I have not myself seen such a superb specimen of marcasite from this important, ancient gold mining district. Although known for 2000 years, we only know of specimens from a small period of time in the 1700s to 1800s, mainly. So much was lost. And of what survives, it is no wonder that people saved golds over marcasite. This specimen is a rarity. It has a rich metallic-shimmering look to it, quite different and more elegant than marcasite from France or Trepca to my eye. Ex. Harold Urish Collection.
