Yooperlite bracelets 
Yooperlite is a Michigan rock that glows with a black light 
What are Yooperlites. These seemingly normal, gray rocks are rich with fluorescent sodalite and glow a vibrant orange and yellow under a UV light. If you've enjoyed looking for rocks during the day, wait until you try finding them at night!
