Is it OK for your ultrasonic cleaner?

Opal

Yes
Check first
No

Avoid – opal can crack, and doublets are glued.

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 the only safe way is lukewarm soapy water, and that heat or temperature changes can make opal crack. Doublets and triplets are glued layers that should not be soaked.

Do this instead

  • Do not soak opal doublets
  • Avoid temperature changes
