The Blanchard Mine is famous for its fluorites, but if you talk to collectors there, what they most prize are the hard-to-find specimens of bright blue (and very RARE) linarite ((Lead Copper Sulfate Hydroxide). Typically, as here, linarite forms in thin plates (or sometimes dendritic, flattened crystals) on the surface of quartz, or on galena pseudomorphed on its surface to cerussite. There is a lot of linarite here! Accompanied by a label from English dealer Ralph Sutcliffe.
