Description

This is a lot of 7 Yooperlite stones found on Lake Superior in the Upper Peninsula of Michigan. The combined weight of the 7 stones together is 7.62 ounces. Please refer to the pictures for the size with the ruler.
The first 4 pictures are the front and back of the stones. The first 2 pictures are the same side of the stones, with the light and without the light. The next 2 pictures are the other side of the stones.
I used a 365 nm wavelength UV flashlight for these pictures. I do sell this exact UV flashlight I used for these pictures in my ebay store if you need one.
