Eulytine is a rare bismuth silicate, with cubic (actually tetrahedral) symmetry. Breithaupt (1827) named the mineral after the Greek for "easy breakdown" since the mineral decomposed with heat. Eulytine forms brown tristetrahedral crystals on quartz matrix. On this specimen, the maximal crystal size is approximately 0.5 mm. This specimen comes with a label from the Beragakadamie (Mining Academy) Freiberg and a label from the Joseph Urban mineral collection. Joseph Urban was a collector/dealer based in Tucson, honored by the mineral name jurbanite.
