- Gem dealer Erik Rintamaki discovered Yooperlite rocks on the beaches of Lake Superior that seemed to glow as though they were molten. Researchers from Michigan Tech University and the University of Saskatchewan managed to figure out why they fluoresce: they contain syenite clasts wich containing fluorescent sodalite, an intrusive magmatic rock, which glows when exposed to UV light.
- Fluorescent sodalite is known as hackmanite and has tenebrescence properties which simply means it has the ability to change color under various conditions. When viewed under ultraviolet light, it seems to glow, usually an orange or orange-red color. When the ultraviolet is removed, it fades back to its original color and vice versa.
- Testing completed at Michigan Technological University confirmed that yooperlites contained sodium, alumina, silicon, chlorine and oxygen but not structural sulfur. Yooperlites have likely been in Michigan for centuries, left behind by the glaciers and rounded by the wave action of Lake Superior.
