A little introduction to this occurrence of precious opal is needed. Precious opal from this occurrence in Europe is most likely the oldest known source for the production of the gem. Different records in literature can often detail geographically different names of localities with different emphasis. An attempt will be made to elucidate these differences so that it will become apparent that the records are of the same opal fields in each case. It is also interesting to note that various places named which are associated with European opal have ben “anglicised, or if I may “Americalified”. Peter Semrád allays all of these issues in his book: “The story of European Precious opal from Dubnik” 2011. ISBN: 978-80-7296-079-8.
