Why Americans Are Buying Cheaper Diamonds
Lab-grown diamonds have disrupted the traditional diamond market, accounting for 61% of U.S. engagement ring sales in 2026 and causing natural diamond prices to plunge 60% in five years. Major industry players like De Beers are struggling to adapt as lab-grown stones offer lower prices, lower environmental impact, and ethical advantages over mined diamonds.
Summary
The diamond industry is undergoing a seismic shift driven by the rise of lab-grown diamonds. Natural diamond prices have fallen roughly 60% from their March 2022 peak of $10,000 per carat, primarily due to competition from lab-grown alternatives that can be produced in unlimited quantities at a fraction of the cost. Lab-grown diamonds are created by placing diamond seeds in vacuum chambers with carbon-rich gases under controlled heat and pressure, resulting in stones that are chemically and physically identical to natural diamonds. Market adoption has been dramatic, with lab-grown stones accounting for 61% of U.S. engagement ring sales in 2026, representing a 239% increase since 2020. Major retailers like Pandora have completely abandoned mined diamonds, pivoting exclusively to lab-grown stones. Beyond economics, lab-grown diamonds offer significant environmental and ethical advantages—they have a carbon footprint 90% lower than mined diamonds and avoid the complications associated with conflict diamonds, which once represented 4% of global production. However, lab-grown diamonds lack the resale value of natural diamonds, though industry experts argue that natural diamonds also provide minimal financial return. The crisis has forced major industry players to restructure: De Beers paused production at its flagship Venetia mine and shut down its Lightbox lab-grown diamond brand after wholesale prices fell 90%. Russia's Alrosa, accounting for 30% of global diamond production, has also reported declining production between 2023 and 2025. Diamond mining is concentrated in just five countries—Russia, Botswana, Angola, Canada, and the Democratic Republic of Congo—with supply pressured by geopolitical uncertainty, excess inventory, and rising tariffs. Industry analysts suggest the market may be stabilizing at current price levels, with consumers benefiting from the ability to purchase larger stones and redirect savings toward other life priorities.
Key Insights
- Lab-grown diamond prices fell 90% at the wholesale level, forcing De Beers to shut down its Lightbox brand after only 7 years despite launching with an $800 per carat pricing strategy
- Lab-grown stones accounted for 61% of all U.S. engagement ring sales in 2026, representing a 239% increase since 2020
- A lab-grown diamond has a carbon footprint 90% lower than a mined diamond of the same size
- More than 85% of global diamond mining is concentrated in just five countries: Russia, Botswana, Angola, Canada, and the Democratic Republic of Congo
- Mano Rapaport's diamond research indicates the market is around rock bottom with signs of stabilization after the sharp price declines
