Lollingita
Lollingita is a mineral with formula FeAs₂, in the Arseniuros group. This specimen comes from Huanggualiang Mine, Keshiketeng, Chifeng, Mongolia Interior, China.
Description
Silver Cabbage. Massive metallic matrix with mounds of calcite. Löllingite forms large lenticular crystals clustered like tightly packed cabbage leaves, with an intense silvery metallic lustre. These steely 'petals' envelop pink scalenohedral calcite, creating a stark contrast—harsh metal versus soft satin lustre.
