A few questions to be sure

Does any stone move or rattle when you tap the piece lightly?
Are there stones in the piece?

How to do it

Time
3 min
Water
Lukewarm, 30–40 °C

One or two drops of mild, unscented dish soap. Rinse in clean water and dry with the microfiber cloth.

With these answers we do not recommend the ultrasonic cleaner, so there is no how-to.

Pick your cleaner to see if it fits, which setting to use and what its manual says.

Why

A prong setting leaves the stone open so that the ultrasound reaches underneath it. GIA points out that a loose stone can wear through a prong, and that the vibrations can loosen stones in poor settings.

Watch out for

  • Worn or bent prongs: have it looked at first
  • If the ring catches on your sweater, a prong is often loose
