Start with your jeweler’s advice
Care depends on the complete jewel, including its metal, settings and any other gems. Ask for cleaning instructions suited to your particular piece. Do not assume a method that suits a loose diamond is safe for every antique or mixed-gem jewel.
Make room for a routine
Take jewelry off for activities where it could be knocked, caught or exposed to chemicals. Store individual pieces separately to reduce contact between them. Before wearing a ring, notice whether the stone or setting feels loose and have concerns checked promptly.
Be careful with cleaning
Avoid aggressive home experiments or cleaning machinery without professional advice. If your jeweler recommends gentle hand cleaning, follow that advice and work in a bowl away from an open drain. Stop if the piece appears damaged.
Document what you own
Photographs, invoices, reports and maintenance records help you keep track of a collection. Ask an insurer what documentation and valuation it requires rather than treating a purchase receipt or auction headline as a complete insurance plan.
