Is it OK for your ultrasonic cleaner?

Pearl necklace

Yes
Check first
No

Never ultrasonic – both the pearls and the silk thread are damaged.

Updated from your answers.

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

GIA writes that pearls should never be cleaned with ultrasound or steam. AGS also warns that the thread can stretch and break when it gets wet.

Do this instead

  • Wipe with a soft, slightly damp cloth after wearing
  • Have the pearls restrung by a jeweler when needed
