Gemology with Kelly Sitek
Get cozy with professional gemologist Kelly Sitek. She talks about adventures in mining, the chemical composition of different gems, breaks down the test taking process for gemology and gives advice on haunted stones. We also spill some tea on cultured pearls and address the psychology and neurological merits of crystals/the placebo effect. Whether you are a staunch skeptic or all about woo-woo, you may end up shoving a crystal down your pants just for good luck. A.k.a. neural top-down control of physiology.
