Police are investigating after jewellery was stolen from a house in Oakley Road, Luton, on Sunday, October 30.
The intruders forced a door and window open between 1.20pm and 7.40pm, while the occupants were out.
They searched the house and stole a number of items of jewellery and a large sum of cash.
Detective Constable Allan Taylor, investigating, said: “Some of the jewellery is of sentimental value, and we are keen to reunite it with its owners.
“If you recognise any of the items pictured, possibly because someone has approached you offering to sell them, I would urge you to come forward.
“Similarly if you know who is responsible for the burglary, please contact us.”
If you have any information about the burglary, contact DC Taylor, on 101 quoting reference number C/44519/2016.
