Oh hey, it's the woman at Costco testing out a hammock, Allie Ward. And this one is for October babies. Anyone who has ever met an October baby too, which is all of you, because the stone of the month for October is flashy, dazzling. Forever young. And Fragile. What are opals?

Why are they so weird? What are they made of? Let's dig into it with a geo scientist and a geophysicist. And yes.

World expert on opals, a professor at the University of Sydney in Australia. Hm. Australia. Ooh, we love an accent. But actually wait. This one might surprise you.
