Gold

It's soft, shiny and rare. A symbol of love, of power, of wealth - gold has been prized for thousands of years, its value rises and falls as the economies round it fluctuate. Yet there's only a limited supply of it and demand is high: for jewellery, technology, by central banks and investors. But after more than a decade of rising prices, the value of gold is down. So how to make money from this precious metal? Evan Davis and guests follow its journey from the gold mines of west Africa to the workshops of an east London jewellery maker. What are the risks, responsibilities and rewards for those who mine it, invest in it and manufacture with it?

Guests:
