Introduction: Why Lab-Grown Diamonds Are Disrupting Luxury

The lab-grown diamond (LGD) industry is no longer a niche market, it’s a $30 billion global phenomenon, with China leading the charge as the epicenter of production, innovation, and trade. Between February and April 2025, shifts in inventory and pricing within China’s LGD sector have unveiled critical insights for retailers, investors, and consumers alike.

This report dissects data from China’s top online diamond trading platforms, focusing on IGI-certified round-shaped LGDs, to decode market dynamics. From inventory surges to price volatility, we’ll explore what these trends mean for stakeholders and how platforms like CaratX’s Global Marketplace are revolutionizing access to this booming industry.

Lab-Grown Diamonds 101:

Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds but created in weeks using two primary methods:

High-Pressure High-Temperature (HPHT): Mimics natural diamond formation under extreme heat and pressure.

Chemical Vapor Deposition (CVD): Builds diamonds layer-by-layer using carbon-rich gas.

Why China Leads:

Production Scale: China produces 56% of global LGDs (GIA.edu Report), leveraging cost-efficient HPHT technology.

LGDs generate 30% less carbon emissions than mined diamonds, aligning with global ESG goals (NRDC.org Study).

Consumer Shift: 72% of millennials and Gen Z view LGDs as ethical alternatives (Diamond Development Initiative).
