What gemstones can I put in the ultrasonic cleaner?

Ultrasonic cleaners are often used to clean jewellery and gemstones, as they can remove more effectively dirt, debris, and oils from the surface of your jewels compared to alternative, perfectly acceptable jewellery cleaning approaches.  

However, not all gemstones can be safely cleaned in an ultrasonic cleaner. Here are some guidelines for using ultrasonic cleaners with gemstones: 

Ultrasonic cleaners are safe for gemstones like diamonds, sapphires, and rubies, but be cautious with softer and organic stones such as pearls, opals and especially, emeralds. Some of these gemstones may have oils or treatments applied to enhance their appearance, which can be removed by the ultrasonic cleaning process.  

Pay attention to the settings and mountings of your jewellery. Before putting your jewellery in the ultrasonic cleanser, check if the gemstones are securely set to avoid damage during the cleaning.
