Frankly speaking professionals looking at minerals by another eyes than even advanced collectors. As you may to see, it was clear to me 10 years ago, that these Alpine "gadolinites" are mostly hingganites without any analyses.
When you long time are interested in Gadolinite group minerals, you begin to distinguish them by colors quite easy. I am looking on them very intimately during past 40 years.
When I collected this sample
in 1990 in pegmatite overfilled with hingganites (which surrounds it even at these photos), it was quite clear for me, that this is gadolinite-(Y). But analyticaly confirmed this fact became only very recently
