The group will continue to operate as an independent entity and join a number of other companies operating across the UK and Europe, including Cookson Precious Metals.
Heimerle + Meule was founded in 1845 and is one of Europe’s largest precious metal suppliers.
In a statement Andrew Morton, managing director of WB, said “retention of independence” was a key consideration for previous owners Vivian and Patrick Fuller, who sought the best options for future growth of the business.
Morton said: “Following more than 40 years of dedicated and inspired leadership and development, I am sure you will join me in wishing them the very best as they retire from full-time jewellery manufacturing and management.”
He added: “I would also like to take this opportunity to confirm that there will be no changes to the way that we operate. We will enjoy a high degree of independence as part of the Heimerle + Meule Group which means that in many ways nothing will change for our key stakeholders.
“I will continue to lead the WB Creative Jewellery Group, alongside my senior management team, with the added benefit, backing and security of the Heimerle + Meule Group. I look forward to continuing to work with you, as we embark upon a new and exciting phase for our business and for the trade.”
