Thanks. That was the thread a friend had told me about and I couldn't locate. Interesting that we both considered "Rhapsody."
I looked through the 1999 Chribska catalogue very carefully, especially the pictures on pp. 124, 143, and 147. (If I've missed the obvious one, please let me know.) I'm not yet convinced that my piece (or Emmi's for that matter) is pictured in there. Several reasons: first, the colours in mine are far more muted (they really do match the early "Rhapsody" pieces I have, see attachment); second, none of the pieces in the catalogue have a notch in the clear onto which the coloured lenses are applied (see attached photo); third, the shape isn't quite there.
I'm not saying it's not Chribska, early or late, just that I don't see it in the Chribska catalogue. In fact, whatever it is, I like it quite a lot, and for that reason I want to identify it.
