Why Are Lab-Grown Diamonds Cheaper?
Lab-grown diamonds are cheaper because supply is not constrained by geology. A natural 1-carat diamond requires mining millions of tonnes of rock in one of a handful of viable deposits globally. A lab-grown 1-carat diamond can be produced in 2-4 weeks in any country with the right technology.
As more manufacturers entered the market from 2019 to 2026, competition drove prices down by more than 50%. The cost to produce a lab-grown diamond has fallen dramatically as CVD technology has improved and scaled. This is not a reflection of quality. It is simple supply economics.
