RE: suum cuique pulchrum est

I can find reference to suum cuique in Cicero as per the post above (from Wikipedia) in De Natura Deorum, III, 38.

However, I cannot find any evidence of the longer expression suum cuique pulchrum est (which has a different meaning to the sense found in De Natura Deorum) being reliably associated with Cicero (or anyone else for that matter).

Thoughts or guidance on this welcome! :-)
