The diamond industry stands at a tectonic crossroads. While legacy players cling to 20th-century narratives, a perfect storm of technological innovation, ethical imperatives, and generational purchasing power is reshaping the market irreversibly.
Lab-grown diamonds (LGDs) aren’t a passing trend, they’re the catalyst for the most profound transformation since the Kimberley Process.
The Geological Shock: How Science Redefined "Real" -
The Atomic Identity Lab-grown diamonds aren't synthetic simulants like cubic zirconia. They share identical:
Crystal lattice structure (cubic)
Refractive index (2.417)
Dispersion (0.044)
Hardness (10 Mohs) As confirmed by the Gemological Institute of America (GIA)
Manufacturing Breakthroughs -
Method Process Market Share
HPHT 1,500°C / 1.5 million PSI pressure 35%
CVD Carbon plasma deposition in vacuum chamber 65%
