Insuring your vintage jewelry

A standard homeowners or renters policy typically includes a modest amount of coverage for jewelry as part of your general personal property, often with a per-item or per-category sublimit that is far below the value of a fine antique piece. Coverage under these policies can also exclude common causes of loss, such as a stone simply falling out, or require a police report for theft.

A scheduled personal articles policy, sometimes called a jewelry floater or a personal articles rider, insures a specific named piece for a specific value, usually with broader coverage that includes accidental loss and mysterious disappearance, and no separate deductible for that item. Because it covers the piece by description and value rather than as part of a general category, the insurer will generally ask for documentation before adding it.

A replacement value policy pays out what it costs to replace the piece at the time of loss, which an insurer determines based on current prices. For a unique antique piece, that can be a difficult and sometimes contentious process, since there may be no directly equivalent piece on the market.

An agreed value policy sets the insured amount in advance, based on a valuation you provide when the policy is written, and pays that amount without a separate negotiation at claim time. For one-of-a-kind antique jewelry, an agreed value policy is generally the more predictable option, though availability and terms vary by insurer.

Whichever type of policy you choose, your insurer will want a written report describing the piece in enough detail to identify it and support its insured value. A thorough report typically includes the metal and its standard, a description and measurement of each stone including its type, cut and estimated weight, an assessment of any treatments, the piece's approximate period and condition, and clear photographs.

Every piece we sell above our high-value threshold comes with a detailed valuation and authenticity report prepared by our in-house gemologist, describing the metal, stones, measurements and condition in this level of detail. We prepare it as the seller's own assessment for your records and for your insurer to review, and it is not an independent third-party appraisal, so check with your insurer which form of documentation they require and whether they accept a seller's report or want a separate appraisal.

Photograph every valuable piece clearly, including any hallmarks, and keep the images somewhere other than with the jewelry itself, alongside your invoice and any valuation report. This is the paperwork you will need first if a piece is ever lost, stolen or damaged, and it also makes it far easier to update a valuation later.

Keep a simple written inventory too, noting where and when each piece was acquired and what documentation exists for it. It sounds unnecessary until the day you need it.

Gold, platinum and diamond prices move, and an antique piece insured at its purchase value five or ten years ago may be significantly under or over insured today. Review scheduled items with your insurer every few years, and sooner if there has been a large move in precious metal prices or if the piece has had significant work done to it.

If you inherit or are given a piece with no existing documentation, it is worth having it assessed and valued before you insure it, rather than guessing at a figure.
