Police are hoping to reunite haul of stolen jewellery with its rightful owners.
The valuable stash was discovered in a house in west London, but officers believe the items could have been taken from anywhere in Herts.
Burglary victims are being asked to view the jewellery – seized after a warrant was carried out on the Hayes property on July 25 – to see whether it may belong to them.
Along with the gold and silver chains and pendants, two 160GB black iPod classics and a Cannon lxu51115 digital camera were also found.
Det Con Solomon Beere said: “We have been making attempts to trace possible victims and reunite them with their stolen property, however, we have some items outstanding.
“I would ask anyone who has been the victim of a burglary in recent months, particularly around the Watford area, to view the photos and if they do recognise anything, contact me.”
If you recognise the items or have any information relating to thefts, call DC Beere on the police non-emergency number 101, or Crimestoppers anonymously on 0800 555 111.
