Quartz on Fluorite (South Africa)
Riemvasmaak, Northern Cape, South Africa. 90mm x 50mm x 35mm.
Well defined fluorite octahedrons are completely covered with a fine layer of quartz. This is how a lot of the well known Rienvasmaak quartz was recovered, with acidic treatments the quartz has later been burned off to reveal the fluorites. We enjoy this specimen simply as it is as one would find a lot of the material in situ in the deposit. Packed shipping weight +/- 360gr.
