Pyrite, feldspar var. Adular – Habach Valley, Pinzgau, Salzburg, Austria
 
 Sharp-edged lustrous pyrite cube in chlorite on matrix from the Habach valley overgrown with Adularia. The lustrous metallic sharp-edged cube pyrite stands in beautiful contrast to the transparent adularia. Very aesthetically build up specimen.
 The Adular shows strong fluorescence under UV light.
