Our pieces of jewelry, which are made of copper, are multiply 18 carat gold plated. The "tarnishing" and discoloration of the jewelry is unimaginable due to the high-quality processing of the jewelry. Despite this, there is nothing to be said against regular care of the jewelry to maintain its shine. These pieces of jewelery can be gently cleaned with a soft cloth or cleaned in lukewarm water using a soft toothbrush and mild detergent. However, the cleaning must not be too aggressive.
