The artefact corresponds to axes from the Late Neolithic (Eneolithic) Age and probably comes from the collection of the Wroc\u0142aw bishops originally deposited in the J\u00E1nsk\u00FD Vrch castle in Javorn\u00EDk. Although any localization is missing, its origin in Silesia is almost certain. Based on its appearance and magnetic susceptibil-ity measurement results, it was assumed the polished axe was made of nephrite. To prove this assumption the artefact was investigated using non-destructive x-ray diffraction (XRD) in a specially adapted apparatus. This type of determination was used in the Czech Republic for the first time. The analysis confirmed a monomineral composition represented by a monoclinic amphibole of the actinolite-tremolite group. This unique raw material naturally occurs in Jordan\u00F3w \u015Al\u0105ski - the only site in the whole of the eastern part of Central Europe."@en . "Kov\u00E1\u0159, Josef Jan" .
