In jewellery, iron pyrite used as gem is improperly termed "marcasite"
Origin of name from Arabic or Moorish for pyrite. Pyrite and Marcasite
share the same exact chemical make up; however they both differ in
their interior structure." Marcasite" is frequently found in
inexpensive silver jewellery and watches. It was fashionable and popular
in Victorian and other times where it was often used to imitate
diamonds. In better quality jewellery it is hand-set with grains or
beads of metal from the setting being pushed over the edges of the
stones." Marcasite" occurs world-wide and is easily found in the chalk
near Dover, Folkestone, and the French side of the English Channel.
