It is a mineral produced throughout the world and is made of fluorine and calcium. This mineral has been modeled as a giant octahedron flying stone that appeared in "Castle in the Sky".

Unlike manufacturing products (fluorescent coatings), they are natural and may not be noticeable even in areas that are relatively fluorescent easily. Also, since it is a natural item, the color balance may vary.
