Hundreds of thousands of pounds of jewellery recovered from a travellers site at Highbridge, near Burnham-On-Sea, appeared on the BBC1 show Crimewatch on Wednesday evening in a bid to trace the owners.
The jewellery was recovered during a warrant in Highbridge in August last year.
Police believe it may be stolen and some of the jewellery has been traced back to nationwide jewellery shop robberies.
Avon and Somerset Police has carried out enquiries all over the country and are now appealing on national television for anyone who recognises the jewellery to come forward.
Among them is a £35,000 diamond ring and a £65,000 pair of diamond earrings.
DC Andrew Jones told Burnham-On-Sea.com: “We are keen to trace the owners of these valuable items some of them appear to be of sentimental value and anyone who recognises should contact us.”
Anyone with information to DC Jones at the Serious Crime Group on 0845 4567000 or Crimestoppers on 0800 555 111.
