A stone that temporarily radiates light when it comes into contact with air.
It is prized as a one-of-a-kind jewel, but with no use in crafting, it is mostly employed simply as a guidepost.
Can be dropped as a marker.
The stones are presented in eight different colors; red, yellow, pink, purple, green, blue, turquoise and white.
The color when dropped is completely at random.
Lasts until; profile load, game quit, world stage load.
You can place up to 16 stones at the same time, after which time previous stones will begin disappearing.
