We've all heard of 'six degrees of separation', the idea that everyone in the world can be connected in just a few steps. But what if those steps don't just relate to people but also to viruses, neurons, proteins and even to fashion trends? What if this 'six degrees of separation' allowed us an insight into something at the core of Nature? We used to think the way in which web pages, power grids and people tied together was more or less random. But recently two young physicists independently discovered that fundamental laws govern networks. It's a discovery that may prove as important as Newton's observations of gravity or Darwin's theory of evolution.

All around us is Earth's bounty - spectacular mountains, Caribbean blue oceans and abundant, delicious food crops. But what we can see is only a part of the riches Earth provides. Its hidden assets are some of our most important natural resources, and they have helped shape humankind. They are the metals that have built our modern cities and the fuels we need to power them. They are the sparkling gems whose beauty excites us and the many other minerals essential to the tools we use every day. We simply could not live our lives without these resources. This program takes us on a journey deep inside the Earth to uncover the mysteries of how these treasures were created, and explores how they have allowed humans to evolve and build great civilisations. As the quest continues, we are discovering that some of our treasures may soon run out. Looking deep into these ancient resources, we reveal new secrets that will help us solve the problems we face today. Their beauty has captivated us for millennia. Their cost can be extraordinary - some are even considered priceless. Precious gems like diamonds, rubies, emeralds, opal, and jade are the ultimate treasures of the earth, and each one is made from a specific - and often torturous - recipe of chemistry, pressure, and heat. The secrets to their sparkle, colour, and even strength lie deep inside the gems themselves, but could they also hold clues to one of the most enduring mysteries in the field of geology? From Tiffany's workshop in New York to the sapphire mines of Sri Lanka, from North Carolina's emerald fields to the jade-laden Forbidden City of China, join us as we explore the fascinating science of gems.
