The image above shows an ultrasonic jewelry cleaner, it is one of the common devices used to clean gemstones and jewelry. When turned on, an ultrasonic jewelry cleaner generates high frequence ultrasonic waves. The jewelry or gems placed in the jewelry cleaner, gets cleaned as any dust or dirty clinging to the jewel or gemstone is 'loosended' by the ultrasonic waves. This seems like a fairly harmless process we however, need to understand what happens when emeralds are put in the ultrasonic cleaner.

It is not uncommon for some of these fissures to extend right up to the surface of the gemstone. Even if they are below the surface, they could be just too near to the surface. Another thing about emeralds is that, they are almost always (98% of the time), treated with natural oils. The natural oils seep into the fissures and softens their visibility. This is responsible for imporving the beauty and lustre of the gemstone. Let us know analyze these 2 facts and relate it to the cleaning of emerald gems in ultrasonic cleaners.
When the emerald gemstone is put into the ultrasonic jewelry cleaner and the device turned on, the ultrasonic waves pass through the gem. They could expand the fissures and cracks in the emerald, this effect could be so severe that the gemstone could break into pieces. The oils in the emerald put there by the enhancing treatment could also be pushed out of the fissures and ooze out of the gemstone. This is surely not good for the emerald and will negatively affect it's beauty. This is why emeralds should not be cleaned in ultrasonic cleaners.
