The Fylingdales Stone 1

No I think it does matter, I can't comment on what state the object is "said" to be in.

If burying it can be shown to give the object a shorter life than some other means of conservation tell me about it - give me the facts - what will cause the erosion, how long will it last?

There are comments, further up this thread, from the people who laser-scanned it, about the potential deterioration of the stone.
