1 I found this piece covered in a thick concretion, it has been like all of my finds been reported to http://www.teesarchaeology.com/ who have after a long inspection of the artefact, decided it is either the end of a light bulb - a spark plug - or meat Fork ! who am I to disagree ! ?

The grey blue piece I believe to be Basalt
5 The artifact 
6 The shroud I believe to be worked and polished magnetite .
7 These 2 images show 2600 year old gold from Germany, that look very similar to the worked band on this artefact , so do we have worked Magnetite of Scandinavian origin and Celtic gold ?

10 - If this piece is not ancient I would find it just as fascinating ie why ? 
11 - The components ive removed and cleaned so far.
12 - In my mind so far we have a bone handle, a very thin gold clasp, and a shaped magnetite piece ? 
13 - What I believe to be shaped magnetite.
14 - This piece is highly magnetic !

I have now cleaned most of the concretion residue from the artefact, and if ime honest I no longer believe the piece to be a knife handle , I think ive been looking at it upside down ! I now believe it could have been an Amulet or Talisman , I took the very thin corrugated none ferrous band to a local jewellers today, and they agree with me that the piece could not be copper bronze or aluminium, and although the piece is too thin to get a reaction with there standard acid test, everything points towards the piece being gold
I have gone as far as I am willing to go on the cleaning of this artefact !
1 - All components now free of the thick concretion . 
2 - Close up of the carved bone where the gold band would fit .

4 - Both the bulbous and straight piece are ime sure shaped Basalt, it shows no signs of oxidisation, and looks and reacts like no metal ive seen before ? .

6 - The Artefact
I Believe this artefact hung from the neck via a chain or lace, ie I think it was believed to protect or give good luck, ie a Talisman or Amulet ? But maybe http://www.teesarchaeology.com/ are correct and its a spark plug etc ?
