Allusion: Diamonds were not a girl's best friend, she realized, as the attendant pointed at the astronomical number attached to the ring.
Simile: Her eyes were clear and blue like sapphires.
Metaphor: A steady trickle of ruby droplets ran from the corner of his mouth, interrupted by a wet cough and the subsequent heaving of his chest.
