Thumbnail Fluorite Octahedrons, Riemvasmaak, Northern Cape, South Africa
One Fluorite octahedron from Rievasmaak, Northern Cape, South Africa Under long wave UV these crystals fluoresce blue. You may not get the one in the pictures but they are all similar.
These octahedrons were cleaved from large pieces of fluorite by knocking of the corners to reveal this shape.
Each order comes in a thumbnail box as pictured. These boxes are sometimes called perky boxes and are meant to hold small specimens. The dimensions of the boxare 1.25' square.
We were very lucky during our March 2017 trip to South Africa to purchase a large collection of Orange River Fluorites Octahedrons from Riemvasmaak in the Northern Cape, South Africa.
The cause of the beautiful green colour is unknown, it may be related to associated radioactive or rare-earth species, samples where tested and yielded surprising results; isotopes in the rare-earth element lanthanide series; lanthanum, ytterbium, cerium, neodymium, samarium, europium, gadolinium and holmium were detected although amounts were not determined.
