The Bennett family run Britain’s number one retail jewellery business - without having a single shop. Their customers buy jewels having seen them on cable TV. They have a close relationship with the owners, because Steve and Sarah Bennett – their son, aunties, in-laws and cousins – are frequently on screen. The Bennetts broadcast to Europe and North America 24 hours a day, every day of the year, helped by a team of presenters who talk minerology for four hours at a time, and mix their sales patter with jokes and high jinks that have viewers dialing in at a furious rate - up to three thousand calls an hour, and everyone who gets through to the call centre wants to buy, making up to a quarter of a million pounds worth of business in just four hours.

The Bennetts’ business is based on two natural resources, the first being minerals. The number one best-selling stone is a blue African gem called Tanzanite. It comes from just one outcrop in Tanzania, and the lode is running
