PURPLE FLUORITE
De'An Mine, Wushan, Jianxi Province, People's Republic of China
The highly desirable Fluorite specimens from the De'An Mine have a number of specifically identifiable characteristics: they display either an octahedral habit or a dodecahedral one, with no cubic crystals being seen. In addition, virtually all are surrounded by a thick layer of colorless/white Quartz which must be removed in order to see the crystals. Usually this layer is selectively removed via acid etching while leaving enough material below the crystals to serve as a contrasting matrix. The acid etch technique destroys any euhedral Quartz associated with the Fluorite but it is easier, and requires less skill, than the mechanical removal displayed by this example. Two classic dark purple dodecahedrons are securely nestled within their enclosing white matrix, whose surface is covered with the euhedral Quartz crystals mentioned above. Both Fluorites are free from damage and show a reddish-purple hue and fine luster. Normally, crystals from here show a matte surface luster when exposed. In excellent condition it measures 5 ½ x 3 x 2 5/8 inches and has a custom labeled base.
