Allied Gold and Brown and Newirth owner AG Group has announced that it has opened an in-house assay office at its group headquarters.
The move follows a historic agreement with the Sheffield Assay Office, marking the first-ever fine jewellery manufacturing Sheffield sub-office.
The partnership has received full approval from the British Hallmarking Council, with operations set to begin early January 2025.
The range of wedding and engagement rings, chain, and fine diamond jewellery from Allied Gold and Brown and Newirth will now be assayed at the new facility.
Jerry Anderson, CEO of AG Group, said: “We are incredibly proud to have received approval from the British Hallmarking Council to open a Sheffield Assay sub-office at our new headquarters. This will significantly streamline our operations, boosting efficiency and reducing lead times for our trade partners. We are excited to unveil this state-of-the-art hallmarking facility and to deepen our relationship with Ashley and the Sheffield Assay Office team.”
Ashley Carson, assay master and CEO, added: “This is a thrilling new chapter for the Sheffield Assay Office. Our partnership with the AG Group allows us to expand our hallmarking services and continue delivering the exceptional standards we’re renowned for.
“As the jewellery industry evolves, we’re committed to supporting British manufacturing with the same precision and integrity that Sheffield has been known for over centuries. I would also like to extend my thanks to the British Hallmarking Council for their efficient approval allowing us to proceed smoothly with this initiative.”
