Ultrasonic jewelry cleaner: when to use it and when not to

An ultrasonic cleaner uses vibrations in a liquid to loosen dirt from the smallest crevices. It is very effective, but not suitable for all jewelry.

Safe for #

Solid gold, silver and platinum, and untreated, unfractured diamonds, sapphires and rubies. It is very good for chains and settings with a lot of dirt.

Not safe for #

• Pearls, opals, turquoise, coral, amber and ivory.
• Emeralds and other stones treated with oil or resin.
• Glued stones, costume jewelry and plated pieces.
• Pieces with cracks or loose settings: the vibrations can loosen the stone.

How to use it #

Use lukewarm water with a little soap or the solution the device recommends. Leave the piece a few minutes (3-5 is enough in almost all cases), rinse and dry.
