It's a metaphor. Romeo is comparing Juliet to an earring which dangles against a person's cheek. The person's skin, like the night, is dark, and Juliet shines in the dark the way a jewelled earring might shine against the skin of a dark-skinned person. It is surely one of Shakespeare's most beautiful and evocative metaphors.
The whole statement "She doth hang upon the cheek of night like a fair jewel in an Ethiop's ear." is a complicated piece of figurative speech. The basic idea is a simile: the fair Juliet contrasts with the velvety darkness of the night in the same way that a jewel might contrast with the brown skin of an African. Because the comparison is explicit (it uses the word "like") in is a simile. But in the middle of it is the phrase "the cheek of night". Does night really have cheeks? No, of course not; people do. When things which are not people are given characteristics that people have, that is a personification. In addition, we are told that Juliet "hangs", but is she really dangling from a rope? No, this is also figurative, in order to give strength to the simile, and because in this case the comparison is not explicit, this is a metaphor.

simile i think
"She doth teach the torches to burn bright. It seems she hangs on the cheek of night like a rich jewel in an Ethiope's ear."
"Oh, she doth teach the torches to burn bright!" "She hangs upon the cheek of night like a rich jewel in an Ethiop's ear." He likes her, don't you think?
Hey, let us be a little friendly to those around us.
Slept peacefully. Cities don't sleep.
Idiom
A guy probably likes you if, when you are out together in a group, he hangs out with you for the whole night but then he never contacts you after that. Then when you see him out again he hangs out with you all night. It's clear from this that he likes you but not enough to actually make an effort to see you other than when you are out.
