The family business started with a jewellery showroom and manufacturing workshop in a windmill in Guernsey; later expanding the business to another windmill premises in Jersey.

Commenting on the new London shop, business owner Catherine Best said: “We have been looking in London for a while, secretly hoping to find the right premises for our jewellery.

“It all happened very quickly and we are now working hard to open our new showroom and workshop in Mayfair towards the end of the summer. Over the years the team in the Channel Islands has grown so much and now London means we can expand further. We are all extremely excited.”

Ms Best’s daughter, Vikki Freeman, who also works as a jewellery designer for the company, added: “Mum, the whole family and the teams in Guernsey and Jersey have worked hard over the years to build our business. Opening in London is the icing on the cake.

“We look forward to welcoming clients, existing and new, to our London shop and, of course, at the same time continuing with our commitments in Guernsey, Jersey and online.”
