Is it OK for your ultrasonic cleaner?

Zircon (natural stone)

Yes
Check first
No

Avoid – natural zircon is brittle and heat-sensitive. Not the same thing as CZ.

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 ultrasonic and steam cleaning are not recommended for zircon. The stone is brittle, and heat can change the colour of heat-treated stones.

Do this instead

  • Cubic zirconia (CZ) is a different material – see CZ
