Jewellery thieves who targeted a gold centre at Ellesmere Port Market are thought to have gained access to the stall by cutting a hole in its roof.
A large quantity of jewellery was stolen during the incident at Golden Balls sometime between Thursday evening (April 21) and the early hours of Friday morning (April 22).
Ellesmere Port resident Jayne Lyth, 50, has been left devastated after her diamond engagement ring was among the items taken.
Jayne, who had taken her precious ring to Golden Balls to be cleaned, told the Chronicle: "I am very upset. It was the first diamond I ever got and I had it blessed when I got married.
"I know I can get another one but it is not the same.
"I am absolutely gutted and I just cannot believe someone has done this."
Now police are appealing for information about the burglary.
Detective Constable Kevin Hole said: “This incident has left the trader extremely shocked and I am keen to speak to anyone who believes that they have any information which could help bring these offenders to justice.
“The trader is particularly distressed as many of the items taken during the burglary did not actually belong to him, but were irreplaceable items owned by other people who had taken them to the stand to be repaired.”
Anyone with any information in relation to the incident is asked to contact Cheshire Constabulary on 101 quoting incident number 123 of April 22.
Alternatively, information can be reported anonymously to Crimestoppers on 0800 555 111.
