Bedfordshire Police are appealing for information from anyone who recognises any of the pieces of jewellery featured in this picture.
The appeal for information about the items, believed to have been stolen, follows the arrest of a man on Saturday, September 21.
He was arrested on suspicion of a number of burglary offences.
During their investigation, police found pieces of jewellery which they say the man could not account for.
Now they have released this photograph in the hope of tracing the rightful owners of these items, which could be from anywhere in the county.
Det Con Victoria Willett is keen to hear from anyone who may recognise them.
She is also interested in speaking to people who may know where the items have come from.
Anyone who has information about the jewellery is asked to contact Det Con Willett, in confidence, on 01234 275342.
Alternatively, they can call the police non-emergency number 101.
Or text information to 07786 200011.
Information can also be passed on to Crimestoppers, anonymously.
Contact the charity on 0800 555 111, or via www.crimestoppers-uk.org.
