They could be loom weights couldn't they? and they could have been buried with a woman, perhaps so she could carry on weaving in the next world. Like it was mentioned above, lots of people have been buried with useful or personal objects. And they wouldn't need to look worn, because they don't get worn, they just dangle off a loom.
or fair enough, they could be anything
by the way, I heartily recommend devizes museum to anyone passing. it's a bit cramped but the gold objects out of one of the barrows near stonehenge - fantastic stuff.
