Those happy smilets,
That play’d on her ripe lip, seem’d not to know
What guests were in her eyes; which parted thence,
As pearls from diamonds dropp’d.

– William Shakespeare

King Lear, Act 4, Scene 3. The Gentleman tries to describe Cordelia’s reaction to the news about her father’s ordeal, as she smiles and sheds tears on receiving Kent’s letters. Two beautiful metaphors and a simile are used to paint the picture – "play’d" and "guests" and "As pearls from diamonds."
