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

Tanzanite has cleavage and only moderate toughness, and can crack from knocks and temperature changes. GIA writes that ultrasonic and steam cleaning are never recommended.

Do this instead

  • Lukewarm soapy water and a soft brush
