Police have released images of items of jewellery in a bid to reunite them with their rightful owners.
The items were recovered from a vehicle which was found abandoned in Watford on December 6.
It is believed they may have been stolen during a series of burglaries across Hertfordshire.
Officers are appealing to victims of burglaries to look at the photos and contact them if they believe they own any of the items.
Anyone who recognises them or has information about where they may have come from is asked to contact Detective Sergeant Kerry Bull via the Hertfordshire Constabulary non-emergency number 101.
