Gold, just gold - as it is an element (symbol Au). Most gold jewelry is really made of an alloy of gold, which means it contains gold and also other metals which lower the cost and provide increased durability, decreased malleability, etc. Atoms of gold are made of protons, neutrons, and electrons... just like atoms of any other element.
