Jewellery made from Durham Cathedral stone, a kinetic phone charger, an armrest for breastfeeding mothers and a mobile science table for schools in less developed countries were just some of the innovative products young people taking part in a flagship entrepreneur competition came up with.

Winners of this year’s Future Business Magnates (FBM) competition, run by Business Durham, the economic development arm of Durham County Council, were announced at an evening reception at Newton Aycliffe’s Xcel Centre.

More than 15 school teams from across County Durham had entered the competition, with this year’s challenge – Made in County Durham, Sold to the World – focusing on exporting.

The overall winners were St Leonard’s Catholic School in Durham for their business idea to make jewellery from Durham Cathedral stone. Judges felt that the product had a great fit with the competition theme and were impressed by the team’s excellent presentation of their business idea.

Second place went to Park View School, Chester le Street, for their bracelet and necklace designed to help address social isolation and third place was awarded to Durham High School Girls for their History in the Making gift kits themed around Durham’s history.

Influential names from the business world, including Bignall Group, Ebac, Hydram, Waterstons, CA Group, Robertson Construction, Roman Limited, Franks the Flooring Store and Zumtobel Group had partnered the teams to provide mentoring and support.
