context_page_description: Marcasite jewelry is jewelry made using cut & polished pieces of pyrite as gemstone, and not, as the name suggests, from marcasite.
  Both Pyrite & Marcasite are chemically Iron sulphide, but differ in their crystal structures giving them different physical properties - also known as polymorphism. Pyrite is more stable and less brittle than marcasite. Marcasite can also react with moisture to form sulphuric acid. These are the reasons why pyrite is used instead of real marcasite in "marcasite" jewellery.
  Marcasite jewellery is frequently made by setting small pieces of faceted pyrite into silver. Cheaper costume jewelry is made by gluing pieces of pyrite rather than setting. A similar-looking type of jewelry can be made from small pieces of cut steel. The cut & polished marcasite pieces reflect light at different angles from its different facets giving it a sparkle and making it attractive.
  Thailand is one of the large producers of modern marcasite jewellery in silver.
