Description

A very interesting gold piece from Norway. It is accompanied by cubic pyrite and a metallic gray leafy mineral, which the previous owner had interpreted as sylvanite - see label.
Various researches, especially on mindat have shown that it is most likely Nagyágite. Especially since sylvanite is not listed there under this locality.
However, only an analysis can provide final clarity on this issue..
