Gadolinite
Ytterby, Vaxholm, Sweden
FoV: 5 x 3 cm
Not a too good piece, but gadolinite from this historical Swedish quarry was the most important mineral for the discovery of most of the 10 different rare earth elements - four of which have names derived directly from the place itself: Yttrium, Terbium, Erbium, Ytterbium
