A famous diamond-encrusted tiara has been stolen from The Welbeck Estate in Worksop, Nottinghamshire. The 6th Duke of Portland commissioned Cartier to create the Tiara for his wife in 1902. It was made using diamonds from the historic collections of the Dukes of Portland and features the 19th-century Portland Diamond at the centre, flanked by two diamond drops and other pendant diamonds. The exquisite piece was worn by the Duke’s wife to the 1902 coronation of King Edward VII and is one of Great Britain’s most exquisite historic tiaras.


Burglars reportedly used power tools to break into the Portland Collection Gallery at The Welbeck Estate on the evening of Tuesday 20th November. They proceeded to steal the tiara and a diamond brooch from a glass display case while the alarms were sounding.


Police are investigating and appealing for information about a silver Audi S5 suspected to have been involved in the robbery. They are also asking anyone with any additional information regarding the crime to get in touch, or contact Crimestoppers.
