I have visited my friend and mineral collector Ivo Halicek few days ago. The primary reason was to discuss his website development but I managed to do also some photos of his awesome minerals. I have focused on pyrite because I needed photos for the pyrite article.
Pyrite with sphalerite and quartz from abandoned mines in Banska Stiavnica, Slovakia. Now considered a classic and very expensive material. Size 6.5×4.5 cm.
Nice texture of polished slab of malachite from Katanga, Democratic republic of Congo. Aproximately 10 cm wide.
Nice pentagon dodecahedron of pyrite from Rio Marina, Elba island, Italy. This classic piece has 6×6 cm.
