The Jewel Thief is the 21st episode in Season 3 of H2O: Just Add Water.


Will presents Rikki with her own necklace made from the crystal they discovered in the Mako rock. The entire group make a startling discovery when Cleo notices an attraction between Rikki and Bella's crystals. Experimenting further the girls find when they touch them together an immense energy is released which creates a power surge in Cleo's home and disrupts an important program for Don on the TV! Will notes the girls' reactions to the surge and it appears they retain energy from the full moon. Inspired, Cleo successfully leads the girls to find another crystal in the wall of the Moon Pool. In an effort to regain Rikki's attention, Zane steals the new necklace. Rikki confronts Zane who's desperate to retain their relationship. When Rikki isn't interested and Zane becomes unreasonable, and threatens to reveal her secret, Cleo and Bella are forced to use the power of the crystals to recover Rikki's necklace. In the process, Sophie comes perilously close to recognizing the crystals' magic.


  • This is the last appearance of the lockets.
  • This is the second time that the three mermaids have matching necklaces. The first time, the original mermaids, had matching silver lockets. Emma, Rikki, and Cleo had those in the 1 and 2 seasons.
