Diamonds are so popular because they are the toughest, hardest stone in existence. You have to be more careful about what you're putting in a setting and how you're setting it. Opal is something i do not recommend for an engagement ring whatsoever,. It will start to crack if you don't take care of it every day.
Professional gemologist Kelly Sitek 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.
