Syenite rich in fluorescent sodalite, often referred to as “Yooperlites,” exhibits a distinctive glow under ultraviolet (UV) light. This unique optical property stems from the sodalite’s reaction to UV radiation, emitting a vibrant orange or yellow glow. While syenite itself is a relatively common igneous rock, the presence of fluorescent sodalite makes these particular specimens noteworthy and sought after by collectors and enthusiasts.
The perceived energetic qualities of these rocks have led to their increasing popularity within holistic practices. Though lacking scientific evidence, some individuals believe that holding or meditating with these stones can promote tranquility, enhance intuition, and facilitate spiritual exploration. Their visual appeal, combined with these attributed metaphysical properties, has contributed to their growing presence in alternative healing communities. Geologically, these rocks are found primarily in the Upper Peninsula of Michigan, hence the colloquial name referencing the region’s inhabitants.
