Bright yellow-orange pseudomorphoses of "gummite" after cm-size cubo-octahedrons of broggerite. Composition of this gummite is very interesting - central orange oxide core consist of translucent thorian curite, it is surrounded by yellow silicate rim, composed from bright yellow casolite (more former/inner) and pale yellow soddyite (more later/outer). Pegmatite matrix especially micas are penetrated by light-yellow films of later earthy uranophane. Specimen size is 5x4 cm and its total radioactivity is ~690 μR/h. FOV is ~1.5x1.5 cm.
