Pearls, silver cutlery and an "intricately designed glass decanter" were all stolen after a house was burgled in St Albans.
Hertfordshire Constabulary said the house in Cromwell Close was broken into between 4pm on Friday, November 14 and 1pm on Monday, November 17.
The offenders allegedly forced their way into the house after breaking a lock on the door at the rear of the property.
Officers said a white gold cultured pearl necklace, pearl earrings, a silver Ronson cigarette lighter, silver cutlery and silver plated platters, a "intricately designed glass decanter" and a black bowler hat, which has the victim’s name written inside, were all stolen during the break-in.
No one was at home during the burglary.
Detective Constable Dean Trollope from the St Albans Local Crime Unit is investigating and said: "The items stolen are particularly distinctive and I would like to speak to anyone who has been offered them for sale or knows of their whereabouts.
"I would also like to hear from anyone who may have seen or heard anything unusual or suspicious between the stated times in the area. Any detail, however seemingly insignificant, may prove very useful to my investigation, so please do contact me."
