[Rockhounds] Swedish Mineral Sites

[Axel Emmermann]

Hi Brother Don, Jack,

I recently aqcuired a specimen from the Stakholmen quartz quarry, Hassela,
Nordanstig, Hälsingland, Sweden.
It's labelled prismatine but there is some very fluorescent phlogopiet on
it.
Where the prismatine is in contact with the gangue, it too becomes
fluorescent but only under MW-UV. The phlogopiet does it in SW and MW.

The  prismatine cannot be recovered in good crystals since it breaks with
the quartz gangue.

Cheers
