Mineral Specimen #5334 Ferberite, Quartz with Included Scheelite, Twinned Calcite, Fluorite
Yaogangxian Mine, Yizhang Co., Chenzhou Prefecture, Hunan Province, China
6.8 x 3.2 x 4.2 cm
This specimen is a very interesting assemblage of several species. Well formed, black colored, striated Ferberite crystals are found on the side of the specimen where they have grown on the sides of Quartz crystals. The Quartz crystals are well formed with a high luster and are for the most part clear. Although not visible, there are apparently micro Scheelite inclusions in the Quartz which fluoresce a bright blue/white, giving the appearance of fluorescing Quartz crystals. Overlaying one side of the specimen, and the tops pf the Quartz and Ferberite crystals, there are stacks of twinned, thin, wafer like, hexagonal Calcite crystals. These crystals are slightly off white in color and have small, dark colored, inclusions of an unidentified material. Scattered about the specimen are small, cubic Fluorite crystals which are well formed, transparent and have a high luster. The color of the Fluorite crystals ranges from water clear to light purple.
Flaws: Nothing Appreciable
