Re-appraisal Cycle — Keeping Insurance Values Current
Re-appraisal Cycle — Keeping Insurance Values Current
The two-to-three-year interval at which jewellery appraisals should be refreshed to reflect changing market conditions
The re-appraisal cycle is the recommended interval at which jewellery appraisals should be refreshed to reflect current market values, typically every two to three years. Gemstone and precious-metal prices fluctuate in both directions; outdated appraisals can leave a piece under-insured if values have risen or saddle the owner with excessive premiums if they have fallen. The American Society of Appraisers, the National Association of Jewelry Appraisers, and the major insurance underwriters all advise periodic re-appraisal as a routine element of jewellery ownership.
Why values move
Several distinct factors drive the need for periodic re-appraisal. Gold and platinum prices move on macroeconomic and currency cycles, with sustained moves of 30 to 50 per cent over two-to-three-year windows not uncommon over the past two decades. Coloured-stone values shift on supply conditions: closures or discoveries at major mines, sanctions affecting specific origins, and shifts in fashion can move prices materially over short periods. Diamond prices have moved both ways since the emergence of laboratory-grown diamonds at scale, with natural-diamond pricing under pressure in some categories and strengthening in others.
Beyond market movement, the piece itself may change. Wear, repair, re-tipping, re-polishing, or the substitution of a centre stone all affect appraised value. Significant alterations should trigger a re-appraisal independent of the routine cycle.
Insurance implications
Most jewellery insurance is sold on either an agreed-value or a replacement-cost basis. Agreed-value policies pay out a fixed sum on total loss, regardless of whether replacement cost has risen since the appraisal. Replacement-cost policies pay the cost of replacing the lost piece with one of like kind and quality at current market prices, subject to the policy limit. Either model relies on a current appraisal: under-stated agreed values produce under-insurance, and replacement-cost limits set against stale appraisals can fall short when the time comes to replace.
Jewelers Mutual, Chubb, and other specialist underwriters typically request updated appraisals every three to five years; some policies require re-appraisal as a condition of continued coverage. Some insurers also offer escalator clauses that adjust coverage limits in line with a reference index, but the most reliable mechanism remains a fresh appraisal from a qualified appraiser.
What a current appraisal should contain
A current appraisal documents the piece in sufficient detail to permit identification, valuation, and replacement: weight and dimensions of significant stones, cut and clarity grade, treatment status, origin opinion where supportable, mounting weight and metal composition, photographs in standardised lighting, and a stated valuation methodology and intended use. The valuation should distinguish replacement value, fair market value, and liquidation value where the distinctions are material. The American Society of Appraisers Uniform Standards of Professional Appraisal Practice (USPAP) sets the methodological framework most reputable American appraisers follow.
In the trade
For working jewellers and dealers, the re-appraisal cycle is one of the natural points of customer contact in the post-sale relationship. A jeweller who proactively reaches out to clients on a two-to-three-year cycle to recommend re-appraisal demonstrates ongoing service, surfaces opportunities for cleaning and inspection at the same visit, and protects the client's insurance position. Many jewellers offer in-house appraisal services or refer clients to independent appraisers; in either case, the cycle benefits both the customer relationship and the longevity of the piece.
