All rhabdophane-(Nd) is microscopic to near microscopic patches, and then we have a 12 cm specimen with exceptional large spherules? I am of course not someone to challenge a prestigious museum, but still, I find it odd. Anyone have any information about this specimen?

The specimen I am questioning is rhabdophane-(Nd), not rhabdophane-(La).

Both the La and Nd minerals are in it.
