Hello, and thank you for reading!

Currently I am PhD. student of mineralogy on the Comenius University in the capital of Slovak Republic, Bratislava. I collect only minerals from the territory of Slovak Republic with the emphasis on fine classics and some species (like various supergene minerals, sulfosalts atc.) or specific localities. Here I present mostly pictures of specimens from my species collection.
