Pyrite - Minas Victoria, Navajún, La Rioja, Spain
 
Sharp-edged, highly lustrous, golden-yellow pyrite crystals of up to 3.3 cm in length creating a highly aesthetic pyrite group on matrix. Such aesthetic specimens  with almost undamaged crystals are rarely offered, despite the large occurrence.
An eye-catcher and an excellent collector's item from this famous locality in Spain.
