How have Earth’s most extraordinary natural resources driven the rise of civilization?
They grace the crowns of royalty, sharpen weapons of war, and both power and pollute our cities. They are Earth’s natural resources: treasures in the forms of stunning gems that we hold dear, metals that have altered the course of civilizations, and fuels that drive our modern world.
TREASURES OF EARTH "Gems" (Aug. 9, 2017), "Metals" (Aug. 16, 2017), and "Power" (aired Nov. 16, 2016), is a three-part series that will take us on a journey deep inside Earth to uncover the mysteries of how these treasures were created, and to explore how they have allowed humankind to progress and build our great civilizations.
But even as that quest continues... we are discovering that some of our treasures may soon run out or have unintended consequences that bring new perils.
Can our ancient treasures reveal new secrets that will help us solve the problems we face today?
Episode 1: “Gems” repeats Wednesday, Aug. 9 at 9:30 p.m. - 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, color, 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 NOVA in the first episode of a three-part series, the TREASURES OF EARTH, as we explore the fascinating science of gems.
