The Water Stars Catcher is an item capable of capturing the Water Stars.
It is a red, kite-shaped jewel encased in a silver setting that has four distinct hoops. The setting is joint at a circular shape on the top left corner and it ends in a circular shape at the bottom of the jewel. Part of the setting wraps around the tip of the jewel.
In "Wizard's Anger," Valtor uses it to capture the Water Stars and uses their power to attack the Winx. After unleashing the spells Valtor captured in the Agador Box, Valtor releases the item from his grasp and it is caught by Stella.
- Its appearance is similar to that of the Eye of the Ancient Ancestress.
- In the flashbacks in The Red Tower while Tecna is telling the Winx about the history of the Water Stars, the Wizards who caught the Water Stars are seen using a purple stone or crystal to catch them instead of the Water Stars Catcher.
