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.

> [!NOTE]
> If you have doubts about a piece, ask a jeweler before using the device.
