Moonstone

Moonstone is a blue jewel with a form of sphere which is featured in the movie, Tinker Bell and the Lost Treasure.

History
The Moonstone was always placed in the Scepter, for each eight years on full blue moon so Pixie Hollow would blue Pixie Dust, that was used to help the Pixie Hollow Tree. Tinkerbell then took it home as she then broke it. In despair Tinkerbell went to an island due north of Neverland, to search for the Mirror of Incanta, which granted three wishes but two were spended as then only one wish was left.

Tinkerbell to restore the gem tried to wish for the Moonstone to get back to its circular shape but accidentally she wished for Blaze to be quiet. After no luck her only hope was to make its shape different, with Terence's help they made a new shape.

By using all the pieces, along with a diamond Tinkerbell had found, they designed the scepter so that when the blue moon shined through the diamond, it refracted the light into the moonstone pieces, maximizing the effect, and creating more blue pixie dust than ever had been seen at any prior Autumn Revelries.
