- February 14, 2006
Jewel of the Earth is the thirteenth and final episode of the thirty-third season of the educational television series NOVA. In this episode, NOVA explores the as-yet-unanswered question of how the Earth developed its unique and diverse array of minerals and gems.
NOVA takes viewers on a colorful journey through the history of our planet, explaining how billions of years of geological processes, including volcanic activity, tectonic plates shifting, and crystallization, have formed the intricate network of minerals on and beneath the Earth's surface.
Throughout the episode, geological experts utilize advanced technology to gain deeper insight into the formation and distribution of minerals. They use instruments to analyze mineral composition and structure, and investigate the effects of pressure and temperature on the growth of various minerals.
One of the episode's most fascinating segments is a profile of a team of miners in Tanzania who have discovered a massive cache of tanzanite, a beautiful blue-violet gemstone that is found nowhere else in the world. The miners explain how they excavate the unique mineral, and NOVA reveals how the rock formations from which the tanzanite comes were formed over 500 million years ago.
The episode also explores the ways in which minerals can serve as indicators of broader patterns in the Earth's evolution. For example, the presence of tiny green minerals called olivines in volcanic rocks can help scientists deduce the conditions that give rise to volcanic eruptions. By analyzing minerals from different periods in Earth's history, investigators can piece together a more complete picture of how the planet has changed over time.
Throughout the episode, stunning visual effects showcase the full extent and beauty of the various minerals under examination, from brilliantly-colored crystals to intricate mineral lattices. These breathtaking images help to bring the geological story of Earth's minerals vividly to life.
Jewel of the Earth is a fascinating exploration of the formation, intricacy, and beauty of the Earth's minerals and gems. Through interviews with geological experts, mining professionals, and others, the episode offers a comprehensive overview of how geological processes have shaped the planet's mineral diversity. Whether you're a mining enthusiast, a science buff, or simply a lover of natural beauty, there's something in this episode to captivate and intrigue you.
