When you're into crystals as a kid that - at least for me - takes the form of "rock on the side of the road pretty, must take home". When you're into crystals as an adult it comes with all this extra baggage. What's the name of the crystal in your hand? Where does it come from? How much child labor went into getting it out of the ground and into your hands? Does it actually cure my migraines?

Yinan Wang is a geologist and children’s book writer. He is currently studying potential uses of new technology to aid the field of paleontology. He stopped by to have a conversation about the science and salesmanship behind pretty rocks.
