“A very interesting specimen showing a very nice quartz-after-(?) pseudomorph on smoky quartz crystals. Though it is not obvious on the picture, external shapes suggest that the original mineral could have been baryte. As fluorite, baryte is very rare in the quarry but it is common to find pseudomorphs.
This one is very aesthetic because of the difference in color between the pseudomorph and the matrix.
