Let’s Begin…
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.
What do you think might happen if non-white light was to be shined into a precious opal? What would you expect to see bouncing back through the surface and why?
