"This technique of lifting a sample from the surface of stone and scanning it could ultimately lead to us feeding the results into a national database, providing an indication of where geographically that sample came from. This can be done by comparing the stone samples with other stone located across the country and could prove to be a useful point of reference for those tackling stone theft."
