Museum staff at Auschwitz discovered a gold ring and necklace hidden at the bottom of a mug at the former Nazi concentration camp, according to a report.

The discovery, reported by AFP, came as the material at the bottom of the mug degraded and separated. Workers said they would not be able to identify the owners but assumed it was hidden by someone who thought that the Nazis had planned to resettle rather than kill them.

“We can see the fear of the person because they hid the jewelry,” Pawel Sawicki told the AFP. “But in a way we also see the hope that the person had [for their survival].”
