Zircons in Biotite
Location: Store Kufjorden, Seiland, Finnmark, Norway
Size: 58x55x40 mm (205 gr.)
On this specimen there is an almost undamaged zircon crystal on 16 mm. There is only a minor mark after Biotite, and some tiny damage on the top.
On the underside / back there is a large crystal (16 mm wide), seen on the last 2 pictures. In the pictures it may look damaged, but for the most part it is only deformed with Nepheline / Biotite grown into this crystal. Otherwise there are about 10 smaller zircon crystals 4-5 mm.
Zircons from Seiland
Zircons from Seiland are by far the world's greatest because of their deep orange/red color with transparent and gemmy areas. The zircons are yellow SW and LW UV fluorescence.
The zircon site has been heavily mined in the '80s and '90s, and nowadays it is extremely difficult to collect decent specimens without spending several days with heavy tools for mining. It is also at the border of the Seiland National Park, so you would have problems with granting rights to do mining. The specimen for sale is from the 1990s when it was still easy to find zircons, and before the National Park was established (in 2006).
The specimen was found late in the late 1990s by my father, Gunnar Mathisen, who had exploration rights back then.
