The Legendary Pieces (伝説 の 小品 Densetsu no Shōhin) are special pieces that can be used to help the Cures from Jewel Star Pretty Cure to find the three Legendary Items. The Legendary Pieces are stored in the Golden Case.
Legendary Pieces are shaped as stars and come in any kind of colour. All Legendary Pieces have little golden hearts on them.
When set on one of the girl's Shiny Bracelet, each Legendary Piece can help them navigate the Legendary Items. They also have the power to bring no life or light to all worlds if Dark Star got their hands on them.
- The Legendary Pieces have a similar function to the Cure Decors from Smile Pretty Cure!
