The most colorful gemstones on Earth - Jeff Dekofsky

What gives opals their signature shimmering colors? Dig into the science of the gemstone’s formation, millions of years in the making.--In November 1986, Australian miners climbed Lunatic Hill and bored 20 meters into the Earth. They were rewarded with a fist-sized, record breaking gemstone, which they named the Hailey’s Comet opal. Thanks to a characteristic called “play of color,” no two opals look the same. So what causes these vibrant displays? Jeff Dekofsky digs into the rock’s shimmering, dancing displays of light.Lesson by Jeff Dekofsky, directed by Ivana Bošnjak and Thomas Johnson.Support Our Non-Profit Mission----------------------------------------------Support us on Patreon: http://bit.ly/TEDEdPatreonCheck out our merch: http://bit.ly/TEDEDShop----------------------------------------------Connect With Us----------------------------------------------Sign up for our newsletter: http://bit.ly/TEDEdNewsletterFollow us on Facebook: http://bit.ly/TEDEdFacebookFind us on Twitter: http://bit.ly/TEDEdTwitterPeep us on Instagram: http://bit.ly/TEDEdInstagram----------------------------------------------Keep Learning----------------------------------------------View full lesson: https://ed.ted.com/lessons/the-most-colorful-gemstones-on-earth-jeff-dekofskyDig deeper with additional resources: https://ed.ted.com/lessons/the-most-colorful-gemstones-on-earth-jeff-dekofsky#digdeeperSound design: https://www.campstudio.co/----------------------------------------------Thank you so much to our patrons for your support!
