Fluorite, Okorusu (Otjiwarongo) 4.7cm

Zoning & Coloration: Okorusu (Otjiwarongo) is world-famous for simple to modified green cubic fluorites featuring deep purple, cranberry, or smoky-violet phantom centers and bases (particularly from Pit A and Pit B).

Luster & Translucency: Okorusu fluorites frequently display this exact slightly waxy-to-glassy, translucent mint/sea-green body with saturated purple core zoning.

Matrix / Attached Minerals: Okorusu is a carbonatite/skarn-type deposit (often associated with limonite/goethite gossan matrix and calcite), whereas Erongo fluorite is pegmatitic and typically found alongside feldspar, muscovite, quartz, or schorl. The brownish iron-stained base on this piece matches typical Okorusu gossan matrix.
