Marcasite, a bronze-yellow mineral often known as fool's gold, displays a sparkle and shimmer similar to diamonds -- but at more affordable prices. Ancient civilizations of China, Egypt, Greece and South America turned the versatile mineral into stones for ornaments and jewelry. Today, the marcasite stones are used to create elegant bracelets, necklaces, rings and earrings. Although marcasite jewelry requires little care, occasional cleaning helps remove tarnish and restore luster and shimmer.
Wipe marcasite jewelry gently with a soft, damp cloth. Never use hot water and avoid soaps, cleaners, silver dips or other chemicals. Although soap and other cleaners won't damage the marcasite, they may dissolve the glue that holds the setting in place.
Dry the jewelry carefully with a soft, absorbent cloth or jeweler's cloth.
Lay the jewelry on an absorbent towel and allow it to air-dry overnight, or until you're sure the piece is completely dry.
