Yooperlite (Fluorescent Sodalite Syenite)
Lapidary (Artisan/Custom) · Modern (Post-2017)
Identification summary
A Yooperlite marble is a lapidary sphere fashioned from a specific type of Syenite rock rich in fluorescent Sodalite. While the rock itself is ancient, its popularity as a 'Yooperlite' is a recent phenomenon in the rockhounding and marble collecting communities. These marbles appear as ordinary gray stones in daylight but glow with brilliant fire-like orange speckles under long-wave ultraviolet light (365nm).
