Margin of Error:

Locality type:


A vast area extends close to over 200 km. Until the late 1990's quartz crystals from this area where sporadic & hardly known to collectors. Vuggy hydrothermal quartz-carbonate veins which shows vast epithermal & supergene overprint are widespread & host these crystals displaying hematite coated, multi-phantom, amethyst crystals often as scepters and caps. Similar isolated finds have been discovered at a few localities, a particular find was on Girtis Farm, named as the 'Kalkgat' pocket.

Note: There are no distinguishing features to separate specimens from Namibia or those from the South African side of the Orange River (KL von Bezing personal comment June 2013). Complicating the issue of origin is that between 2003-2005 most specimens originated from localities on the South African side of the river and the same issue could be said for Fluorite from this area!

Fluorite
Formula: CaF2
Description: In the orange river quartz area fluorite occurs in crusts of colourless to purple rounded crystals, occasionally. It is unclear which of the specimens labelled Orange River are from the Namibian side as most may actually come from the South African side.
