Detectives are looking to trace these distinctive items of jewellery, which was stolen from a house in Chelmsford during the week before Christmas.
Officers have this afternoon released these images, in the hope jewellers, pawnbrokers or second hand goods shops may recognise them.
They were stolen from a house in First Avenue on December 18, between 9.30am and 7.55pm.
Burglars smashed a rear window to get in before then forcing open a door inside and carrying out an untidy search of the house.
They then forced a window to the front of the house to get out.
Among the items taken were some gold-plated Concorde cufflinks, an antique pearl and ruby ring, a gold ring that looks like a belt, and a gold ring with a masonic symbol on it.
Detective Sergeant Phil Greaves, of Chelmsford CID, said: "All of these items are quite distinctive and I'm confident if anyone was offered these pieces for sale that they would remember them.
"If anyone knows of the current whereabouts of this jewellery or has any other information about this break-in I would urge them to call me at Chelmsford Police Station on 101 or ring Crimestoppers anonymously on 0800 555 111."
