Druse of sharp cubic crystals of Fluorite, with well-defined faces and edges, very bright, transparent, and with sharply contrasting phantom growths, in a deep mauve and light yellow color, both colors being rare at Okorusu, where green is usually the dominant color for Fluorite.
The Okorusu mineralization is associated with a Cretaceous alkaline carbonatite complex. Fluorite occurs in cavities and fractures formed during late hydrothermal processes related to the carbonatite intrusion.
The locality is internationally known for its high-quality Fluorite crystals, typically green, although yellow, mauve and bicolored specimens are also found.
Okorusu Mine, Otjiwarongo District, Otjozondjupa Region Namibia (2009)
Specimen size: 15.5 × 14 × 4 cm = 6.10” × 5.51” × 1.57”
