Is it OK for your ultrasonic cleaner?

Signet ring

Yes
Check first
No

A solid signet ring is fine – with a glued stone plate it is not.

Updated from your answers.

A few questions to be sure

Are the stones glued (no metal holding them)?
Is the piece solid, or plated/gilded?

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 signet ring in solid gold or silver handles ultrasonic cleaning, and the engraving comes out clean. Plates of onyx or lapis, on the other hand, are often glued.

Watch out for

  • Glued onyx or lapis: avoid
  • A lacquer-filled crest can come loose
