Rainbow Gem

The Rainbow Gems (レインボージェム Reinbō Jemu) are magical stones in Rainbow Pretty Cure☆Destinies Unfold. There are forty Rainbow Gems in total. When all Rainbow Gems are collected, the Cures can seal Diabolos, which is why Noir is searching for them in order to destroy them.

Appearance
All the Rainbow Gems are tear-shaped, and have a silver rim. The main jewels are also the theme colours of the finder. On the back of each Rainbow Gem, the Rainbow Pretty Cure insignia can be seen.

Powers
When all forty Rainbow Gems are collected, the evil sorcerer Diabolos will be sealed. No other powers of the Rainbow Gems have been discovered.
