For generations the Eggerdink family has been exporting “Black Stone” to all corners of Europe. The black rocks from the Doornik area date from the Carboniferous Period 359 to 345 million years ago. The black stone is a dark limestone which takes a polish. It is also hard enough to have been used locally for pavements and kerb-stones. It is sometimes called Doornik marble, though this is geologically inaccurate. Enjoyed by people from the south east corner of Belgium for centuries and finally the attention it needs. And deserves.
