Yooperlite is a new crystal that was recently discovered in lake Superior near Michigan, USA in 2017. At first glance, it looks like a regular stone, but when you put in under UV light it glows like it was on fire! Yooperlite rocks are actually Syenite rocks that are rich in fluorescent Sodalite. It is the fluorescent sodalite that gives this crystal that incredible orange and yellow glow under a UV light.
