BestBuilt Ultrasonic Cleaners utilize industrial transducers to create powerful 40KHz ultrasonic wavelengths: short enough to clean the finest details of your jewelry and powerful enough to remove caked-on dirt as well as rouge and other compounds. Industrial strength transducers are more powerful and more durable than the standard wafer transducers found in most jewelry ultrasonics. Made in South Korea.

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.
