IF Kosher stones are even a remote possibility of being available to you, then Rob must be selling those only to Belgians! Rob told me the Ardennes mine only offers up to the select grade and does not offer Kosher stones. That was last year, so maybe if one begs and pays whatever price must be paid to get one, there are Kosher coticules avaible to the public?
