Yooperlite Rocks
Yooperlite is one of the most interesting rocks. It’s known for a beautiful, spotted fluorescence that displays in awesome ways with UV light, but few people are quite sure of what it really is.
Technically, yooperlites are a form of sodalite-rich syenite. Sodalite is mainly known for its royal blue color and mottling with white limestone, similar to lapis, but the mineral glows under UV light.
