Avoid – GIA advises against ultrasonic cleaning for star stones.

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

The star effect comes from fine needle-shaped inclusions, and the stones are often treated. GIA writes that star ruby and star sapphire should not be cleaned in an ultrasonic cleaner.

Do this instead

  • Lukewarm soapy water and a soft brush
