Amazing footage shows woman finding glowing “yooperlite” rocks for the first time 

This amazing footage shows a stunned woman finding glowing “yooperlite” rocks for the first time.  

The minerals, first discovered by Erik Rintamaki in June 2017, are said to be Sodalite gemstones that glow under a 365 nanometer UV light.

The video, taken by Erik last month, shows Shirley Klemmer finding the colourful shinning rocks on the coast of Lake Superior in Michigan, USA.  

Erik, 43, named the glowing rocks after residents of Michigan, who are often referred to as “yoopers.”  

The casino worker, who has been selling the rocks online, said: “I was leading a tour of people who wanted to find yooperlites and I asked Shirley if I could film her.  

“Once I posted it online, it just went berserk. Thousands of people were watching it.  

“When I first discovered these rocks, I was elated. You could probably hear my screaming from 20 miles away.  

“I didn’t even know what they were at first, so I just made up a name for them and went from there.  

“I’m just a regular everyday guy who collects rocks. Never in my wildest dreams did I think this many people would be interested in them.”
