The dyes used in glow sticks usually exhibit fluorescence when exposed to ultraviolet radiation—even a spent glow stick may therefore shine under a black light. The light intensity is high immediately after activation, then exponentially decays.

Are Yooperlites rare?

Yooperlite is a unique formation of a fairly common element, fluorescing sodalite. What is uncommon is its presentation to the world at this time. There is always the hope of new discoveries.

Why do glow in the dark things stop glowing?

What stones glow in the dark?

Yooperlite is the name Rintamaki came up with, but the rocks are actually Syenite rocks that are rich in fluorescent Sodalite. The discovery was published in Mineral News in 2018.
