Outrageously good museum-sized plate of light grayish-purple 2 cm cubes of Fluorite. The cubes (there must be over 60 of them!) have excellent luster and the classic superb fluorescence for which the term actually was derived. Yes, the effect of fluorescence was defined based on glowing fluorite from this locality! To raise the bar even more, there are well-formed Galenas to over 5 cm which have very good luster. Greater yet, there are three generations of epitaxial growth that go quartz-galena-quartz. I have rarely seen an English Fluorite this large that matches this superb specimen for quality and interest. An amazing combination piece from one of the world's great fluorite districts. A true old-time classic from the J. Cilen Collection. Locality is almost certainly Blackdene Mine in Weardale. But, it could be one of several mines in the area that were operating over time.
