Turquoise settings in jewelry range from small pieces in rings to large stones in pendants. The stone, often associated with Native American jewelry, is usually set in sterling silver. Although turquoise is heavy and sturdy, it is susceptible to damage from soap and other cleaning products. Cleaning your turquoise jewelry with water once a week keeps it looking its best without subjecting it to harmful substances. Properly maintained, turquoise-and-silver jewelry regularly lasts for years.
Dip a child's soft toothbrush in water and shake it to keep it from dripping. The brush should be damp, but not wet.
Gently brush the turquoise stones, avoiding the silver as much as possible.
Wipe the stone dry with a clean jewelry-polishing cloth.
Polish the silver with the cloth, rubbing gently back and forth until the jewelry is shiny.
