Introduction:

The diamond industry is experiencing its most profound transformation since the Kimberley Process. Laboratory-grown diamonds (LGDs) physically, chemically, and optically identical to mined diamonds have evolved from scientific curiosities to mainstream luxury goods. This deep dive examines the technological breakthroughs, market dynamics, and geological implications reshaping the $90B global diamond industry, with insights from gemological authorities and market data.

The Technological Revolution -

CVD: Atomic-Level Diamond Engineering

Chemical Vapor Deposition (CVD) represents humanity's mastery over carbon crystallization:

Process Deep Dive: Inside quartz reactors, microwaves ionize hydrogen gas (≥99% concentration) into plasma, dissociating methane (CH₄) molecules. Carbon atoms deposit onto diamond seed plates at 800°C, growing at 0.1-10 microns/hour. Critical innovations include:

Recent Milestones:

75.33-carat CVD diamond (Surat, 2024) required 9 months of continuous growth.
