A fantastic example of an interpenetrating twinned Fluorite from the Heights Mine, Weardale. Probably one of the oldest locations for green Fluorite in the area. This fine specimen shows modified cubic crystals to 4.3cm on edge, which also show oscillatory growth. The specimen is lustrous with deep green colour. A large crystal from this mine.
