The Black Cytherea Which Is The White And Which Is The Black On A Clear Chess Set?

Which is the white and which is the black on a clear chess set? - the black cytherea

My boyf thinks that the parts are matte black and white stones are clear.
I think clearly the grinding parts look white, so white is ... and clearly (the dark especially when they played on a table)

And I teach science and clear (the absence of "light") is black, so I tried to win on a legal technicality, also ... lol

Please help us to decide:)
