Most of the jewelry pieces are created with natural raw copper and will need minor maintenance to keep them looking beautiful. We recommend that on occasion or if you start to notice discoloring use a silver polish cloth and wipe clean. If you need a deeper cleaning use 0000 grit steel wool and lightly rub over the copper areas being careful not to rub any stone, rinse with lukewarm water and pat dry. Brightly colored copper has been treated with a sealer and will not require any special care.
