Guidelines for Gemstone Cleaning

Using steam or an ultrasonic cleaner depends primarily on the gemstone being cleaned. Generally speaking, organic materials (bone, coral, pearls, etc.) cannot take ultrasonic cleaning. (That also means you should not immerse your hands or fingers in an ultrasonic cleaner while it's running.) You may want to print out the chart below and hang it near your cleaning area for instant reference.

Any stone with a crack in it should not be ultrasonically cleaned.
