Fess up, lads.
A royal tiara steeped in historical significance has been stolen from the Harley Gallery at Worksop, Nottinghamshire, UK.
The incident occurred earlier this week, between 21:45 and 22:00 GMT on Tuesday and police have since appealed for information.
The tiara was a Cartier creation made for Winifred, Duchess of Portland, to wear to the 1902 coronation of King Edward VII.

The BBC has reported that the thieves used power tools to smash through an armoured case and had an alleged getaway car – a silver Audi S5 which was later found burnt out in Cross Lane, Blidworth.
The publication spoke to James Lewis from Bamford auctioneers in Derby said it had been “designed in a period when money was no object”.
The main feature in its design is the Portland diamond, but the tiara features a number of other diamonds and is all set in gold and silver.
With the item being so conspicuous, it is feared that the tiara could be broken up and sold in parts if it is not procured soon.
