"This plate is pretty, but that one is not."

Translation: Questo piatto è carino, ma quello non lo è.

I was surprised that my sentence went wrong: 'Il piatto è bello, ma quello no'.
Is it wrong ?

Well, you missed a translation for "questo" (this).

[J.Franchomme]

True. Thank you.
But do you think the sentence 'Questo piatto è bello, ma quello no' could be considered as correct?

[f.formica]

I think it should be acceptable, it's a common way to say it in Italian.
