Images of jewellery stolen from Watford and Kings Langley have been released in an attempt to reunite the goods with their owners.
The items seized include watches, earrings, bracelets and necklaces, thought to be stolen from residents in Watford, Kings Langley and Hemel Hempstead.
The jewellery was located following a search of a vehicle on Friday, October 18 last year.
DC Georgina Fenge, from the specialist investigation team, said: "Despite our best efforts to find the owners of these items we have so far been unsuccessful.
"We would like to hear from anyone who believes they may recognise the jewellery. It’s possible these items hold significant sentimental value and so it would be great to be able to return the items to their rightful owners."
If you recognise the items telephone DC Fenge on 101.
