When I saw these pieces, I thought there had been a labeling error- they look very similar to pieces from Asturias, Spain. That was not the case-- further inquiries and a bit of research proved that these actually are from Kentucky.

Apart from millerites , I haven"t seen many specimens from this state, though I am told by friends that there quite a few field collecting sites there. I suppose that would make sense, given that the same geological forces responsible for producing the Elmwood deposits and Illinois flourspar district also acted in this area (for those outside the US, Kentucky is sandwiched between better known mineral districts in southern Illinois and western Tennessee)

This specimen is at least a couple decades old. I did an internet search, and the quarry where they were found is still in operation-- it supplies crushed stone and material for making concrete.

There are a couple spots of damage on this one.
