Legendary Crystal

The Cure Icon (キュアアイコン Kyua Aikon) are tiny pin-like objects used for the Cure's transformations. They were originally the Precure Crystals, kept by the Jewel Carriers of the Light Kingdom. They appear in Prism Pretty Cure! and without them the Pretty Cure can't transform. Starting from Episode 1, it was confirmed that there are five Cure Icon's, including Queen Juliet (Cure Light)

Appearance
The Cure Icon is pink, golden yellow, and it has a star and crescent moon with angel wings (most likely referenced to wishes and light). On the top of it is a golden crown and the edges has many angles on it. The icon also has a fragment of the Precure Crystal in a smaller size.
