With the art world on high alert for any sign of the missing Louvre jewels, one Italian collection says its method of creating a photographic fingerprint of its own priceless gems and artefacts could make them harder to break apart and sell on.
A team of gemology experts has spent more than a decade studying the most valuable pieces of the collection at Naples' Tesoro di San Gennaro. Using microscopes and specialised equipment, the team has photographed more than 10,000 stones, Reuters reported.
