Yooperlite raw stones are a type of syenite rock containing fluorescent sodalite, found along the shores of Lake Superior. Under normal light, each piece appears as a dark grey to charcoal stone with a rough, natural surface. Under UV (ultraviolet) light, the stones reveal vivid yellow to orange-yellow fluorescent patches across the surface, creating a dramatic glowing effect. The size, shape, and distribution of the fluorescent areas vary naturally from piece to piece.
These fully opaque, rough stones make a unique, conversation-starting addition to any crystal collection, home décor, or display — especially striking when viewed under UV light.
