I've carried on removing the earth from the area to the left of the exposed gold. The crushed gold object is longer than we expected at about 20cm. We've shown pictures of it to various people and it seems it may be a torc (a large necklace). It is made of sheet gold and would originally have been formed over an inner core of wood so that it looked like a large solid gold object. We can see now that it has fine decoration on its ends and was probably deliberately crushed and twisted before burial.
