Key Takeaways

✓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.

What It Covers

Synthetic diamonds, chemically identical to natural ones, are now mass-produced using high-pressure or chemical vapor deposition methods, disrupting jewelry markets and enabling industrial applications.
