A Neolithic polished stone axehead was found in 1957, on land to the east of Grainsby. The axe is held by Lincoln Museum. {1}{2}{3} The axe was thin-sectioned and found to be made from a tremolite form of jade known as nephrite. {4} It is now known that the stone used to make jadeite and nephrite axeheads in the early Neolithic period was quarried from high-altitude quarries in the Swiss and Italian Alps and northern Apennines. The axeheads were then exported from the Alpine region across the continent of Europe eventually reaching Britain and Ireland. {5}
