Wavellite

A classic and particularly well-formed small cabinet specimen composed of hemispheres and near- spherical balls of Wavellite to 1.4 cm diameter from High Down quarry.  High Down is close to the small village of Filleigh in north Devon and is the type locality for Wavellite.  The Wavellite clusters have a satin-like lustre with a mustard to acidic yellow crystalline surface.  Incomplete Wavellite spheres reveal their white to colourless radial structure.  The Wavellite coats a characteristic dark grey Culm shale matrix and forms a really excellent specimen for this location.  It was collected in 1979 and is accompanied by labels from two well-known current collectors, one of whom collected it.
