Care begins before the polish comes out. A useful routine protects the object’s structure, surface and history, then asks whether any treatment is needed. The right decision for a plain modern chain may be wrong for a gilded brooch or a locket holding a photograph.
Start with the parts that do the work
Inspect the places that do work: links, joins, hinges, catches and settings. Note distortion, loose components, worn decoration and visible repairs before wearing or cleaning a new acquisition. Ask a qualified jeweler to assess doubtful fastenings or settings rather than testing them by force.
Support the whole piece on a clean, padded surface while you look. Photograph the front, reverse, fastenings and existing damage. Compare both earrings or cufflinks, including their backs. Record a gap, bent wire or mismatched fitting as an observation; do not turn it into a repair diagnosis from appearance alone. A reluctant clasp is a reason to stop, not pull harder.
Decide what surface you want to preserve
Silver tarnish develops through reactions with sulfur-containing gases. Removing it by polishing also removes some silver, so constant brightening is not a harmless routine. Plating and gilding need particular caution. Identify nonmetal components and surface finishes before choosing a cleaning method; immersion is not suitable for every construction. When materials or repairs are uncertain, seek advice before treatment.
Separate dirt from tarnish and deliberate dark detail. Before asking for a bright finish, consider whether cleaning would remove the contrast that makes engraving or relief readable. A documented, stable surface need not be polished simply because the piece is going into storage.
Treat the most vulnerable part as part of the jewel
Make a materials list before choosing water, chemicals or an abrasive cloth: metal, plating, gilding, stones, enamel, adhesive, cord and any interior contents. A 925 mark does not describe all of them. Hollow components and inaccessible joins can retain liquid, while paper or textiles inside a locket need a different approach from its metal shell.
If construction or treatment history is unknown, postpone immersion and polishing. Do not scratch through a finish to identify it or force a setting open. Our water-care guide explains the separate questions raised by washing, swimming, hollow construction and stone-set pieces.
Preventive storage reduces the need for repeated treatment. Keep pieces supported and separated so heavy links, pin tips and hard stone edges cannot rub against neighbouring surfaces. Let a flexible chain rest without knots and support a rigid collar in its existing shape rather than flattening it.
CCI recommends individual polyethylene bags and sulfur-free, unbuffered archival tissue for suitable silver objects. Keep stored pieces clean and dry, and choose enclosure materials deliberately. Avoid unknown foam, rubber bands and decorative fabrics whose dyes or sulfur-containing materials may affect the metal. Mixed-material jewelry may need a different storage environment; ask a conservator before adding a drying agent or sealing a vulnerable composite piece.
For a wearable piece, ask a qualified jeweler to assess fastening security, worn joins and stone retention. For an archaeological object, fragile historic finish or culturally significant piece, seek a conservator’s advice before restoration. Explain whether your priority is safe wear, preserving original evidence or display.
Request a description of the proposed intervention: which parts will be replaced, whether heat or chemicals are involved, and what finish may change. Keep before-and-after photographs and a repair record with the object. If no safe treatment is established, careful storage and not wearing the piece are valid outcomes.
