Can you clean jewelry in an ultrasonic cleaner?

Yes – but not for all materials. Ultrasonic cleaners are very effective for gold jewelry without sensitive stones. For jewelry with pearls, opals, emeralds, turquoise, or glued-in stones, ultrasonic cleaning is forbidden.

Suitable for Ultrasonic Cleaning

• Gold necklaces and gold bracelets without stones
• Gold rings without stones or with diamonds in prong settings
• Platinum jewelry without sensitive stones

Never in the Ultrasonic Cleaner

• Pearls: Vibrations destroy the nacre layers
• Opals: Can crack due to water ingress
• Emeralds: Oiled stone loses its impregnation oil
• Glued-in stones: Adhesive dissolves
• Turquoise, moonstone, labradorite: Sensitive surfaces
