A gold ring and necklace have been discovered in the fake bottom of a mug on display at the Auschwitz museum in Poland.
Curators found the jewellery while carrying out preservation work on its collection of enamel kitchenware.
The Auschwitz-Birkenau State Museum said the jewellery - like other objects accidentally discovered - would be carefully documented and secured, but warned that the likelihood of finding the owners was slim "because there are no traces left on the objects to help identify them".
It was common for Holocaust victims to hide their valuables in their luggage when they found out that they were due to be removed to death camps.
