This cabinet piece consists of a conglomerate base rock that is partly coated with a thin Carnotite crust. The crust shows no evidence of crystal form whatsoever and has a deep yellow color and a matte luster. There are patches of a paler yellow, crumbly material in the base rock- I cannot be sure if this is more carnotite or perhaps a different, related uranium mineral.
