Lab-grown diamonds are not merely an alternative but a superior product, being physically identical to mined diamonds in every way and even exceeding them in quality at the high end.
The market for lab-grown diamonds is experiencing exponential, not linear, growth, having already captured the majority of the critical U.S. engagement ring segment.
The value proposition of mined diamonds is built on a false narrative of rarity, which is collapsing in the face of a technologically superior and more affordable alternative.
The economic and environmental costs of lab-grown diamonds are substantially lower, with production requiring only one-fifth of the energy of mining and prices being roughly 70% less for the consumer.
The traditional diamond industry is on the verge of a major structural realignment, evidenced by speculative M&A activity involving key players like De Beers and sovereign nations.
2015
Morrison establishes this year as a baseline, when lab-grown diamonds constituted only 1% of the total diamond market.
2021
According to Morrison's data, the market share for lab-grown diamonds grew to 5%, indicating a slow but steady initial adoption phase.
circa 2025
Morrison refers to 'last year' in her May 2026 appearances, indicating a massive acceleration in market adoption where lab-grown diamonds captured 40% of the total diamond market.
May 2026
During her media appearances, Morrison reports that the market has reached a tipping point, with 70% of all engagement rings sold in the United States now featuring lab-grown diamonds.
Future (<2030)
Morrison predicts that lab-grown diamonds will achieve 75% market share in the U.S. engagement ring sector sooner than The Economist's 2030 forecast.
▶Accelerated Market DisruptionMay 2026
Morrison's primary theme is the rapid and decisive takeover of the diamond market by lab-grown alternatives. She uses stark data points—from 1% market share in 2015 to 40% recently, and 70% of the current US engagement ring market—to illustrate a fundamental and irreversible shift in consumer preference and industry structure.
Investors should view this not as a cyclical trend but as a permanent technological disruption, suggesting that legacy assets and business models in the mined diamond sector face significant devaluation risk.
▶Democratization of Quality and PriceMay 2026
A core tenet of Morrison's argument is that lab-grown technology makes superior quality diamonds accessible at a fraction of the cost. She claims lab-grown diamonds are ~70% cheaper and that their high-end quality now surpasses that of mined stones, effectively decoupling luxury from high price points.
This theme indicates a potential commoditization of the diamond market, where value is increasingly determined by measurable specs (color, clarity, carat) rather than origin, challenging the premium pricing models of traditional luxury brands.
▶Technological and Environmental EfficiencyMay 2026
Morrison highlights the efficiency of lab-grown diamond production, noting the process takes only 4-6 weeks and requires approximately one-fifth of the energy needed for mining. This positions the technology as not only faster and cheaper but also as a more sustainable alternative.
The dual appeal of economic and environmental benefits creates a powerful competitive moat that traditional mining operations cannot easily replicate, making it a key driver for both consumer and regulatory preference.
▶Deconstruction of Industry NarrativesMay 2026
Morrison actively works to dismantle the long-standing marketing myths of the diamond industry. She argues that mined diamonds are not rare and that the distinction between mined and lab-grown is an artificial construct that is undetectable without specialized equipment.
This narrative attack on the perceived 'authenticity' and 'rarity' of mined diamonds is a leading indicator of the erosion of brand equity for legacy companies like De Beers, signaling that their historical marketing leverage is diminishing.
