Episode Description from the Publisher

Diamonds are formed under a million years of crushing pressure, and for many couples, they're also the ultimate symbol of commitment. Coincidence? Maybe not. That's why we welcomed back couples therapist Zach Brittle, host of the Marriage Therapy Radio podcast. He talks to us about the secret to healthy relationships an – spoiler alert – it's not just vibes or diamond rings. So how did diamonds become synonymous with engagement rings? What are they good for, really? David dives into the history and science of diamonds, including the most successful marketing campaign of all time, industrial uses, and more. I also share perspective as a working jeweler. Check out some of my work on my Instagram @loradorjewelry. Today's game is called Uncut Gems. Players must polish and cut a word by removing the first and last letter to reveal the "diamond" word inside. Check out Zach Brittle’s Website for more info on his podcast and his work. I recommend starting with David and Lisa’s episode, Ep 409 – No One Wins Alone: Lessons in Partnership from Escape Room Experts David and Lisa Spira.     Production Credits Hosted by Peih-Gee Law & David Spira Puzzles by Peih-Gee Law Produced by Theresa Piazza Supported by Lisa Spira Edited by Peih-Gee Law Music by Matt Farthing Logo by Theresa Wagner
