Fluorite

specimen number:
9892002

location:
Okorusu Mine, Otjiwarongo, Otjozondjupa, Namibia

description:
Beautiful glassy color zoned green and bluish purple cubic crystals of fluorite measuring to 2.5 cm on edge on matrix. Some damage present as seen, still quite good. Crystallized all around, beautiful when backlit.

The Okorusu Mine, located in the Otjozondjupa Region of Namibia, is centered on a Cretaceous alkaline ring complex discovered by German geologists in the late 19th century. Geologically, the deposit is formed within a carbonatite and syenite intrusive complex where fluorine-rich hydrothermal fluids interacted with country rocks to create massive, high-grade fluorite replacement bodies. Modern industrial open-pit mining began in the late 20th century, supplying acid-grade fluorspar to international markets while also producing world-renowned crystallized mineral specimens for collectors.
