Via the Old French jaiet name was further corrupted to git. The Dutch scientific name is gagaat. Git is a fossil with a density of 1.23 kg / dm at the time of the Jura high-pressure mud originated from 135 million-year-old wood from the Araucariaceae family tree. It is found in two forms, hard and soft, with a hardness of 4 resp. 3 on the Mohs hardness scale. The hard type is the result of the compression of carbon in salt water, while compression carbon in fresh water yields the soft type. Git is easy to polish and is used for jewelry and art objects. The low density makes it possible to make large, but not too heavy to make jewelry. In the Neolithic megaliths in Drenthe are already beads of jet found. Bede in his Ecclesiastical History gentis Anglorum in which 731: Britain and many excellent manufactures jet, a black and sparkling, glittering in fire; fired scaring the snakes and as it is warmed by rubbing, anything you hold against it, like amber on to it.
