Yooperlite Sphere

Description

Yooperlite Sphere.
Yooperlite spheres from Michigan are glow in the dark rocks that are just mesmerizing. Who doesn't want to find natural stones that glow in dark?
Yooperlite is the name Rintamaki came up with, but the rocks are actually Syenite rocks that are rich in fluorescent Sodalite. ... The glowing rocks can be found mostly on Lake Superior between Whitefish Point an Grand Marais, and on the Keweenaw Peninsula.
