Localities

At the type locality, Kalugeri Hill, Babuna Valley, Jakupica Mountains, Nežilovo, Veles Municipality, North Macedonia, nežilovite occurs in pink dolomitic marble from a metamorphic complex of gneiss, schist and marble. It is associated with plagioclase, chlorite, phlogopite, cymrite, talc, piemontite, baryte, hedyphane, braunite, gahnite, franklinite and hematite.
The crystals are about 0.2 to 1 mm in size. They are thin tabular and have subordinate hexagonal prism faces. The simple habit resembles that of hematite, but nežilovite has a dark brown or nearly black streak and is magnetic (CM 34.1287-1297).
