It is natural to want jewelry to look its best before an evaluation. But when precious-metal content is the main consideration, aggressive cleaning rarely adds value—and can sometimes damage the piece.
A gentle wipe is enough
You can remove loose dust or surface dirt with a soft, dry cloth. If a piece is tangled, do not force it apart. Bring it in carefully packaged so it does not become more damaged on the way.
The buyer is interested in what the item is made of, how much it weighs and whether it has value beyond the metal. Shine alone does not answer those questions.
Why harsh cleaning can backfire
Strong chemicals can discolor certain alloys, loosen glued stones or damage porous gems. Abrasive materials can scratch metal and remove finishes. On antique or collectible pieces, over-polishing can also remove patina that helps tell the item’s story.
- Avoid bleach and household cleaners
- Do not use toothpaste or abrasive powders
- Do not soak jewelry with unknown stones
- Do not remove stones or cut apart settings
Bring it as you found it
If a piece has spent years in a jewelry box, that is perfectly fine. An experienced buyer can work with tarnish, ordinary wear and broken components. Your time is better spent gathering the complete group and any documentation you already have.
Every item is different. The most reliable way to understand what you have is through an in-person evaluation.
