Is there a stone that fits?

There is a stone at the garden tomb that Bob is standing next to, but this is not the stone as it is far to small

If there was a stone that fits, surely it would be 1 in a million!!

If there was then surely wouldn't you agree this would be the GREAT missing piece to this puzzle?
