How to check a piece before ultrasonic cleaning
Identify every material
Confirm the metal, stones, coatings, adhesives, and any enamel or inlay.
Check treatments and condition
Look for a grading report, seller disclosure, loose settings, cracks, repairs, or worn plating.
Follow the strictest guidance
If any part is unsafe or uncertain, choose hand cleaning or a professional jeweler.
Ultrasonic jewelry cleaner FAQ
What jewelry should not go in an ultrasonic cleaner?
Keep pearls, opals, emeralds, turquoise, amber, coral, glued pieces, plated jewelry, watches, enamel, damaged settings, and unknown stones or treatments out of ultrasonic cleaners.
Can you put gold in an ultrasonic jewelry cleaner?
Solid gold is generally compatible when it has no fragile stones, plating, glue, loose settings, cracks, or restricted treatments. Check every component, not just the gold.
Are diamonds safe in an ultrasonic cleaner?
Untreated, secure, undamaged diamonds are usually safe. Do not use an ultrasonic cleaner for fracture-filled diamonds, loose settings, heavily included stones, or chipped diamonds.
Can an ultrasonic cleaner loosen gemstones?
Yes. Vibration can expose a worn prong, weak solder joint, hidden crack, or loose stone. Inspect the piece before and after cleaning, and stop if anything moves or rattles.
What is a safer alternative to ultrasonic jewelry cleaning?
Use a soft lint-free cloth and a hand-cleaning method approved for the exact material. A qualified jeweler is the safest choice for porous gems, treatments, antiques, damage, or valuable pieces.
