The author tries to convince that these stones are so ordinary, ostensibly to argue that they will not be stolen. However, watch what happens as these stones start to develop a provenance and get photographed and documented along the way.
Reading this I had a flicker of desire to steal "Lily of the valley", and likewise this desire to take hold of such a rare coveted object will grow in the hearts of man over the centuries. What gives something value is not always its intrinsic worth, but also how it takes hold in the public consciousness. Just look at worthless NFTs.
