Yooperlite is the trade name for syenite rich in fluorescent sodalite, discovered along the shores of Lake Superior. Under normal lighting, these stones display attractive gray, cream, and black mineral textures. Under longwave ultraviolet (365 nm) light, the sodalite fluoresces a brilliant orange-yellow, revealing hidden patterns that are invisible in daylight.

This polished Yooperlite sphere features a classic mottled gray matrix with contrasting black mineral inclusions and subtle crystalline textures throughout. When illuminated with a 365 nm UV light, dozens of vibrant fluorescent sodalite patches ignite across the surface, creating a dramatic constellation-like display. The contrast between its understated daytime appearance and its brilliant fluorescence makes each viewing experience uniquely engaging.

Selected for its strong UV response and attractive natural patterning, this specimen is equally at home in a mineral collection, cabinet of curiosities, or interactive natural history display.
