Hi,
I think that radiocarbon dating might be a wee bit expensive. I know that it's probably cheaper and more accurate now but you might still have to be prepared to part with a couple of hundred dollars.
Re the intricacy of the piece, and it is wonderful, I would not underestimate the talents possessed by some of our ancestors.
It was great to see the video, and what that has thrown up is the pristine condition of the piece. If it is ancient then it has been extremely well looked after.
Let us know what the Archaeology Dept say.
