British Museum's Recovered Gems on Display The British Museum has recovered stolen gems and jewelry, some dating back to ancient Rome, with the help of police and art dealers. The exhibition "Rediscovering Gems" showcases these tiny artifacts, known as cameos and intaglios, with a focus on their historical significance and craftsmanship. The museum aims to be transparent about the thefts and recovery efforts. The exhibition sheds light on the underappreciated beauty of these gems and their significance in ancient times, including their use as seals and gifts.
