Record before you clean
Photograph the whole jewel front and back in neutral light, then record its clasp, hinge, setting, joins, missing elements, visible corrosion and movement. Include a consistent scale. Do not polish merely to improve the photograph: polishing is abrasive and can remove material and surface evidence.
Date every image and give it a stable file name. If the piece has several components, number them in a simple diagram. The museum parure shown here demonstrates why component-level records matter: a set is both one object and a system of individual parts.
Describe symptoms, not diagnoses
Write ‘the central stone moves when the ring is tilted’ rather than ‘the prong is broken’ unless a qualified professional confirms that diagnosis. Note when the change appeared and any impact, water, heat, chemical exposure or earlier documented repair.
Metal, solder, plating, enamel, adhesives, pearls and gemstones can respond differently to heat, solvents, pressure and cleaning. A photograph cannot establish identity or condition. Keep reports, invoices and prior repair records with the brief, but match them to the piece rather than accepting a loose document.
Define permission boundaries
Separate the minimum outcome from optional work: make the clasp safe; preserve original surfaces; do not polish, resize, replace stones or remove marks without a new written estimate and approval. Ask the jeweller to record any condition discovered after disassembly and return removed components when appropriate.
A conservator may prioritise reversibility and minimal intervention for a historic object, while a wearer may prioritise safe function. Neither priority should be assumed. The brief makes that choice visible before work starts.
Ask for the treatment record
The final record should identify who completed the work, the date, observations, materials added or removed, tests, photographs, care limits and any review date. Store it with the pre-treatment brief and receipt.
This is general collection-care education, not authentication, appraisal, legal advice or a remote condition assessment. Valuable, fragile, composite or historically significant jewellery should be examined by an appropriately qualified professional before cleaning, repair or alteration.
