Be careful when cleaning precious stone jewelry with an ultrasonic cleaner. An ultrasonic cleaner can be dangerous if not used correctly. It may loosen stones from settings. Do not use with stones like emeralds and tanzanite that may fracture.

Heat can affect a piano’s sound. Do not put an antique or new piano in direct sunlight, or near a heat and air conditioning vent. An interior wall is best.
