Wavellite - Mauldin, Arkansas, USA
Small piece composed of two spheres of bright wavellite: the first one, incomplete, shows the typical fibroradial internal structure. The second one, complete, is half green and half grey, which we suppose to be a pseudomorphosis of wavellite into crandallite (source: https://www.mindat.org/gallery.php?loc=11467&min=1147).
