A twinned calcite crystal from Kentucky, perched on a small scrap of matrix. There is absolutely no damage to this piece, both terminations are intact.

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)
