Inherited Jewelry: What to Do Before You Clean, Sell, or Insure It

1. Keep the piece and its story together

• Save boxes, receipts, repair slips, certificates, old appraisals, handwritten notes, and photographs showing who wore the item.
• Record the name of the person it came from and any dates, locations, or jewelers associated with it.
• Do not discard a worn box or replace a tag until it has been photographed; provenance can live in ordinary packaging and paperwork.

2. Make a photo inventory before cleaning

• Assign each piece a simple inventory number and photograph it beside that number.
• Capture the front, back, side profile, clasp or hinge, setting, damaged areas, and every stamp or signature.
• Use soft indirect light, avoid digital zoom, and add a ruler or known-size object in a separate scale photograph.
• Record weight and dimensions only if you can do so without forcing clasps, removing stones, or opening a watch case.

Photographing first preserves evidence that cleaning, polishing, repairs, or handling could alter.

3. Pause before using a DIY cleaning method

GIA cautions that light, heat, chemicals, and ultrasonic cleaners are not safe for every gemstone or setting. Treatments, fracture-filled stones, glued components, fragile enamel, foil backs, loose settings, and vintage construction can all change what is safe.

• Store pieces separately in soft, dry compartments to reduce scratching and tangling.
• Do not use toothpaste, bleach, acids, abrasive polish, boiling water, steam, or an ultrasonic cleaner on an unidentified piece.
• If a stone moves, a prong catches, a strand is frayed, or the surface is flaking, stop handling it and seek a qualified repair professional.

4. Read marks as claims that need context

A fineness number such as 585 or 925 can indicate a claimed precious-metal standard. It does not by itself prove when, where, or by whom a piece was made. In the UK system, for example, a complete hallmark includes a sponsor or maker mark, a metal-and-fineness mark, and an assay-office mark.

• Transcribe exactly what you see, including letters, symbols, spacing, borders, and marks that seem unrelated.
• Record where each mark appears; placement can be part of the evidence.
• Look for plating or filled terms as well as fineness numbers. Surface color alone does not establish a solid precious-metal alloy.

5. Decide which value question you need answered

Retail asking price, likely resale proceeds, insurance replacement value, and fair market value are different measures. An IRS publication illustrates the distinction in a tax context: fair market value concerns an informed, unpressured market exchange, while an insurance replacement figure is not the same measure.

• For curiosity or family cataloging, a documented photo screen may be enough to prioritize pieces.
• For selling, research recent comparable transactions and likely selling costs—not only retail listings.
• For insurance, ask the insurer what documentation and appraisal qualifications it accepts.
• For probate, tax, donation, divorce, or litigation, ask the responsible professional what valuation date, standard, and credentials are required.

6. Match the professional to the unresolved question

• A gemological laboratory can identify and grade eligible stones; its grading report is not a monetary appraisal.
• A qualified independent appraiser can address a defined value purpose and should disclose methods, assumptions, market, and effective date.
• A specialist dealer or auction house may be most relevant for maker attribution or a resale channel, but a purchase offer is not an independent appraisal.
• A conservator or experienced bench jeweler is the safer first stop when condition or repair risk is the immediate concern.
