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

I love the art work, but in a video about optical phenomena in a gemstone, it would have been nice to see an actual demonstration. It's easy enough to look up in other videos, but this video could have driven the explanation home so much better with that one additional thing.

The animation made the gemstones look like mosaic glass and glow like mosaic glass. I LOVE IT, it features one thing about gemstones that i like and its ability to show color in such vibrant and different hues.

Opals are looking insanely same as humans.
None are same. But they are all made from same process.
And one more thing, they look different from different sides.

Maybe that opal mining site in Australia is why they don't want to create a canal through the center to help irrigate the rest of Australia's deserts
