Although it has the look....you know...."the look", It bothers me that the reverse looks like it has been chipped away from a larger piece but the front decorative side seems to be perfect in form around all the contours of the edges.The stones color too does not look consistent throughout, especially where the chipped parts are. If it were buried for that long a time I would think it would not look as fresh. Surely someone else will chime in to counter or support that theory, I could be wrong. It does look old though.
