A gorgeous, very colourful specimen of Willemite and associated Mimetite. The Willemite takes two forms - dome like aggregates of translucent celestial blue pseudo-prismatic adamantine crystals, to 12mm across - and gemmy, lime green adamantine prismatic individual crystals, to 2mm, in many places crystallising on top of the blue Willemite. The Mimetite crystallises as yellow elongate lustrous aggregates or as acicular sprays of crystals. The brown mineral is Goethite. A richly mineralised piece and displays very well.
