Zircons from Seiland are by far the world greatest, because of their deep red color with transparent and gemmy areas. The zircon site has been heavily mined in the 80's and 90's, and nowadays it is extremely difficult to collect decent specimens without spending several days with heavy tools for collecting. It is also at the border to the Seiland National Park, so you would have problems for granting rights to do mining.The specimen for sale is from the the 1990's when it was still easy to find zircons, and before the National Park was established (in 2006).
