Zircons from Seiland is by far the world top for their deep red color with transparent and gemmy areas. The zircon site has been heavily mined in the '80s and '90s, and nowadays it is extremely difficult to collect decent specimens if not spending several days with heavy tools for digging. It is also at the border to the national park, so you would have problems for granting rights to do mining. The specimen for sale is from the old days when it was still easy to find zircons.
