The Høydalen lithium pegmatite near Tørdal is known for a number of rare mineral species. Here we have a specimen with several black crystals of Gadolinite-(Y) that are embedded in white albite with some quartz and that are surrounded by a narrow, brown coloured rim of bastnäsite (?). The one somewhat larger crystal on the one side measures 1.1 cm. The other smaller ones on the other side of the specimen measure approx. 0.4 cm in average.

Collected in 1984.
