Diamonds on the Express Elevator: The Fast Ride from Deep Earth
About this episode
Diamonds survive a fiery ascent through kimberlite volcanism, powered by a volatile mix of water and carbon dioxide that keeps magma fluid and fuels explosive eruptions. The payoff is a surprising twist: the same system that launches diamonds can carbonize and store CO2 as stable carbonates, producing a negative CO2 footprint per carat in verified cases (about -0.71 kg CO2e). We explore what this means for mining, climate, and the remarkable environmental potential hidden in Earth’s deepest processes.
