Discovered in 2017 by Erik Rintamaki, who gave them their regional northern Michigan name. They’re made up of mostly syenite rock, which is similar to granite, which means the rock looks like any other dark stones or typical gray rock, but there’s a twist. Yooperlites are rich with fluorescent sodalite, which glows a vibrant orange or yellow under Ultraviolet Light. It is the stone of truth by allowing one to recognize and express their feelings objectively. It releases anger and negative thoughts plus helps fight your fears and phobias. It creates a clear and perceptive mind, to enhance your ability to find inner peace.
