece itself is unchanged. A reasonable interval for revisiting a valuation is every few years, or sooner after any period of significant movement in gold or gemstone prices, and always after any repair, resizing or restoration that changes the piece.

Keeping the original report alongside any updated one is worth doing, since the history of a piece's documentation, including prior condition notes and photographs, can itself be useful evidence over time.

Every piece we sell above a meaningful value includes a detailed valuation and authenticity report prepared by our in-house gemologist, describing the piece fully and stating a valuation on a stated basis, along with our attribution of period and maker where one is warranted. It is prepared by the seller, and we describe it accurately as such rather than presenting it as an independent third-party appraisal.

Some buyers choose to have a piece independently reappraised by a local gemologist after purchase, which is a reasonable step for anyone who wants a valuation prepared entirely outside of the seller, and our report is written with enough detail to make that comparison straightforward.

For any significant piece, keep the valuation report, purchase documentation, photographs taken at the time of purchase, and any prior appraisals in one place, physical or digital, that is easy to produce quickly. This bundle is what most insurers ask for both to schedule a piece and to process a claim, and having it assembled ahead of time saves real difficulty later.
