A gold lunula from Llanllyfni, dating back to the early Bronze Age, was stolen during a recent heist at the National Museum of History, police have revealed.

Two men from Northampton have been charged after a haul of gold jewellery was stolen from a display case at the St Fagans museum in the early hours of October 6th

But detectives from South Wales are still trying to recover the missing valuable items - including the lunula, a decorated crescentic ornament in sheet gold with two twisted terminals.

Also missing are three hoards of gold items and armlets from the Powys and Carmarthenshire areas.

Detective Inspector Bob Chalmers from South Wales Police said: "While two men have been charged, the investigation is very much continuing."

"We are focussed on locating the outstanding stolen items so they can be returned to their rightful home. We urge anyone with information to please contact us as soon as possible."

Jane Richardson, chief executive of Museums Cymru, added: "We’d like to thank the police for their continuing investigation into the search for these invaluable and irreplaceable items that are part of Wales’ history, heritage, and culture."

"I’d like to encourage anyone who may have any information about their location to come forward to the police so that they can be returned to their rightful home within Wales’ national collection for everyone to access and enjoy."

Gavin Burnett (43) and Darren Burnett (50) are due to appear before Northampton magistrates on Tuesday charged with burglary.

A 45-year-old woman from Northamptonshire arrested as part of the investigation remains on police bail.
