Description

Romanechite is a very rare barium-rich manganese oxide, and usually you don´t get a Romanechite specimen - most times it is just an addition on other minerals as tiny crystals for the microscope or the loup or as ugly layer. The only other relevant small Romanechite discoveries were in Spain and Germany, so this is really a very rare mineral and it comes only from a fist full of localities. This material was discovered in 2020 in Királyszentistván, discovered by a local field-collector - there was a very interesting article about the discovery in Lapis magazine. 

Romanechite developed a sculptural assemble, vey aesthetic and tri-dimensional! The contrast to intense yellow-brown Goethite gives a great visual impact to the piece, the white material at the base is etched Dolomite. The piece is complete all around, undamaged and looks great in really each position."
