Wood Wood is a natural material that can be used to create fashion jewelry. It is usually finished off with a coat of resin to make it more tough and long-lasting. It gives jewelry a more primal and natural feel.
Marcasite The mineral marcasite, sometimes called white iron pyrite, is iron sulfide (FeS2) with orthorhombic crystal structure. On fresh surfaces it is pale yellow to almost white and has a bright metallic luster. It tarnishes to a yellowish or brownish color and gives a black streak. It is a brittle material that cannot be scratched with a knife. It typically forms under low-temperature highly acidic conditions.
