US collector Breck P Kent recently showed of his wonderful specimen of calcite from Stank Mine in the (then Lancashire) part of iron mining area of Cumbria, North West England.
Stank Mine is famous for its scalenohedral calcite, often with characteristic red/maroon haematite inclusions.
The mine operated from 1871 to 1901, was also known for its pseudomorphs of haematite after fluorite and calcite with rounded outlines to the original crystals.
I am not aware of any specimens recovered since, so a scarce locality. Breck's specimen at 10cm X 8cm X 6cm is a beauty.
