Q: How should I care for this diamond and gold necklace?
A: To keep the diamonds sparkling and the gold polished, clean it occasionally with a solution of mild soap and lukewarm water, using a very soft brush to improved brilliance. Rinse well and dry with a soft microfibre cloth. Avoid harsh chemicals, chlorine, and ultrasonic cleaners. Store it flat or hanging to prevent the chain from tangling.
