Oh, she doth teach the torches to burn bright! It seems she hangs upon the cheek of night Like a rich jewel in an Ethiopeβs ear,
From Romeo and Juliet.
Perhaps your memory combined this poem with the Bible account of the Ethiopian eunuch.
Even more Ike your memory is a modern English rendering:
Oh, she shows the torches how to burn bright! She stands out against the darkness like a jeweled earring hanging against the cheek of an African.
