Specimens of massive grey dolomite with a somewhat rhombic form, most likely a form of ankerite from Aust-Agder, Norway. Specimens are supplied in a white card tray with an information label, an interesting variation of dolomite and a must have for any mineral collection. Please note that some specimens may contain small amounts of actinolite and therefore all care must be taken to avoid breaking or disturbing the actinolite.
