The Moonstone is a spherical blue gem from the movie continuity that looks like the full moon. Every eight years it is placed into a ceremonial scepter and used to transmute the light of the blue moon into blue pixie dust, which is used to restore the strength of the Pixie Dust Tree. Fairy Mary described it as "ridiculously fragile," and Tinker Bell accidentally broke it. However, its shards were still usable and Tinker Bell was able to arrange them to maximize its potential output.[1]

In The Hidden World of Fairies, Wendy Darling states that Queen Clarion has a crown set with a moonstone.
