What are the key takeaways from this Everything Everywhere Daily episode?

Key insights include: **Production scale growth:** Lab-grown diamond production increased from thousands of carats in early 2000s to over 10 million carats by 2023, representing a thousand-fold increase in two decades.; **Price collapse trajectory:** Lab-grown diamonds dropped from 80-90% of natural diamond prices in mid-2000s to 70-90% below by 2023, with one-carat stones costing $400-800 versus $4,000-6,000 for natural.; **Industrial heat management:** Diamond's highest thermal conductivity of any bulk material makes it ideal for heat sinks in high-power electronics, radio frequency amplifiers, and computer CPUs as production costs decline.
