Ooh, no, don't put anything with a "soft", porous stone in a dip or cleaner; use a silver cleaner on a cloth to clean the silver around the stone.

Thought their would be more a natural cleaner available,not enough decent jewellery to warrant a ultrasonic cleaner, whiskysheri website says that jade should not go in that type of cleaner
Use an old mascara brush dipped in the silver dip type cleaner and use it to clean the silver only rinse carefully and dry well then buff the silver bits with a soft cloth
