"Over a dozen octahedral Scheelite crystals perched on white Quartz. Scheelite is a popular mineral for collectors. It forms perfect tetragonal dipyramidal crystals that look very much like octahedrons. These pseudo-octahedral crystals are sometimes truncated with minor pyramids, but only on the top and/or bottom points of the crystal; giving evidence of their true symmetry. Scheelite fluoresces a bright blue under short wave ultraviolet light." Location: Yaogangxian Tungsten Mine, Nanling Mountains, Hunan Province, China Size: 15.2 x 6.4 x 3.8 cm. Weight: 1.0 lbs.
