About this specimen

Yunnan iron concretion at 9.5 cm and 796 g; a cabinet sphere formed by nature. Keep dry.

Iron concretions are rounded iron-oxide nodules that grew around a core in sediment; Yunnan pieces are collected for their sculptural, sometimes pyrite-bearing forms.

Yunnan is China's most mineralogically diverse province, source of the pyromorphite, azurite and blue aragonite that have become collector favourites.

Dimensions place it in the cabinet range, 9.5 × 8.8 × 7 cm (3.74 × 3.46 × 2.76 in) and 796 g (28.1 oz). Condition is otherwise as photographed.

Specimens are photographed and catalogued one at a time before they reach this page.
