Jools, $12

Diamonds may be a girl’s best friend, but your wallet knows that the young lady on your list will like these so much better. From left: peridot hearts on sterling-silver wires, emerald- quartz teardrops on 14-karat-gold-filled wires, and ruby-jade rondelles on silver. Or, hey, big spender: Why not give all three?
