The jewels of our father, with wash’d eyes
Cordelia leaves you. I know you what you are,
And like a sister am most loath to call
Your faults as they are named.

– William Shakespeare

King Lear, Act 1, Scene 1. Bidding farewell to her sisters Regana and Goneril, Cordelia refers to them as "The jewels of our father." Ordinarily this metaphor would be a flattering term, but here it is used ironically to express contempt. While Cordelia also says that as a sister she won’t name their faults, she makes clear that is well aware of their true intentions and game they are playing in kissing up to Lear.
