A GEM of a jewellery designer has proved her 18-carat worth by being chosen for an exhibition.

After graduating with first class honours from Cleveland College of Art and Design, Joanne Riddle set her heart on starting her own textile business.

Within months of finishing her course, she had won backing from Stockton Borough Council, the Prince's Trust, and the Ropner Trust to set up the JL Riddle Design Studio, at the Stockton Business Centre.

In less than a year of business, the 24-year-old, of Upsall Grove, in Fairfield, Stockton, has already built up a loyal following of clients.

Now she has been invited to display her work at one of the design world's most prestigious exhibitions.

Miss Riddle's distinctive designs, including fabric cuffs and chokers, are among those from only 75 Prince's Trust companies to be chosen for the Top Drawer show, at London's Earl's Court Olympia.

She said it will be an honour to take part in the international event, which runs from Sunday to Tuesday.
