A cluster of vibrant-green, octahedral fluorite crystals in superb condition from a surface deposit located 3 km north of the village of Riemvasmaak. The cause of the beautiful green color is undetermined, however, the color may be related to traces of radioactive or rare-earth elements. Fluorite samples from Riemvasmaak were 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. When found, these spectacular green octahedral fluorite crystals are partially to completely covered with druzy quartz crusts. The druzy quartz crusts are usually selectively removed by hydrofluoric acid to uncover the beauty of these fluorite specimens. Dimensions (cm): 7 H x 8 W x 2.5 D. Location: Riemvasmaak, Kakamas, ZF Mgcawu District, Northern Cape Province, South Africa
