David is the son of a diamond merchant and buying and selling is in his blood. He was awarded the Best Independent Pawnbroker award in 2008 by the National Pawnbroker Association.

He believes the secret to his success is treating everyone the same - whether they have a £1 million ring to sell or one worth £100.

'There are three words to describe me: 'The Deal Maker'. Dealing is in my blood, it's all I know,' he says.
