Is it OK for your ultrasonic cleaner?

Diamond

Yes
Check first
No

The diamond handles ultrasonic cleaning – the setting and any treatments decide.

Updated from your answers.

A few questions to be sure

Is the stone fracture-filled, oiled or treated with resin/glass?
Does any stone move or rattle when you tap the piece lightly?
Are many small stones set close together (pavé, eternity)?

How to do it

Time
3 min
Water
Lukewarm, 30–40 °C

One drop of mild dish soap. Check the stones before and after.

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

Diamond is hard and withstands cavitation. GIA warns that ultrasound can loosen stones in their setting and wear the edges of stones set close together, and that fracture-filled diamonds should not be run.

Watch out for

  • Fracture-filled diamonds: avoid
  • Check that the prongs hold
  • Many small stones close together: let a jeweler look first
