Panton Fun Chandelier ID  

Seems to me that the Panton lights are always strung with round-link chains with one hole drilled into the shell disk. Also, the styles with multiple sections don't have shells between the sections as yours does. Are you aware that there are tons of hanging light fixtures made of capiz shell disks?

I have never been a fan of this light for the simple reason that it is a giant dust catcher. Just thinking about cleaning it gives me a migraine.

Pantonworld has an extensive collection of the works of Verner Panton, you shouild do your research from there.
The lamp you showed is not Panton but most likely the look alikes that are still being made in the Phillippines as tourist souvenirs made of a common flat shell oyster called 'kapis' (or Capiz) found in the South China Sea traditionally used as translucent window panes in lieu of glass in the Phillippines.
Pay accordingly.
Also cleaning these is as easy as submerging the shells (without the electrical wires) into soapy water for a while loosening the dust, rinse and air dry.
